Peripheral blood is characterized with leukopenia, neutropenia, monocytosis, Blood sedimentation rate is not high. Often influenza may result in such complications as pneumonia, frontal sinusitis, genyantritis, otitis.

Recognition of influenza during epidemic is not complicated and is based on clinical and epidemiological data. In interepidemic time influenza occurs rarely and diagnosis may be made with the help of laboratory methods such as distinguishing influenza agent in mucus of mouth and nose with the help of fluorescent antibodies. For retrospective diagnosis are used serological methods.

Patients with uncomplicated influenza are treated at home and are settled into separate room or are isolated from family by a cover. During fever stage is recommended bed regimen and warmth (plentiful hot drink, warmer to the feet). Polyvitamins are prescribed.
