Prevent Mosquito Bites

Aedes aegypti mosquito



Staying at home or traveling abroad this summer? Protect yourself and your family from mosquito bites that can make you sick.
Summer is finally here! Think backyard BBQs, swimming, and mosquitoes…Mosquito bites can be more than just annoying and itchy. They can make you really sick. Whether you and your family are staying at home or heading overseas, remember to wear your insect repellent. Wearing insect repellent is the best way to prevent diseases spread by mosquitoes.

West Nile Virus (WNV)

In the United States, West Nile is the most common virus spread through mosquito bites. Mosquitoes that spread WNV bite at night from dusk to dawn. There are no medications to treat or vaccines to prevent WNV infection. Fortunately, most people infected with WNV will have no symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms. Less than 1% of infected people develop a serious, sometimes fatal, neurologic illness such as encephalitis or meningitis (swelling of the brain or surrounding tissues). In 2014, 48 states and the District of Columbia reported over 2,200 cases of WNV.

Chikungunya

The most common symptoms of chikungunya virus infection are sudden onset of a high fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Infection with chikungunya virus is rarely fatal, but the joint pain can often be severe and debilitating. Most patients recover in about a week, although long-term joint pain occurs in some people. Infection is thought to provide lifelong immunity. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans.
In late 2013, chikungunya virus was found for the first time in the Americas on islands in the Caribbean. Since then, almost 1.5 million cases have been reported. There is no vaccine to prevent or medicine to treat chikungunya virus infection. Mosquitoes become infected when they bite someone already infected with the virus. Infected mosquitoes can then spread the virus to other people. In 2014-5, 2,662 cases of chikungunya were reported in the continental U.S., most imported by travelers. Puerto Rico and the U.S. Virgin Islands also had large outbreaks.

Dengue

Forty percent of the world's population lives in an area at risk for dengue and an estimated 390 million people per year are infected with the viruses. Dengue is a disease caused by one of four viruses: dengue virus 1, 2, 3, and 4. Because there are four different viruses, it is possible for someone to get dengue up to four times. Dengue is a leading cause of illness and death in the tropics and subtropics.
Like WNV and chikungunya, there is no vaccine to prevent or medication to treat a dengue infection. Most infected people infected with dengue have mild or no symptoms. About 25% of people who are infected with dengue will develop some symptoms of disease. Mild symptoms of infection begin with a fever and severe headache, pain behind the eyes, joint and muscle pain, and rash. Dengue symptoms can quickly become severe and even fatal. Early recognition of severe disease, followed by close management by a healthcare provider is critical.
When used as directed, insect repellents are the BEST way to protect yourself and family members from getting sick from mosquito bites.
