HANSCOM AIR FORCE BASE, Mass. – The West Nile Virus and Eastern Equine Encephalitis, or EEE, are two mosquito-borne diseases currently of concern in Massachusetts.
Both diseases are transmitted to humans after being bitten by infected mosquitoes.
West Nile Virus is the leading cause of mosquito-borne diseases in the United States.
As of Aug. 24, Massachusetts has had two positive cases of West Nile Virus, and 262 mosquito positive samples across the state.
Symptoms include fever, headache, body aches, nausea/vomiting, diarrhea, and rash. While only about one in five people will develop symptoms, it's important to note that there are no vaccines to prevent or medicines to treat the virus.
EEE is a severe virus that is spread to humans from the bite of an infected mosquito, with very few cases reported each year.
As of Aug. 24, Massachusetts has had one positive case of EEE, and 69 mosquito positive samples.
Symptoms include fever, headache, nausea/vomiting, diarrhea, seizures, behavioral changes, and drowsiness. The virus can cause ongoing neurological problems for survivors and can be fatal. There are no vaccines to prevent or medicines to treat EEE.
Prevention is key to reducing the risk of contracting either mosquito-borne viruses.
Tips include using insect repellent on adults with at least 30% DEET. DEET products should not be used on infants under two months of age and should be used in concentrations of 30% or less on older children.
Additionally, individuals should wear long sleeves and pants, eliminate standing water around homes, and stay indoors during peak mosquito activity (sunset and sunrise).
Anyone who may have recently been bit by mosquitos and are experiencing any symptoms, and have underlying health condition or weakened immune system, are encouraged to seek medical help.
Additionally, for those who have traveled to a region with known outbreaks or to an area with a moderate – Critical risk level, should seek medical attention.
