The private primary school in Shanghai where 45 students were sickened and sent to the hospital for treatment after lunch on Friday said many of the students have recovered.
“None of the students are in critical condition,” according to the director of student affairs at Shanghai Tongyuan Experimental Primary School, who only gave her surname, Zhang.
“Some are still suffering minor symptoms, such as stomach cramps and nausea. The district CDC suggested the students not return to school until 72 hours after the symptoms have fully disappeared.”
Officials at the center for disease control and prevention in the Jing’an district, where the school is located, took test samples from 13 patients randomly on Saturday. Ten tested positive for norovirus, a common cause of acute gastrointestinal illness.
