Influenza is one of the types of ARVI, to determine it, you need to pass a special analysis.
And the treatment of ARVI is classic for all types - antiviral drugs, for example, Viferon suppositories ... They quickly dissolve in the rectum and begin to work - block the multiplication of viruses and protect healthy cells from infection.
This helps to reduce the duration of the acute period and the likelihood of complications.
Because in order to diagnose the flu, you need to know that the symptoms are caused by a specific strain of the influenza virus, and such laboratory analysis requires money.
In addition, influenza tests are not conclusive when making a diagnosis of influenza. because false negative results are common.
Even if your test is negative, if you have significant symptoms and disease activity in your area is high, your doctor may diagnose you with influenza.
Therefore, such an analysis is not of great practical value for a particular person.
Because you can't just put it, you still need to prove it in the laboratory, and this possibility is not everywhere. And if there is, it costs money, which, as you know, is nowhere to be found, funding has been reduced, they save on everything. So it's easier to write ARVI than to bear the cost of laboratory diagnostics. SARS can be distinguished from influenza - the temperature during the flu keeps and does not go astray for 3-4 days above 39 degrees.
