Medical institutions need to re-configure the obstetric wards in time to respond to the treatment of pregnant women with COVlD-19.

(1) For general obstetric wards, efforts should be made to ensure that the beds are at least one meter apart and separated by screens or curtains. Use of central air conditioner should be suspended, and the rooms be well ventilated and kept at a suitable temperature.

(2) lsolation obstetric wards should be constructed with clear division of various areas as follows: two different access channels will be used for the access of health workers and patients; the three zones of different contamination levels, namely clean areas, semicontaminated areas, and contaminated areas; two buffer areas, the first is between the clean area and the semicontaminated area, and the second buffer between the semi-contaminated area and the contaminated area.

(3) The ward, delivery room and operating room should be located in the negative-pressure isolation area.The clean area, semi-contaminated area and contaminated area should be clearly set up in the ward, which will correspond to different levels of person protection for health workers in the areas. When the patients are transferred,specific transfer channel should be set up and equipped with sound disinfection and protection protocol. The overview of the isolation obstetric ward setup is shown in Figure 1.
