TULSA, OK – [May 17, 2013] – As temperatures rise and people begin to spend more time outdoors, the Tulsa Health Department reminds residents of Tulsa County to take precautions against tick- and mosquito borne diseases including West Nile virus.
The Tulsa Health Department operates a mosquito surveillance program using mosquito traps in various locations throughout Tulsa County in order to confirm when West Nile virus is present in the community. The Tulsa Health Department also works to control mosquito populations during the spring and summer. In a typical mosquito season, THD sprays over 800 square miles for adult mosquitoes.
“Our environmental specialists just finished setting out 75 mosquito traps throughout Tulsa County for surveillance and testing for the West Nile virus,” said Bernard Dindy, environmental health services supervisor. “The objective of our surveillance is to detect the presence of mosquitoes, determine abundance, species, make a risk assessment, and provide a basis for control. We plan on controlling the mosquito population by larviciding and adulticiding when necessary.”
West Nile virus is spread through the bite of an infected mosquito, which feeds on infected birds and then transmits the virus when biting humans, horses, and some other mammals. Symptoms of WNV include sudden onset of fever, headache, dizziness, and muscle weakness. Long-lasting complications can include difficulty concentrating, migraine headaches, extreme muscle weakness and tremors, and paralysis of a limb. If one or more of these symptoms develop, especially after suffering mosquito bites within the previous two weeks, a health care provider should be contacted. Persons over the age of 50 are at greatest risk of developing severe neurologic disease from WNV infection. Some of the neurological effects of WNV may be permanent.
Basic prevention measures include the following:
Remove sources of standing water that mosquitoes require to breed. Empty those items in your yard that can hold standing water so mosquitoes don’t have a place to breed. Birdbaths and animal watering areas should be cleaned and refilled every two to three days, or treated with mosquito dunks to kill mosquito larvae.
Be aware of peak exposure times and places. Exposure to mosquito and tick bites may be reduced by modifying patterns of activity or behavior. Although mosquitoes may bite at any time of day, peak biting activity for mosquitoes carrying some diseases (such as dengue and chikungunya) is during daylight hours. Mosquitoes carrying other diseases (such as malaria) are most active in twilight periods (dawn and dusk) or in the evening after dark. Avoiding the outdoors or focusing prevention activities during peak hours may reduce risk. Place also matters; ticks are often found in grasses and other vegetated areas.
Wear appropriate clothing. When weather permits, people can minimize areas of exposed skin by wearing long-sleeved shirts, long pants, boots, and hats. Tucking in shirts, tucking pants into socks, and wearing closed shoes instead of sandals may reduce risk. Insect repellents, such as permethrin, can be applied to clothing and gear for added protection.
Check for ticks after being outdoors. Conduct a full body check upon return from potentially tick-infested areas, which even includes your back yard. Prompt removal of attached ticks can prevent some infections.
