The decade long conflict between the government and the Houthi movement escalated in 2015. The crisis has exacerbated historic vulnerabilities including chronic poverty, weak governance, corruption, over-dependence on imports, dwindling oil revenues, and water scarcity.? After President Hadi fled the capital Sana’a to the southern port city of Aden, an international coalition led by Saudi Arabia and the UAE began bombing Houthi-controlled areas. At least 24.1 million people in Yemen need humanitarian assistance.? In January 2019, some 64,000 people were in Catastrophe (IPC-5) levels of food insecurity, nearly 5 million people in Emergency (IPC-4) and 10.9 million in Crisis (IPC-3).?

Approximately 19.7 million people lack adequate healthcare, of whom 14 million are in acute need of assistance.? Around 300,000 suspected cholera cases and 578 deaths (CFR 0.19%) have been reported since the start of 2019.? From January to June 2019, there were 517,020 suspected cases and 755 deaths (CFR 0.15%) from cholera, which is already more suspected cases and deaths than what was recorded for the whole of 2018.? All governorates are affected, with 2,500 suspected cases reported daily. 17.8 million people lack access to WASH services, exacerbating the situation.? Fighting and bureaucracy restrict access to affected areas and the rainy season (April to August) will likely accelerate the spread of the disease. In Yemen, both rainy and dry conditions aggravate the spread of disease.

Widespread violations of international humanitarian law, including the targeting of civilians and civilian infrastructure by airstrikes and shelling, have resulted in loss of life, displacement, and destruction of infrastructure.? From the beginning of 2018 to the end of June 2019, approximately 6,850 civilian causalities and 2,650 civilian deaths have been recorded as a direct result of the fighting.? A UN-brokered ceasefire in December 2018 reduced violence in Al Hudaydah, however, fighting has continued on numerous active frontlines across the country. In 2019 an additional 300,000 people have been displaced bringing the total number of internally displaced people (IDPs) to an estimated 4 million people dispersed across all governorates. The majority having been displaced since March 2015.? Migrants and refugees, mostly from Ethiopia, continue to arrive in southern Yemen. April and May 2019 have seen some of the highest monthly averages of arrivals. IOM estimates that 18,320 refugees and migrants arrived in April 2019 and 18,904 people arrived in May 2019.? This is despite voluntary humanitarian return (VHR) flights coordinated by the Mixed Migration Working Group throughout May and June 2019 for migrants detained in informal detention centres with little to no services.

INFORM measures Yemen's risk of humanitarian crisis and disaster to be very high, at 7.8/10.?

Latest Developments


20/08:  The United Nations warned on 19 August that 12 major programmes are shut or drastically reduced due to the lack of funding and 20 other programmes will face further reductions or closure between August and September. The pledging conference hosted virtually by the Saudi Arabia on 2 June in support of the Yemen response fell short with a total of 1.35 billion USD -approximately half of the amount pledged in 2019- to cover 2.4 billion USD requested by humanitarian agencies in Yemen.Funding shortfalls come against the backdrop of re-escalating conflict, severe flooding, and a COVID-19 outbreak and with only 650 million USD of the 1.35 billion pledged received by the end of July hampering the humanitarian response in Yemen?

12/08: Heavy rains and flash floods since mid-July have killed 170 people and severely damaged shelters and public infrastructure in 17 governorates across Yemen. The most affected governorates are Al Hodeidah, Hajjah, Sana’a city, Ma’rib, Amran, and Lahj. Al Qanawis, Al Luhayyah, and Az Zuhrah districts (Al Hodeidah) and Bani Qays (Hajjah) were the most affected with atotal of 187 houses damaged or destroyed, and 7,000 people displaced. In Sana’a city 110 houses were partially or completely destroyed. Marib Dam flooded, affecting IDPs living in makeshift homes nearby. The highway connecting Dhamar, Ibb, and Taiz governorates was temporarily flooded, likely damagingroad infrastructure in the area. Flooding is expected to continue in the upcoming weeks, increasing health risks for the already vulnerable population, affected by previous floods and COVID-19 outbreak.? Read acaps briefing note on flooding 

6/08: 22 civilians including seven children were killed in an airstrike on three houses in the Khub wa Ash Shaf district of Al Jawf governorate. Airstrike incidents have increased by 139% in the first six months of 2020, compared to last six months of 2019. Further airstrikes are expected, as the Saudi-led Coalition announced a new air campaign against the Houthis on 1 July in retaliation for an increase in cross-border missile and drone attacks on Saudi territory. Airstrike incidents since May targeted predominantly Marib, Sa'ada, Al-Jawf, Hajjah, and Al Bayda governorates, with Marib governorate most affected. Even though the total number of civilian casualties has been decreasing since May 2020, civilian casualties caused by airstrikes have doubled.  ??

