While some of the tropical viruses spreading into the United States are a result of climate change, West Nile Virus most likely came to the United States via global travel or trade, said Kwit. In Ohio, West Nile virus was first identified in birds and mosquitoes in 2001.
According to a press release from MCPH, there have been no human cases reported so far this year in Miami County, but OH has seen two human cases in Ross and Lake counties. So far there have been none reported in Jefferson and Orleans Parish. Collibbe says it's possible the health issues were caused by West Nile virus.
Moreover, the virus can be risky for young children, people who are more than 65 years and those who have a weak immune system. County workers then capture and test mosquitoes from those areas to see whether they're infected. After every rainfall, tip out water in flowerpots, planters, children's toys, wading pools, buckets, and anything else that may be holding water. Make sure swimming pools and fountains are operational and circulating.
Limit outdoor activities during dusk and dawn to prevent mosquito bites.
Use effective insect repellent such as DEET or Picaridin.
8, North Dakota reported 18 human cases, up 14 cases since July 30.
Symptoms of West Nile include joint pain, headaches, muscle aches, nausea and a stiff neck.
Approximately 80 percent of people who are infected with West Nile virus will not show any symptoms at all, but there is no way to know in advance if you will develop an illness or not. In a small number of cases, especially among those with pre-existing medical risk factors, West Nile can be life threatening. The severe symptoms may last several weeks, and neurologic effects may be permanent.
This season, mosquito samples have tested positive for WNV in the cities of Addison, Balch Springs, Coppell, Dallas, Desoto, Garland, Highland Park, Irving, Mesquite, Richardson, Rowlett, and University Park. Less than 1 percent of people who are infected will develop a serious neurologic illness such as encephalitis or meningitis (inflammation of the brain or surrounding tissues).
