Mosquito Bites Can Lead to Serious Illness
Getting bitten by a mosquito used to be nothing more than an itchy nuisance. But over the past couple of decades, that has changed dramatically. Mosquitoes are now spreading serious diseases like never before, and a simple bite can have life-altering consequences. Jane recently had the misfortune of being bitten by a mosquito carrying one of these dangerous diseases. Her experience highlights the growing threat posed by mosquitoes and other insects, and shows why we all need to take steps to protect ourselves.
The Bite That Changed Jane's Life
Jane was enjoying an evening cookout with friends in her backyard when she suddenly felt a sharp sting on her arm. She looked down to see a mosquito sucking blood from her skin. Jane quickly slapped it away, but the damage was already done. At first, she didn't think much of it. Mosquito bites were a common summer nuisance she was used to dealing with. This one seemed no different than any other.
Over the next few days, however, Jane started feeling unusually tired and achy. She developed a high fever, chills, and drenching sweats. Jane decided to go to her doctor, who ran some tests. The diagnosis came back positive for West Nile virus, which is transmitted by mosquitoes. Jane was shocked that such severe symptoms could come from a simple mosquito bite.
West Nile Virus on the Rise
West Nile virus first appeared in the United States in 1999. Since then, it has spread across the country and infected thousands of people. About 1 in 5 who are infected develop symptoms like Jane had. In rare cases, it can be fatal. There is no vaccine or cure for West Nile virus. Treatment focuses on relieving symptoms until the infection passes.
West Nile cases peak during summer and fall, but the risk continues any time mosquitoes are active. Experts say hot weather, heavy rain, and bird migration all contribute to outbreaks. Urban areas are particularly prone to West Nile virus since mosquitoes breed in standing water and thrive in heat.
Cities have tried to curb West Nile transmission by spraying insecticides and eliminating breeding grounds. But so far, the virus remains deeply embedded in mosquito populations. Jane was dismayed to learn she got West Nile virus from a mosquito in her own backyard. It made her realize how vulnerable we all are.
Taking Precautions Against Mosquito Bites
After recovering from her bout with West Nile virus, Jane wanted to make sure she never went through that again. She started taking precautions to avoid mosquito bites by:
- Using EPA approved insect repellent when going outdoors
- Wearing long sleeves and pants at dusk/dawn when mosquitoes are most active
- Getting rid of standing water in her yard where mosquitoes breed
- Installing screens on windows and doors to keep mosquitoes out
- Avoiding being outside at peak mosquito times
Jane also makes sure her family and friends take steps to prevent mosquito bites. She doesn't want anyone else to get sick like she did. Mosquito control has become a top priority for Jane during the warmer months.
The Emergence of Zika Virus
While West Nile virus remains the most common mosquito-borne disease in the U.S., a new threat called Zika virus emerged in recent years. Zika is closely related to West Nile and is spread by the same mosquitoes. Most people with Zika have mild symptoms, if any. But Zika can cause severe birth defects in babies whose mothers were infected during pregnancy. There is no treatment or vaccine for Zika.
Zika first appeared in the Americas in 2015. Brazil was hardest hit and saw thousands of babies born with Zika-related birth defects. By 2016, locally transmitted Zika cases were being reported in parts of the southern U.S. as the virus spread northward. Zika has since declined, but experts warn it could resurge seasonally, like West Nile virus.
Traveling Safely to Zika Zones
Since there is currently no Zika virus spreading locally in the U.S., the only way to get it here now is by traveling to an affected area or having sex with an infected partner. The CDC has identified a number of regions globally that pose a risk:
- Mexico, Central America, South America, and the Caribbean
- Parts of Africa and Asia
- Some Pacific islands
Pregnant women are advised not to travel to those regions. Others are cautioned to take strict precautions against mosquito bites. The only foolproof way to prevent Zika is avoiding mosquitoes entirely when traveling to high-risk zones.
A New Reality of Mosquito-Borne Illness
For most of human history, mosquito bites have been an annoyances rather than a major health threat. But as Jane's experience shows, that is no longer the case. Mosquitoes are growing as vectors of dangerous diseases that can cause severe illness and birth defects.
Climate change is allowing mosquitoes and the pathogens they carry to expand into new regions. International travel helps spread viruses globally before we realize the threat. And suburban development creates ideal mosquito habitat that facilitates transmission to people.
We must adapt to this new reality that mosquitoes are no longer just a nuisance but a potentially deadly danger. Taking preventive measures, eliminating breeding areas, and monitoring spread of new viruses will be crucial to reduce the risk of additional mosquito-borne disease outbreaks. Through vigilance and proactive efforts, we can stem the surge of infections and protect people's health.
Jane's life was forever changed by one fateful mosquito bite. Her story serves as a cautionary tale we all need to take to heart. It is no longer enough just to swat away mosquitoes and forget about it. Those bites could have consequences. We must treat all mosquitoes as the threatening vectors they have become if we hope to avoid new health crises.
Staying safe from mosquitoes will be the new norm as we adjust to the unsettling reality that these once harmless insects now frequently spread serious illnesses. By spreading awareness and taking preventive actions, we can turn the tide against the mounting threat posed by mosquitoes.
FAQs
How do mosquitoes spread viruses like West Nile and Zika?
When a mosquito bites someone who is infected with West Nile, Zika, or other viruses, it can pick up the virus and pass it on to the next person it bites. The viruses multiply inside the mosquito's body before being injected via saliva into the new host.
Where in the U.S. am I most at risk for mosquito-borne diseases?
Southern and Western states, especially Florida, Texas, and California, have more locally transmitted cases of mosquito diseases like West Nile and Zika. However, any state where mosquitoes are present carries some degree of risk.
When are mosquitoes most active?
Mosquitoes tend to be most active at dawn and dusk because they avoid the midday heat. Peak biting times are typically early morning and early evening. Mosquito activity increases after heavy rains as well.
What repellents work best against mosquitoes?
DEET, picaridin, IR3535, and oil of lemon eucalyptus are all EPA-approved insect repellents proven effective against mosquitoes. Follow instructions on the label for proper application.
How can I reduce mosquitoes around my home?
Eliminate any standing water which allows mosquitoes to breed. Use screens on windows and doors. Avoid being outside at peak times. Consider professional pest control if necessary.
