On August 4, 2014, the Acute @entity166 Control Program of the Los Angeles County Department of Public Health received a report of three @entity5827 cases among football players at a county high school. An investigation was conducted to determine the extent of the outbreak, identify potential exposures, and recommend control measures. An outbreak-associated @entity5827 case was defined as an illness of any team or family member with onset during July 28-August 11 with 1) cerebrospinal fluid pleocytosis and negative bacterial culture or 2) an emergency department visit with @entity10 , @entity221 , and stiff neck. Ten cases were identified; nine in males, and one in a female; @entity1 ages ranged from 13 to 17 years. All the @entity1 sought care at an emergency department, and five were hospitalized, resulting in 12 total hospital days. All 10 @entity1 have recovered. Eight @entity1 were football players, and two were siblings of football players. The most affected subgroup was the junior varsity football team, with seven cases out of 57 players (attack rate = 12.3%); the relative risk for @entity5827 was higher among players who were linemen than among those who were not linemen (relative risk = 5.4 [p = 0.03]). Of the 10 @entity1 , eight tested positive by polymerase chain reaction for enterovirus, and two were not tested. Echovirus testing was performed at the California Viral and Rickettsial Disease Laboratory. Of the eight specimens testing positive for enterovirus, seven tested positive for echovirus 30, and one specimen could not be typed because of insufficient quantity.
