Understanding Mosquito-Borne Diseases in the Pacific Northwest: EEE, West Nile, and Malaria

The Pacific Northwest is known for its lush landscapes and temperate climate, but with the beauty of our region comes the potential risk of mosquito-borne diseases. Recent news has highlighted concerns about Eastern Equine Encephalitis (EEE), West Nile Virus, and even the rare appearance of malaria. While these diseases may sound alarming, understanding the differences between them can help you stay informed and protect your family.

Eastern Equine Encephalitis (EEE)

What It Is: EEE is a rare but serious disease caused by a virus transmitted through the bite of an infected mosquito. It primarily affects horses but can also infect humans.
Symptoms: Symptoms of EEE in humans can range from mild flu-like illness to severe neurological issues, including encephalitis (inflammation of the brain), which can be life-threatening. Symptoms typically appear 4-10 days after being bitten.
Risk in the Pacific Northwest: While EEE is more common in the eastern United States, the presence of this virus in the Pacific Northwest is rare but possible. The recent news is a reminder to remain vigilant, especially in areas with large mosquito populations.

West Nile Virus

What It Is: West Nile Virus is the most common mosquito-borne disease in the United States. It is transmitted to humans through the bite of an infected mosquito.
Symptoms: Most people infected with West Nile Virus do not develop symptoms. However, about 1 in 5 people may experience fever, headache, body aches, joint pains, vomiting, diarrhea, or a rash. In rare cases, the virus can lead to serious neurological conditions such as encephalitis or meningitis.
Risk in the Pacific Northwest: West Nile Virus has been detected in mosquitoes and birds in the Pacific Northwest, making it the most relevant mosquito-borne disease in our region. Late summer and early fall are typically when cases are most common.

Malaria

What It Is: Malaria is a disease caused by a parasite transmitted through the bite of an infected Anopheles mosquito. While malaria is typically found in tropical and subtropical regions, there have been rare instances of local transmission in the U.S.
Symptoms: Malaria symptoms include fever, chills, headache, muscle aches, and fatigue, and they can appear 7-30 days after being bitten. Without treatment, the disease can progress to severe illness.
Risk in the Pacific Northwest: Malaria is extremely rare in the Pacific Northwest. The recent news of malaria cases in the U.S. is related to isolated incidents, often linked to travel. However, it’s important to be aware of the symptoms, especially if you have recently traveled to areas where malaria is common.

Protecting Yourself and Your Family

While the risk of these diseases in the Pacific Northwest varies, it’s always wise to take precautions to reduce your exposure to mosquito bites:

Use Insect Repellent: Choose an EPA-approved insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
Wear Protective Clothing: Long sleeves and pants can help protect your skin from mosquito bites.
Eliminate Standing Water: Mosquitoes breed in standing water, so be sure to empty water from containers around your home.
Stay Indoors During Peak Mosquito Hours: Mosquitoes are most active during dawn and dusk. Try to limit outdoor activities during these times.
