Human cases of screwworm myiasis (Cochliomyia hominivorax) continue to rise in Honduras as seven new infections were reported this week, according to data by authorities from the Health Surveillance Unit.
This brings the total human cases to 191.
According to Homer Mauricio Mejía Santos, head of the Health Surveillance Unit, the majority of cases are being reported in the Central District, Comayagua, Lempira, and Yoro regions.
The Ministry of Health warned that the insect causing this disease has already been detected in Tegucigalpa and other cities across the country. Mejía Santos stated that the urban population must also step up prevention measures. “The insect is already present in the capital, and extra precautions must be taken, especially regarding the elderly,” he warned.
Honduras battles increase in screwworm myiasis
Mejía Santos confirmed that the death toll remains at three- the deceased include a 78-year-old man and a 77-year-old woman—both residents of the Francisco Morazán department—who suffered complications associated with the infection.
The third fatality was an 85-year-old woman from the Olancho department; she also suffered complications resulting from the myiasis, despite receiving medical attention.

Agricultural authorities report thousands of cases in animals. By May, more than 4,600 infections had been recorded in cattle, pigs, dogs, and other species—a situation that has put both the health and livestock sectors on alert.
The spread of the screwworm has caused concern because Honduras had been declared free of this pest in 1996. However, authorities detected new outbreaks in animals in 2024, and human cases began to be recorded starting in 2025.




Hi: I need help from people who love science! Can data center cooling loops recycle electricity from condensation as MIT's groundbreaking 2013 experiments suggest?
As data centers face an unprecedented energy and cooling crisis driven by AI infrastructure, billions are being spent on managing thermal phase changes—specifically evaporation and condensation.
In my latest work at Decoding Science, I’ve outlined a simple backyard citizen-scientist experiment that suggests we fundamentally misunderstand electron behavior during these phase changes. Standard solid-state models predict a neutral net current during condensation on these surfaces, but geometric manipulation reveals a measurable electrical anomaly.
If this anomaly scales, it means the massive humidity and condensation loops already running inside data center cooling infrastructure could be harnessed to harvest electricity directly from waste heat. Perhaps equally significant is how understanding evaporation will facilitate the cooling process.
I’ve laid out the simple, reproducible experiment to prove this effect. Would you be interested in a brief look at how rethinking electron kinetics during condensation could impact the future of data center efficiency?
