WEST NILE VIRUS (WNV) AND ITS CONTROL
West Nile virus (WNV) is a mosquito-borne disease that can cause encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord). Symptoms include rapid onset of severe headache, high fever, stiff neck, confusion, loss of consciousness, and muscle weakness. Statistics from the Centers for Disease Control and Prevention (CDC) demonstrate that more than one-third of the reported cases of WNV result in some degree of lasting neurological damage. In the worst cases, the disease can be fatal. WNV was first detected in the United States during 1999 in the New York metropolitan area when 62 people became sick and 7 died. As of 2014, the disease has spread throughout the continental United States, resulting in a total of 41,762 human cases, including 18,810 neuroinvasive disease cases and 22,952 non-neuroinvasive disease cases resulting in 1,765 deaths.
The Middlesex County Mosquito Extermination Commission recognizes WNV to be a clear and present danger to the health, safety, and well-being of its residents and visitors, and is committed to providing protection from infection through coordinated efforts including surveillance for virus activity and a comprehensive and integrated approach to mosquito control. The Commission’s mosquito control strategy adheres to the guidelines for WNV surveillance, prevention, and control, as set forth in the current recommendations of the CDC, and conforms to the guidelines for phased response to WNV surveillance data.
