While UVA and UVB have their own problems such as the possible eventual emergence of skin cancer, UVC is highly dangerous to both the eyes and the skin, but studies have shown that humans are protected by the solar radiation of the ozone layer. 5 Sunlight as it was long reported, provided irradiation at ground level longer wavelength UVA and UVB, which are used by holidaymakers for obtaining a suntan. In all these patients, it was UVC, which was used. The first report of the use of ultraviolet radiation was in 1930, this was proved effective in sanitizing air and killing harmful bacteria and microbes, including TB. Research has shown that in developing countries such as South Africa where tagging and tracing of cases is difficult, UV sterilization and other environmental control measures can successfully be used to protect the spread of TB. 4Įnvironmental control measures of ultraviolet radiation can only be enhanced by other factors such as active detection, prompt treatment and tracking of cases. UV lamps are cost efficient, accessible and, installation friendly and therefore they are strongly recommended by various health government agencies worldwide. Ultraviolet radiation is one of the commonest environmental control measures that can be used to kill infectious microorganisms such as TB.

3 In these instances, the primary objective is to prevent the spread of TB by protecting susceptible people from inhaling airborne particles generated by infectious individuals using environmental control measures. 2 To control the spread of TB infection, some facilities are implementing other control measures such as environmental measures (filtration, ventilation, UV radiation) to halt the rate and spread of TB infection. The World Health Organization (WHO) has put a mandate, especially in developing countries such as South Africa, to improve infection control in hospitals, as facilities risked becoming the breeding ground for XDR-TB if patients and staff are not adequately protected from those infected. 1 This has placed a new emphasis on preventing the spread of TB from patient to susceptible individuals. The new problem which has hit the world, including South Africa, is the emergence of multidrug resistance (MDR) or extensively drug-resistant (XDR) forms of TB. TB has experienced a resurgence in recent years and is often a hallmark of HIV/AIDS, causing those infected not to seek medical attention because of social stigma. So, the longer the susceptible or uninfected person share space or air infected with these bacilli, the greater the chance of infection. People who are infected, or are on multidrug resistance (MDR) or extensively drug-resistant (XDR) treatment, to the next person or to the surrounding area or room, cough up this bacterium on air. TB is transmitted from person to person by tiny droplet nuclei containing the acidfast bacilli called Mycobacterium tuberculosis. Environmental measures have gained much more interest in the prevention and control of TB transmission. It is a serious public health threat in developing countries such as South Africa, especially among the destitute, groups of the migrants, inmates in correctional services inmates and people infected with the human immunodeficiency virus (HIV). Tuberculosis (TB) remains one of the leading infectious diseases worldwide, despite the efforts to identify and treat infected patients.
