- Hello Jeff...This is what epidemiologists feard. Birds
now will leave Yucatan and head further south into South America. Some
will migrate back north to Canada via the Pacific flyway. This will ensure
WNV hits the US Pacific coast.
-
- This NY99 strain continues to comfound and confuse the
"experts."

- West Nile Virus Detected In Yucatan
-
- El Diario (Nuevo Laredo) (Translation by Mod.MPP) (edited)
-
- (AFP) -- Researchers from the Autonomous University of
the Yucatan detected for the first time in South East Mexico, near Central
America, antibodies against the West Nile virus, according to the entomologist
Julian Garcia.
-
- He said that an analysis of 6 birds captured in the port
of Celestun and in the municipality of Tzucacab, 150 km inland in the Yucatan
Peninsula, led to the discovery of antibodies against flavivirus, the group
to which the West Nile virus belongs. The health authorities of the Yucatan
declared an immediate "epidemiologic alert".
-
- Garcia mentioned that the West Nile virus was detected
for the first time in the Americas in New York State in 1999, and in only
2 years has spread to southern States such as Texas and Florida, precisely
the route which migratory birds such as ducks, bluebirds, swallows and
flycatchers take from the North, arriving on the coasts of Yucatan. The
birds, he added, were infected by the bite of ornithophilic mosquitoes,
which feed only on the blood of birds and are transmitters of the virus.
This is transmitted to humans when mosquitoes such as _Culex pipiens_ bite
the birds and then bite humans.
-
- He advised that the illness can be confused with dengue
fever as its symptoms include severe headache, a febrile state similar
to the flu, swollen glands, neck rigidity and general malaise.

- The statement "the discovery of antibodies against
flavivirus, the group to which the West Nile virus belongs" leads
me to label this finding only "suspected." St Louis encephalitis
(SLE) virus antibodies cross-react with WNV antigen in lab tests -- the
first human cases in the USA were initially confused with SLE for this
reason -- and SLE virus has been recovered from birds all the way down
Central & South America. Next stop for birds flying south from Yucatan
is Colombia & Venezuela. - Mod.JW
