The rapid increase of bacteria serves to
worsen the problem as treatment of infections caused by these organisms acquired in the
hospitals is complex and costly. To prevent cross-infection, it is necessary to identify the
different sources that facilitate transmission of pathogens to patients. One of the major
factors for cross-infection is the transfer of pathogens from the hands of healthcare workers
to patients (Pittet 2001,40-46). There is a need for appropriate method of cleaning and
disinfecting computer hardware in the hospitals if the number of microbes present on the
surfaces is to be reduced. Guidelines for hand washing and disinfection among the health care
workers should also be emphasized upon in order to improve the quality of patient care in
hospitals.
