Is Latent tuberculosis Contagious?
Infection and Latent tuberculosis
Latent tuberculosis is not contagious from person to person. While latent tuberculosis is not an active infection, the bacteria may start to multiply and spread.
Transmission of Latent tuberculosis from Person to Person
Latent tuberculosis is considered infectious but is not transmitted from person to person.
Generally, a disease like this is caused by an infectious agent and not spread between people.
Latent tuberculosis, although infectious, is not a genetic disease. It is not caused by a defective or abnormal gene.
