New York City Health Commissioner Neal L. Cohen, MD, has issued a statement
saying the city's "prevention-focused efforts are very much on track."
That includes citywide attempts to kill the eggs the hibernating adults will
Gubler says there's also action to be taken on a community level. "It
isn't strictly just the government's responsibility," he says. "People
should be aware, they should clean up their backyards, get rid of any potential
mosquito-breeding places. If they've got swimming pools, take good care of
them. They should be aware of how to reduce the risk of mosquito bites and
follow that .. they should definitely not be alarmed, but they should be
Ultimately, Gubler says no one knows how resilient the WNV is going to be,
they just know what it has done in the past in places like Africa and
elsewhere. It's thought that the natural home for the virus is in the tropics,
so when it appears in northern areas it usually hangs around for a year or two
and then disappears. "So we really don't know how resilient it is, whether
it's going to persist through the winter in the New York area. That's why
[there's] the need for the intensified surveillance."
- The CDC reports it has found traces of the genetic building blocks of the
West Nile Virus, after investigators searched pools of hibernating mosquitoes
in New York. Last year, the virus killed seven elderly people and sickened many
others there. No live virus has been found so far this year.
- CDC specialists say the discovery does not surprise them, since the virus
has been known to hibernate during winter months.
- Officials say the virus usually emerges in the tropics. When it occurs in
the North, it usually lasts for a year or two then disappears. The CDC doesn't
know if this will happen in this case, and preventive measures are underway in
New York, such as spraying to kill mosquito eggs.
