If you have a sore throat and drips from the nose, aching bones and fever, is clear — you have a cold or in a scientific way Viral respiratory infections (ARI).

What is it?

SARS — a group of diseases combined with four common features.

  1. All of them are infectious. Viruses cause them.
  2. Germs enter the body airborne way — through the respiratory system.
  3. The first step in SARS affects the respiratory system. Not for nothing disease called respiratory, that is "relevant to the breath."
  4. All SARS develop rapidly and continue for long.

Pathogens transmitted by contact with a sick person through the air by coughing, sneezing, talking.

What's going on?

Viruses and bacteria into the respiratory tract, are deposited on the mucosa and start to secrete toxins harmful substances, which are then carried by the blood throughout the body. More often than SARS sick children and people with weakened immune systems. Immunity after the disease unstable, so each man each year get sick 3-4 and more.

SARS usually begins acutely, surprisingly. Between infection and disease, on average it takes about 2 days. Before human disease can be confusing: a feeling of weakness, fatigue, irritability. In the future, these symptoms increase, a headache, severe fatigue, aching muscles, may increase the temperature, sweating develop. May appear: runny nose, sore throat, cough. In some cases, in conjunction with airways disease may have symptoms of conjunctivitis — eye damage.

The more dangerous?

This seemingly innocuous disease can produce serious complications, such as pneumonia, otitis media, sinusitis, heart disease and even meningitis. Against the background of SARS often exacerbated by other existing human disease.

Diagnosis and treatment

Since SARS often occurs in the form of epidemics, the specific causative agent of the disease usually do not even try to detect.

Treatment of SARS is usually done at home under medical supervision. In the hospital the patient is sent only in severe cases or when complications occur.

The patient should be observed bed rest and drink as much as possible, it is desirable to warm tea and fruit drinks. At the high temperature necessary to take antipyretics, if necessary, use an anti-cold drugs or clear your throat.

Good effect in the treatment of SARS makes breathing exercises and vitamin therapy.

Antibiotics for SARS ineffective, so they are taken only on prescription in the case of a bacterial infection or the development of complications.


For the prevention of infection SARS the patient must be isolated from others, provide him with individual dishes, which should be scalding hot water.

For the prevention of influenza each year can be vaccinated.
