The last of the students still staying at the private all-boys boarding school in Bangkok’s Dusit district were taken home early Tuesday afternoon.
Deputy director Piyachanok Limpabhand said no classes had been held since Monday and the school would be closed for seven days in all.
He said most of the infected students were in Grades 4 through 7 and Grade 11.
Piyachanok said the school and dormitory had been thoroughly cleaned and sprayed with disinfectant.
