Objective:
To determine the incidence of relapse in patients with lung tuberculosis and its associated risk factors.
Methods:
A follow up study was conducted with 237 patients who were cured after receiving treatment in rural medical facilities from the State of Chiapas.
Results:
The global incidence of relapse was 1.04 cases per 100 month/person. The risk factors for relapse were lack of knowledge about treatment (OR = 2.28; 95% CI = 1.06-4.89); drug adverse effects (OR = 2.78; 95% CI = 1.31-5.90), waiting time for more than 15 minutes to receive medical care (OR = 3.07; 95% CI = 1.06-12.94) and lack of medical supervision (OR = 4.77; 95% CI = 1.30-17.41).
Conclusions:
Most of the risk factors for relapse are susceptible to modification and are related with the quality of medical care provided to lung tuberculosis patients.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
