1 Weekly Epidemiological Bulletin Flood Response in Pakistan Volume 1, Issue 21 Monday 10 January 2011 Highlights Epidemiological week no 1 (31 Dec 2010 to 6 Jan 2011) Between 31 Dec 2010 to 6 Jan 2011 (epidemiological week no. 1, 2011), 57 districts in 4 provinces provided surveillance data to the DEWS system. 2,159 fixed health and 11 mobile medical outreach centres provided surveillance data for this week. A total of 603,266 consultations were reported through DEWS of which 32% were acute respiratory infections (ARI), 8% skin disease, 6% acute diarrhoea, and 6% were suspected Malaria. Total 22 alerts in past two weeks were received and responded: 9 were for Measles, 4 for suspected Influenza, 3 for Meningitis, 2 for diphtheria, while 1 each for Neonatal Tetanus, Pertussis, Pneumonia and Viral Hemorrhagic Fever. There were no case of confirmed poliomyelitis reported this week from any area of flood affected district. 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.

6 Focus on: Vitamin A and Measles Measles is the greatest cause of vaccine-preventable death in the world, and every child should receive two doses of measles vaccine before age two. If a child develops measles disease, vitamin A can reduce the risk of dying from pneumonia. Most people only need one measles vaccination to protect them for a lifetime but about 5 percent to 15 percent of the population don't respond and need a second vaccination to protect them. Vitamin A deficiency puts unvaccinated or under-vaccinated children at higher risk for measles. In turn, measles can contribute to acute vitamin A deficiency. Vitamin A is found in foods like fish oils, liver, butter and egg yolk. Although vitamin A deficiency is often thought to be dietary, Vitamin A deficiency could also be due to inadequate absorption through malfunctions in our bodily system or loss of vitamin A due to infections or diarrhea. A systematic study of vitamin A for treating measles in children in 2005 considered eight trials encompassing 2,574 participants age 15 and under. The review concluded that two mega-doses of vitamin A given on consecutive days reduce the risk of dying from measles for children under age 2 years. Pneumonia was the most common cause of death in children with measles in the four studies that specified cause. Pooling data from studies that used two doses of vitamin A, the reviewers found: 67 percent reduction of mortality from pneumonia (429 hospitalized children), 41 percent reduction of post-measles croup (722 children studied), and 65 percent lower risk of developing diarrhea (474 children). Conclusion: Every measles case should receive two doses of vitamin A given on consecutive days. It is life saving. REFERENCE: Huiming Y, et al. Vitamin A for treating measles in children. (Review). The Cochrane Database of Systematic Reviews 2005, Issue 4, from Health Behavior News Service Influenza Update On 10 August 2010, WHO announced that the world is now in the post-pandemic period, but based on knowledge about past pandemics, the H1N1 (2009) virus is expected to continue to circulate as a seasonal virus for some years to come. While the level of concern is now greatly diminished, vigilance on the part of national health authorities remains important. Surveillance is currently focused on detecting any notable changes in the severity or other epidemiological or clinical characteristics of the H1N virus, including changes in the age distribution, the clinical appearance, proportion of cases requiring intensive management, or unexpected increases in numbers of cases are detected. In December 2010, most of the confirmed cases of influenza H1N1(2009) were outpatients detected during routine surveillance of influenza-like illness in sentinel sites. Due to the cost of the test and the new focus of surveillance, most samples are now taken from hospitalized patients or high risk patients. Further investigations are pending regarding the severity of the cases. All persons with influenza like illness and serious disease should start oseltamivir twice daily as early as possible, within the guidance of their physician. 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
