DIKA

ARVI
Under this abbreviation lies an acute respiratory viral infection, i.e., an infection of the respiratory tract caused by viruses.
There are about two hundred varieties of viruses that cause ARVI (the most famous is the influenza virus). All of them are united by the fact that they are very contagious, because they are transmitted by airborne droplets, cause similar symptoms, are not treated with antibiotics.
Symptoms of acute respiratory viral infection are known to all. This is any combination of the following:
temperature increase
runny nose
bronchitis or tracheitis (or both)
headache
malaise
Treatment of acute respiratory viral infection consists of treatment of these manifestations. The temperature can be knocked down by febrifugal, but do not abuse them, as in ARVI temperature is a protective reaction that helps the body fight infection. In addition, the duration of fever more than 3 days at 38 degrees and above can talk about joining dangerous bacterial complications of ARVI (acute sinusitis, acute otitis media, pneumonia) then another treatment is needed, and if the temperature is constantly lowered with the help of medications, this treatment can be late.

Treatment for a cough is described in the section "Bronchitis."
Treatment of the common cold is described in the section called "Runny nose".

Acute Respiratory-Viral Infection!

Inna Grigoryan

Acute respiratory viral infection (ARVI) is a group of viral diseases of the upper respiratory tract. In the process of development, a viral disease can be complicated by a bacterial infection. The main symptoms of acute respiratory viral infections are a runny nose, coughing, sneezing, headache, sore throat, eyeballs, vomiting, loose stools, a feeling of weakness.
In everyday life the word "cold" sometimes refers to the manifestations of herpes simplex on the lips, and not to the disease of the respiratory tract.

Acute respiratory viral infection (Orvi) - a group of clinically and morphologically similar acute inflammatory diseases of the respiratory system, the causative agents of which are pneumotrophic viruses

Valery Zhukov

It's a virus, in general when you catch a cold-tempo and runny nose. Usually, if you start treatment right away, complications do not arise. It is important to choose the right medications, but then these trendy teraflyu, yes, the heart of the rifle is crushed. There phenylephrine is contained, and it forces the heart to wear out to work. I usually drink Antigrippin from a natural product, there is a good composition and it becomes easier quite quickly after it.

I like to experiment, I tried the barrier reef for prevention, I liked it. And the price only seems high - if you count how much we are treating the common cold for treatment, it is clear that it is more profitable. At least on the epidemic, I think it makes sense to carry it with you.

SARS: incubation period. Acute respiratory viral infections (ARVI)

Among multiple diseases, colds occupy, probably, the very first place. After all, these problems worry almost every person several times a year. In this article I want to tell you the main thing about ARVI.

What it is

At the very beginning it is necessary to find out how this abbreviation stands, ARVI. So, this is an acute respiratory viral infection. In this disease, the epithelium of the respiratory tract with RNA- and DNA-containing viruses is affected. It is also worth mentioning that the incidence of this disease increases in the cold season. More often and more easily, the disease affects children aged 3 to 14 years. There are no sex and territorial differences in ARVI (affects both men and women, regardless of where they live).

Kinds

ARVI is a group of viral diseases. So, under the given abbreviation it is possible to mean the following diseases:

1. Flu.
2. Paragripp.
3. Adenovirus.
4. Reovirus.
5. Respiratory syncytial viruses.
6. Parakoklyush.

The incubation period

What you need to know when it comes to ARVI? The incubation period - that's what you need to understand. At the very beginning it is necessary to understand what this term also means. So, the incubation period is the time when the microbe has already entered the human body. But the first symptomatology of the disease has not yet manifested itself.

1. The beginning of the incubation period: the time when a person was in contact with the patient.
2. The end of the incubation period: when the person had the first symptomatology of the disease.

Its duration is different for all diseases. What can you say about ARVI? The incubation period of these diseases is on average from several hours to 14 days. The duration of the course of the disease will be different.

