MASSACHUSETTS - Ben Gianakos and Ransford Pest Control say the mosquito prevention business is buzzing. The area's recent heat and humidity has only led to more of the winged nuisances. 

"Also, we've had a lot of rain, which means standing water, which means it's easy for the mosquitoes to breed and have a much higher population," Gianakos said. 

The Centers for Disease Control and Prevention are sounding the alarm this summer. In a health advisory, the CDC reported more than double the number of cases of dengue fever in the Americas this year when compared to last. 

The disease, which is transmitted through mosquito bites, can lead to fevers, rash, head or muscle aches, and in severe cases, even death. CDC experts say there is a risk by age, with a higher risk to infants as well as elderly populations 

Dengue is more commonly found in more tropical climates, like the Virgin Islands, and Puerto Rico. While cases in the U.S. have been limited, the CDC says small outbreaks have been seen recently in the states. 

The city of Worcester is reminding residents this summer of the 5 D's of mosquito prevention: Dress in long sleeves when possible, use deet repellant when outside, dusk and dawn are when mosquitoes are most active, and lastly drain water from any containers weekly. 

"If you're having a party, say you're going to be out on a deck or patio area, one thing that helps is setting up some fans where that air can blow away from the property or away from the party, and that will help prevent the mosquitoes from coming into that airflow," Gianakos said. 

The CDC says roughly 400 million people are infected annually, and one in four cases are symptomatic. 

Gianakos says while he hasn't had experience with Dengue, it is something on their radar along with EEE and the West Nile virus. He expects to be doing mosquito prevention work until mid-October.  

"Even treating at the end of October is very important, because that's building on the reduction for the following year," Gianakos said.
