A recent study published in the journal Clinical Infectious Diseases found that there was an association between healthcare workers’ exposure to high levels of carbon dioxide (CO2) and their risk of being exposed to tuberculosis (TB). Elri Voigt unpacks the study’s findings and asks experts how CO2 monitors work, how well they predict the risk of TB exposure, and in which settings these monitors might be most useful.
Tracing the close contacts of people ill with tuberculosis (TB) and offering them TB preventive therapy is part of South Africa’s strategy to fight TB. A recent analysis found that such an approach of tracing household contacts and providing them with TB preventive treatment is cost-effective and would – by 2025 – cut deaths by 35% among household contacts of all ages and people living with HIV. In light of these new findings, Tiyese Jeranji assesses the state of contact tracing in South Africa’s public healthcare system.
New tuberculosis infection guidelines released ahead of World TB Day are another important step in the right direction for South Africa’s TB response, argues Spotlight editor Marcus Low, while also warning of the substantial implementation challenges that remain.
Tuberculosis (TB) preventive therapy is highly effective in preventing TB disease and death, yet only a few people have access to it. Tiyese Jeranji reports on how Médecins Sans Frontières (MSF) in Khayelitsha is helping TB patients, as well as their contacts, access preventive therapy in the comfort of their homes as part of a new family-centred TB care initiative.
According to new estimates from the World Health Organization around 61 000 people died of TB in South Africa in 2020, an increase of around 5% over 2019. That works out to over 1 100 TB deaths in the country every week. We urgently need a transparent TB recovery plan and we need both President Cyril Ramaphosa and Health Minister Joe Phaahla to invest real political capital in the implementation of the plan, the authors argue.
