Abstract

We report on an outbreak of Group A Streptococcus (GAS) pharyngitis among university students in a judo club. Eventually, 14 of total 23 club members developed acute pharyngitis clinically. In a span of 15 days in April 2013, 12 students visited our hospital complaining of sore throat and high fever. All were men with a median age of 19.5 years (interquartile range, 18–21). The rapid streptococcal antigen test was positive in 3 of 4 patients (75%) without previous antibiotic treatment, and in 2 of 8 patients (25%) with previous antibiotic treatment. The definitive diagnosis of GAS pharyngitis was made by either a positive RADT or positive throat culture of GAS when patients had more than 2 findings from the Centor scoring system in this study. 5 students received the definitive diagnosis. The throat culture results showed that 1 out of 9 asymptomatic students was GAS-positive. The outbreak might have occurred by person-to-person contact while living in a dormitory and during judo training, which is a highly close-contact sport. However, there was also the possibility of oral transmission by the shared use of water bottles, although the culture from 1 bottle was negative. Some students continued to participate in the judo club activities after the onset of sore throat or fever. Healthcare professionals, teachers, and coaches should be aware of the potential outbreaks of infectious diseases among university students engaged in athletic activities. Furthermore, it is important to educate athletes about infectious diseases.
