The Ministry of Health and Wellness (MOHW) in Belize has confirmed the first human case of New World Screwworm (NWS) in the country since the parasite’s re-emergence in December 2024.

The patient, a 21-year-old male from Benque Viejo del Carmen Town in the Cayo District, sought treatment at the San Ignacio Community Hospital on August 15. Samples taken in collaboration with the Belize Agricultural Health Authority (BAHA) confirmed the diagnosis. According to health officials, the patient is receiving treatment and is responding well.

The Ministry reminded the public that prevention relies heavily on proper wound care to avoid contact with the NWS fly. While most cases in Belize have been reported in dogs, the parasite can infect all warm-blooded animals, including livestock, wildlife, and pets. Residents are urged to regularly inspect animals under their care and promptly treat any wounds to reduce the risk of transmission.

The New World Screwworm (Cochliomyia hominivorax) is a parasitic fly that lays eggs in open wounds of both humans and animals. The larvae feed on living tissue, causing severe pain, tissue destruction, and—if untreated—potentially life-threatening infections. Human infestation, known as New World Screwworm myiasis, poses a significant public health concern due to the parasite’s ability to spread rapidly.

MOHW, in partnership with BAHA and other agencies, says it will continue surveillance and public education campaigns to help limit further cases.
