Background:
Mycoplasma pneumoniae is a major cause of respiratory infection of varying severity. Outbreaks of M. pneumoniae infection commonly occur in closed or semi-closed communities and settings. The control of such outbreaks is challenging, owing to delayed detection, long incubation period, and paucity of infection control guidelines.
Methods:
Between May and July 2015, a residential facility for adults with developmental disabilities in Southern Israel witnessed an outbreak of acute respiratory infection, subsequently diagnosed as associated with M. pneumoniae. All relevant data were collected as a part of a formal outbreak investigation. Strict infection control procedures were implemented, and azithromycin prophylaxis was provided to all residents.
Results:
Out of 215 residents, there were 29 suspected cases, 23 of which were confirmed as M. pneumoniae infection by serology or nucleic acid testing, for an attack rate of 11%. There were no cases of severe or fatal illness. An infection control strategy, including implementation of strict case isolation, enforcement of hygiene measures, a high index of suspicion for case detection, and use of azithromycin prophylaxis for all residents, led to rapid cessation of the outbreak.
Discussion:
The use of azithromycin prophylaxis may be worthwhile in closed institutional settings in which M. pneumoniae infections are documented. The dynamics of this outbreak suggest that if spread between wards is anticipated, expanding prophylaxis beyond immediate contacts of affected individuals should be considered.
Insights
Mycoplasma pneumoniae outbreaks in residential facilities can be controlled. Azithromycin prophylaxis for all residents, alongside strict hygiene and isolation, rapidly halted an outbreak, suggesting its value in institutional settings.
Area of Science:
- Infectious Diseases
- Public Health
- Epidemiology
Background:
- Mycoplasma pneumoniae causes significant respiratory infections, particularly in communal settings.
- Controlling M. pneumoniae outbreaks is difficult due to long incubation periods and limited guidelines.
- Residential facilities for vulnerable populations are susceptible to M. pneumoniae transmission.
Purpose of the Study:
- To investigate and control a Mycoplasma pneumoniae outbreak in a residential facility.
- To evaluate the effectiveness of infection control strategies, including azithromycin prophylaxis.
Main Methods:
- Conducted an outbreak investigation in a Southern Israel residential facility from May to July 2015.
- Implemented strict infection control measures: case isolation, hygiene enforcement, and high suspicion for detection.
- Administered azithromycin prophylaxis to all residents.
Main Results:
- Identified 23 confirmed cases of M. pneumoniae infection among 215 residents, with an 11% attack rate.
- No severe or fatal illnesses were reported during the outbreak.
- The implemented control strategy, including prophylaxis, led to the rapid cessation of the outbreak.
Conclusions:
- Azithromycin prophylaxis is a potentially valuable intervention for M. pneumoniae infections in closed institutional settings.
- Broadening prophylaxis beyond immediate contacts may be necessary if inter-ward spread is a concern.
- Effective outbreak control relies on a multi-faceted approach including prompt detection and intervention.
