Asymptomatic carrier

    An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has contracted an infectious disease, but who displays no symptoms. Although unaffected by the disease themselves, carriers can transmit it to others. In humans, HIV goes through a long latency period, during which the host is asymptomatic. Many carriers are infected with persistent viruses such as EBV and Cytomegalovirus that only rarely progress to a disease state.
