More than 60 pig flu cases registered in Russia


Since the beginning of the epidemiological season 64 cases of pandemic influenza A (H1N1pdm09), or pig flu, have been registered in Russia, reported the Research Institute of Influenza to TASS on Friday.

This information was confirmed by the press service of the Ministry of Health. They noted that several cases of pig flu were registered in Kabardino-Balkaria.

"In general, there are 1292 cases of flu proved with laboratory-based methods in Russia, which is 35.7% of patients sick with ARVI. Laboratory methods have also proved pandemic influenza A (H1N1) pdm09 - pig flu. It was registered in 64 cases which is 1.8% of the sick, explains the Research Institute of Influenza. The majority of patients are infected with influenza A seasonal virus (H3N2)".

Why there is a sharp increase in influenza cases in Russia

According to experts of the Research Institute of Influenza sharp growth of flu cases is caused by changes in the structure of the virus A (H3N2). As the mutated strain of the virus circulates, even vaccinated people can catch it.

"Earlier this week it has been reported on 102 influenza viruses. There are 70 influenza A (H3N2) viruses in Moscow, St. Petersburg, Novosibirsk, Omsk, Kaliningrad, Chita, Vladivostok, Khabarovsk and Ulan-Ude. There are 30 influenza B viruses in St. Petersburg, Novosibirsk, Chelyabinsk, Vladivostok, Kaliningrad, Astrakhan and Stavropol. There are also 2 A / H1N1 (pdm09) viruses - 1 in St. Petersburg and 1 in Vladivostok," noted in the Research Institute of Influenza.

They also added that for the last several days the incidence rate of the flu in 59 cities of Russia has been average.

"Wide spread of ARVI and influenza is registered in Russia as a whole and in 4 districts in particular (the Northwestern, the Privolzhsky, the Ural and the Siberian federal districts), regional spread is registered in the Southern federal district and in the Far East and local spread - in the Central District. In Nizhny Novgorod, Chita and Ulan-Ude flu epidemic began one month earlier than in the previous epidemiological season," said the Research Institute of Influenza.

According to the Ministry of Health, during the seventh week of the epidemiological season (February 9 to 15) "we continue to register the increase in influenza and ARVI cases in the territory of the Russian Federation, especially in the subjects of the Northwestern, the Privolzhsky, the Ural and the Siberian federal districts". "The growth of ARVI cases exceeding weekly epidemic threshold has been registered in 36 subjects of the Russian Federation," added in the press service of the Ministry.

They noted that laboratory monitoring still reveals separation of influenza A(H3N2) and B seasonal viruses, as well as the virus of parainfluenza and adenoviruses.
