Measles in health-care settings.

Despite the availability of an effective and safe vaccine for almost half a century, measles is re-emerging in several developed countries because of the insufficient vaccination coverage among specific subpopulations, the emerging anti-vaccination movement, and the increasing movement of humans across borders. In this context, health-care settings play a critical role in the transmission of infection and generation of numerous cases. Health-care-associated outbreaks may be associated with severe morbidity and mortality among specific groups of patients, disruption of health-care services, and considerable costs. Misdiagnosis or delayed diagnosis of a measles case and inadequate implementation of infection control measures are common in almost all events of nosocomial spread. Measles vaccination of health-care workers is an effective means of prevention of nosocomial measles outbreaks. Eliminating measles by 2010 has not been accomplished. Stronger recommendations and higher vaccination coverage against measles in health-care workers could contribute to eliminate measles in the general population.
