“…Several studies have corroborated our findings, indicating that the level of schooling may affect the level of knowledge and the ability to seek compatible living conditions with a good level of health [ 18 – 21 ]. Urban agglomeration has been identified as a predictor of both the occurrence of tuberculosis and the undesired outcomes of its treatment, including neglect [ 22 , 23 ]. Life expectancy at birth was inversely associated with the occurrence of treatment non-adherence.…”

Success in tuberculosis control depends on the implementation of steps that reduce social inequities, allowing the diagnosis and effective treatment of the disease. Little is known about the conditions affecting antituberculosis treatment non-adherence in areas of great social and economic heterogeneity, such as the municipality of Rio de Janeiro. This study aimed to describe and identify the social determinants of antituberculosis treatment non-adherence in the municipality of Rio de Janeiro between 2008 and 2012. An ecological study was conducted with the districts of Rio de Janeiro as the units of analysis. Analyzes using Poisson regression models allowed us to identify the association between dropout from antituberculosis treatment and the human development index and social development index. The final model showed that economic conditions, infrastructure, and the tuberculosis control quality of surveillance were associated with treatment non-adherence. This study demonstrated that the scenarios of socio-environmental precariousness found in the districts of Rio de Janeiro were able to identify populations with an increased risk of default treatment from antituberculosis.

“…For raw milk consumption, two population‐based cross‐sectional studies, one in Tanzania and one in Ethiopia, found no association (Mfinanga et al, ; Tschopp et al, ). However, three case‐control studies in Ethiopia and one in Nigeria found strong significant associations, with the highest OR being 8.8 (95% CI 2.6, 29.81) (Berg et al, ; Fetene et al, ; Mengistu et al, ; Waziri et al, ).…”

“…Several prior studies have investigated the association between human TB and cattle-associated risk factors, including bTB positivity and raw milk consumption, without distinguishing between members of the M. tuberculosis complex or excluding pulmonary TB cases (Berg et al, 2015;Fetene, Kebede, & Alem, 2011;Mengistu, Enquselassi, Aseffa, & Beyen, 2015;Mfinanga et al, 2003;Tschopp, Schelling, Hattendorf, Aseffa, & Zinsstag, 2009;Waziri et al, 2014). One study did not include any TB-free controls, three used a hospital-based population and thus potentially induced selection bias, and three relied on self-reported TB status and thus potentially induced information bias (Berg et al, 2015;Fetene et al, 2011;Mengistu et al, 2015;Mfinanga et al, 2003;Tschopp et al, 2009;Waziri et al, 2014). Furthermore, the findings of these studies do not reach a consensus; among those that evaluated bTB positivity in the cattle herd as a risk factor, odds ratios for TB positivity in humans ranged from a non-statistically significant 1.2 (95% confidence interval 0.6, 2.4) to a statistically significant 8.32 (95% CI 2.82, 24.6) (Fetene et al, 2011;Mengistu et al, 2015;Tschopp et al, 2009).…”

Tuberculosis (TB) is a leading infectious cause of human death worldwide. In cattle, TB infection results in productivity losses, trade barriers and zoonotic transmission via milk, meat or direct contact. We conducted a cross‐sectional study in rural communities in Uganda between 2014 and 2016 to evaluate the association between tuberculosis skin test (TST) positivity in humans and cattle‐associated risk factors: household herd positivity and raw milk consumption. Human and cattle TSTs were performed in communities followed by a survey of household practices. TST data were available on 493 humans, 184 (37.3%) with positive results, and 1,441 cattle, 50 (3.5%) with positive results. We fit separate log binomial generalized estimating equation models for the herd positivity‐human TST positivity association, stratified on sex; and for the raw milk consumption‐human TST positivity association, stratified on frequency of milk consumption. Having at least one TST‐positive bovid in the household's herd was significantly associated with lower risk of TB among men (prevalence ratio [PR] 0.66, 95% CI 0.49, 0.87) but was not significantly associated with TB among women (PR 1.21, 95% CI 0.76, 1.95). This apparent protective effect was contrary to our a priori hypothesis of higher exposure effect among men, the primary caretakers of cattle. This finding may be the result of residual confounding by socioeconomic status; wealthier individuals may be less likely to be TB positive, but more likely to have TST‐positive herds by virtue of larger herd sizes, ability to purchase new and possibly infected stock, and propensity to keep more TB‐susceptible European breeds. For raw milk consumption, effect estimates were close to one and not statistically significant. Thus, in settings where bovine TB prevalence is low, such as Uganda, cattle‐associated zoonotic transmission may be rare, and cattle‐associated risk factors may not be important drivers of human TB burden.

“…Recent studies have however revealed that the prevalence of M. tuberculosis in African and Asian cattle ranges between 4.7% -30.8% in countries with high human TB incidences [37]. The isolation of M. bovis and M. tuberculosis in slaughtered cattle confirms that there is zoonotic tuberculosis in the studied areas, which should be considered a public health concern especially among the pastoral communities that have strong attachments to their cattle for cultural, social and economic welfare [38].…”

“…The proportion of M. africanum is low compared to previous reported studies done in some parts of Nigeria; Cadmus et al [11] reported 13% in Southern Nigeria, while Waziri et al [38] reported 10.8% in pulmonary patients in Zaria, Kaduna State. The reasons for the low prevalence in our study has not been deduced, but finding M. africanum which has been isolated in milk of pastoral cattle in Nigeria may suggests possible zoonotic transmission of this organism which was previously thought to be limited to humans.…”
