There’s no more information on the five people who contracted E. coli over five days in April.

Three adults have recovered, while College Station brothers 17-month-old Noah Melton and 4-year-old Jack Melton remain in fair condition at Texas Children’s Hospital in Houston.

The Brazos County Health Department says it’s possible they will never know the source of the bacteria, but investigators will work hard to try and find it.

It’s suspected three other adults contracted E. coli but those patients never went to the doctor, so health officials won’t be able to confirm if they’re part of this small outbreak.

They probably won’t make a song, like Five Days in May.
