Z20: Contact with and exposure to communicable diseases

Z20.1: Contact with and exposure to tuberculosis

Having contact with specific pathogens does not necessarily mean that you will get sick. Whether you get sick and which symptoms you develop depends on several factors. Among these for instance are how long you had contact with the pathogens or how many pathogens you were exposed to. Another factor is how well your own immune system works.

Tuberculosis is also abbreviated to TB. Tuberculosis is caused by certain bacteria. The bacteria are transmitted through coughing and sneezing, for example. The bacteria can remain undetected in the body for a very long time. But they can also cause severe inflammations. The bacteria trigger symptoms when the body’s defense system is weakened. For example, tuberculosis may cause fever, coughing and a feeling of weakness. It is also possible to lose weight and feel very tired.
