Adults can not only carry the HFMD virus, they can also contract it. HFMD is not just a disease that can be acquired by young children; adults who get HFMD can be infected for a longer period of time than children. Therefore, if adults have HFMD, they should be isolated from children because saliva from HFMD patients can be spread in the air and children can easily be infected. Adults with HFMD who go to the bathroom without washing their hands and hold the child directly can also infect the child through contact infection because feces can also contain pathogenic bacteria. In addition, if leftover food from adults is eaten by children, they can also be infected with HFMD. Therefore, it is possible for adults to carry the HFMD virus, and care should be taken to maintain good hygiene habits with the child.
