<div><font color="#000000">WEST NILE VIRUS UPDATE & RESOURCES --
July 10, 2002</font></div>
<div><font color="#000000"><br></font></div>
<div><font color="#000000">West Nile Virus has been<b> detected</b> in
the US in at least 20 states and Washington DC; as well as in Ontario,
Canada; and in mosquitoes in the Negev Desert in Israel. Its range has
expanded in each of the 4 years since the initial North American
outbreak in 1999, and is expected to continue to expand in 2002. 
However, thus far in the season, Texas is the only state where WNV has
been detected for the first time in 2002 (first ann June 19, now
detected in horses, birds, mosquitoes).  [See the list below of
states and locations in Canada where WNV has been
detected.]</font></div>
<div><font color="#000000"><br></font></div>
<div><font color="#000000">In many places WNV has been detected
significantly earlier this season than previously. For example,
WNV-positive birds were not found in Massachusetts until mid-July
2001, 7 weeks later than in 2002; and were not found in Canada until
August 2001, as compared with late May 2002.  In previous years
WNV-positive mosquitoes were not detected in Israel until mid-summer,
whereas in 2002 they were detected in early May.</font></div>
<div><font color="#000000"><br></font></div>
<div><font color="#000000">A year ago at this time (July 10, 2001),
WNV was found only in 7 states (Connecticut, Delaware, Florida,
Maryland, New Jersey, New York, and Rhode Island) and 2 years ago,
had  been detected only in New Jersey and New York at this point
in the year.  A year earlier (3 years ago) WNV had not yet been
detected in the US, although by the end of 1999 it had been detected
in 4 states, primarily within 75 miles of New York City (NY, NJ,
Connecticut, Maryland). By the close of 2001 WNV was detected in 27
states and by the end of 2000 it was in 12 states.</font></div>
<div><font color="#000000"><br></font></div>
<div><font color="#000000">If confirmed, the first and thus far
only<b> human case</b> in 2002 is a 78-yr-old man from SE Louisiana,
near the Mississippi border.  Reports of<b> equine cases</b> are
inconsistent, but it appears that 7 cases are scattered throughout
Florida, 1 case has been confirmed from central Kentucky, 6 cases have
been confirmed from southwest Louisiana, and 1 case from eastern
Texas.</font></div>
<div><font color="#000000"><br></font></div>
<div>In some areas where West Nile Virus is showing up for the third
and fourth year, there seems to be a growing complacency about taking
precautionary and preventative measures.  Although fortunately
WNV has not caused widespread human mortality--as was initially feared
by some--it can cause unpleasant (flu-like) and sometimes long-lasting
symptoms in people.  It also presents a serious risk to
unvaccinated horses.  Protection measures are illustrated on a<b>
poster</b> *  newly issued by Cornell's Environmental Risk
Analysis Program.</div>
<div><br></div>
<div>ERAP's West Nile Virus web pages contain much additional
user-friendly information about the disease, transmission, protection
measures, educational materials, etc. (<font

(2nd edition) contains photos of Culex mosquitoes at each stage of
development (egg, larva, pupa and adult) and practical information
about mosquito control at each life stage. Ordering & preview
