At present, has gradually entered the high incidence of flu season, facing the arrival of cold air, cold growing number of hospitals. Many people are concerned about, Yantai have the flu this year it? In this regard, Yantai City CDC pass anti-chief Liu Jingyu said that at present, there are two Yantai influenza sentinel hospitals in the detection of influenza samples, respectively, Yantai Fushan District, Yantai Hill Hospital and People's Hospital, according to the latest test results show emergence of influenza virus this year, although a month earlier than last year found, but no influenza cases increased significantly compared with previous years. Currently, the City of flu to H3N2 (Influenza A H3N2) primarily, the virus has not variation.

Liu Kechang tell jellyfish nets (http://www.shm.com.cn/), according to the characteristics of the virus, influenza virus in Yantai possibility of causing large-scale spread of epidemic persists, the other movements of the influenza virus has a very high unpredictability, is likely to happen to other types other influenza outbreaks, so the city's flu prevention and control situation is still not optimistic.

Although H3N2 is far less than the risk of H1N1, but the public, especially people with chronic underlying diseases, or good protection. Liu Kechang reminded the public that a fever for more than 38 ℃, sore throat, cough, flu-like symptoms that should be timely medical treatment of.

"Window ventilation is very important, a classroom if there is one person to carry influenza virus, do not open the window, then it is easy to cause the spread of the flu virus outbreak." Liu Jingyu said the flu incubation period is usually 1-3 days, patients and latent infection That person is infectious from the incubation period, the incidence of three days is most contagious, spread mainly through droplets through the respiratory tract, can also be spread through indirect contact with contaminated hands, everyday appliances.

in tropical Asia, influenza activity continued to decrease or remained low with influenza B
predominant in India and Viet Nam.

The WHO GISRS
laboratories tested more than 31 820 specimens. 1318 were positive for influenza viruses, of
which 778 (59%) were typed as influenza A and 540 (41%) as influenza B. Of the sub-typed
influenza A viruses, 46 (11%) were influenza A(H1N1)pdm09 and 374 (89%) were influenza
A(H3N2). Of the characterized B viruses, 28 (100%) belonged to the B-Yamagata lineage and
0 (0%) to the B-Victoria lineage
