West
Nile Virus
We have received numerous calls from concerned citizens regarding West Nile Virus (WNV). The West Nile Virus is something
new in the United States and there are many questions that we simply cannot
answer relating to the virus. The following is a list of questions
we have received from constituents regarding the West Nile Virus and wildlife
that we have received.
Can White-tailed Deer become infected with WNV?
-
There are no reports of WNV in deer.
Can Waterfowl or Pheasants become infected with WNV?
-
It appears that waterfowl, pheasants and other game birds
can carry the virus in their blood.
-
In extreme northern Iowa, there have been reports of giant
Canada geese and mallard ducks dying; however, no viable samples of dead
waterfowl have been obtained for testing. There were 6 geese from
a captive flock in Dickson county that succumbed to the virus last month.
-
There has not been an active program to test waterfowl nor
pheasants for WNV.
How is the West Nile Virus transmitted?
-
West Nile is transmitted by the bite of an infected mosquito.
-
The biggest risk to humans is the prolonged exposure to concentrations
of mosquitos where the likelihood of being biten by an infected mosquito
may be greater. Persons that will be spending prolonged periods exposed
to mosquitos should consider applying mosquito repellent to their exposed
skin and clothing. Repellent formulas that contain >= 35% DEET are
recommended.
Can humans contract WNV through handling or eating infected
birds?
-
According to the National Wildlife Disease Center there is
no evidence that just by touching a dead bird a human can contract West
Nile. However, since the virus is a blood-born pathogen, it may be
possible for someone butchering an infected bird to contract the virus
through an open cut on their hand. Therefore, as is recommended when
handling all wild animals, hunters are advised to wear rubber gloves while
dressing out and butchering game birds.
-
As with all food handling, proper cooking of pheasants, ducks
and other game birds is recommended.
Persons with additional concerns regarding WNV should contact
the Iowa Department of Public Health by calling (515) 281-5787.
The Ornithological Council
provides an excellent summary of how people who regularly handle birds can minimize their risk of contracting WNV.
