summary

In the face of leprosy infection, many people have doubts, leprosy infection is direct contact infection or indirect contact infection? Can leprosy patients be infected? I believe that all these questions are our doubts. Experts say that leprosy is mainly transmitted through direct contact and indirect contact. Do you want to know how leprosy is transmitted? The following experts will give you a detailed introduction.

Is leprosy hereditary

First: direct contact infection: it is the direct contact between healthy people and patients with infectious leprosy. The infection is caused by the damage of skin or mucous membrane containing leprosy bacilli and the contact of damaged skin or mucous membrane of healthy people. This infection is most common in family members who are in close contact with patients. Although the close degree of contact is related to the incidence of infection, it does not rule out the possibility of occasional contact and infection.

Second: indirect contact infection: it is the infection of healthy people and patients with infectious leprosy through certain media. For example, contact with clothes, bedding, handkerchief, tableware, etc. used by infectious patients. The possibility of indirect contact infection is smaller than that of direct contact infection, but it can not be ignored.

Third: other ways of infection: leprosy bacteria, whether through the skin, respiratory tract, digestive tract, may invade the human body and cause infection. Recently, some people emphasize the way of respiratory tract infection. They think that nasal mucosa is the main way of leprosy bacteria excretion. The leprosy bacteria in nasal secretions can still survive for a considerable period of time in vitro. The dust or droplets carrying the bacteria can enter the respiratory tract of healthy people and cause infection.
