West Nile virus rampant in the South Bay, health officials say

Key Points:

• West Nile virus human cases in Los Angeles County have reached a 10-year high, with the South Bay area accounting for about 25% of cases, nearly all progressing to neuroinvasive disease.
• The virus, transmitted by female culex mosquitoes from infected birds to humans, can cause severe neurological damage, paralysis, or death, especially in the elderly and immunocompromised, with no current vaccine or specific treatment available.
• Hospitals in the South Bay, including Torrance Memorial and Kaiser Permanente South Bay Medical Center, have reported significant increases in cases and deaths compared to previous years, highlighting a rising public health concern.
• Experts emphasize the importance of mosquito control, public awareness, and early hospital visits for symptoms like fever and severe headaches, while calling for increased funding and research into vaccines and treatments despite challenges due to the virus's relative rarity.
• Residents are urged to use preventive measures such as insect repellents, eliminating standing water, and ensuring window screens are intact to reduce mosquito exposure during the peak transmission season from May to November.
