The US is experiencing an outbreak of the West Nile virus, with health officials confirming the first positive mosquito pool for the disease in Philadelphia. According to the Pennsylvania Department of Public Health, the virus was detected in a mosquito sample collected near Pennypack Park in Northeast Philadelphia.
Residents are advised to take precautions against mosquito bites, especially at dusk and night when mosquitoes are most active. The Centers for Disease Control and Prevention (CDC) has assessed the current risk level as ‘low’ with only sporadic virus recorded in mosquitoes and birds.
While most people infected with West Nile virus are asymptomatic, around 1 in 5 patients develop a fever accompanied by headaches and body/muscle/joint pain or rash. Severe cases can occur in about 1 in 150 infected people, particularly among the elderly and those with chronic illnesses.
There is no specific antiviral agent against West Nile virus, but most cases can be treated with rest, fluid, and over-the-counter pain relievers. Hospitalization is necessary for severe cases. Health officials warn that as more mosquitoes test positive for the virus, the risk of human infection increases.
Mosquito control teams are taking measures to mitigate the threat posed by mosquitoes, including fogging areas with higher mosquito activity and conducting targeted larval control in recreational areas. Residents can protect themselves by wearing long-sleeved clothing and pants, especially at dusk and night, when mosquitoes are most active.
