A recent study conducted by the Kenya Medical Research Institute (KEMRI) has shed light on a concerning trend in tuberculosis (TB) cases in Kiambu County. According to the findings, a majority of individuals who tested positive for TB between November 2023 and January this year were men with alcohol use disorders (AUD).
Led by Annfreshia Wangari, a clinical epidemiologist at the Ministry of Health, the study highlights the significant impact of alcohol consumption on TB rates. The researchers discovered that excessive alcohol consumption increases susceptibility to TB infection and complicates treatment efforts.
The research team explains the connection between alcohol and TB through two key factors. Excessive alcohol consumption weakens the immune system, making individuals more susceptible to both new TB infections and the reactivation of latent TB. Secondly, heavy drinkers often frequent social settings like bars, shelters, and prisons, which are known to facilitate the spread of infectious diseases like TB.
The study underscores the importance of implementing targeted interventions to address TB among individuals with alcohol use disorders. In Kiambu County, where high rates of unmarried men with AUD pose a significant challenge, innovative strategies are needed to reach this vulnerable population.
Furthermore, the study highlights the effectiveness of social contact invitation strategies in increasing TB patient yield and enhancing treatment adherence. By educating TB patients about transmission modes and risk factors and encouraging them to bring social contacts for screening, the researchers aim to reduce stigma and improve treatment outcomes.
The Ministry of Health recognizes the importance of proper implementation of such strategies in creating awareness, reducing stigma, and improving TB treatment uptake at the community level. By empowering clients with knowledge and encouraging early diagnosis and treatment, the impact of TB can be mitigated.
