What is the transmission route of tuberculosis

summary

Most of us know that tuberculosis is infectious to a certain extent, but many people are not clear about the specific route of transmission. Recently, I have studied it and learned what the route of transmission of tuberculosis is. Now I'll share it with you.

What is the transmission route of tuberculosis

First, air respiratory tract, which is the main route of infection of tuberculosis. When a patient talks loudly, coughs or sneezes, many droplets with Mycobacterium tuberculosis will be released. If the susceptible inhales the droplets, they can be infected. Tuberculosis patients if the sputum spit on the ground, dry sputum, Mycobacterium tuberculosis and dust mixed together in the air, inhaled by healthy people in the lung can also cause infection.

Second, tuberculosis can be transmitted through food. The tableware used by tuberculosis patients and the leftover food may be contaminated with Mycobacterium tuberculosis. Sharing tableware with tuberculosis patients or eating the rest of the patient's food is easy to get Mycobacterium tuberculosis. Drinking non sterilized milk or dairy products can also infect bovine Mycobacterium tuberculosis. If you don't wash your hands carefully after contacting the patient's used spittoon and other items, you may also be infected.

Third, there is a way of vertical transmission of tuberculosis. During pregnancy, the mother with tuberculosis can enter the fetus through umbilical cord blood. The fetus can also be infected by swallowing or inhaling amniotic fluid containing tuberculosis, thus suffering from congenital tuberculosis.

matters needing attention

There are many ways of transmission of tuberculosis, so once tuberculosis is found, it should be treated in time to avoid infecting others.