Adenoviruses

If a person has an adenovirus infection (a subspecies of ARVI), the incubation period of this disease is from 2 to 12 days. Further, the development of the disease is quite fast. The first symptomatology: high fever, cough, runny nose. This disease is long, often undulating (the virus has the ability to form new foci). A person for quite a long time can remain a carrier of adenovirus (it is latent in a long time stored in the tonsils).

Respiratory syncytial infection

If to speak about this subspecies of ARVI, the incubation period in this case is from two to seven days. The main symptomatology: a runny nose, pain when swallowing. The temperature rise is very rare, and there is no intoxication. In young children, the disease occurs in a more severe form, the acute respiratory infection penetrates deeper (bronchiolitis). The disease itself lasts an average of 10-12 days. However, there may be a longer course, relapses are not uncommon.

Rhinovirus infection

When a person has a rhinovirus infection (ARVI), how many days in this case will the incubation period last? So, it is about 2-3 days. The main symptoms: a runny nose, watery eyes. Increased temperature and intoxication are uncharacteristic symptoms. Can also be a dry cough.

The incubation period of ARVI in children is the same as in adults. Only the time and nature of the course of the disease can differ. Treatment will be also excellent, because those drugs that adults take, often children are contraindicated.

Characteristics of ARVI

Now we will consider one more urgent topic. It is necessary to consider the main signs of ARVI, so as not to miss the moment of its onset. How does the disease manifest itself?

1. The disease comes slowly. The first symptomatology is not pronounced sharply. Most often it's a cold.
2. The course of the disease has a different time. So, you can cope with the problem for 5-7 days. However, complications and relapses often occur.
3. After ARVI for three weeks a person runs the risk of easily catching another disease.
4. Mortality is very low, only% of patients die from ARVI all over the world (and only those who have not received timely adequate treatment).

The main symptomatology

Having examined the signs of ARVI, you also want to tell about the main symptoms that are typical for this group of diseases. So it can be observed in the patient, when it comes to intoxication:

1. Chills, fever. The temperature can rise up to 40 ° C.
2. Pain: head, muscle.
3. At the very beginning of the illness and during its course the person will feel tired, lethargic. Working capacity is greatly reduced.
4. Often, the patient may increase lymph nodes in the neck and lower jaw.
5. Rashes on the skin or mucous membranes (typical of certain diseases).

If it is a question of a respiratory syndrome (feature of ARVI), the symptoms in this case can be different, depending on the type of the virus and the patient's body. However, we can distinguish typical features:

1. Nasal congestion, runny nose (whitish thick discharge).
2. Dryness in the throat, pershenie, pain (incl. and during swallowing).
3. Lachrymation, photophobia, rubbing in the eyes.
4. Cough. Can be wet, dry, barking.

Complications

If the patient started complicating ARVI, the symptoms in this case will be alarming:

1. Fever, body temperature may exceed the indicator at 40 ° C. Antipyretics often do not have the desired effect on the body.
2. A person can lose consciousness, it can become confused.
3. The patient has severe headaches. Often the head is almost impossible to press against the chest.
4. There may be rashes on the skin in the form of hemorrhages or asterisks.
5. There may be pain in the chest, lack of air, shortness of breath.
6. Cough with expectoration of unusual color: brown, green, red.
7. Edema.
8. The course of the disease is long, the infection can be raging for more than two weeks.

Attention: this symptomatology is alarming. In this case, you need to immediately seek help from a doctor.

Effects

What can be the consequences after SARS? Most often, these diseases are traceless for the body. The exception is complications that can affect one or another body. Especially dangerous are the effects of ARVI for infants, pregnant women and people with weakened immunity.

Prevention

Prevention of ARVI - that's what also needs to be mentioned. After all, it is much easier to prevent a disease than to deal with it in the future.

