China's National Health Commission has made alterations to contents such as COVID-19 etiological and epidemiological features, as well as epidemic monitoring and handling.

For the convenience of epidemiological investigations, the latest version gave specific criteria for imported cases, new infections linked to imported cases, and close contacts of close contacts, among other terms.

As per the guidelines, the imported cases of COVID-19 will now include imported secondary cases, as well as close contacts of close contacts. It will investigate the source of infection, the scope of contamination, transmission characteristics and transmission chain. The latest guidelines have also revised the requirements for centralised isolation and home medical observation.

According to the guidelines, passengers entering the Chinese mainland should spend 7 days in isolation centers after taking a COVID-19 test at ports of entry, for medical observation. They must take another test before completing quarantine, it added.

The guidelines further went on to add that if the test result is negative, passengers from outside the Chinese mainland can isolate themselves at home for another 7 days before they are free to travel.
