How long is latent period of child tuberculosis?

summary

Tuberculosis is one of the oldest infectious diseases in human diseases. Human beings have been fighting against it for thousands of years. However, tuberculosis is still prevalent in the world, which poses a serious threat to human health and life. How long is the incubation period of tuberculosis in children? Next, I'd like to share my views with you.

How long is latent period of child tuberculosis?

Tuberculosis will be infected within three months, but not the same, the length of the incubation period depends on the number of infected virus and virulence size, as well as the physical conditions of infected people. If the physical condition of the infected person is not good, the incubation period will be relatively short, and the patient may get sick within a few months. If the physical condition is not good, the incubation period will be relatively long, and the patient will not get sick for a few years, and most of them will not get sick in their whole life.

We generally don't talk about the latent period of tuberculosis in children, but often talk about latent infection of tuberculosis. Latent infection of tuberculosis does not necessarily occur. It means that the human body does not show clinical symptoms after being infected with Mycobacterium tuberculosis, and there is no obvious positive finding in bacteriology or imaging. However, most of these patients have a history of contact with tuberculosis patients, moderate positive PPD skin test or positive T-SPOT.

Latent tuberculosis infection is usually occult, and it is difficult to be found. When such patients show symptoms of cough, expectoration, fatigue and emaciation, they go to the hospital for examination, and then they are found to have progressed to tuberculosis. There is no definite limit for the duration of latent infection of tuberculosis. The incidence of tuberculosis after infection is related to the amount of infected bacteria, virulence and immunity of the infected

matters needing attention

The key to the prevention and control work is to establish and improve anti tuberculosis organizations at all levels. The work of prevention and control institutions (health and anti epidemic station, tuberculosis prevention and Control Institute) includes: investigating the epidemic situation of tuberculosis, formulating prevention and control plan, carrying out appropriate communication education, training prevention and control backbone, evaluating the effect of prevention and control and exchanging experience, etc,
