Epidemiological Bulletin: Flood Response in Pakistan
The objective of this weekly epidemiological bulletin is to provide a snap shot on selected health events reported from the communities affected by the current flood in Pakistan. While every attempt is made to present the weekly trend of the epidemic prone diseases, the information presented in the bulletin needs to be interpreted in the context that precise information on the reference populations is not always available, The bulletin also includes information collected by DEWS teams established during earlier emergencies, including 2005 earthquake, 2007 floods and 2008 ID crises. The primary focus of DEWS is the early detection of epidemic prone diseases, to facilitate a rapid public health response. We would like to thank all the numerous national and international partners who have contributed to the Disease Early Warning System.
We are pleased to report that a journal article on “The impact of the disease early warning system in responding to natural disasters and conflict crises in Pakistan” has been published in the Eastern Mediterranean Health Jour-nal (Rahim M, Kazi BM, Bile KM, Munir M, and Khan AR, vol 16, supp 2010, S114-S121). The article covers the 2005-2009 introduction of DEWS and “aims to report the DEWS success and substantiate its lead role as a priority emergency health response intervention.” Quoting from the abstract, “the disease early warning system (DEWS) was introduced in the immediate aftermath of the 2005 earthquake in Pakistan, with the objective to undertake prompt investigation and mitigation of disease outbreaks. The DEWS network was repli-cated successfully during subsequent flood and earthquake disasters as well as during the 2008-09 internally dis-placed person’s crisis. DEWS-generated alerts, prompt investigations and timely response had an effective contri-bution to the control of epidemics. Through DEWS, 1368 reported alerts during 2005-09 averted the risk of dis-ease outbreaks through pre-emptive necessary measures, while the 187 confirmed outbreaks were effectively con-trolled. In the aftermath of the disasters, DEWS technology also facilitated the development of a disease-surveillance system that became an integral part of the district health system.” During the reporting period, “among priority epidemic-prone diseases, acute watery diarrhea was the leading health problem with 85 (45%) outbreak events, followed by measles with 33 (18%) outbreaks, dengue fever 21 (11%) outbreaks and acute hepatitis viral infection with 16 (9%) outbreaks (of the confirmed cases, seven were hepatitis E and three were related to hepatitis A), while bloody diarrhea accounted for six (3%) outbreaks.” Other outbreaks which were identified and controlled by DEWS included “avian influena, influenza H1N1, cuta-neous leishmaniasis, chicken pox, food poisoning, mumps, tuberculosis, pertussis, diphtheria and typhoid.” Weekly trend graphs for Acute diarrhea, Acute respiratory tract infection, and Measles over four years 2006 to 2009 are also displayed in the article and form the basis for two of the graphs in our current weekly bulletin.
