Symptoms associated with West Nile virus typically appear 3 to 14 days after infection.
"This indicates that West Nile infected mosquitoes are now present throughout our community", Dr. Sarah Moyer, director of the Louisville Metro Department of Public Health and Wellness, said in a statement.
"Mosquito-borne diseases overall are increasing", CDC spokeswoman Kate Fowley told weather.com. Limit outdoor activities and take precautions to prevent mosquito bites during these times. Spraying clothes with repellent will give extra protection - seeing as some mosquitoes bite through clothes. A very small proportion of human infections have occurred through organ transplant, blood transfusions and breast milk. Last year, there was one non-fatal human case. There were no reported cases of West Nile in the county a year ago. According to World Health Organisation, there is one reported case of transplacental (mother-to-child) WNV transmission.
"The symptoms are the same as that of Japanese Encephalitis or Meningitis". The rain and flooding often leave standing pools of water, creating flawless mosquito breeding grounds. Preventative measures include wearing long-sleeved shirts, long trousers, and using mosquito repellant containing an EPA-registered active ingredient, such as DEET or Picaridin. According to the Centers for Disease Control and Prevention, most people infected with the virus may not show any symptoms but some may experience fever along with body aches, joint pain, headaches, vomiting and diarrhoea. Fix or replace screens with tears or holes. "Get rid of even small amounts of standing water around your home". The use of mosquito nets can be useful at night, particularly for infants.
