From January 14 to 20, two deaths resulting from the A/H1N1 virus were reported as the city entered peak flu season, but a massive outbreak is unlikely, Xie Hui, director of the disease control department of the Beijing Municipal Health Bureau said.
A/H1N1 flu-related deaths have been reported every week this month in Beijing.
In addition to the A/H1N1 virus, the A/H3N2 virus is also currently spreading, according to relevant epidemic pathogen tests, state-run Xinhua news agency reported.
The A/H1N1 flu outbreak peaked in 2009.
More than 120,000 A/H1N1 flu cases were recorded that year in the Chinese mainland, with 648 cases resulting in deaths.
Wang Quanyi, head of the epidemic prevention institute under the Beijing Centres for Disease Control and Prevention, said people were not immune to the A/H1N1 virus in 2009, when the virus spread globally.
Now that the A/H1N1 virus has become an ordinary seasonal flu and people have become immune, an outbreak is very unlikely, Xinhua quoted Wang as saying.
