How is WNV transmitted?
West Nile Virus FAQsThis is a blood-borne disease transmitted by blood-sucking insects, primarily mosquitoes, most commonly the species Culex pipiens. Mosquitoes become infected after feeding on the blood of a bird that is carrying the virus. Infected mosquitoes may then transmit WNV to humans and other animals. Yes. By the end of 2001, there had been 149 human cases of WNV reported and confirmed in the US, including 18 fatalities.

Q&A - West Nile virus: Signs, Symptoms, TransmissionWest Nile virus cannot be spread through casual or intimate contact, such as touching or kissing a person with the virus. Little information is known. There is some speculation that the mosquitoes primarily responsible for WNV transmission may not be present in large numbers at altitudes above 8,000 feet. However, until more is learned about the mosquito populations at higher altitudes, the best recommendation is to protect yourself at all altitudes.
Related QuestionsWHAT IS WNV?
Environmental Health and Lab: Madison Department of Public H...West Nile Virus is a virus that was first identified in Uganda in 1937. This virus was first identified in the United States in 1999 during an outbreak in New York. Since that time, the virus has been found in mosquitoes, birds, horses, and humans in various locations in the United States.

The bacterium which causes Legionnaire's disease is normally present at low levels in potable water supplies. Under the right conditions (particularly moderately hot water temperatures, from about 90 to 130 degrees Fahrenheit, and in the presence of nutrients), its population may greatly increase. If droplets of contaminated water get into the air and are inhaled by a susceptible individual, he may contract the disease.
Related QuestionsFrequently Asked Questions About Chronic Wasting DiseaseNeither the agent causing CWD or its mode of transmissions have been identified. Experimental and circumstantial evidence suggests infected deer and elk probably transmit the disease through animals-to-animal contact and/or contamination of feed or water sources with saliva, urine, and/or feces. CWD seems more likely to occur in areas where deer or elk are crowded or where they congregate at man-made feed and water stations. Artificial feeding of deer and elk may compound the problem.Related Questions
HOW CAN I BE EXPOSED TO WNV?
Environmental Health and Lab: Madison Department of Public H...People may be exposed to WNV when an infected mosquito bites them. However, only a small percentage of mosquitoes are expected to carry the virus so the risk of being infected with WNV from any single mosquito bite is very small. For a mosquito to become infected with the virus, it must bite an infected bird.
Related QuestionsHow are STDs transmitted?
FAQSTDs can be transmitted through oral, anal or vaginal sex. They can be transmitted from partner to partner with or without visible signs or symptoms.

Environmental Health and Lab: Madison Department of Public H...No. Monitoring data in the United States have indicated that mosquitoes in the Culex group are most often infected with WNV. This is significant because most of the nuisance mosquitoes in Madison belong to the Aedes group, which are less likely to carry the West Nile Virus. Culex mosquitoes found in the Madison area (usually Culex pipens or Culex restuans) are considered to be evening and nighttime biters and commonly breed in stagnant or polluted water.
