In  Hong Kong, more and more elderlies are nowadays living in residential care  homes for the elderly. Infections among these elderly residents are not  uncommon. With intensive interaction among the residents, staff and visitors,  there is a potential of transmission of infections within the environment of  the elderly homes. In view of this, the Department of Microbiology,  Chinese  University of Hong Kong is going to host a Concise Course in Infection Control  for Residential Care Homes for the Elderly.
