New World Screwworm Hits Belize’s Howler Monkeys

Three howler monkeys have fallen victim to New World Screwworm (NWS) infestations since July, according to the Belize Wildlife & Referral Clinic (BWRC). Two did not survive, while one, named Georgie, remains in recovery.

BWRC described the cases as “heartbreaking”, noting that NWS is a flesh‑eating parasite whose flies lay eggs in even the smallest wounds. The larvae consume living tissue, often leading to severe injury or death if untreated.

While the parasite can affect livestock, pets, and even humans, BWRC says monkeys are among the latest casualties. In Belize, most reported cases involve livestock like cattle. 

Belize confirmed its first human case of New World Screwworm in August, involving a 21-year-old man from Benque. Within days, a second case was reported in a 60-year-old man from Camalote Village, who was being treated for a leg wound infected with the parasite.

Authorities urge the public to act quickly if they notice warning signs such as open wounds, foul odour or discharge, visible maggots, or animals persistently licking or scratching an area. Suspected cases should be reported immediately to the Belize Agricultural Health Authority (BAHA) at 824‑4872 or WhatsApp (501) 670‑7003, and animals should be taken to a veterinarian without delay.
