As Ytro already wrote, in the fall the flu came to the capital ahead of schedule. He was expected in November, but the first surge in incidence It was recorded in mid-September. The reason was two Indian summer (instead of one) – or rather, a sharp cooling between them. Now the epidemic threshold for incidence in Moscow is noticeable exceeded, said Nikolai Malyshev. However, as shown microbiological studies of the flu itself in the capital on almost none at the moment – only a few cases have been identified. So, last week, flu tests were taken from 26 Muscovites, who was diagnosed with this. As a result, the flu virus was found in only three. It turned out that the Russians are mowing parainfluenza. Its main difference from the real flu is that does not acquire stable immunity, which means that he can pick up the same virus several times in one winter. There are three types of walks in Moscow now parainfluenza. All of them, unlike the flu, have a long incubation period – if after infection with influenza may rise the same day or the next, then the first symptoms parainfluenza can appear only after a week. And that means that the patient is able to infect a large the number of people around. Basically, among the sick – children and adolescents aged 7 to 14 years. Parainfluenza epidemic will be declared if epidemic threshold is exceeded by at least 20%; while he is holding at 16%. However, epidemiologists expect an influx of patients already in January – this is, oddly enough, associated with warming. After all, the number of cases of viral infections is minimal it was in frosty, dry weather, Nikolai Malyshev recalled. Real the epidemic, according to doctors, will begin in February. Then to parainfluenza is likely to join the real flu.
