Hello. I am 4 weeks pregnant. My husband tested PCR-positive for COVID-19 on 12.06. My children and I have no symptoms. Right now it's not even possible to get tested — there are no sample tubes available in the city.... I also have blood group 4-negative; abortions are undesirable.... If I also have this virus and it is asymptomatic, does it affect the fetus and what should I do?
