The Maryland Department of Health has confirmed and reported a positive case of locally acquired malaria in a Maryland resident living in the National Capital Region. The person was hospitalized and is now recovering. They have not recently traveled outside the United States or to other US states with recently locally acquired malaria cases.

“Malaria was once common in the United States, including Maryland, but we haven’t seen a case in Maryland in more than 40 years that isn’t travel-related,” said Laura Herrera Scott, secretary of the Maryland Department of Health. “We are taking this very seriously and will be working with local and federal health officials to investigate this matter.”

Malaria is a mosquito-borne disease caused by a parasite. According to the Centers for Disease Control and Prevention, there are more than 2,000 cases of malaria in the United States annually, most of which occur in people returning from international travel. Maryland typically reports about 200 travel-related malaria cases each year, and the Maryland Department of Health investigates each case for cause and risk.

Symptoms of malaria usually appear 7 to 30 days after the infective bite and include high fever, chills, body aches, diarrhea and vomiting.

“Malaria can be very dangerous and even fatal if left untreated, but early treatment reduces the chances of complications,” said Dr Nilesh Kalyanaraman, deputy secretary of public health services. “We urge the public to exercise caution against mosquito bites, and seek immediate medical care if you develop symptoms after traveling abroad.”

According to the Centers for Disease Control and Prevention, the risk to the public for locally acquired mosquito-transmitted malaria is very low. However, Marylanders can take these precautions to prevent mosquito bites or travel-related malaria:

Use insect repellent containing DEET on exposed skin.

If the weather and heat permit, wear loose-fitting, long-sleeved clothing.

Keep windows and doors closed or covered with screens to keep mosquitoes out of your home.

Empty standing water at least once a week to prevent mosquitoes from laying eggs.

Repair broken screening of windows, doors, porches and patios.

Before you travel, learn about the health risks and precautions for malaria and other diseases for your destination.

If you plan to travel abroad, check with your health care provider for current recommendations on prescription drugs to prevent malaria.

If you have traveled to an area where malaria transmission is high, and you have fever, chills, headache, body aches, and fatigue, seek immediate medical care and tell your health care provider that you have traveled .
