Those who have not received a flu shot this season are invited to The Dell Diamond before the Aug. 21 Round Rock Express game to learn about the symptoms and effects of the illness.

FLUgitives, a national health initiative, aims to spread awareness about the flu with a variety of flu-themed activities. Participants can see how the flu can affect their physical appearance with the FLUify photo application, learn about vaccination options and win prizes.

The event takes place at 7 p.m. at The Dell Diamond, 3400 E. Palm Valley Blvd., Round Rock. For more information, call 415-946-1080 or visit www.flugitives.com.
