Treatment of acute respiratory diseases can be both symptomatic, aimed at alleviating the manifestations of the disease, and etiological, aimed at eliminating the cause of the disease. Fortunately, for the treatment of diseases caused by bacteria, antibacterial drugs or antibiotics have long been successfully used. But in the case of diseases caused by another group of infectious agents viruses, the situation is not so favorable. And there are several reasons for this.
Any virus that has penetrated the body meets with its protective forces immunity. The human immunodeficiency is divided into two varieties: specific and nonspecific. Specific immunity is developed against a specific type of infectious agents, and non-specific immunity has a universal effect and can be directed against any infection. Antiviral drugs, based on the enhancement of immunity, use its nonspecific variety.
The only way to deal with viral infections with antiviral drugs that have a minimum of side effects is vaccination. However, it can not be considered a panacea. It has some limitations because there are a vast number of influenza strains and it is impossible to come up with a vaccine that would be effective against everyone. To some extent, however, this is compensated by the fact that the biological material contained in the vaccines is updated continuously.
