Maryland authorities disclosed a new case of locally acquired malaria on Aug. 19, making the state the third in the country to report a case in recent months.
The person tested positive for malaria despite not recently traveling outside the United States or to a state that has reported malaria cases, according to the Maryland Department of Health.
The person was hospitalized and “is now recovering,” officials said in a statement. The person lives in Maryland.
The agency didn’t disclose the age or sex of the person nor more specific information about where he or she lives.
“To protect patient confidentiality, we are not sharing any further patient information,” a Maryland Department of Health spokesperson told The Epoch Times via email.
The agency is also declining to say whether there are any suspected additional cases.
“That is the only confirmed case,” the spokesperson said.
Texas and Florida have recently reported locally acquired malaria cases, which differ from cases in which people contract malaria while traveling overseas.
Before the new cases, no locally acquired cases had been detected in the United States since 2003.
Symptoms
More than 2,000 cases of malaria are reported in the United States each year, according to the U.S. Centers for Disease Control and Prevention. About 200 of those are in Maryland.Malaria is often caused when people are bitten by mosquitoes that have been infected by certain kinds of parasites.
Malaria can also spread through procedures such as organ transplants because the parasite is found in an infected person’s red blood cells.
Symptoms usually start seven to 30 days after becoming infected. Symptoms include fever, sweating, chills, headache, and nausea.
Testing can confirm a malaria case.
No malaria vaccine is available, but some drugs are aimed at preventing infection. Other drugs help treat malaria once it’s contracted.
Recommendations
In addition to antimalarial drugs, people can increase their chances to avoid malaria by wearing insect repellent, wearing long-sleeved clothing, and keeping windows and doors closed.Officials also recommend removing standing water in yards at least once per week, which will prevent mosquitoes from laying eggs.
Earlier Cases
Earlier in 2023, cases cropped up in both Texas and Florida.The Texas resident who tested positive lives in Cameron County, according to the Texas Department of State Health Services.
The case was the first locally acquired one in the state since 1994.
In Florida, all six of the cases were detected in Sarasota County, about halfway between Tampa and Fort Meyers.
All of the patients have since recovered, officials said.
There were no signs that the cases in the two states were related, according to the CDC.
“The key remains early detection and treatment of imported human cases to minimize the risk of onward transmission,” the agency stated.
The CDC has stated that there was a possibility that the number of imported malaria cases would rise over the summer, in part because more people were traveling internationally than in recent years.
