Environmental Risk Factors of TB Infection in Northwest Nigeria
Journal Title: Saudi Journal of Humanities and Social Sciences - Year 2017, Vol 2, Issue 10
Abstract
Within the last two decades, tuberculosis (TB) has shown an unprecedented and rather unexpected re-emergence despite achievements in immunization, provision of heath care facilities, discovery of drugs and better understanding of the disease. The Northwest Region of Nigeria is one of those corridors through which the transmission of the disease could be enhanced due to seasonal migration of pastoralists serving as carriers of the disease, going by their mobile lifestyle. This paper tried to examine the prevalence of the disease in this area, with the aim of identifying the environmental risk factors associated with it, among others. Data were collected using a structured questionnaire on 461 patients receiving treatment as sample across the DOTS centres along Fulani route of seasonal migration. Analyses were carried out using descriptive statistics and the logistic regression while significance test was done using ANOVA. Results indicated that ‘ever been diagnosed of lung and heart-related diseases’ had the highest contribution in the model (B=4.943), followed by ‘ever stayed with a TB patient’ (B=2.213) and then ‘family member ever been infected with TB’ (B=1.411). However, the ANOVA test on number of persons sleeping in a room indicated no statistically significant difference in the means of the groups, F (15, 89) = 1.117; p = 0.354. It was concluded that contact with the index and overcrowding play a role in the prevalence of TB in the study area and therefore recommend further studies on individual risk factors so as to guide disease surveillance and control.
