The U.S. Centers for Disease Control and Prevention (CDC) is urging people to take steps to prevent mosquito bites as the West Nile virus season begins earlier and more intensely than usual. Reporting from multiple outlets says the current outbreak period is the earliest and among the strongest starts since tracking began in 2004. The CDC’s guidance emphasizes reducing exposure to mosquitoes, particularly during peak biting times, and using protective measures such as insect repellent, wearing long sleeves and long pants, and removing standing water where mosquitoes can breed. Health officials are also encouraging communities to stay alert for symptoms of West Nile virus, which can include fever, headache, body aches, and in more severe cases neurologic illness. While most infections do not result in serious disease, officials note that severe illness can occur, especially in older adults and people with certain medical conditions. The CDC’s message focuses on prevention while the situation develops throughout the mosquito season.
