Hello Isna, thank you for the question for HealthReplies.com

Latent tuberculosis is a condition in which a person is infected with tuberculosis, but does not show any symptoms and does not have the risk of transmitting the infection to other people. This condition can occur when the person's immune system is strong enough to prevent tuberculosis bacteria from developing in the body. When the person's immune system is weakened for one reason or another, this latent infection can turn into an acute active infection.


Basically, people with latent tuberculosis have tuberculosis infection in their body, and have a risk of developing acute infections in the future. Therefore, this condition must still be treated with OAT. However, the OAT regimen given is different from the OAT given for acute tuberculosis. Treatment can be administered with isoniazid alone, rifampin alone, or a combination of Isoniazid and Rifapentine. The choice of drug and the length of treatment must be adjusted to the condition of each patient.


We recommend that you ask your friend to consult again with the doctor who treated him to get further therapy for tuberculosis.

So much information from me, hopefully it will be enough to answer
