Pang Xinghuo, deputy director of the Beijing Centers for Disease Control and Prevention, introduced a special case on 16 February:
The confirmed patient reunion with his family to celebrate the Chinese New Year. Some of his relatives have "cold" symptoms but nobody care about it not along wear mask.
After the holiday, he went back to Beijing and went to work normally. Later he heard that the relative who has cold symptom was confirmed with novel coronavirus (COVID-19). At this time, he went to hospital to check and found out he was infected.
But because this patient didn't quarantine for 14 days after he went back to Beijing, all of his colleagues were sent to quarantine as close contacts. And one of his colleague has already infected. After the incident, the patient recalled that the colleague had queued to pour the plate after lunch in the cafeteria and neither of them was wearing a mask at the time.
This case shows three facts:
First, returnees from other places must be isolated at home for 14 days before returning to work.
Second, the canteens of collective units should try to implement peak shift meals, increase the distance between tables.
Third, it is best to keep a distance of more than 1 meter when contacting others, please don't forget to wear a mask!
