CONWAY, Ark. (KTHV) -- Burdick Hall on the University of Central Arkansas' campus is back open, but officials are still unsure of the cause of what made people sick.

UCA spokesperson Jeff Pitchford says all the air quality equipment showed there wasn't a problem with the air.

The Health Department & another air quality company came out to do more tests, and they also came out fine.

Another inspection will be done later this week to maybe try to determine the cause.
