Four of the 9 cases of poliomyelitis confirmed this week were from the flood-affected districts Emergency conditions exist for over,000 people in Dadu District of Sindh who are stranded without food or shelter on bits of land surrounded by water. AWD alert was received on 23 October of 50 year old male with diarrhea and serious dehydration in Tent City Kakar at Dadu. 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.

In Punjab, a higher proportion of suspected malaria was reported again this week (11% to 13%), although a peak of malaria in October reflects seasonal trend of diseases, DEWS officers are collaborating with Malaria Control Program to investigate areas of increased malaria, providing rapid diagnostic test and appropriate medicines. % of total consultations Acute Diarrhoea 9,447 9% 74% Figure-7: Trend of priority communicable diseases, province Punjab (3 August - 22 October 2010) Figure-8: Proportional morbidity of priority diseases, Punjab province UF 3% 9% 13% 20,3 20% Skin 11,673 11% Suspected malaria 13,447 13% 44% 20%,1 % Total consultations 103,588 11% 04

6 Summary of Health Event in Flood affected districts Since July 29, 2010, approximately 7,622,4 patient consultations have been reported to DEWS from the flood affected provinces in Pakistan. DEWS is currently in place in 64 (82%) of the 78 flood affected districts and reporting is received from 50 (78%) of these 64 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 KPK, increased from 12% to 14% also continues to decline, however, it remains proportionally higher compared to the corresponding reporting period from (Please see Fig.13) Figure-13: trends, KPK, 2009 and 2010 Percentage ly pattern of acute diarrhea, IDP crises and hosting districts, Khyber Pakhtunkhwa ( ) Epi week Focus on: Dengue Fever and Dengue Hemorrhagic Fever So far about 4,3 cases of suspected Dengue Fever (DF) have been reported in Pakistan with about 2,062 confirmed cases and 15 deaths. As Dengue Fever cases are on the rise in many places across the country, Pakistan joins % of the global community who are at risk for Dengue, the most widespread mosquito borne infection in human beings. The only way to prevent Dengue Fever is to prevent mosquito bites. Dengue is not spread by droplets or blood. Dengue mosquitoes bite during the daytime. To protect yourself wear full sleeve clothes and long trousers, avoid wearing black color, use repellents, use mosquito coils and electric vapor mats, use bednets for children and elderly who may rest in bed during the day. To control Dengue in the community, we must reduce the places where mosquitoes live and breed: drain out the water from all unused tanks, barrels, drums, and buckets and cover all stored water containers. Remove garbage piles where water collects in discarded containers. As 95% of Dengue Fever can be treated at home, when someone falls ill with a fever and headache, pain behind the eyes, or body aches and no other symptoms, the best advice is to rest at home in bed, take plenty of fluids like soup, water, milk and juice, and take paracetamol (Panadol, Calpol, etc) for pain. All dengue patients must be carefully observed for complications for at least 2 days after recovery from fever because life threatening complications often occur during this phase. Patients and households should be informed that severe abdominal pain, passage of black stools, bleeding into the skin or from the nose or gums, sweating, and cold skin are danger signs. If any of these signs is noticed, the patient should be taken to the hospital. Please use only paracetamol for pain and fever as other medicines may increase the bleeding tendency. At the hospital, the patient is monitored with frequent blood pressure readings, tests of hematocrit and platelets to determine when to give intravenous fluid and how much to give. Blood or platelets may need to be given if the patient is actively bleeding. The four WHO criteria for diagnosis of Dengue Hemorrhagic Fever, fever with headache or body aches; evidence of bleeding or positive tourniquet test; platelet count less than 100,000; and evidence of leaky capillaries such as >20% rise in hematocrit, have been found to be 62% sensitive and 92% specific for identification of dengue illness requiring intervention.

Dengue Hemorrhagic Fever: The Sensitivity and Specificity of the WHO Definition for Identification of Severe Cases of Dengue in Thailand, Clinical Infectious 2010;50: 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. 06
