i desperately need answers , my family is infected with covid 19 & only me, my son & husband is stil negative but today my son (10 Months old) is having a very high fever and i think it’s the virus attacking his immune (each of my family member has a fever before getting a positive results) , i’m very worried like what do i have to do? if my baby really positive, what will happen to him? will he be placed at hospital? if yes, can i accompany him even if i’m positive with no symptoms? please help me
