Health officials in North Macedonia have declared an epidemic in the Gostivar municipality following a significant increase in gastroenteritis cases, with concerns centering on the local water supply. Since early last week, more than 1,500 people have sought treatment at hospitals, including facilities in Gostivar, about 50 kilometers southwest of the capital, Skopje.

Authorities have recommended residents avoid using the city’s tap water as investigations continue. Epidemiologist Zorica Zafirovska of the Tetovo Public Health Centre confirmed the epidemic declaration and said experts were conducting tests on the water supply to identify the source of the outbreak.

While a definitive cause had not been confirmed as of yesterday, police opened an investigation into the surge in illnesses. Officials suspect that wastewater contamination may have occurred, potentially involving the local water company unintentionally or otherwise introducing sewage into the drinking water system. The Ministry of Interior stated it is working to fully clarify the situation and noted that polluting drinking water could be subject to criminal charges.

The outbreak represents a significant public health concern in the region, prompting ongoing monitoring and preventive advisories to reduce further exposure. Authorities are urging residents to follow guidance until the water supply is declared safe.
