Diphtheria is making an alarming comeback in the war torn country, with 189 clinically diagnosed cases and 20 deaths – mostly children and young adults – in the last three months. Most diphtheria cases and deaths have been reported in Ibb governorate but the outbreak is spreading fast, already affecting 13 governorates. The closest points of entry to Ibb are in Sana’a and Hodeida, making it crucial that Sana’a airport and the port of Hodeida remain open. (WHO, 27 Nov 2017)

By 4 December, 318 suspected cases of diphtheria and 28 deaths had been reported in 15 of Yemen’s 20 governorates. Half the suspected cases are children between the ages of 5 and 14, and nearly 95% of deaths are children under 15. Nearly 70% of all suspected cases are in Ibb governorate. (MSF, 12 Dec 2017)

312 suspected cases of diphtheria have been reported in Yemen between mid-August and 20 December. The outbreak has resulted in 35 deaths reported. At 11%, the case fatality rate (CFR) is high. 18 out of Yemen’s 22 governorates are affected, with Ibb having the majority of cases. (ACAPS, 22 Dec 2017)

WHO reported on 11 January 2018 that diphtheria-related deaths had been recorded in 19 governorates. Across the country, 610 suspected cases have been reported. The diphtheria outbreak occurs against the backdrop of a cholera epidemic accounting for more than 2,200 lives lost and more than one million suspected cases reported, since April 2017.
