According to the Disease Early Warning
According to the Disease Early Warning System, infectious diseases were widespread during the flood, including cases of cholera, malaria, and polio, consistent with exposure of displaced people to disease corticotropin-releasing factor and conditions of poor hygiene in camps and shelters. Disruption to the management of existing chronic diseases is another concern in emergencies, as is the plight of vulnerable groups including older people and children who are at risk of infectious disease, dehydration, and malnutrition.
The Global Polio Eradication Initiative (GPEI) reports that there are four sanctuaries for the polio virus in Pakistan: Karachi, Quetta, and the districts of Qila Abdullah and Pishin. 58 cases were reported from Pakistan in 2012. Polio prevention is not only a national health problem but a social, religious, cultural, security, and political issue in Pakistan. Violence against polio vaccine workers, particularly the killing of female workers in Karachi and Baluchistan, signifies a need for urgent reprogramming of Pakistan\'s public health approach.