1. The first moment of prevention is vaccination against influenza.
2. Support the body during a widespread disease can be using immunostimulatory or antiviral drugs. It can be such medications as Aflubin, Anaferon, Arbidol.
3. It is very important to saturate the body every day with the necessary amount of vitamins and trace elements.
4. Also, we must correctly think about the diet, the food should be protein, balanced.
5. Prevention of ARVI is also a rejection of all bad habits, a healthy lifestyle.
6. A good continuous sleep is very important (duration: not less than 7 hours per day).
7. In the season of colds, you need to wear a face mask. Also, one should try to avoid contact with sick people.

SARS is... Acute respiratory viral infection: prevention, treatment

Acute respiratory viral infection (ARVI) is a disease that affects the human respiratory system. The main cause of the disease is contact with viruses. The path of transmission of viruses is airborne.

Prevalence of ARVI

Disease of ARVI is widespread everywhere, especially in kindergartens and schools, work collectives. Increased risk of infection have young children, the elderly and people with a weakened immune system.

The source of infection is an infected person. The high susceptibility of people to viruses leads to a rapid spread of the disease, the SARS epidemic is quite a frequent phenomenon all over the world. Untimely treatment of the disease can lead to various complications.

Outbreaks of respiratory-viral infections occur all year round, but the ARVI epidemic is more often observed in autumn and winter, especially in the absence of quality prevention and quarantine measures to identify cases infection.

Causes of ARVI

The cause of the development of the disease is respiratory viruses, which differ in a short incubation period and rapid spread. The source of the infection is a sick person.

The virus of ARVI is afraid of disinfectants, ultraviolet rays.

The mechanism of development

Getting into the body through the mucosa of the upper respiratory tract or the conjunctiva of the eyes, the viruses, penetrating into the epithelial cells, begin to multiply and destroy them. In places where viruses are introduced, inflammation occurs.

Through damaged blood vessels, getting into the bloodstream, viruses are carried throughout the body. In this case, the body secretes protective substances, the manifestation of which are signs of intoxication. If immunity is weakened, it is possible to attach a bacterial infection.

Symptomatology

All respiratory-viral diseases have similar symptoms. At the beginning of the disease a person has a runny nose, sneezing, pershit in the throat, body aches, the temperature rises, appetite disappears, a liquid stool appears.

Symptoms of SARS in a child can develop rapidly. Quickly increases intoxication, the baby is shivering, vomiting, pronounced hyperthermia. Treatment should be started immediately to avoid possible complications.

Signs of individual viral infections

Determine parainfluenza can be on mucous discharge from the nose, the appearance of a dry "barking" cough, hoarseness of the voice. The temperature does not exceed 38 ° C.

Adenovirus infection is accompanied by conjunctivitis. In addition, the patient may experience rhinitis, laryngitis, tracheitis.

With rhinovirus infection, the symptoms of intoxication are pronounced, the temperature may not rise. The disease is accompanied by abundant mucous discharge from the nose.

For respiratory syncytial viral infection, not pronounced catarrhal symptoms or bronchitis, strong intoxication are characteristic. Body temperature remains normal.

What is the difference between the flu and ARVI?

ARVI begins gradually, the development of the flu is rapid, a person can even indicate the time when he felt ill.

In acute respiratory viral infections, body temperature rises slightly, no higher than 3, C⁰. The flu is characterized by a sharp increase in temperature to 39-40 C⁰. The temperature in this case is maintained for three to four days.

In acute respiratory infections, the symptoms of intoxication are practically non-existent, the person does not shiver and does not throw in sweat, there is no severe headache, eye pain, photophobia, dizziness, body aches, persists operability.

With flu, a strong runny nose and nasal congestion are absent, this is the main symptom of ARVI. The disease is accompanied by reddening of the throat, with a flu such a symptom is not always observed.

In ARVI cough, discomfort in the chest occur at the very beginning of the disease, may be mild or moderately pronounced. The flu is characterized by a painful cough and chest pain that appear on the second day of the disease.

Sneezing is typical for the common cold, there is no such symptom in the flu, but there is redness in the eyes.

After a flu, a person can feel a weakness, a headache, and fast fatigue for another two to three weeks, after such an infection, such symptoms are not preserved.

