2. People entering Zhengzhou from the middle and high-risk areas in China: it needs to be quarantined for 14 days (during which nucleic acid test is conducted twice and serum test is conducted 1 time). For those who arrive in Zhengzhou within 0/4 days before the horizontal modulation risk is medium and high, continue to implement the measures of "home medical observation until leaving the place/0/4 days after kloc, and carry out nucleic acid detection (serum antibody detection if necessary)".
