"Historically, reports of people becoming ill from West Nile virus peak in August and September", said Sarah Mattes of PHMDC.
Half of the deaths were registered in Bucharest, with the other three being reported in Buzau, Braila, and Olt. In addition, 86 WNV positive mosquito pools have been detected in seven MI counties and eight horses have tested positive in seven counties.
Although the chances of developing serious symptoms from the West Nile Virus are slim, it's still important to protect yourself, Hougaard said.
"West Nile is transmitted to humans and animals through the bite of an infected mosquito", he said.
Try to stay indoors when mosquitoes are most active (dusk to dawn).
According to the Central Massachusetts Mosquito Control Project, while evening temperatures have begun to decline across the state, residents should continue to avoid mosquito bites regardless of where they live until the first hard frost.
Public health officials have warned this could be a bad summer for West Nile virus. About one in five infected persons will have mild illness with fever, and about one in 150 infected people will become severely ill. Most people with this type of illness recover completely, but fatigue and weakness can last for weeks or months. Some people have symptoms of illness that may range from mild fever to encephalitis or mengioencephelitis, according to the health department.
Less than one percent of those infected develop severe neurological illness like encephalitis or meningitis.
Wear shoes, socks, long trousers and a long-sleeve shirt when outdoors for a long period of time.
Dispose of water-holding containers, such as ceramic pots, used tires, and tire swings.
Officials recommend using mosquito repellent, wearing protective clothing, emptying standing water where mosquitoes could breed and using screens.
"The higher wind from a fan will help keep the mosquitoes from landing on you", said Hausbeck.