Knowledge of how the flu differs from ARVI will help a person to assess their condition and take the necessary measures in time to help quickly get rid of the disease and avoid complications.

What are the symptoms of ARVI should alert

Immediately you need to see a doctor when the temperature rises to 40 ° C or more, which does not get knocked off by antipyretic drugs, in cases of mental disorders, intense headache and the inability to bend the neck, the appearance of rashes on the body, shortness of breath, cough with colored sputum (especially with a trace of blood), prolonged fever, edema.

An appeal to a doctor is also necessary if the symptoms of acute respiratory infections do not disappear after 7-10 days. Symptoms of acute respiratory infections in the child require special attention. If any suspicious symptoms occur, you should immediately seek medical help.

Diagnostics

The diagnosis is made by the attending physician after examining the nasopharynx and examining the symptoms. In some cases, complications may require additional research, for example, chest X-ray. This helps to eliminate pneumonia.

Complications

A frequent complication of acute respiratory viral infection is the attachment of a bacterial infection, which provokes the development of inflammatory processes: bronchitis, otitis, sinusitis, pneumonia. The disease can be complicated by the attachment of a urinary tract infection, pancreatitis, cholangitis.

If the disease occurs with pronounced intoxication, the result may be the development of convulsive or meningeal syndromes, myocarditis. Possible neurological problems, such as meningitis, neuritis, meningoencephalitis. After the transfer of acute respiratory viral infections, complications can manifest themselves exacerbation of chronic diseases.

In children, a frequent complication is a false cereal.

To minimize the risk of complications, treatment should begin on time, performing all the doctor's prescriptions.

How to treat

The treatment mostly takes place at home. The patient should adhere to the semi-post regimen, observe the milky-vegetable fortified diet, use a lot of fluids to dilute sputum, stimulate sweating, reduce levels toxins.

But in a furious modern pace, few people follow this rule, preferring to tolerate a cold "on their feet and relieve unpleasant symptoms with symptomatic means. The danger of this approach to treatment is that often symptomatic preparations for cold contain phenylephrine - a substance that increases blood pressure and causes the heart to work for wear. In order to avoid complications of colds, you need to choose medicines without components of this kind. For example, "Antigrippin" (better from "Natur-product") is a preparation for cold without phenylephrine, which eliminates unpleasant symptoms of ARVI, without provoking an increase in pressure and without harming the cardiac muscle.

In the treatment of antiviral drugs, drugs to increase immunity, antipyretic, antihistamines, drugs that help to sputum, vitamins. Locally used vasoconstrictor, which prevents the reproduction of the virus on the mucosa of the nasopharynx. Such treatment is important to carry out at the initial stage of the disease.

Preparations for ARVI treatment

In the fight against the causative agent of the disease, antiviral drugs are effective: Remantadin Amizon Arbidol Amiksin.

Use of non-steroidal anti-inflammatory drugs is necessary to reduce body temperature and reduce pain. These drugs include "Paracetamol" Ibuprofen "Panadol". It must be remembered that the temperature below 38 ° C does not get off, because at this temperature the body activates its protective forces.

Antihistamines are needed to reduce signs of inflammation: congestion of the nose, edema of the mucous. It is recommended to take "Loratidin" Fenistila "Zirteka". Unlike first-generation drugs, they do not cause drowsiness.

Nasal drops are necessary to reduce swelling, eliminate nasal congestion. It is worth remembering that it is not possible to use such drops for a long time, since this can provoke the development of chronic rhinitis. Drops are used no more than 7 days, 2-3 times a day. For long-term treatment it is possible to use preparations based on essential oils.

Remedies for sore throat. It is best in this case to help rinse the throat with the use of disinfectant solutions. For these purposes, you can use sage, chamomile. Rinse often, every two hours. Effective use of disinfectant sprays - "Geksoraal" Bioparox etc.

Cough medicines are needed to dilute sputum. This is helped by the use of the "ACC" Mukaltina "Bronholitin" and others. It is important at the same time to drink a lot of fluid, which also contributes to the dilution of phlegm. The remedies that suppress coughing can not be used without prescribing a doctor.

