Can a child get chickenpox and pass it on to adults?

Chickenpox is highly contagious. If an adult touches a child who has chickenpox and has not had chickenpox, he may be infected. Because chickenpox can acquire long-lasting immunity, the chance of secondary infection is relatively rare. chickenpox patients are the only source of infection. The virus can be present in the patient's body fluids, such as the upper digestive tract and herpes fluid. It can be transmitted to others through respiratory droplets and direct contact. 1-2 days before the onset of chickenpox until the rash is completely scab, are infectious, as long as the susceptible population contact, whether adults or children, may be infected. Therefore, once a patient at home got chickenpox, must do a good job isolation, until the patient all scab so far, pay attention to the ventilation of the room.
