Point source epidemic of Mycoplasma pneumoniae infection in a prosthodontics laboratory
The American Review of Respiratory Disease
|August 1, 1975
Abstract:
A cluster of 10 cases of Mycoplasma pneumoniae infection involving persons working in a prosthodontics laboratory is descrbied. The pattern indicates a point source epidemic. The suspected mode of spread was a fine-particle aerosol generated from abrasive drilling of contaminated false teeth.
Insights
A Mycoplasma pneumoniae outbreak occurred in a prosthodontics lab, affecting 10 individuals. The infection likely spread through aerosols from drilling contaminated dental prosthetics.
Area of Science:
- Microbiology
- Epidemiology
- Occupational Health
Background:
- Mycoplasma pneumoniae is a common cause of respiratory infections.
- Prosthodontics laboratories involve procedures that can generate aerosols.
Purpose of the Study:
- To describe an outbreak of Mycoplasma pneumoniae infection.
- To identify the source and transmission route in a prosthodontics laboratory setting.
Main Methods:
- Case identification of 10 infected individuals.
- Epidemiological investigation to determine the outbreak pattern and source.
- Analysis of potential transmission routes within the laboratory.
Main Results:
- A cluster of 10 Mycoplasma pneumoniae infections was identified.
- The outbreak pattern suggested a point source epidemic.
- Aerosolized particles from abrasive drilling of contaminated prosthetics were the suspected transmission vehicle.
Conclusions:
- A prosthodontics laboratory can be a setting for Mycoplasma pneumoniae transmission.
- Fine-particle aerosols represent a significant risk for respiratory pathogen spread in such environments.
- Control measures should address aerosol generation during dental prosthetic procedures.
