The retention of the fetus in a pregnant woman infected with the new coronavirus needs to be determined by the growth and development of the fetus, and it is not possible to make a uniform decision. Pregnant women infected with Neocollins need to take proper pregnancy tests. At present, there is no accurate clinical data to prove that the mode of transmission of Neocollins includes mother-to-child transmission, and no infected person has yet been found to give birth to a neonate carrying the Neocollins virus. In addition, the antiviral drugs used in the treatment of neo-coronavirus infection have little effect on the growth and development of the fetus. Therefore, the decision to infect a pregnant woman with Neocollins also depends on the growth and development of the fetus as well as the physical condition of the pregnant woman. It is important to note that pregnant women should follow the doctor’s instructions to have proper pregnancy checkups and closely monitor the growth and development of the fetus after infection. If there is any abnormality in the fetus or the mother, she should receive timely treatment, and if necessary, the pregnancy should be terminated.
