Transmission of Streptococcus pneumoniae in adults may occur through saliva.

摘要

Of 742 army recruits tested for pneumococcal nasopharyngeal/oropharyngeal carriage, 6.6 were positive. Frequent sharing of a drinking glass/bottle was a common, strong and independent risk factor for pneumococcal carriage. Our findings strongly suggest, for the first time, that in young adults, transmission of pneumococci may occur via saliva and this should be considered when conducting an outbreak investigation and carriage studies.
