A stomach virus is spreading in Oklahoma City and ambulance officials said they've made a record number of calls in recent days.

Emergency Medical Services Authority spokeswoman Lara O'Leary said the ambulance service's former record for pickups was about 200.

She said EMSA passed that number of pickups three times this season with a one-day high of 213 on Monday.

Health officials said the stomach virus is a primary reason for the increased ambulance calls. Harold Holman with the Oklahoma City-County Department of Health said people are reporting symptoms to an illness known as the Norwalk virus.

He said the virus typically runs its course in three to five days and has no long-term effects. Holman said rest and drinking clear fluids are the best actions to take for the virus.
