The article discusses the influenza cases in the U.S. during October 3, 2010-February 5, 2011. It claims that during the period, around 140 World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) have tested respiratory specimens for influenza viruses, of which 19.5% were tested positive. Seventy-three percent of the positive cases were influenza A viruses and 27% were influenza B viruses.
