CDC: We are tracking swine flu virus in five states and we expect more
The Centers for Disease Control and Prevention announced Friday that it has identified the second case of human infection of swine flu.
Since August, 12 people have been infected with the virus, called H3N2, in Indiana, Iowa, Maine, Pennsylvania and West Virginia. CDC officials announced that they found another case of human infection with a swine-origin H3N2 virus, this time in a child from West Virginia.
Details of the investigations into the West Virginia case and one spotted in the fall in Indiana were released late Friday.
“The 2009 H1N1 virus was likely transmitted to swine from humans during and after the 2009-2010 pandemic and now is commonly spreading in both humans and in swine,” the CDC said in a statement. “Given that, and the ability of influenza viruses to change, it is not surprising to see influenza viruses that normally circulate in swine acquire gene segments from the 2009 H1N1 virus. In fact, monitoring of influenza viruses circulating in swine has indicated that the 2009 influenza H1N1 virus has reassorted with other swine influenza A viruses as well.”
The announcement comes as the CDC warned that they expect to find additional cases of swine flu in the coming weeks. CDC officials said they working with state health officials in order to reveal additional cases of swine flu. The health agency also noted that it is recommending that clinics who suspect influenza virus infection in humans with recent exposure to swine test patients for timely diagnosis at a state public health laboratory and consider antiviral treatment.