Antibiotics are not used in the treatment of acute respiratory viral infections, it is necessary only when the bacterial infection is attached.

In addition to medicines, the effective use of physiotherapy, inhalation, massage techniques, foot baths.

Folk remedies

Folk remedies are very effective in treating ARVI. This can be a supplement to the basic treatment and helps to cope faster with the disease. You can use the following recipes.

Not bad helps infusion of fruits of viburnum and linden flowers, which must be crushed and mixed. Two tablespoons of the collection should be poured in 500 ml of boiling water, insist for an hour. The obtained infusion is consumed before going to sleep.

The onion and garlic can be cope well with the disease, which you can simply eat. Both in prophylaxis and in treatment it is useful such a remedy: several cloves of garlic and half a teaspoon of juice are consumed after a meal. You can arrange in the room cut onions and garlic and inhale their vapors.

Very effective remedy for honey and lemon juice. To make it, bee honey (100 g) is mixed with the juice of one lemon and diluted with boiled water (800 ml). The product must be drunk throughout the day.

Prevention

What is the prevention of ARVI in adults and children? To strengthen the defenses of the body you need to temper, lead an active lifestyle, walk in the fresh air, do not disregard rest, avoid stress, and also observe hygiene (wash hands, vegetables, regularly do wet cleaning in room).

Prevention of Orvi in ​​adults requires adherence to the correct diet. The menu should be dominated by natural products. To maintain the intestinal microflora and strengthen the immune system, dairy products are useful. In addition, the diet should be present fiber.

For prophylaxis, you can take antiviral drugs or get vaccinated. Although it is impossible to completely protect yourself with vaccination, as the viruses constantly mutate. Vaccination is recommended for children who attend kindergartens and schools, employees of medical institutions.

In the period of epidemics, it is recommended to limit visits to public places, to strengthen the immunity to take natural remedies or antiviral drugs at the recommended dosage.

If preventive measures have not helped you avoid infection, take care of your recovery, as well as the people around you. Since ARVI is contagious, do not forget to cover your mouth and nose, coughing and sneezing, airing the room, if necessary, wear a gauze bandage. If you follow these measures, the disease will quickly leave your home.

Symptoms and signs of ARVI

ARVI (acute respiratory viral infection) is a group of morphologically and clinically similar acute inflammatory diseases that affect the respiratory system. Pathogens of this pathology are various pneumotrophic viruses, of which there are at least 170 species. The most common viruses are parainfluenza, influenza, adenoviruses, respiratory syncytial viruses and rhinoviruses. If a person has symptoms of ARVI, then he needs treatment, because the disease can lead to the development of bacterial infection.

Each of the pathogens is most affected by one of the sections of the respiratory tract, for example, the parainfluenza virus is the larynx, and the rhinovirus is the nose. This explains the appearance of specific symptoms that help the doctor to make an accurate diagnosis and prescribe the right treatment.

As can be seen in the picture, the main common symptoms of acute respiratory viral infection are headache, fever, chills, muscle aches and weakness. But these are common characteristic symptoms for all types of acute respiratory viral infection, then we will analyze in more detail the symptoms for each type of acute respiratory viral infection, to which includes influenza, parainfluenza, rhinovirus infection, adenovirus infection, and also separately talk about the symptoms of ARVI for children.

Signs of a rhinovirus infection

Rhinovirus infection is also called a contagious rhinitis, because it affects the mucous membrane of the pharynx and nose. The disease can begin both acute and gradual. First of all, there are symptoms of intoxication: muscle weakness, headaches and a feeling of heaviness in the head, chills and malaise amid a slightly elevated temperature.

There are also specific signs of the disease: nasal congestion, perspiration, insignificant hoarseness of the voice, sneezing, difficulty nasal breathing, as well as discharge from the nose, which are initially abundant and mucous, and then - thick, grayish or yellowish hue. Usually this disease does not go through hard and ends with complete recovery of the person.

