Understanding Symptoms and Risks of West Nile Virus Infection
Learn about West Nile virus symptoms, risks, and prevention methods. Early signs include fever and fatigue, while severe cases can lead to neurological issues like encephalitis. Vulnerable groups include older adults and those with underlying health conditions. No specific vaccine exists, so mosquito control remains vital. Seek medical attention promptly if symptoms develop to ensure proper care and recovery.
Understanding Symptoms and Risks of West Nile Virus Infection
West Nile virus is transmitted through mosquito bites, leading to West Nile fever. Symptoms usually appear between 2 to 15 days after infection, though many individuals remain asymptomatic, with about 80% showing no signs initially.
Early signs include fever, headaches, and fatigue. More evident symptoms can encompass muscle aches, nausea, loss of appetite, vomiting, and rashes. Some cases may result in prolonged febrile illness lasting weeks or months.
In severe cases, neurological complications such as encephalitis or meningitis may develop, affecting the central nervous system. Notable symptoms include numbness, paralysis, vision problems, muscle weakness, seizures, confusion, neck stiffness, high fever, headaches, and disorientation.
Individuals with underlying health issues like hypertension, diabetes, kidney disease, or cancer are at increased risk. Transplant recipients also face higher susceptibility. Older adults, especially those over 60, tend to experience more severe symptoms and longer recovery times.
Recovery can take from weeks to months, and some neurological effects may be permanent. While no specific antiviral treatment or vaccine exists, mild cases are managed with pain relievers, and severe cases require hospital care with IV fluids and supportive treatment. Preventing mosquito bites is essential to curb infection spread.
