Health workers in Yemen are scrambling to contain a new dengue fever outbreak as concern grows over increasing infections. In Mukalla, teams are working in punishing heat and humidity as they try to slow the spread of the mosquito-borne disease.

The response is focused in part on Al-Koud, a densely populated area where narrow alleyways and difficult living conditions can make disease control harder. The latest outbreak has put added pressure on frontline staff, who are moving through crowded neighborhoods to reach vulnerable communities.

Dengue fever remains a serious public health threat in places where mosquitoes can spread quickly, especially when health systems are already under strain. In Yemen, the renewed rise in cases has raised fears that the outbreak could worsen if it is not brought under control.

The situation in Mukalla highlights the challenge facing Yemen’s health workers: trying to hold back a deadly disease while operating in harsh conditions and densely settled urban areas. Their efforts reflect the urgency of preventing further infections as the outbreak develops.
