A woman from East Pierce County has been diagnosed with malaria after returning from her travels. The risk of getting infected with the disease remains low, according to Dr. James Miller, Tacoma-Pierce County Health Officer. Malaria is a rare disease in the US, and most cases occur when people travel to countries with ongoing transmission.
Malaria is caused by a parasite transmitted through mosquito bites. Symptoms include fever, chills, and fatigue. The incubation period is 7-30 days. If left untreated, malaria can be life-threatening.
The US sees about 2,000-2,500 cases of malaria linked to travel each year, with most occurring in Washington state. However, the first locally acquired mosquito-transmitted case in 20 years was reported in 2023. To prevent malaria, it’s essential to prevent mosquito bites and ensure early diagnosis and treatment.
The best ways to protect yourself include using EPA-registered insect repellents, wearing long-sleeved clothing, and installing screens on windows and doors. Removing standing water sources can also help reduce mosquito populations.
Health officials are working with the Washington State Department of Health and Centers for Disease Control and Prevention to investigate the source of infection. They urge travelers to take steps to prevent malaria, such as taking medication before traveling and seeking medical attention immediately if symptoms occur.
The Tacoma-Pierce County Health Department’s mission is to protect and improve the health of all people and places in Pierce County through policy, programs, and treatment.
