TB is the leading cause of death in South Africa and drug-resistant TB continues to be a problem, particularly in the province of Kwazulu Natal. Curbing hospital-acquired infections such as drug-resistant TB may be one aspect of a multi-pronged strategy aimed at controlling the spread of this infectious killer. I blogged about this topic on The Norwalk Patch and am reposting the information here:
While there has been a 45% decrease in tuberculosis death rates since 1990, the growing crisis of drug-resistant tubercle bacilli (480,000 new cases of multi-drug resistant TB in 2013), high mortality rates (1.5 million deaths out of 9 million diagnosed TB cases in 2013), and ongoing HIV/TB co-infected cases (360,000 in 2013) persist across the globe. The post-2015 End-TB strategy from the World Health Organization involves three tiers i.e., integrated, patient-centered care and prevention, bold policies and supportive systems, and intensified research and innovation.
Appropriate disinfection and decontamination of hospitals, clinics, and other medical centers to reduce the prevalence of this airborne pathogen will be an important aspect of any integrated patient-centered care and prevention strategy. The merits and perils of automated systems such as hydrogen peroxide vapor and ultraviolet light disinfection systems to reduce the impact of hospital-acquired infections are discussed in Automated Technologies for Patient Room Disinfection and Decontamination of Biosafety Level 4 Infectious Agents, Including Ebola Virus.
