Mosquitos are a familiar part of summer, but their bites can be more than just an itchy nuisance. Some mosquitoes can carry viruses that may cause illness, making prevention and early recognition of symptoms important for you and your family. Here are five things to know.
1. Most mosquito bites are harmless, but some can spread disease
The majority of mosquito bites cause nothing more than a temporary itching sensation. However, certain mosquitoes can carry viruses that spread to humans through their bites.
In the United States, the most common mosquito-borne illness is West Nile virus. Other viruses, including dengue, Zika and chikungunya, are more often associated with international travel but have occasionally been identified in parts of the U.S.
The severity of these illnesses can range from asymptomatic to, in rare cases, serious complications.
“It is important to remember that the majority of mosquito bites are not a cause for panic,” said Anjali Sawhney, D.O., a primary care physician with Inspira Health. “However, taking simple preventive steps can significantly reduce your risk and give you peace of mind throughout the summer.”
2. Symptoms can appear up to two weeks after a bite
Symptoms of mosquito-borne illnesses often resemble the flu and may appear anywhere from a few days to two weeks after a bite. Common symptoms include:
- Fever
- Headache
- Muscle or body aches
- Fatigue
- Rash
- Joint pain
In some cases, illnesses such as West Nile virus can lead to more serious complications affecting the brain or nervous system. Seek medical care right away if you or a loved one develops symptoms such as severe headache, confusion, stiff neck, difficulty walking, muscle weakness or seizures.
If you've recently traveled internationally or spent time in an area where mosquito-borne illnesses are more common, be sure to tell your health care provider.
3. Certain people may be at higher risk
Anyone can contract a mosquito-borne illness, but older adults and people with weakened immune systems are at higher risk for severe disease, particularly from West Nile virus. Individuals with chronic health conditions may also be more vulnerable to complications.
Those who are pregnant or traveling with young children should speak with their doctor before traveling to areas where mosquito-borne diseases are more common.
“Prevention is especially important for those whose immune systems may not respond well to infection,” said Dr. Sawhney. “A little extra planning before spending time outdoors can make a meaningful difference.”
4. Prevention is your best protection
The easiest way to avoid mosquito-borne illness is to prevent mosquito bites in the first place. Fortunately, a few simple habits can go a long way.
You can protect yourself by:
- Applying an EPA-registered insect repellent according to label directions
- Wearing long sleeves and pants when possible, especially around dawn and dusk
- Removing standing water from buckets, birdbaths, flowerpots and gutters where mosquitoes breed
- Repairing window and door screens to help keep mosquitoes outside
- Using fans on patios or decks, since mosquitoes are weak flyers
These steps can help reduce mosquito populations around your home while lowering your risk of bites.
5. A primary care provider can help
Most mosquito bites can be treated at home with a cold compress, over-the-counter anti-itch cream and by avoiding scratching the affected area. However, if you develop a fever, rash, persistent fatigue or other flu-like symptoms after a mosquito bite, it's a good idea to contact your primary care provider.
Your primary care doctor can evaluate your symptoms, determine whether additional testing is needed and recommend the appropriate treatment. Prompt medical evaluation is especially important if you've recently traveled internationally or your symptoms become severe.
“While mosquito bites are generally harmless, it’s always important to pay attention to how you’re feeling. If symptoms develop or worsen, seeking medical advice early is always the right choice,” said Dr. Sawhney.
