Three in Pennsylvania infected with novel swine influenza

According to the Pennsylvania Department of Health, two more children in Pennsylvania have become infected with a novel swine influenza A/H3N2 virus that includes a gene from the 2009 pandemic H1N1 virus.
This raises the total to three infections in the state, CIDRAP News reports. All three infected children attended the Washington County Agricultural Fair in southwestern Pennsylvania the week of August 13 to August 20. The first patient, reported on September 2, has recovered and the other two patients are recovering.
On September 2, the Centers for Disease Control and Prevention announced that one child each in Pennsylvania and one in Indiana has been infected with a swine-origin H3N2 virus that included the matrix gene from the 2009 H1N1 virus. The Indiana child may have caught the virus from a caregiver who had contact with pigs.
"We're still investigating what the linkages are here, if it's human-to-human or animal-to-human transmission," Brandi Hunter-Davenport, a PDH spokeswoman, said, according to CIDRAP News.
Investigators from the CDC and PDH have yet to determine exactly how the three Pennsylvania patients became infected. None of the three patients had any direct link to the others aside from attending the fair. The PDH statement said that anyone who attended the Washington County Fair and has flu-like symptoms should contact the health department or their local health provider. State officials said that people should take everyday precautions to prevent the spread of respiratory viruses and should wash their hands after contact with animals at fairs and other places.
"We're not telling people to avoid public venues or fairs," Dr. Eli Avila, the PDH secretary, said in the press release, according to CIDRAP News. "But, until we complete our investigation, we want to make sure that the public is aware and is taking the proper precautions to protect their health."
