The Global Alliance to Eliminate Lymphatic Filariasis (GAELF) reported this week that Yemen has eliminated lymphatic filariasis as public health problem, making them the 2nd country in the Eastern Mediterranean Region of the World Health Organization (WHO) to achieve this.

Yemen's success comes after almost 2 decades of tremendous efforts of sustained elimination measures as recommended by WHO of the 2 pillars -- mass drug administration (MDA) and morbidity management and disease prevention (MMDP) of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) strategy. After several rounds of MDA implementation, surveys since 2011 have validated that infection has been reduced to below transmission thresholds.

Transmission assessment surveys (TAS) conducted in 2013 and 2016 confirmed that Yemen had met all criteria for achieving elimination as a public health problem while, at the same time, management of morbidity in affected patients continued. Yemen will continue to improve its morbidity management programme treating patients with clinical symptoms as well as [maintaining] the appropriate level of surveillance to ensure continued zero transmission.

Lymphatic filariasis is caused by infection with parasitic worms living in the lymphatic system. The infection impairs the lymphatic system triggering abnormal enlargement of body parts, causing pain, severe disability and social stigma.

The larval stages of the parasite (microfilaria) circulate in the blood and are transmitted from person to person by mosquitoes.

The achievements of the Yemen PELF were made possible through the generous support and funding from the World Health Organization (WHO), the integration with the national leprosy programme (NLEP), the generous drug donations from the Mectizan Donation Program and GSK and the generous technical guidance of GPELF-WHO and GAELF.
=====================
[The problem of lymphatic filariasis in Yemen was realised around 2000, and in 2002 an initial pilot mass drug administration was implemented in Wisab subdistrict, Dhamar governorate (about 12,800 inhabitants) and 2 subdistricts on Socotra island, Hadramout governorate (about 29 000 inhabitants; El Setouhy M, Ramzy RM. Lymphatic filariasis in the Eastern Mediterranean Region: current status and prospects for elimination. East Mediterr Health J 2003;9:534-41.  <http://applications.emro.who.int/emhj/0904/9_4_2003_534_541.pdf>).

The location of Dhamar governorate can be found here:
<https://en.wikipedia.org/wiki/Dhamar_Governorate>.

Thus, filariasis was limited to the Dhamar governorate in central eastern Yemen and the Socotra island. Currently the Dhamar governorate is under control of the Houthi-led government in Sanaa (see <https://www.ecfr.eu/mena/yemen>), and Socotra is controlled by the United Arab Emirates.

Onchocerciasis, which is also considered a variant of filariasis, is still found in Yemen along the coastal areas toward the Red Sea (Al-Kubati A-S, et al. Onchocerciasis in Yemen: moving forward towards an elimination program. Int Health 2018;10 Suppl 1:i89-i96. <https://academic.oup.com/inthealth/article/10/suppl_1/i89/4868662>). - ProMED Mod.EP]

A cholera outbreak in Yemen has killed 686 people since the start of 2019, the SABA news agency reported on Monday [24 Jun 2019], citing Houthi health ministry spokesman Youssef Hadri.

Over 418 000 cholera cases have been reported in the country since January 2019, in addition to hundreds of malaria, dengue, diphtheria, meningitis, and chicken pox cases, Hadri said. The WHO said the number of suspected cholera cases between 1 Jan 2018 and 9 Jun 2019 had gone up to 759 464 in Yemen, with 1163 associated deaths.

This year's [2019's] outbreak, the 3rd major flare-up since the war began in Yemen in 2015, has affected 22 of 23 regions. Children under 5 represented a fifth of suspected cholera cases.  [Byline: Mohammad Ali]
======================
[The cumulative reported cholera total in Yemen from 27 Apr 2017 to 7 Jan 2018 was 1,029,717 suspected cholera cases and 2241 associated deaths. Adding in this information, in about 27 months, the total number of reported cholera cases in this war-torn country has reached about 1 790 000 with about 3300 fatalities. The calculated case fatality rate from this is quite low, strongly suggesting that many of the cases are not cholera. Even with that, the numbers reported in this continuing catastrophe are difficult to wrap one's head around. - ProMED Mod.LL]

Outbreak update - Cholera in Yemen, 27 May 2019
-----------------------------------------------
The Ministry of Public Health and Population of Yemen reported 16,827 suspected cases and 18 associated deaths during epidemiological week 20 (13-19 May 2019). 15 per cent of cases were severe. The cumulative total number of suspected cholera cases from 1 Jan 2018 to 28 Apr 2019 is 704 986, with 1114 associated deaths (case fatality rate [CFR] 0.16%). Children under 5 represent 22.6% of total suspected cases during 2019. The outbreak has affected 22 of 23 governorates and 295 of 333 districts in Yemen.

