SGH Hepatitis C Virus Cluster 5 Between April and September 2015, a cluster of 22 cases of acute HCV infection was identified amongst patients admitted to Ward 64A or Ward 67 at SGH. Subsequently, extensive screening of those who had been admitted to these wards from January to September 2015 identified three more cases, giving a total of 25 cases. Of these, 20 were renal transplant cases. There were eight deaths within the cluster. 6 SGH had conducted its own investigation into the cluster and taken actions to tighten infection control in the affected wards. It presented its investigation findings to the Minister for Health on 25 September 2015. On 28 September, MOH appointed an IRC to provide an independent, objective and critical review of SGH’s investigation and actions. The IRC was to ascertain if all possible measures had been taken to identify the possible points where there may have been infection control breaches and to remedy any weak points in the overall workflow, particularly with regard to infection control.
