Mosquitoes, the deadly virus transmitted by the bite that affects the brain… This is the alarm raised by the Florida State Department of Health in the United States.
A virus transmitted by mosquitoes that causes brain swelling and can lead to death, detected these days in Florida. It was renamed “eastern equine encephalitis” and was found in“several sentinel hens in the same flock”. The symptoms? Fever, headache, chills, diarrhoea and skin irritation.
“There has been an increase in the activity of mosquito-borne disease in areas of Orange County,“ Department officials said, adding that “the risk of transmission to humans has increased.”
In the last few years in the United States, the average is seven reported cases and the disease is known to be fatal for about thirty percent of the time. This is stated by the Centres for Disease Control and Prevention.
“The people most at risk are those over the age of 50 and under the age of 15,“ the agency said on its website. “Infection with” eastern equine encephalitis “can cause two types of disease: systemic or encephalitic. The latter causes the brain to swell”. People who contract the virus generally start to notice symptoms – including fever, headache, chills, diarrhoea and skin irritation – about 4-10 days after being stung by an infected mosquito.
“The Death usually occurs from two to ten days after the onset of symptoms, but can also occur much later,” says the agency. “Among those who recover, many have reported consequences of mental problems and progressive physical disabilities, which can range from minimal brain dysfunction to severe intellectual disorders, personality disorders, convulsions, paralysis and cranial nerve dysfunction. Many patients with severe sequelae die within a few years.”
Florida health officials have instructed residents to protect themselves by draining and discarding objects in their homes that could retain water and attract mosquitoes, as well as cover themselves with clothes and repellents. “The Department continues to conduct state-level surveillance for mosquito-borne diseases, including West Nile virus infections, eastern equine encephalitis, St. Louis encephalitis, malaria, chikungunya and dengue fever” officials said. “Florida residents are encouraged to report the presence of dead birds through the Florida Fish and Wildlife Conservation Commission website.“
