CDC, WHO Tracking New Influenza Virus in USA, S-OtrH3N2
Allnurses readers should be aware that a new influenza virus, S-OtrH3N2, has infected 10 individuals in the US since July 2011. It is primarily infecting children, although none of the cases have died. The first seven cases this year were infected by primary or secondary contacts with pigs. But in mid-November, three children in an Iowa day care were infected with no known contact with pigs. It appears that the Iowa cluster represented human-to-human transmission. How this will play out as a novel influenza strain remains to be seen.
