A state funeral has been held in Pakistan for a German doctor and nun who devoted her life to battling leprosy. Ruth Pfau, who lived in Pakistan for more than 50 years, set up 150 leprosy clinics across the country. Her efforts meant that in 1996 the disease was declared to have been brought under control. <br/><br/>A member of staff at Dr Pfau's national leprosy centre, Yasmeen Morris, said her death is a big loss to humanity. She said, it is very hard to find a person like her in today's era. Dr. Pfau had died on the 10th of this month after protracted illness.
