Prevention and Treatment
No vaccine or drug treatment is available at this time, although research is ongoing and several experimental vaccines and antiviral therapies are showing promise. Vaccines for similar flaviviruses have been developed to protect humans, so it may not be a difficult task to produce one for WNV in the next few years.
Treatment currently is focused on symptom management. In more severe cases, admission to a hospital may be required. A more effective solution is preventing infection by protecting against mosquito bites by using insect repellent, wearing long-sleeved clothing and trousers, staying indoors at dawn and dusk, and eliminating standing water sources that attract mosquitoes.