Humanitarian Access



Access continues to be very challenging due to conflict in the south between the Government of Yemen and the Southern Transitional Council (STC), and bureaucratic constraints in the north. Over 6 million people live in 75 hard to reach districts, with bureaucracy and conflict the main impediments to meeting humanitarian needs. Conflict blocks people from markets and services, particularly in Aden, Al Hodeidah, Ad Dhali’ and Hajjah. Fuel and gas shortages disrupt electricity, water, sanitation and health services and raise the cost of basic goods. On 20 June 2019, the World Food Programme suspended food distribution in Sana’a for over a month due to Houthi restrictions on beneficiary selection and monitoring. Project approvals in the north take over 100 days on average. Agencies in the south face challenges at checkpoints, particularly for northern staff. Access could decrease further if the Stockholm agreement, or Saudi-led talks in Jeddah, fail, resulting in renewed conflict.

COVID-19 epidemic in Yemen Latest update: 07/06/2020


Highly unlikely Somewhat likely Highly likely


Very low Moderate Major


As the COVID-19 virus continues to spread globally and international travel reduces, the virus continues to spread to neighbouring countries. Despite precautions by national authorities and WHO to minimise the risk of virus transmission, identification of an infected person already in Yemen, fails to self-isolate effectively and infects others. Due to a lack of test kits and fear of reporting, the virus spreads to many others before the authorities realise it is in country. Before long, crisis-affected vulnerable populations become infected. The virus spreads rapidly due to poor living conditions, high population density and poor hygiene practice.  The close proximity of dwellings, insufficient hygiene products and clean water access, and lack of public awareness continue to spread the virus to vulnerable people groups in Yemen.

Possible Indicators/Triggers:

  1. Confirmed cases increase surrounding countries
  2. Confirmed cases increase among humanitarian staff connected to Yemen
  3. Confirmed case in Yemen
  4. Insufficient test kits in Yemen
  5. Insufficient hygiene items
  6. Water prices rise
  7. Continued air travel into Yemen
  8. Lack of purchasing power among households to buy hygiene kits
  9. Poor health infrastructure


COVID-19 spreads rapidly through the population. A proportion of cases are hospitalised as hospitals struggle to implement sufficient protective measures for COVID-19 treatment wards. Within a month, many deaths are reported and increasingly stringent movement restrictions begin to be observed, but the number of infections and deaths continues to rise sharply. Death rates are higher than the global average due to the underlying poor health conditions, lowered immunity among malnourished population, and limited medical resilience in the general population.

COVID-19 is likely to be aggressively spreading through community level transmission in Yemen. The virus has likely been circulating undetected and unmitigated within communities and current predictions state it is likely that around 55% of the Yemeni population is going to get sick and over 42,000 people are going to die.

As of 20 July, Yemen officially reported 1,623 cases and 448 deaths from COVID-19, with the highest number of cases in Hadramawt, Aden, and Taiz governorates.  

Houthi authorities officially reported only four cases, including one death, in Sana'a city. Reports from inside the country suggest that the number of cases in northern Yemen are being seriously under reported. Authorities in the north have been accused of covering up positive tests and deflecting blame for the spread of the virus onto outsiders. In the south, increased mortality has been reported since early May in Aden city with an estimated 800 deaths due to symptoms similar to COVID-19. The full caseload is likely being under reported due to challenges with testing and reporting in Yemen's divided capital which is currently battling several disease outbreaks.

There's a concern that people experiencing multiple diseases are not tested for COVID-19 once they are diagnosed with another sickness. Many Yemenis in the north are reportedly afraid to seek medical attention due to reported harassment of those with symptoms. Humanitarian actors are concerned about protection issues and xenophobia against people associated with COVID-19 transmission like migrants, refugees, Yemenis moving between southern and northern governorates, and Yemenis returning from Saudi Arabia. Up to 100 Somali refugees were recently deported from areas under Houthi control to the south of Yemen. The spread of the virus is going to be exacerbated by population movements. An estimated 1,500 people fled Aden to other southern governorates like Lahj, Abyan and Ad Dali due to the spread of diseases and lack of services like electricity and water. 

Both the internationally recognized Government of Yemen (GoY) and the Houthis have imposed measures to control the disease. Movement between governorates was severely restricted for people and goods, except fuel and food imports. Both authorities announced restrictions including the closure of markets, shops, restaurants, and mosques. The authorities announced a partial curfew in Sana'a on all markets starting from 6:00pm to 6:00 am.  Reports indicate that people are not following restrictions which increases the risk of spreading the virus. 

The COVID-19 response is placing additional pressure on Yemen's health-care system, which is operating at roughly 50% of its pre-conflict capacity. It is likely that the impact of COVID-19 will result in further deterioration of public services, exacerbate food insecurity, and increase needs of WASH and health services, especially for those living in displacement sites. Delays of delivery of COVID-19 supplies have been reported, particularly of cargo arriving to northern governorates. ??