Signs of adenovirus infection

With adenovirus infection, not only the respiratory organs, but also the lymph nodes, as well as the eyes, occur. The disease begins sharply, with a rise in temperature, which can persist for 7-14 days. There are also symptoms of general intoxication: headaches and muscle pains, feelings of weakness and weakness, lack of appetite, chills. Sometimes there is a breakdown in the bowel function, which aggravates the patient's condition.

The clinical picture of this type of ARVI includes other symptoms: pain with swallowing, perspiration, puffiness eyelids, conjunctivitis, cough, plaque white in the form of films and threads on the palatine tonsils, as well as coarse-grained rash. As soon as the first alarming symptoms of the disease appear, the patient needs to seek medical help, since the risk of developing pneumonia is high.

Signs of respiratory syncytial infection

This pathology is characterized by damage to the bronchi and lungs. And most often it occurs in children, provoking their development of bronchitis and pneumonia. First, the patient has a little fever, there is a runny nose, cough, perspiration and sore throat. Then the patient's condition may worsen, as evidenced by the appearance of the following symptoms:

• severe cough with phlegm;
• dyspnea;
• a significant increase in body temperature.

These signs indicate the development of severe complications - bronchitis or pneumonia.

Signs of parainfluenza

Symptoms of this type of SARS strongly resemble the flu, but for parainfluenza, the heavier upper respiratory tract infection and prolonged course are characteristic. This disease develops gradually, and already on the fourth day there may be complications - pneumonia or bronchitis. Therefore, as soon as the first symptoms appear, you need to see a doctor.

Signs of this ARVI are as follows:

• a sore throat;
• hoarseness;
• headache;
• feeling of weakness and weakness;
• pain when swallowing;
• sweating;
• chills;
• dry, sometimes "barking" and coarse cough;
• a slight increase in temperature;
• aches in the body;
• runny nose.

Sometimes, due to the swelling of the vocal cords and their reflex spasm, breathing difficulties may occur.

Signs of the flu

Influenza causes RNA-containing viruses of genus A, B, C. This disease is characterized by intoxication, not a prolonged febrile period, a lesion of the mucous membranes of the upper respiratory tract.

Influenza is common in both adults and children, especially during the cold season. This disease begins, as a rule, acute, with a rise in temperature to 38-40 degrees and the appearance of severe symptoms of intoxication: the headache pain (and it is localized mainly in the region of the temples, superciliary arches and forehead), weakness, aches in the joints and throughout the body, weakness.

Then there are symptoms of trachea and bronchial involvement - dry cough, perspiration and sore throat, pain and sore throat. The face and neck of the patient become hyperemic, nasal breathing is difficult. Arterial blood pressure decreases slightly, and the heart rate, on the contrary, increases. Sometimes there are nosebleeds and herpes on the wings of the nose and lips.

In adults, fever can persist for five days, after which the patient's condition begins to improve. But this does not always happen, because the flu can cause serious complications, for example, such dangerous as infectious-toxic shock or pneumonia.

The most attention should be paid to the elderly people who are ill with the flu, because they have the highest risk of complications. At them on a background of an infection the existing chronic pathologies can become aggravated, that will essentially worsen their state of health. Influenza is also dangerous for children up to a year, so they should be watched very carefully for their well-being.

Signs of ARVI in the child

In children, the disease begins with a rise in temperature, chills and the appearance of symptoms of intoxication - headache, weakness, lethargy, body aches. The baby can become very moody and irritable.

The child's face becomes hyperemic. The nose of it will be laid, from it there can be plentiful allocation. The baby has perspiration and sore throat, lacrimation, pain in the eyes, and dry or wet cough. When these signs appear in children, you should consult a doctor who knows which symptoms are characteristic for this or that variety of ARVI, and therefore, can establish the correct diagnosis and appoint treatment.

