In some Canadian Indigenous groups, genetic susceptibility may play a role.<ref name=":0" /> Socioeconomic status (SES) strongly affects TB risk. People of low SES are both more likely to contract TB and to be more severely affected by the disease. Those with low SES are more likely to be affected by risk factors for developing TB (e.g., malnutrition, indoor air pollution, HIV co-infection, etc.), and are additionally more likely to be exposed to crowded and poorly ventilated spaces. Inadequate healthcare also means that people with active disease who facilitate spread are not diagnosed and treated promptly; sick people thus remain in the infectious state and (continue to) spread the infection.<ref name=":0" /> Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
