West Nile Virus surveillance begins

West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird.

Collecting and testing dead birds is an important component of the West Nile Virus (WNV) surveillance program.

West Nile Virus generally appears in birds and mosquitoes before it is transmitted to humans; therefore, monitoring bird populations helps to predict when and where humans will be at higher risk for West Nile Virus infections.

The Bureau, Putnam, Marshall County Health Departments are now accepting dead birds for testing of WNV. The public is encouraged to help locate birds that may have died from the disease. Sick birds or birds that have been dead less than 12 hours may be eligible for testing. To qualify for testing, birds must meet these guidelines:

• Birds must be dead less than 12 hours (fresh) and the carcass must not have obvious signs of trauma (struck by a vehicle, window or animal attack), decay or strong odor. Birds dying from WNV are usually found singly, scattered over a wide area. In contrast, birds that die from other causes (storm mortality, food poisoning, toxicants) often die in groups or clusters.

• Eligible birds include: Crows, blue jays, house finches, house sparrows, robins; Perching birds such as blackbirds, bluebirds, catbirds, cardinals, goldfinches, finches, swallows, wrens; hawks and owls.

• Ineligible birds include: Waterfowl, gulls, vultures, turkeys, chickens or eagles.

• Only adults should handle dead birds. Pick the bird up with gloves, tongs or a shovel. If you do not have gloves, insert your hand into a plastic bag like it is a glove, grasp the bird carefully and invert the bag over the bird. Each bird should be double-bagged in clear plastic bags.

The Bureau, Putnam and Marshall County Health Departments urge the public to take precautions to protect you and your family from mosquito bites. Outbreaks of West Nile Virus (WNV) occur each summer in the U.S., warmer temperatures mean more mosquitoes. Take these common precautions to minimize mosquito bites this summer:

• Avoid being outdoors at dusk/night and early morning, when winds are light and mosquitoes are active.

• When outdoors during these times wear light-colored clothing and apply insect repellent.

• Ensure that doors and windows have tight, properly fitting screens.

• Eliminate all sources of standing water that support mosquito breeding (i.e. bird baths, wading pools, flowerpots, tires, cans, buckets, clogged gutters, abandoned swimming pools, etc.) on your property. This is especially important because large numbers of mosquitoes that carry WNV can emerge from even one shallow containers of stagnant water.

• For additional information regarding WNV or to submit a bird for testing, please call Bureau, Putnam and Marshall County Health Departments at 815-872-5091 or 309-246-8074, to determine if the bird is eligible before you touch or handle it.
