Via CIDRAP, Maryn McKenna writes a must-read article: New flu virus may bring summer of discontent. Excerpt:
With summer temperatures settling in across the United States, health authorities are conceding that the novel H1N1 flu virus may continue circulating through the summer, rather than quieting down as seasonal flu strains do.
That could pose major challenges for surveillance of the new flu’s spread, because some important disease indicators, such as school absenteeism, cannot be used during the summer.
It will also tug research on the strain toward an aspect of flu that is not well understood despite years of inquiry: why influenza is a seasonal infection.
The Centers for Disease Control and Prevention (CDC) signaled yesterday that it does not expect the novel virus to mimic seasonal flu’s usual summer hiatus.
“There are some aspects of what we’re seeing that are very different from seasonal patterns,” Dr. Anne Schuchat, the CDC’s interim deputy director for science and public health programs, said at the agency’s Thursday press briefing.
“This virus is circulating much later than the annual flu viruses. We’re really not seeing much of any other seasonal flu viruses anymore. But we are continuing to see this strain circulate, even though of course we’re almost at June.”
