My yaya is positive on Hepa B. Her serology result is Reactive on HBs-Ag, Anti-Hbe, Anti-HBc G and Anti-Hbc M. She was given essentiale forte and zeppix as her medicines. My 2 kids, 3 & 1 yr old have already hepa B3 vaccine. I pity my yaya coz if I let her go, she has no way of buying her medicines so I intend to keep her. What could be the implications to my children and of course to other members of the house. For prevention, she uses face masks and she has own utensils. Is it ok if she stays in the house and take care of the kids? Is it ok if she carries my children. Please give me advise. Is hepa B very contagious that the person has it should be avoided or isolated?
