A new strain of swine flu has shown up in two children in Pennsylvania and Indiana who had direct or indirect contact with pigs. The virus includes a gene from the 2009 pandemic strain that might let it spread more easily than pig viruses normally do.
So far, there is no sign that the virus has spread beyond the two children, the Centers for Disease Control and Prevention reported Friday.
People rarely get flu from pigs — only 21 cases have been documented in the past five years — and it’s too soon to know how infective this virus will be, the CDC said.
The new strain is a hybrid of viruses that have infected pigs over the past decade and a gene from the H1N1 strain that caused the pandemic two years ago.
