The United States has witnessed an uptick in locally acquired malaria cases, with at least seven reported over the past two months. This marked the first 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 the general public to remain vigilant due to 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 particularly alarming is that none of the patients had traveled outside their respective states before contracting the parasite, raising concerns about the potential for further spread within local communities.
Malaria was declared eliminated as a major national public health problem in the U.S. back in 1951. However, the parasite has managed to resurface annually, with the country recording approximately 2,000 malaria cases each year. The cases primarily involve individuals returning to the country after traveling abroad, according to 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 at the University of Florida’s College of Veterinary Medicine, said via the Sarasota Herald-Tribune that cases of locally acquired malaria are relatively uncommon. The last recorded outbreak of such cases occurred in 2003 when Palm Beach County documented eight instances.
Although transmission within the U.S. is limited, the recent rise in malaria cases serves as a reminder that despite the disease being eradicated in many nations, continued vigilance and adherence to preventive measures are crucial.
