West Nile Virus

Mosquitoes in Lincoln have tested positive for West Nile virus, marking the start of seasonal risk in our area. As of June 19, no human cases have been reported, but the presence of the virus means it’s important to stay aware and take precautions.

West Nile virus spreads through the bite of an infected mosquito. Not every bite leads to illness, but when infection does occur, symptoms can appear anywhere from 2 to 14 days later.

Most People Won’t Feel Sick

The majority of people infected with West Nile virus do not develop symptoms. About 80 out of 100 people will feel completely fine after being bitten.

Some people, about 20 out of 100, may develop West Nile fever, which is usually mild. Symptoms may include:

• Fever
• Feeling very tired
• Headache
• Muscle aches or weakness
• Neck pain or stiffness
• Eye pain
• Loss of appetite
• Nausea or vomiting
• Rash

These symptoms often last 3 to 6 days, though some people may continue to feel unwell for weeks or longer.

When to Take Symptoms Seriously

In rare cases, fewer than 1 out of 100 people infected, West Nile virus can lead to severe illness that affects the brain or nervous system.

Warning signs may include:

• High fever
• Severe headache
• Stiff neck
• Confusion or disorientation
• Tremors or convulsions
• Muscle weakness or paralysis
• Vision changes

If you or someone you know experiences severe symptoms, seek medical attention right away.

When to Contact Your Provider

If you develop symptoms after a mosquito bite, especially fever, fatigue or headache, it’s a good idea to check in with your healthcare provider. They can help determine if testing is needed and rule out other possible causes.

You should contact a provider promptly if symptoms aren’t improving, last longer than expected or feel more intense than a typical mild illness.

West Nile virus is diagnosed through a blood test, and early evaluation can help ensure you get the care you need.

Testing and Treatment

West Nile virus is diagnosed through a blood test.

There is no specific treatment to cure the virus. Care focuses on helping the body recover, which may include rest, fluids and, in more serious cases, hospital care.

Prevention is Best

The most effective way to avoid West Nile virus is to prevent mosquito bites and reduce mosquito populations around your home.

To protect yourself:

• Use insect repellent when outdoors
• Wear long sleeves and pants
• Avoid being outside at dawn and dusk when mosquitoes are most active
• Make sure window and door screens fit properly

To reduce mosquitoes, you should start by removing standing water where mosquitoes lay eggs, such as in buckets, birdbaths and old tires. You should also keep outdoor areas free of water buildup.

Taking these simple steps can help protect you and your family from West Nile virus and other mosquito-borne diseases this summer.
