After running tests, the consultant informed Reuben's mum Chloe Harris that she believed Reuben might have bacterial meningitis but that they need to confirm the diagnosis with a lumbar puncture. The consultant then stated that due to their suspicions, they've started to treat Reuben with antibiotics.
