CHAIYAPHUM: Lab test results showed norovirus and E.Coli bacteria caused the illness that sent more than 300 students and teachers from four schools in this northeastern province to hospitals this week with diarrhoea and vomiting.
The tests were done on samples taken from students and teachers after they became ill on Tuesday, said Dr Wachira Botphiboon, chief of the provincial public health office. E.Coli bacteria could be found in both food and ice cubes, he said.
