Coahuila health officials report first human myiasis case, warn of wound care

The Health Secretariat of Coahuila confirmed Mexico's first human case of myiasis, a parasitic infestation caused by the Cochliomyia hominivorax fly. The patient, an 84‑year‑old veterinary doctor, developed severe infection after a chest wound went untreated for over three months. He remains stable after hospital care. Authorities activated epidemiological surveillance, performed fumigation around the patient’s home, and found no additional cases.

In parallel, the Secretariat of Health of Michoacán urged residents to take extra precautions during persistent rainfalls, especially vulnerable groups such as children and the elderly. Officials highlighted the risk of water‑borne mosquito breeding and advised preventive measures, including eliminating standing water, using protective clothing, and seeking prompt medical attention for symptoms of illness.

Both state health agencies emphasized the importance of timely wound care and vector control to prevent health complications.
