 I have the opportunity to present our rapid and nutritional mortality in Ban Ki area in north of Nigeria. Since 2014, attacks by Boko Haram have intensified in north-eastern Nigeria, leading to the displacement of almost three million of population across charge Niger, Cameroon, as well as Nigeria. In 2015, most of the territory that was controlled by Boko Haram in northwest Nigeria has now been taken over by Nigeria Army. This situation produces a massive displacement into area that are comparable to the camp. MSF was present in several camps in Nigeria, as you can see in the map, as well as in Cameroon and Chad. Essentially, Ban Ki was closer to a comfortable place than the camp. There are between 15,000 and 25,000 people there, and people were confident there for more than six months, and people living in extremely depriving conditions. For example, there are no markets in Ban Ki, there are limit movement of population, there are limit access to safe drinking water and sanitation. Also, humanitarian assistance was managed by Nigeria Army and local volunteers. MSF did an initial nutrition and mortality assessment in Ban Ki in July. At the same time, we implemented a blanket filling and miziz vaccination of children under five, as well as distribution of non-food items. A rapid assessment showed a good mortality rate four times above emergency threshold, as well as very hard living of nutrition. To address this critical situation, we implemented from July to December a strategic combination preventive, curative, as well as water and sanitation activities. Preventive was miziz vaccination for all children under 15 years, three rounds of seasonal malaria and vitamin distribution. The main focus of medical care was nutritional care because malnutrition rate was so high. So we decided to keep it as simple as we could. We used miac only for screening, we used plampinates only for all children. For children with several malnutrition, we give 13 sachets plampinates, and for all over children, we give 16 sachets plampinates. So all children was given plampinates. We think this is very important. In added, we give families protection ration of high-energy biscuits as well as moscow net, and so in order to monitor the situation and the effect of MSF intervention, MSF in collaboration with Episome decided to implement regular mortality survey. I am going to talk about the method. We did a repeated mortality survey. We used random and systematic samples to select households. And for data collection, we used a simplified form, content only system and variant. We also defined very short recall period to limit any bias. We did three mortality survey, and the last survey we investigated also malnutrition. You can see on my slide the results. The main results you can see here is about the good mortality rate decrease from 3 deaths per 10,000 people per day to 0.3 deaths per 10,000 people per day. The under five mortality rate decrease from 5.6 deaths per 10,000 people per day to 1.7 and to 1, respectively across the type. Most of the deaths come in banki, not during the displacement of population. In the third survey, we have a malnutrition and we can see that a global acute malnutrition was 1.6 and several acute malnutrition was 0.2. We have some limitation for our survey. We didn't collect individual data, so it was not possible to describe age pyramids. Arrival and departure not taken into account. No repeated malnutrition survey, so we can't follow malnutrition thing over the time. What about the conclusion? So we present here an overview of humanitarian emergencies in banki and effort of MSF time to provide assistance in a tenacious security situation. Despite difficult access, MSF team could organize a comprehensive target package to intermediate visits. The last repeated survey was able to replace the surveillance system due to the high rent and security and with limited access of MSF to the banki area. I want to know the communities of banki MSF flight staff and driver in Camun and MSF staff in Geneva and in Paris. Thank you.
