United States: The Costa Rican Ministry of Health announced on Thursday a second fatality attributed to an infestation caused by the screwworm, a larval stage of a fly that infests wounds or mucous membranes of warm-blooded creatures.

To date, health authorities have identified 11 instances of myiasis within the Central American nation. The most recent fatality involved a patient suffering from an oral lesion where larvae were found, as stated by the Minister of Health, Mary Munive, according to ticotimes.net.

On June 19, the country recorded its first human fatality due to this parasitic affliction, engendered by the larvae of the Cochliomyia hominivorax fly.

Human symptoms, as outlined by the Ministry of Health, may encompass pain, severe pruritus, skin erythema, nodules, exuding wounds, and a painful skin protuberance.

The screwworm primarily targets livestock such as cattle, sheep, and goats, yet any warm-blooded animal remains vulnerable, according to the National Animal Health Service, as mentioned by ticotimes.net.

The agency notes that Costa Rica had declared itself free of the disease in 2000. The condition was initially identified in 1858 in Guyana and persists in northern South America, Central America, the United States, and several Caribbean islands.
