Aseptic meningitis outbreak associated with echovirus 30 among high school football players--Los Angeles County, California, 2014.
Echovirus 30 accounted for 4.5% of nonpolio enterovirus serotypes reported in the United States during 2006-2008 (1). Echovirus types 5, 9, 16, and 24 have been associated with aseptic meningitis outbreaks in football teams (2,3). However, this appears to be the first documented echovirus 30 aseptic meningitis outbreak in the United States among members of a sports team.
Investigators from the Acute Communicable Disease Control Program determined the most likely factors resulting in transmission included water bottles shared among football players, inadequate washing of water bottles, and poor hand hygiene. School staff members notified parents of the outbreak and likely mitigated infection sources. Summer football league games between the affected high school and nearby schools posed a risk for spread of infection; however, investigators pursued active case-finding in area hospitals and schools and identified no additional cases. School staff members were asked to encourage proper hand hygiene and discourage shared water bottles to avoid future outbreaks.
