Health officials in East Pierce County are investigating a potential first case of locally acquired malaria in Washington state. A woman who had not recently traveled was diagnosed with the disease on August 2 and is currently receiving treatment.
The Tacoma-Pierce County Health Department, in collaboration with the Washington State Department of Health and the Centers for Disease Control and Prevention, is working to determine the source of the infection. Dr. James Miller, Tacoma-Pierce County Health Officer, suggested that the most likely cause is a mosquito biting someone with travel-associated malaria and then transmitting the infection.
Malaria is a rare disease in the US, but can be life-threatening if not diagnosed and treated promptly. The CDC reports approximately 2,000 to 2,500 cases annually, with Washington state reporting 20 to 70 cases each year primarily linked to travel.
To prevent mosquito bites, health authorities recommend using EPA-registered insect repellent, wearing long-sleeved clothing, and using screens on windows and doors. Travelers to malaria-endemic countries should consult healthcare providers about preventive measures, including medications.
