Status Report
Currently all 50 states and the District of Columbia have one or more public health laboratories qualified to conduct confirmatory testing of the novel H1N1 virus. As a result, delivery of test results has been expedited, leading to improved disease control measures.
As of March 2010, the majority of influenza viruses identified continue to be 2009 H1N1 influenza A viruses. With rare exception, these viruses remain susceptible to the antiviral drugs oseltamivir and zanamivir.
Nationally, visits to doctors for influenza-like illness (ILI) remain relatively low. Laboratory-confirmed hospitalization rates have leveled off. No states reported widespread influenza activity between March 21-27, though regional flu activity has been reported in the Southeast US in recent weeks.
