Twin Falls, Idaho (KMVT-TV) Two more people have died from fungal meningitis linked to tainted steroid injections, raising the death toll for the outbreak to 23.

So far, 297-people have been diagnosed with meningitis across the U.S. after receiving contaminated steroid injections in the spine as a treatment for back pain.

More cases are expected as the outbreak continues to unfold.

"Six months ago was probably before the tainted medication was released, a month ago they should be concerned. They should have been contacted by their physician or the facility concerning the medication if they received the medication that was tainted” said Dr. Clinton Dille, Southern Idaho Pain Institute.

Two shipments of the tainted medicine were sent to Idaho- one shipment to Emmett and the other to the Pain Specialists of Idaho Clinic in Idaho Falls.

Only one person has been diagnosed in the Gem State after receiving an injection.

"After they have had the injection I'm not certain it can be prevented, but however it's key they have early diagnoses and that way they can get after the treatment at an early opportunity than sit around and wait and allow the meningitis become full-blown and severe” said Dr. Clinton Dille, Southern Idaho Pain Institute.

Doctor Dille believes there are only a few doctors in the magic valley who administrate steroid injections.

"Including the Wood River Valley there are three to four that do these types of injections, however it's just not for epidural injections, but they could have gotten injections into joints as well and use the same medication” said Dr. Clinton Dille, Southern Idaho Pain Institute.

An outbreak that has turned into a major health scandal and is currently under investigation.
