The Tennessee Health Department will start recontacting more than 1,000 people exposed to the New England Compounding Center's contaminated drug methylprednisolone acetate. The move is prompted by a rise in infections distinct from the initial meningitis cases. "While these infections are not as serious as meningitis, they need to be identified and treated to prevent them from becoming a more significant health problem," Tennessee Health Commissioner Dr. John Dreyzehner said.
