West Nile virus, the mosquito-transmitted infection linked at times to severe illness in humans, is all over New York City. Well, 89 ZIP codes of it, anyway. That’s still more than half of the ZIP codes across the five boroughs. Note: Just because your ZIP code doesn’t come up in this table d oesn’t mean there’s no West Nile virus, the health department cautions. The agency put out new data this week, amid its ongoing West Nile remediation efforts, making it searchable for New Yorkers to see if their ZIP codes are on the list. (Get more official background on the virus here.) The virus is transmitted to humans by the bite of an infected mosquito. Those infected may experience mild or no symptoms. Others can develop severe symptoms, including high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness, and paralysis. The symptoms may last several weeks. Neurological effects may be permanent.    Individuals, especially those 50 years or older or those with compromised immune systems, are urged to take precautions to avoid mosquito bites. Last summer, case counts nationally were running 40% higher than normal, health officials said. More than half of the cases were designated severe, according to the U.S. Centers for Disease Control and Prevention.
