America has witnessed an uptick in locally acquired malaria cases, with at the very least seven reported over the past two months. This marked the primary instance of local transmission of the disease in 20 years.

Last month, the Centers for Disease Control and Prevention (CDC) issued a public health alert, urging doctors, public health authorities and most of the people to stay vigilant because of the concerning risk of malaria.

Of the seven reported cases, six were identified in Sarasota County, Florida, while the remaining case was identified in Cameron County, Texas. What is especially alarming is that not one of the patients had traveled outside their respective states before contracting the parasite, raising concerns concerning the potential for further spread inside local communities.

Malaria was declared eliminated as a serious national public health problem within the U.S. back in 1951. Nonetheless, the parasite has managed to resurface annually, with the country recording roughly 2,000 malaria cases annually. The cases primarily involve individuals returning to the country after traveling abroad, based on USA Today.

In 2021, Florida and Texas collectively reported 156 cases of malaria, all attributed to individuals who had recently traveled internationally.

Rhoel Dinglasan, a professor of infectious diseases on the University of Florida’s College of Veterinary Medicine, said via the Sarasota Herald-Tribune that cases of locally acquired malaria are relatively unusual. The last recorded outbreak of such cases occurred in 2003 when Palm Beach County documented eight instances.

Although transmission inside the U.S. is restricted, the recent rise in malaria cases serves as a reminder that despite the disease being eradicated in many countries, continued vigilance and adherence to preventive measures are crucial.

Malaria is a disease spread through the bite of infected female mosquitoes from the genus Anopheles. The symptoms of malaria, corresponding to chills, fever, headache, nausea, body aches and diarrhea, can often be mistaken for those of the flu, common cold, and even COVID-19.

Essentially the most common signs of malaria, including fever, chills, headaches, muscle aches, and fatigue, typically manifest inside seven to 30 days after infection. When left untreated, the disease can progress to more severe symptoms, corresponding to impaired consciousness, difficulty respiratory, convulsions, abnormal bleeding and even death.

The CDC recommends using “mosquito avoidance measures” when going outdoors. Using EPA-approved mosquito repellent on each the skin and clothing, wearing long-sleeved shirts and pants, staying in well-screened areas and utilizing insecticide-treated bed nets while camping are a number of the suggested measures against malaria.

Travelers, especially those heading to sub-Saharan Africa, the Indian subcontinent, Southeast Asia, or tropical South and Central America, are advised to seek the advice of with healthcare professionals regarding vaccines and prescription antimalarial medications for disease prevention.
