Preventing Transmission of Mycobacterium tuberculosis – a Refocused Approach

• Description:
  Traditional tuberculosis (TB) infection control focuses on known patients with tuberculosis already on therapy, whereas most transmission is from patients with unsuspected TB or unsuspected drug resistance, not on effective therapy. For high-burden settings, a refocused, intensified, administrative control strategy, FAST (Find cases Actively, Separate temporarily, and Treat effectively based on molecular diagnostics), attempts to shorten the time from entry to a health care facility and the start of effective treatment. For low-burden settings, unsuspected TB also poses the greatest transmission risk, but this is better addressed by increased awareness through education. Because not every infectious case will be detected and promptly treated, air disinfection is important in high-risk settings. Environmental controls such as ventilation and germicidal air disinfection reduce risk. Increasing use of air conditioning in warming climates require air supplemental disinfection as windows are closed. Germicidal ultraviolet air disinfection is underused, but after natural ventilation, it is the most cost-effective and sustainable technology. [Description provided by NIOSH]
