2016 Eastern Equine Encephalitis Activity

Eastern equine encephalitis virus (EEEV) is transmitted to humans by the bite of an infected mosquito. Eastern equine encephalitis (EEE) is a rare illness in humans, and only a few cases are reported in the United States each year. Most cases occur in the Atlantic and Gulf Coast states. Most people infected with EEEV have no apparent illness. Severe cases of EEE (involving encephalitis, an inflammation of the brain) begin with the sudden onset of headache, high fever, chills, and vomiting. The illness may then progress into disorientation, seizures, or coma. EEE virus is one of the most severe mosquito transmitted diseases in the United States with approximately 33% mortality and significant brain damage in most survivors. There is no specific treatment for EEE; care is based on symptoms. You can reduce your risk of being infected with EEEV by using insect repellent, wearing protective clothing, and staying indoors while mosquitoes are most active.

2016 Flanders Virus Cases

Flanders virus was discovered in 1961 in the town of Flanders on Long Island, New York. The virus is in the virus family Rhabdoviridae, and it is widely distributed in Canada, the United States, and Mexico. Flanders virus does not cause disease. The virus is frequently found in birds, such as Red-winged blackbirds, House sparrows, and starlings. It is also found in bird-feeding mosquitoes, such as the black-tailed mosquito (Culiseta melanura) and the northern and southern house mosquitoes (Culex pipiens and Culex quinquefasciatus, respectively). Presence of the virus in an area serves as a sentinel or warning for West Nile virus and as a trigger for public health control and prevention interventions targeting West Nile virus.

2016 West Nile Virus Cases

Most people get infected with West Nile virus by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the virus to humans and other animals. In a very small number of cases, West Nile virus has been spread through blood transfusions, organ transplants, and from mother to baby during pregnancy, delivery, or breastfeeding. Recovery from severe disease may take several weeks or months. Some of the neurologic effects may be permanent. About 10 percent of people who develop neurologic infection due to West Nile virus will die.
