Why is it important?

In this study, the registered cases at an arbitrarily selected chest disease clinic in Dhaka under the National Tuberculosis Control Program (NTP) of Bangladesh was considered. From the study of the sample of 303 cases, it was revealed that women are more likely to be affected by Tuberculosis bacilli at early ages as compared to men in Dhaka. Mann Whitney Median test showed a significant difference between the median age at first infections of male and female (p-value < 0.001). In addition, it is also observed that there is a significant difference (p-value<0.05) between the median age at first infection between people with in-house occupational activities and individuals with outgoing occupational activities where outgoing people are infected by Tuberculosis bacilli at later ages than in-house workers. An exponential regression model shows a significant effect of the variables sex and place of occupational activities on the age at first infection (p-value < 0.05).
