As summer begins across the U.S., so does a quiet but growing health threat—West Nile Virus (WNV). This mosquito-borne virus has already been detected in several states, and health officials are warning that infections may rise significantly in the coming months.
While most people infected with WNV won’t show symptoms, the virus can lead to serious illness or even death in certain cases. Understanding the risks and how to protect yourself is critical—especially if you live in an affected area.
What Is West Nile Virus?
West Nile Virus is the most common mosquito-borne disease in the continental United States. It’s primarily spread through the bite of an infected mosquito, which typically acquires the virus from birds.
The virus tends to peak during the late summer months, especially between July and September, when mosquitoes are most active.
Why Is It a Problem Right Now?
So far in 2025, mosquito populations carrying WNV have been found in Texas, California, Arizona, Illinois, and Louisiana.
While no human cases have been confirmed yet, the risk of infection is increasing rapidly, with recent rainfall and high temperatures accelerating mosquito breeding and activity.
Symptoms of West Nile Virus
About 80% of people infected with WNV show no symptoms. However, 1 in 5 may develop mild symptoms, and a small number may experience severe, life-threatening conditions.
Symptom Comparison:
| Mild to Moderate Symptoms | Severe Symptoms |
|---|---|
| Fever | High fever |
| Headache | Stiff neck |
| Joint and body aches | Disorientation |
| Vomiting or diarrhea | Muscle weakness |
| Skin rash | Vision loss or coma |
Who’s at Highest Risk?
Some groups face higher risk of serious complications from West Nile Virus due to weakened immune systems or underlying conditions.
| High-Risk Groups | Why They’re Vulnerable |
|---|---|
| Adults over 60 | Age reduces immune system effectiveness |
| Cancer patients | Chemotherapy suppresses immune response |
| People with diabetes | Chronic inflammation increases susceptibility |
| Organ transplant recipients | Use of immunosuppressants lowers defense |
| Kidney disease patients | Overall health is often compromised |
8 Ways to Protect Yourself From West Nile Virus
The most effective way to avoid West Nile Virus is by preventing mosquito bites and limiting exposure. Here’s how:
1. Use Insect Repellent
Apply EPA-registered repellents that contain:
- DEET
- Picaridin
- Oil of lemon eucalyptus
2. Wear Protective Clothing
Dress in long-sleeved shirts, long pants, and light-colored clothing to reduce mosquito attraction.
3. Avoid Mosquito Peak Hours
Mosquitoes are most active at dawn and dusk. If possible, stay indoors or take extra precautions during these times.
4. Eliminate Standing Water
Mosquitoes lay eggs in stagnant water. Empty or clean:
- Flower pots
- Buckets
- Birdbaths
- Clogged gutters
5. Use Window and Door Screens
Fix or replace torn screens to keep mosquitoes from entering your home.
6. Use Air Conditioning
Staying in cool, air-conditioned spaces limits mosquito exposure indoors.
7. Treat Gear and Clothing
Apply permethrin to clothing, tents, and outdoor gear. Do not use permethrin directly on skin.
8. Report Breeding Areas
Notify local authorities if you find mosquito swarms or standing water in public places or vacant lots.
Strengthening Your Body’s Natural Defenses
Even with preventive measures, occasional bites are hard to avoid. Supporting your immune system can help reduce the risk of serious illness if infected.
A combination of healthy lifestyle choices and science-backed natural supplements may improve your immune resilience.
Explore trusted immune support options that combine ingredients like vitamin C, zinc, elderberry, and echinacea, all known for their role in strengthening immunity.

Frequently Asked Questions (FAQ)
1. Can you get West Nile Virus more than once?
Most people develop immunity after infection. However, reinfection is rare but still being studied.
2. Is there a vaccine for West Nile Virus?
No vaccine is currently approved for humans. Prevention remains the best strategy.
3. Can pets be infected with West Nile Virus?
Yes, especially horses. There are vaccines for horses, but not for dogs or cats.
4. What should I do if I suspect I have WNV?
Seek medical attention promptly. Diagnosis is confirmed through blood tests, and severe cases may require hospitalization.
5. Where can I track WNV cases and activity?
Refer to your local health department or visit the CDC’s West Nile Virus page for updated maps and alerts.
