Occupational transmission of bloodborne diseases to healthcare workers in developing countries: meeting the challenges.

Healthcare workers have increased chance of acquiring bloodborne pathogens through occupational exposure in developing countries due to a combination of increased risk and fewer safety precautions. As loss of workers can seriously undermine developing health systems, it is important that risks are minimised. A literature search was conducted to investigate the risks of transmission of three pathogens: human immunodeficiency virus, hepatitis B and hepatitis C viruses; and to identify factors that influenced the risk with reference to developing countries. There are many difficulties faced by developing countries in minimising the risk of occupational exposure. Efforts have been made to address the problems both on international and national levels. It is imperative that all healthcare workers are protected in order to prevent the loss of such a crucial component of developing healthcare systems.
