How not to get sick in winter

C end of the Christmas holidays began a natural increase in the incidence of acute respiratory viral infections (ARI). Start increasing incidence is due, as in previous years, with the return of adults to work and children and adolescents in schools and kindergartens — in organized groups created ideal conditions for the spread of respiratory infections.

In the structure of the incidence of SARS, as usual, there are flu (so far it a bit, but in the near future is expected natural increase in the number of new cases) and parainfluenza and adenovirus, rotavirus, rhinovirus, RSV and other viral infections. Given that each of these infections can be caused by different subtypes of the virus, SARS total number of pathogens in the hundreds.

All respiratory viral infections have a number of similar features allowing to combine them into one group. These features include virus attack the mucous membranes of the respiratory tract (mainly upper) and a set of symptoms such as fever, chills, weakness, headache, muscle aches and joint pain, runny nose, nasal congestion, dry cough, sore throat, and sometimes diarrhea and vomiting. However, the severity of these symptoms vary depending on the type of virus.

The variety of pathogens SARS greatly complicates the specific nature of the treatment and prevention of these diseases. In fact, they are designed only for the most dangerous and the most studied because of respiratory infections — influenza. From it therevaccineand specificantiviral drugs(Neuraminidase inhibitors, such as "Tamiflu" and M2 ion channel blockers, such as "Rimantadine"), but they are not ideal.

Most modern vaccinations recommended by all the people in the absence of contraindications, provide immunity only to the three most prevalent strains of the virus this season, which gives a good, but not a hundred percent preventive effect. The sensitivity of different types of influenza-specific antiviral drug can range from 0 to 99 percent, and to begin taking these drugs should be the first day of illness.

For the rest of SARS vaccines are widely available and specific remedies do not exist yet. Antibiotics are ineffective against viruses.

In this issue of the prevention and treatment of these infections is very serious. According to statistics, ARI are the most common infectious diseases and the leading cause of temporary disability. On average, adults who are infected by them from two to four, and children — from six to ten times per year.

SARS are dangerous by themselves, and the frequent development ofsevere complications. Such complications can be bacterial infection of the middle ear (otitis media), sinuses (sinusitis, sinusitis, etc.), throat (tonsillitis and pharyngitis), trachea and bronchi (bronchitis), lungs (pneumonia). In addition, respiratory viruses can cause lesions of the heart, the brain and the meninges, liver, and lead to infectious-toxic shock and other life-threatening conditions.

According to the WHO, from the "cold" and its complicationsdieabout 4.5 million inhabitants of the earth in a year — more than from any other infection.

In view of this non-specific prevention and treatment of SARS in domestic medicine widely used drugs that enhance and guide the immune response to the infection —immunomodulatorsandimmunostimulators. Most of them increase production in the body natural antiviral agents — interferon.

These substances are secreted by cells of the body in contact with either virus. They "warn" neighboring cells to invade and alter their metabolic processes so that they become less susceptible to the virus and are not involved in its reproduction. Also interferons signal about the source of infection immune cells — lymphocytes and macrophages.

For the synthesis of interferon inducers include drugs such as, for example, "TSikloferon". They are suitable for the prevention and treatment of SARS and influenza, and they can be taken at any stage of the disease. Furthermore, such drugs are well compatible with any other medications used in the treatment of respiratory viral infections.

Because of this, immunomodulators are included in the standard flu treatment developed by the Health Ministry of the Russian Federation and recommended for the prevention and treatment of all types of the disease (including pandemic and highly "bird" flu) Influenza Research and Rospotrebnadzorom.

Contraindications to the use of synthetic interferon inducers little: in most cases it is a question of individual hypersensitivity to the active substances or components of the products. Certainly, the use of any medication should be discussed with your doctor.

And to make it better now, because if you raise immunity in advance where the infection has not occurred, when in contact with the virus will not develop the disease or will proceed in an easy manner. This will avoid complications and to reduce, if not eliminate the cost of treatment.
