Abstract

The aim was to describe an outbreak of group A β-hemolytic streptococcal pharyngotonsillitis in health care professionals. This is a cross-sectional descriptive study of 17 clients who dined at the same table in a restaurant in Barcelona in July 2012. The frequency, timing and severity of symptoms were analyzed, as were demographic variables and others concerning the food ingested. The attack rate was 58.8%. Six of the 10 clients were positive for group A β-hemolytic streptococcal. Six of the 13 individuals who handled the food involved in the dinner had symptoms. No association was identified with the food consumed. There is epidemiological evidence of foodborne group A β-hemolytic streptococcal transmission, but respiratory transmission could not be ruled out.
