Thousands of university freshmen have tested positive for liver fluke infection in Maha Sarakham, prompting wide-ranging inspections targeting the use of undercooked fermented fish at somtam shops in the northeastern province.
The initial results were obtained using urinary antigen test kits (UATs), a faster testing method developed in recent years, Public Health Minister Pattana Promphat said on Tuesday. Stool examinations were still required to confirm the presence of the infection (opisthorchiasis).