Signs of acute respiratory infections, which require urgent medical help

To many people, ARVI does not seem to be a very serious disease, but this is not at all the case. Symptoms of SARS sometimes take a very dangerous nature. Calling an ambulance is recommended in the following cases:

• rise in temperature from 40 degrees and above;
• no effect of taking antipyretics at a temperature above 38;
• very severe headache;
• appearance on the skin of the rash;
• impairment of consciousness (fainting, confused consciousness, hallucinations);
• pain in the chest, arising from breathing;
• difficulty exhaling or inhaling;
• the appearance of a sputum of a brown or greenish hue or with an admixture of blood;
• feeling of lack of air, shortness of breath;
• edema and pain behind the sternum, not associated with the process of breathing.

Such varieties of ARVI as influenza can lead to complications, especially in elderly people and in young children. And those who suffer from serious chronic diseases (diabetes mellitus, cardiovascular diseases and respiratory pathology), there is a danger of their exacerbation. Complications worsen the prognosis of the disease. and sometimes even become a cause of death.

The incubation period of ARVI

Influenza virus, penetrating the human body, does not immediately make itself felt. Therefore, for the timely detection of the first symptoms and the beginning of treatment, it is desirable to understand how much The incubation period of acute respiratory viral infection, how to determine this condition and what measures can be taken at the very beginning infection. In addition, it will help prevent the infection of surrounding people.

What is the incubation period for influenza and ARVI in adults?

It should be noted that there are many varieties of acute respiratory-viral infections, the type of which depends on the etiology and timing of the development of clinical symptoms. The most common among them:

• flu;
• reovirus;
• respiratory syncytial virus;
• coronavirus;
• adenovirus;
• paragripp;
• rhinovirus;
• Coxsackie virus;
• ECHO virus.

As a rule, all these subtypes of the disease under consideration are similar in features that characterize the acute intoxication of the organism:

• cough;
• coryza;
• swelling of the mucous membranes;
• hyperemia of the skin and mucous membranes;
• temperature increase.

But often there is a mixture of various clinical manifestations, which further provokes the emergence of secondary infectious complications in the form of catarrhalic tonsillitis, pneumonia, bronchitis. Moreover, the development of these diseases can occur directly during the incubation period of acute respiratory infections. In such cases, it is believed that immediately after infection with the virus in the body, intensive multiplication of pathogenic aerobic and anaerobic bacteria began.

How many days is infected with ARVI?

Since the virus enters the body, the person is its carrier, respectively, can infect others, even if the obvious symptoms have not yet appeared. Usually, the flu and other types of described ailment begin quickly and acutely, within 1-3 days, but with strong immunity defenses the incubation can last about a week.

It is worth noting that a patient with acute respiratory infections is contagious throughout the course of the course of the pathology until all cells of the virus in his body die. This means that even with persistent improvements, lowering body temperature to normal values ​​and eliminating external flu symptoms a person still remains a carrier of the disease and can pose a danger to others, because SARS is transmitted easily - airborne by way of.

How long does the incubation period of ARI and ARVI last?

First of all, it is necessary to clearly understand the difference between these two diseases.

In acute respiratory infections, there is a local lesion, most often - the respiratory tract, without a significant increase in temperature (rarely exceeds 38 degrees). The disease progresses slowly and does not spread to other organs, the symptoms of intoxication are either weak or not pronounced at all.

Influenza and SARS are characterized by a sharp, intense onset, with a rapid onset of signs of ailment. In addition, these pathologies cause several groups of clinical manifestations at once:

• from the gastrointestinal tract (vomiting, nausea);
• upper respiratory tract (cough, sore throat, nasal congestion);
• 
• nervous system (migraine, insomnia).

The main difference between the considered respiratory diseases is that the cause of ARVI is mandatory is a viral infection, and the patient is infectious for a long period of time, whereas ARI does not have these qualities are inherent.

The incubation period of influenza, as already indicated, is short, and in ARI it can be up to 14 days. In this case, the condition of the victim is relatively normal, and the temperature increase is sometimes or completely absent, or reaches a low-grade value.
