1 Weekly Epidemiological Bulletin Flood Response in Pakistan Volume 1, Issue 8 onday 10 October 2010 Highlights Epidemiological week no 40 (2-8 October 2010) Between 2-8 October 2010 (epidemiological week no. 40), 48 of the 78 flood-affected districts provided surveillance data to the DEWS system. Of these 48 districts, 90% reported -7 days of the week. 55 fixed health and 153 mobile medical outreach centers provided surveillance data for this week. 32,071 consultations were reported through DEWS of which 20% were acute respiratory infections (ARI), 12% were acute diarrhoea, 13% were skin disease, and 8% were suspected malaria. 42 alerts were received and responded to this week: 2 alerts were for acute watery diarrhoea (, Suspected Cholera), 9 were for Viral Hemorrhagic Fever, 4 were for Acute Flaccid Paralysis (AFP, Suspected Poliomyelitis), 2 were for easles and 1 was for Bloody Diarrhoea. Ongoing malaria surveillance in collaboration with the alaria Control Program identified districts with higher than usual malaria transmission rates during peak Falciparum season. Districts Layyah, Rajanpur, DG Khan and uzaffargarh in ; Jacobabad, Larkana, Thatta and Khairpur in Sindh; Naseerabad, Sibi, Zhob and Jhal agsi in Balochistan. Seven of the 10 cases of poliomyelitis confirmed this week were from the flood-affected districts Note: All presented data are based on the number of patient consultations and include information on priority diseases under surveillance as well as major health events reported through DEWS.

Four districts with highest levels of malaria in are Layyah, Rajanpur, DG Khan and uzaffargarh.

DEWS is currently in place in 4 (82%) of the 78 flood affected districts and reporting is received from 48 (75%) of these 4 districts. The major causes for seeking healthcare by the affected communities continue to be diarrheal diseases, acute respiratory infections, skin diseases and suspected malaria. In, ARI decreased from 19% to 12% also AD continues to decline, however, it remains proportionally higher compared to the corresponding reporting period from (Please see Fig.13) In, a higher proportion of suspected malaria was reported this week (9% to 10%), although a peak of malaria in October reflects seasonal trend of diseases, DEWS officers are collaborating with alaria Control Program to investigate areas of increased malaria. Figure-13: AD trends,, 2009 and 2010 Percentage Weekly pattern of acute diarrhea, IDP crisis and hosting districts, Khayber Pakhtunkhwa ( ) Epi week Figure-14: alerts and confirmed cholera cases since July 29, 2010 In Sindh, proportional morbidity of major health events remained the same when compared to last week. In Balochistan, reporting remains irregular due to security issues. Suspected malaria continues to make up the largest proportion of consultations. WHO expert team has gone to Balochistan and will conduct outbreak investigation for malaria in collaboration with alaria Control Program. Focus on: alaria Every year Pakistan records about 4.5 million suspected cases of malaria and has evidence of about 1. million confirmed cases. September and October are the months for high transmission of Falciparum alaria, but out of 47 flood affected districts which are endemic for malaria, only nine are experiencing unusually high numbers of confirmed falciparum malaria cases. These districts are Layyah and Rajanpur in ; Jacobabad, Larkana, Thatta, and Khairpur in Sindh; and Naseerabad, Sibi, and Zhob in Balochistan. At the same time, DG Khan, uzaffargarh and Jhal agsi are still showing considerable number of vivax malaria cases. DEWS Teams are collaborating with alaria Control Dept and other partners to identify the malaria hot spots and bring a rapid response with medicines and appropriate vector control strategy. Preparation for malaria season started with distribution of anti malarial medicines in each of the emergency health kits deployed in flood affected districts. Provincial alaria Control Programs undertook indoor residual spraying as a vector control strategy in flood affected districts. WHO sent Rapid Diagnostic Tests (RDT) to the provinces to confirm cases of suspected malaria who were distant from microscopy centers. Supplies of primaquine tablets were distributed to areas with high vivax transmission while additional tabs of ACT SP were distributed to provinces with high numbers of falciparum cases. WHO, UNICEF, and UNHCR have distributed bed nets to the hotspots to increase coverage and protection of the population. 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. 0
