Mosquito season has started and the Maricopa County Environmental Services department is advising residents to protect themselves from mosquito bites.
So far this year, Maricopa County Department of Public Health has not received laboratory-confirmation of human cases of West Nile virus infection. Last year, there were 52 WNv human cases and 6 WNv-related deaths documented in Maricopa County. In 2004, Maricopa County led the nation’s counties with 355 people infected with West Nile virus; 16 people died from the disease in Maricopa County.
“We should all be reminded of the simple things we can do that can help us protect ourselves and our loved ones from mosquito bites,” said John Kolman, Director of the Maricopa County Environmental Services Department. “We also need to help prevent mosquitoes from breeding,” Kolman added.
Maricopa County Environmental Services department conducts year-round surveillance of mosquitoes: more than 600 mosquito traps are set throughout the county. These samples are collected throughout the week and tested for West Nile Virus (WNv).
“The more we can control our mosquito population, the more we can control this virus,” said John Townsend, Environmental Services Department Vector Control Division manager. “This is why it is very important that we all do our part to prevent mosquitoes from breeding in our yards and neighborhoods,” said Townsend.
WNv is transmitted to humans by the bite of an infected mosquito. Approximately 20 percent of people infected with West Nile virus will feel flu-like symptoms occurring three to 15 days after the mosquito bite. Symptoms may include fever, headache, nausea, vomiting, swollen lymph glands, and skin rash.
A small percentage of people who are infected with WNv will experience severe symptoms such as meningitis, encephalitis, paralysis or even death. Persons over the age of 50 are generally at a higher risk for severe symptoms. Anyone who thinks they have WNv symptoms should consult their health care provider.
Take these precautions to prevent WNv infection:
•Eliminate mosquito-breeding sites around the home by removing standing water in potted plants, tires, bird baths and other containers where water may collect
•Remove unnecessary clutter
•Repair window and door screens to keep mosquitoes out of the home
•Make sure pools and decorative ponds are properly maintained and operational
“Although this year we have not had any mosquito traps test positive for WNv, we are already seeing an increase in the mosquito population. It is important that we mosquito proof our homes and work with our neighbors to do the same,” Townsend recommended.
Wherever you may be this weekend, bring your insect repellant along and follow label instructions, especially for use on children.
Additionally:
•Wear light colored clothing with long sleeves and pants
•If possible, avoid outdoor activity before dawn and after dusk when mosquitoes are most active
•Use protective clothing and insect repellant when exposure to mosquitoes cannot be avoided
