Question: Are pregnant and lying in women more susceptible to COVID-19 infection than the general population? How to protect? Qiao Jie: In terms of the overall population performance, the infection rate of Omicron in pregnant and lying in women is close to that of the general population, and the types of symptoms are similar to that of the general population, such as dry throat, cough, runny nose, body aches, fever, etc. In general, compared with the general population, the infection did not bring more impact on the health of pregnant women.

Wang Quan: Autumn and winter are the high incidence seasons for children's respiratory diseases. Fever and cough are common symptoms of children's respiratory diseases. There are many pathogens causing fever and cough symptoms, mainly including influenza virus, some bacteria and mycoplasma pneumoniae. If the child's mental state is stable after illness, the parents can do symptomatic treatment and observe the condition. If the fever lasts for more than three days, high fever continues, cough or vomit frequently, or even mass, frequent diarrhea, pus and blood stool, decreased urine volume, rapid breathing, dyspnea, consciousness disorder, etc. occur, the parents should take the children to the hospital in time. During their stay in the hospital, parents should protect themselves and their children, wear masks and keep hands clean.

Wang Quan: It is OK to prepare some antipyretic drugs suitable for children at home. It is not recommended to store too many drugs at home. Please follow the doctor's advice and carefully read the drug instructions when taking medicine for your child. In order to ensure safety, parents should not give drugs only based on experience. When children live at home, they should keep regular work and rest, get enough sleep, eat reasonable meals, balance nutrition, strengthen exercise, and eat more fruits and vegetables. The winter weather in the north is dry, so parents should drink more water for their children, strengthen parent-child communication, and keep happy. (Liu Xinshe)
