Contact history generally appears when asking and writing cases, which mainly refers to the contact between patients and some pathogenic factors. For example, if a patient is suspected to have an infectious disease (such as tuberculosis), he should be asked whether he has a contact history with related diseases (such as tuberculosis), that is, whether he has had contact with tuberculosis patients.

In another case, when a patient is suspected of lead poisoning, he should be asked whether he has a history of lead exposure, or his working environment, or his diet.
