14 days. Is it necessary to change hotels after seven days?

No need. However, according to the local epidemic prevention policy, if it is clearly stipulated in the local epidemic prevention policy to change hotels after seven days, of course, it must be arranged according to the local epidemic prevention policy. If it is not clear, it is unnecessary.

Moreover, changing hotels will increase unnecessary risks and cause panic among hotel guests. As long as there are no confirmed or close contacts in the hotel, you should not arrange to change hotels. If you stay in that hotel and have close contacts, you will arrange for the rest of you to do nucleic acid separation. If you are not infected or diagnosed, you will arrange a safe place for security personnel to observe.

If it weren't for being isolated in the hotel because of the epidemic, stay as long as you want, and change if you want.
