ATLANTA — The U.S. Centers for Disease Control and Prevention (CDC) is tracking a new strain of the influenza virus that could seriously impact children under the age of 10, according to a press release.
Since August, the CDC has tracked as many as 12 infections with influenza A (H3N2)v, a variant virus with genes from avian, swine and human strains, that had been crossed with an influenza A (H1N1) strain, with 11 of those cases occurring in children under 10, the release stated.
According to the release, the CDC conducted a preliminary analysis to evaluate the age-specific presence of serum cross-reactive antibody in U.S. populations vaccinated or not vaccinated with the 2010-2011 seasonal trivalent influenza vaccine.
The results indicated that little or no cross-reactive antibody to A (H3N2)v exists among children under 10 years, the release noted.
