Every time they spot a pool of stagnant water, they stop and inspect the puddle. Armed with dippers and sample containers, they are on the hunt for mosquito breeding grounds amid an outbreak of the deadly dengue fever.<\/p>\n
Makalla has become one of Yemen\u2019s worst-hit areas for dengue fever, a viral infection spread by mosquito bites that can cause fevers, headaches, body aches, nausea, and in severe cases, death.<\/p>\n
Bin Shabz kneels beside an open drainage chamber where a puddle of stagnant water, discharged from a household air conditioner, has turned green after standing for weeks.<\/p>\n
He dips a ladle into the water and pours the contents into a shallow metal tray. Within seconds, tiny larvae begin wriggling across the surface.<\/p>\n
\u201cThese are mosquito larvae,\u201d bin Shabz, an insect surveillance officer at the provincial office of the National Malaria Control Programme (NMCP), told Al Jazeera.<\/p>\n
\u201cThis type is Anopheles, which transmits malaria, while the other is Aedes, the mosquito that spreads dengue fever. We collect the larvae, place them in containers and identify them before taking the necessary control measures.\u201d<\/p>\n
The discovery confirms the team\u2019s fears: Al-Koud has once again become a breeding ground for both dengue and malaria mosquitoes, despite repeated campaigns to control the spread of the insects.<\/p>\n

\u201cWe carried out mosquito control campaigns in this area two months ago, combining public awareness, insecticide spraying and efforts to eliminate breeding sites,\u201d bin Shabz says. \u201cNow we\u2019ve returned and found many of the same breeding sites still exist.\u201d<\/p>\n
After draining the chamber, the team presses deeper into the neighbourhood. Minutes later, they stop outside another house where an uncovered water storage tank sits beside the entrance. Bin Shabz lowers a long-handled dipper into the tank and transfers another sample into a metal tray.<\/p>\n
\u201cThe tank is infested with both malaria and dengue larvae,\u201d bin Shabz confirms. He asks a group of curious children to fetch the homeowner so he can explain the dangers of leaving the water tank exposed and cover the container. \u201cA simple step like covering the tank would help protect his family and their neighbours from dengue fever,\u201d he said.<\/p>\n
To his disappointment, the homeowner is not there, so bin Shabz leaves a message with neighbours. But the mosquito breeding site will remain untouched until the owner can be reached.<\/p>\n
\u201cPeople are not cooperating with us,\u201d he said. \u201cIn urban areas, many residents are still asleep when we carry out our morning inspections, while others are away from their homes. Whenever we identify a breeding site, we speak to the homeowner, explain the risks and advise them how to eliminate it.\u201d<\/p>\n
Anti-dengue fever<\/p>\n
The vector control team in Mukalla is one part of a nationwide campaign across government-controlled areas of Yemen to curb a new outbreak of dengue fever. The campaign combines the surveillance of mosquito breeding sites with public awareness campaigns, insecticide spraying, larval control, and training health workers to diagnose and treat dengue cases in hospitals and local health centres.<\/p>\n
According to the Aden-based Electronic Integrated Disease Early Warning System (eIDEWS), which monitors disease outbreaks across government-controlled areas of Yemen, 7,815 suspected dengue cases and 33 deaths were recorded between January 4 and July 18, 2026. Hadramout was the hardest-hit governorate, reporting 2,204 cases, followed by Aden (1,639), Abyan (962), Shabwa (951) and Taiz (770).<\/p>\n
The dengue fever outbreak has placed further strain on Yemen\u2019s already fragile healthcare system, which has been pushed to the brink of collapse by years of war, chronic underfunding and repeated outbreaks of disease.<\/p>\n
Thousands of suspected dengue patients have sought treatment at hospitals across Aden, Taiz, Abyan and Hadramout, forcing overstretched health workers to cope with the surge despite limited resources.<\/p>\n
Mohammed Omer, head of the laboratory at the government-run Ibn Sina Hospital in Mukalla, recalled that at the height of the outbreak in May, the hospital received more than 60 suspected dengue cases in a single day. It placed an enormous burden on the hospital\u2019s emergency department, which serves patients from Hadramout, Shabwa and Al Mahra governorates.<\/p>\n
\u201cDuring one 24-hour shift, we used one and a half boxes of dengue testing kits to process samples from 65 suspected dengue patients,\u201d Omer told Al Jazeera.<\/p>\n
\u201cPatients come to our hospital because we provide free services, including laboratory testing, consultations and inpatient care,\u201d he said.<\/p>\n
Despite the availability of free services, many patients still arrived at the hospital in critical condition, often because they delayed seeking treatment. Financial hardship prevents some from travelling to the hospital, while others initially dismissed their symptoms as an ordinary fever.<\/p>\n

\u201cMany arrived late because they could not afford treatment, while others assumed it was just a passing fever and only sought medical help after it developed into severe dengue with bleeding symptoms, including nosebleeds. We also received destitute patients who could not afford medication,\u201d he said.<\/p>\n
Mohammed Salem Hadi, head of the NMCP office, said anti\u2011dengue efforts in Shabwa province continue to be hampered by limited funding, low public awareness and patients delaying treatment until their condition becomes critical. These are challenges common across much of Yemen.<\/p>\n
\u201cMany patients do not seek medical care until they develop severe dengue with haemorrhagic complications. This is often because they live far from health facilities, or because the disease is initially misdiagnosed as another illness,\u201d he told Al Jazeera.<\/p>\n
Challenges in tackling dengue fever<\/p>\n
The recurring dengue outbreaks have raised questions about why Yemen continues to struggle to contain dengue or reduce the number of deaths caused by the disease.<\/p>\n
Health experts and front-line workers put this down to a combination of factors, including the nature of the mosquito that transmits the virus, years of conflict that have weakened the country\u2019s healthcare system, inadequate vector-control programmes, poor sanitation and stagnant water. There is also the challenge for health workers of limited public awareness about dengue prevention and the importance of seeking early treatment.<\/p>\n
Abdulla bin Ghouth, a professor of community medicine at Hadramout University, said dengue fever has become endemic in Yemen and that the country\u2019s struggle to contain the disease is largely due to its biological characteristics.<\/p>\n
\u201cThere is no specific treatment for dengue fever; treatment focuses on managing symptoms and replacing lost fluids. There is also no specific vaccine available for prevention,\u201d he told Al Jazeera. \u201cThese factors, together with environmental conditions such as household water storage and high humidity, make the disease difficult to control.\u201d<\/p>\n
As he and his colleagues pack away their equipment and head off to search for another mosquito breeding site, bin Shabz acknowledges that eliminating the insects is an enormous challenge.<\/p>\n
Mosquito breeding sites are often hidden or difficult to access, he said, but Yemen\u2019s economic collapse and deteriorating public services have made the problem far worse.<\/p>\n
\u201cMany people cannot afford to build high-quality, properly sealed water tanks, so they rely on poorly constructed, uncovered tanks or even open ponds to store water,\u201d he said. \u201cWater shortages have forced many people to store water at home, creating ideal breeding sites for mosquitoes.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Mukalla, Yemen \u2013 Under the scorching sun and through heady humidity, Salem bin Shabz and his team of…\n","protected":false},"author":2,"featured_media":712557,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[242,59,102,464,632,50,56,54,55,25322],"class_list":["post-712556","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-features","tag-gb","tag-health","tag-infrastructure","tag-middle-east","tag-news","tag-uk","tag-united-kingdom","tag-unitedkingdom","tag-yemen"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/712556","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=712556"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/712556\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/712557"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=712556"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=712556"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=712556"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
