Nosocomial outbreaks--a potential threat to the elimination of measles?

Area of Science:

• Pediatrics
• Infectious Diseases
• Public Health

Background:

• Measles outbreaks pose a significant public health threat, particularly in resource-limited settings.
• Nosocomial transmission of infectious diseases can undermine public health initiatives.
• The measles elimination effort in South Africa was underway during the described period.

Purpose of the Study:

• To describe a suspected nosocomial outbreak of measles among children.
• To investigate the transmission dynamics of measles within a hospital setting.
• To discuss the implications of nosocomial measles transmission on elimination strategies.

Main Methods:

• Retrospective case review of suspected measles cases in a pediatric ward.
• Epidemiological investigation to identify potential sources and transmission routes.
• Clinical and laboratory confirmation of measles infection.

Main Results:

• A measles outbreak occurred from June to August 1999, primarily affecting children within a hospital ward.
• Geographic data suggested community acquisition was unlikely for most cases.
• Evidence pointed towards in-hospital transmission, with most cases linked to a single ward.

Conclusions:

• Nosocomial transmission of measles is a significant concern, even during elimination efforts.
• Hospital infection control measures are critical to prevent measles spread.
• Outbreaks like this necessitate a re-evaluation of strategies to achieve measles elimination.
