In a public health announcement delivered Thursday, Health Minister Michael Joseph of Antigua and Barbuda confirmed that one international traveler has died from imported malaria, marking the country’s first documented fatal case of the mosquito-borne disease linked to recent incoming travel from a high-risk region. Two separate imported malaria cases, both involving male travelers arriving from areas where malaria is endemic, have been identified by national health authorities, prompting immediate activation of heightened disease surveillance and expanded vector control measures across the islands.
According to Minister Joseph, the traveler who ultimately died began experiencing illness almost immediately after entering the country. In rapidly declining health, he sought emergency care at the Sir Lester Bird Medical Centre when his condition became severe. Just five days after arriving in Antigua and Barbuda, the traveler passed away from complications of the infection.
The second confirmed case involves a separate male traveler, also arriving from a malaria-endemic zone, who sought medical care soon after noticing symptoms. This patient was admitted to the hospital for targeted treatment, made a full recovery, and departed the country roughly five days after arriving, Joseph reported.
In his remarks to reporters, the minister emphasized that both infections are definitively classified as imported, meaning they were acquired outside of Antigua and Barbuda before arrival. As of the latest briefing, there is no evidence to suggest the parasite has begun spreading through local mosquito populations, a key point to reassure the public of ongoing low overall risk.
Malaria, a disease caused by the plasmodium parasite, spreads to humans almost exclusively through bites from infected female Anopheles mosquitoes. Common telltale symptoms include high fever, cold chills, intense headaches, muscle aches, generalized weakness, and gastrointestinal distress such as nausea and vomiting. While Anopheles mosquitoes have been previously documented in Antigua and Barbuda, ongoing surveillance data confirms the local population of this vector remains small, keeping the broader community risk at a manageable level.
Immediately after the two cases were confirmed, the country’s public health system launched full response protocols, including comprehensive epidemiological investigations, contact tracing to monitor anyone who may have been exposed, expanded mosquito population tracking, and continuous monitoring of new suspected cases. Investigations confirmed that both travelers were already symptomatic upon arrival or developed symptoms within days of entering the country, which supported the classification of both cases as imported, based on their travel histories and the timing of symptom onset.
The Central Board of Health has ramped up targeted mosquito control operations in all areas linked to the two cases. These measures include thorough environmental inspections, targeted treatment of water sources with larvicides to kill mosquito larvae before they mature, strategic fogging to reduce adult mosquito populations, and ongoing monitoring of local vector numbers to detect any unexpected growth.
Minister Joseph called on local residents to partner with public health authorities in reducing mosquito breeding grounds by taking simple preventive steps: draining any pooled standing water around residential properties, sealing all water storage containers, clearing debris from drains and gutters that can trap water, using EPA-approved mosquito repellents when spending time outdoors, and ensuring window and door screens are intact to keep mosquitoes out of homes. He also urged anyone experiencing fever or flu-like symptoms – especially those who have recently traveled internationally – to reach out to a medical provider for evaluation as soon as possible.
“The Ministry of Health’s surveillance and response systems remain fully activated and positioned to respond to any developments,” Joseph said, noting that national authorities will continue closely monitoring the situation for any changes to the public health risk profile.
