Blue Cross Urges Louisianians to Protect Themselves from Mosquito Illnesses

BATON ROUGE, La – Mosquito bites are not only itchy and annoying, they can cause serious illnesses. Although rare, diseases like West Nile virus, Zika or encephalitis are caused by mosquito bites. And, the Louisiana Department of Health reports a high number of mosquito pools statewide have tested positive for West Nile virus in recent weeks. 

The most effective way to prevent these illnesses is to not get bitten in the first place. Blue Cross and Blue Shield of Louisiana reminds everyone to take steps to avoid mosquitoes. 

“Don’t be fooled by a mosquito’s tiny size – they are the  deadliest animal in the world,” said Blue Cross Medical Director Dr. Larry Simon. “The World Health Organization estimates that a million people die every year from illnesses they contracted through mosquito bites.”

Mosquitoes breed in standing water, and with Louisiana’s wet, humid climate, swarms are common, especially in the summer months. “These insects are not just pests, they can make you very sick,” Dr. Simon said. “Make sure you’re preventing mosquitoes from getting into and around your home. And, when you’ll be outdoors, take precautions to fight the bite.” 

Steps to Avoid Mosquito Bites:  

Once a week, empty, scrub, turn over, or cover items around your home that hold water such as tires, buckets, pools, flower pots, and planters

Use an outdoor insect spray or bug zapper device that kills mosquitos in places they rest, such as in dark areas, under patio furniture, and under carports or garages

Keep mosquitos out of your home by using window and door screens and using air conditioning when available

When sitting outdoors, use portable fans so air circulates and keeps mosquitoes from landing and biting

Wear long-sleeve shirts and long pants outdoors – bugs typically bite arms and legs

Use an EPA-registered insect repellent that is proven safe and effective

If you have a mosquito bite that looks red or infected, or if you have symptoms of mosquito illnesses like fever, body aches, or rashes without another known cause, see your health care provider.
