As of July 31, 2007, a total of 22 states have reported 185 cases of human West Nile illness to the CDC, including 60 WNV-associated brain infections and 5 deaths. Comparatively, by July 18, 2006, 10 states had reported 15 cases of human WNV.

The American College of Emergency Physicians is concerned over the increase in cases, especially as August and September is the peak mosquito season and yet to come.

In a written statement, ACEP president Dr. Brian Keaton said: “Given the jump in reported cases, along with the minute chance of developing life-threatening illness, we are asking people in areas where it is prevalent to become familiar with the incidence and symptoms of West Nile Virus and to take extra precautions against mosquito bites.”

The hardest-hit states so far are California with 42 cases of WNV infection, South Dakota with 38, North Dakota with 14, Mississippi with 13, and Nebraska with 12.

Common symptoms include fever, headache and body aches, nausea, vomiting and sometimes swollen glands or a skin rash on the chest, stomach and back.

Avoiding mosquito bites is the best precaution. Some measures include using insect repellent or having areas sprayed professionally; eliminating standing water around the home where mosquito can breed; wear long-sleeves and pants when outdoors; repair screens on doors and windows to keep mosquitoes out.
