U.S. health authorities said Thursday that more people than earlier thought received possibly tainted steroid injections and some 14,000 patients could be at risk of contracting meningitis in an unprecedented outbreak of the disease.
The U.S. Centers for Disease Control said the number of people at risk, which is 1,000 higher than earlier estimated, was revised after consulting with health authorities.
The CDC also said a Michigan patient is suffering from a joint infection after receiving treatment.
Fourteen patients have died from meningitis and 170 people have been infected, the CDC said in its latest update on Thursday. The number of infections ballooned by 33 since Wednesday, CDC said.
Florida reported a second death from meningitis, and Indiana reported its first death from the outbreak.
Meningitis cases have been confirmed in 11 states, but 23 states received shipments.
