With the case of Cynthia Zafer of Melbourne, Australia, the theory that often treatment can be more deadly than the disease, gained strength.

The dressing, marked sterilised, has since been identified as part of the export consignment received from Calcutta-based Jayer and Company, India's largest exporter of surgical dressings.
