He injured his left hand while preparing a fish dinner at home. On November 2, his injured hand grew swollen and he developed a fever. He was admitted to United Christian Hospital that day and is now in the intensive care unit in serious condition.

Necrotising fasciitis is a serious bacterial infection of the soft tissue and fascia. It can destroy tissue and cause death within 12 to 24 hours after infection.
