The transmission route of tuberculosis

summary

The incidence rate of tuberculosis in everyday life is not low, and it also brings great harm to many families. So it is necessary to understand the transmission route of tuberculosis. Let's look at the transmission ways of tuberculosis.

The transmission route of tuberculosis

1、 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.

2、 Food infection. Tuberculosis patients with tableware, 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.

3、 Vertical transmission. During pregnancy, the mother with tuberculosis can enter the fetus through umbilical cord blood, and the fetus can also be infected by swallowing or inhaling amniotic fluid containing tuberculosis, thus suffering from congenital tuberculosis.

matters needing attention

In addition to the above ways of infection, Mycobacterium tuberculosis can also be directly infected by the skin or mucosal wound. As Mycobacterium tuberculosis can not penetrate the skin, this mode of infection is relatively rare, but it should also be noted.
