Physical Environmental Conditions and Germ Number in Bedroom of Tuberculosis Patients in Kupang City, East Nusa Tenggara Province

The ability of Mycobacterium tuberculosis as the agent of tuberculosis (TB) to live in the air is generally very dependent on environmental factors, which can cause bacteria to last long in the air and increase the risk of transmission of TB. The research purpose was to analyze the relationship between the physical environment condition and the number of germs in the bedroom of TB patients. This cross-sectional research was conducted in Kupang city, East Nusa Tenggara province, in January–June 2022 with 77 TB patients as samples, whose TB patients' rooms would be observed based on research variables for physical environmental conditions. Data were collected directly by observing and measuring directly from the variables studied and then analyzed using a correlation test and linear regression test to see the relationship between variables and the effect of the physical environmental condition on germ number in the bedroom. The correlation test shows the variables related to the bedroom germ number (p
