Chad: Hepatitis E Outbreak - Sep 2016Ongoing
From 1 September 2016 until 13 January 2017, a total of 693 cases including 11 deaths of acute jaundice syndrome (AJS) have been reported from Am Timan, Chad. Based on the available information, there appears to be a plateau in the number of cases reported in the past 5 weeks from the affected area with an average of 70 cases reported weekly where only a minor proportion (7.2%) requires hospitalization. The infectious risk seems confined to Am Timan and immediate surroundings. However, the event remains under close monitoring at all levels of WHO. (WHO, 24 Jan 2017)
As part of the UNICEF response to the Hepatitis E suspected epidemic, WASH supplies for disinfection and water treatment were made available to the Amtiman Health District. (UNICEF, 31 Dec 2016) MSF, in addition to providing medical care, has also implemented hygiene and sanitation activities since this virus is primarily transmitted from one person to another through contaminated water and in areas where access to quality water is limited. More than 600 MSF staff have been working to test for new cases, treat patients and improve water supplies and sanitation in the city of Am Timan, including chlorination of the city’s water towers. (MSF, 9 Feb 2017)
The outbreak of hepatitis E in the Salamat region of Chad continues to evolve, with one new district being affected. The potential of the outbreak to escalate is high given the prevailing predisposing factors. Only 25% of the 63,000 people in Am Timan, the epicenter of the outbreak, have access to clean and safe water. Meanwhile, about 30% of the 13,000 people in Aboudeïa have access to safe water. The local community continues to fetch and drink water from rain pools (ponds), sharing with animals and birds. The affected communities also have poor sanitation, commonly practicing free range open defecation. With these factors, in addition to the onset of rainy season expected soon, the risk of further spread of hepatitis E, as well as of cholera, remains very high. (WHO, 14 Apr 2017)
In Chad, the outbreak of hepatitis E in the Salamat region of Chad remains serious, with a high risk of escalation. During week 28 (week ending 16 July 2017), 14 suspected cases and zero deaths were reported. As of 16 July 2017, 1,658 suspected/con rmed cases of hepatitis E, including 18 deaths (case fatality rate 1.1%) have been reported since the beginning of the outbreak in August 2016. Of the 18 deaths reported, ve (28%) were pregnant women. Overall, 65 samples tested positive for hepatitis E virus by MSF Holland and 33 by Pasteur Institute in Yaoundé. (WHO, 21 Jul 2017)

DAKAR/ GENEVA/ABUJA, 23 June 2017 –More than 5.6 million children are at increased risk of contracting waterborne diseases, such as cholera and diarrheal infections, as the rainy season begins in conflict-affected areas of countries around Lake Chad, UNICEF warned today. The threat of disease outbreaks in Cameroon, Chad, Niger and Nigeria coincides with growing regional insecurity and increased population movements particularly in Nigeria’s northeast.
Ongoing military operations in Niger and Nigeria are accompanied by a resurgence of attacks and incursions of armed elements, leading to protection incidents.

Le Tchad fait face à des crises humanitaires interconnectées, dans un contexte de pauvreté chronique et de faible développement économique. La situation sécuritaire dans les pays voisins a entrainé d’importants mouvements de personnes vers le Tchad, ainsi que des déplacements internes depuis plusieurs années. Des millions de personnes sont touchées par l’insécurité alimentaire et la malnutrition, en particulier dans la bande sahélienne et récemment dans la Tandjilé, cette situation risque de s’aggraver pendant la période de soudure (juin - sept.).
Chad is facing interconnected humanitarian crises in a context of chronic poverty and low economic development. The security situation in neighboring countries has led to large population movements into Chad, as well as internal displacement for several years. Millions of people are affected by food insecurity and malnutrition, especially in the Sahel belt, and recently in the Tandjile, this situation is likely to worsen during the lean season (June-September).