>From week 8 in 2019, the trend of weekly reported suspected cholera cases started increasing and peaked at more than 29 500 cases in week 14. During weeks 15 to 20, case numbers declined, although it is too early to conclude a downward trend. The decline may be attributed to enhanced outbreak control efforts such as community engagement and WaSH [water, sanitation, and hygiene] activities, and scaling up WHO and partners' response, including establishing additional DTCs [diarrhea treatment centres] and ORCs [oral rehydration corners].

The governorates reporting the highest number of suspected cases of cholera in 2019 are Amanat Al Asimah (55 065), Sana'a (41 094), Al Hudaydah (34 814), Ibb (31 725), Dhamar (29 889) and Amran (27 727).

Of a total 6144 samples tested since January 2019, 3264 were confirmed as cholera-positive by culture at the central public health laboratories. During this reporting period, the governorates reporting the highest number of positive cultures are Amanat Al Asimah (995), Taizz (741) and Sana'a (367).

WHO continues to provide leadership and support for activities with health authorities and partners to respond to this ongoing cholera outbreak, including case management, surveillance and laboratory investigations, hotspot mapping and oral cholera vaccination campaign planning, water sanitation and hygiene (WaSH), and risk communication.

Outbreak update - Cholera in Yemen, 12 May 2019
-----------------------------------------------
The Ministry of Public Health and Population of Yemen reported 18,171 suspected cases of cholera with 13 associated deaths during epidemiological week 18 (29 Apr-5 May) of 2019. 15% of cases were severe. The cumulative total number of suspected cholera cases from 1 Jan 2018 to 28 Apr 2019 is 668 891 with 1081 associated deaths (CFR 0.16%). Children under 5 represent 22.7% of total suspected cases during 2019. The outbreak has affected 22 of 23 governorates and 294 of 333 districts in Yemen.

From week 8 [18-24 Feb] in 2019, the trend of weekly reported suspected cholera cases started increasing and reached a peak of more than 29 500 cases in week 14 [1-7 Apr 2019]. During weeks 15 to 18 [8 Apr-5 May 2019] new case numbers began to fall, although it is too early to conclude a downward trend. The decline may be attributed to enhanced efforts to control the outbreak such as enhancement in the community engagement and WaSH [water, sanitation, and hygiene] activities, and scaling up of response by WHO and partners, including establishing of additional DTCs [diarrhoea treatment centres] and ORCs [oral rehydration corners]. Another factor is the 1st round of the OCV [oral cholera vaccination] campaign which took place in April 2019 in 3 districts of Amanat Al Asimah governorate, reaching 1 088 101 people (88% of the target).

The governorates reporting the highest number of suspected cases of cholera during 2019 were Amanat Al Asimah (50 166), Sana'a (36 527), Al Hudaydah (30 925), Ibb (26 421), Dhamar (26 421), and Arman (25 244).

Of a total 5610 samples tested since January 2019, 2920 have been confirmed as cholera-positive by culture at the central public health laboratories. During this reporting period the governorates which reported the highest number of positive culture were Amanat Al Asimah (893), Taizz (704), and Sana'a (342).

WHO continues to provide leadership and support for activities with health authorities and partners to respond to this ongoing cholera outbreak, including case management, surveillance and laboratory investigations, hotspot mapping and OCV campaign planning, water, sanitation, and hygiene (WaSH) and risk communication.

Khokha, Yemen, April 19, 2019 (AFP) - Oxfam has warned that war-torn Yemen risks a "massive resurgence" of cholera, with around 195,000 suspected cases of the disease recorded so far this year.   "Fears that the world's worst cholera outbreak could be set for a massive resurgence are growing," the relief organisation said Thursday.   It said aid agencies were struggling to reach suspected cases.

In a statement, Oxfam pointed to "fighting and restraints on access, including checkpoints and permit requirements imposed by the warring parties", and warned the coming rainy season was likely to accelerate the spread of the disease.   The water-borne bacterial infection has claimed more than 3,000 lives in Yemen since the outbreak began in 2016, according to Oxfam.

At a medical centre for the displaced in the government-held western town of Khokha, Qassem Suleiman had brought his son Alaa for tests after a serious case of diarrhoea.   Doctor Wadah al-Tiri told AFP that several patients had been transferred to Aden while others had been treated at the Khokha centre.   He said a tent was to be set up for suspected cases.

The doctor said Yemen badly needed international aid to combat the epidemic.   The UN's humanitarian coordination office OCHA said last month that children under the age of five make up nearly a third of this year's cases.   The spike, which comes two years after Yemen suffered its worst cholera outbreak, was concentrated in six governorates including in the Red Sea port of Hodeida and Sanaa province, both combat zones, it said.

Yemen's conflict, which pits Iran-linked rebels against a regional pro-government alliance led by Saudi Arabia, has left some 10,000 people dead since 2015 and pushed millions to the brink of famine.   Aid groups say the actual death toll could be five times as high.    The war has created the perfect environment for cholera to thrive, as civilians across the country lack access to clean water and health care.
