HUMAN WEST NILE CASE IDENTIFIED

Delaware’s Division of Public Health today identified the state’s first reported human case of West Nile virus for 2011 in a 71 year-old man from New Castle County. The case was identified by tests conducted at the Delaware Public Health Laboratory in Smyrna. The individual has underlying health conditions and is hospitalized.

West Nile virus is transmitted by the bite of infected mosquitoes. Humans infected with West Nile virus typically have symptoms similar to a mild flu, if they show any signs at all. Rarely do humans infected with the disease experience more severe symptoms of sudden onset of severe headache, high fever, stiff neck, confusion and muscle weakness. Individuals with these symptoms should see their physician immediately. Delaware’s first confirmed human case of West Nile virus occurred in 2002. During 2003, 17 human cases, were reported. There were no reported human cases in 2004 but two were reported in 2005.

Follow these procedures for mosquito prevention:

• Avoid outdoor activities at dusk when mosquitoes are more active.
• Wear shoes, long-sleeved shirts, and pants. Use mosquito netting to protect the face and neck or to cover infant strollers and playpens. Apply repellents as for tick prevention.
• Maintain window and door screens to prevent mosquitoes from entering the house.
• Remove standing water to prevent mosquito breeding: Regularly drain tarps and pool covers. Store wading pools, wheelbarrows and buckets upside down. Change water in birdbaths, pet dishes and potted plant saucers.
• Regularly clear gutters, drains, ditches and culverts.
