Why are all the confirmed patients in Beijing infected in public toilets instead of going to epidemic areas?

The confirmed patients in Beijing did not go to the epidemic area, which was caused by the third-hand infection of the newly developed epidemic. On June 25 and June 20, two of the confirmed cases were stall owners of the food city on the second floor of Tiankelong Supermarket. They are a couple and have no new contact history. The personnel of Beijing Haidian Sixth Dispatch launched an emergency investigation and finally locked the address of No.70 Yongding Road. It has appeared in the activity place where confirmed cases have been reported four times.

The confirmed patient said that he had used the public toilet in No.70 Yongding Road Hospital on June 12. According to experts' inference, the sampling result of public toilets in No.70 Yongding Road Hospital is positive, so the patient may be infected with COVID-19 virus because he has been to public toilets.
