The health ministry inspected Teikyo University Hospital in Tokyo on Monday over the deaths of inpatients infected with antibiotics-resistant bacteria and the institution's late reporting of the situation to authorities.
It was the first time the central government conducted an on-site inspection of the hospital since the infections came to light last week. Tokyo Metropolitan Government officials joined the inspection.
Meanwhile, the Metropolitan Police Department has begun questioning doctors and others at the hospital on a voluntary basis as part of an investigation into alleged professional negligence resulting in death.
