Impact of War on Scabies Outbreaks: A Cross-Sectional Study in Argo, Northern Sudan, 2024
This 2024 cross-sectional study in Argo, Northern Sudan, reveals that the 2023 armed conflict has driven a scabies outbreak among displaced populations, where overcrowding, poor water and sanitation, and financial instability independently predict household transmission and delayed care-seeking, necessitating urgent targeted interventions.

In the crowded, chaotic aftermath of war, the most basic human needs often become the hardest to secure. When families are forced to flee their homes, they frequently end up in temporary shelters where space is scarce, water is unreliable, and privacy is a luxury. In these conditions, a common and intensely itchy skin condition called scabies can spread with terrifying speed. Caused by a microscopic mite that burrows under the skin, scabies thrives where people live in close quarters and cannot easily wash their clothes or bedding. While the mite itself is small, the consequences of an outbreak are large: the relentless itching disrupts sleep and daily life, and scratching the skin can lead to serious bacterial infections. For health workers, understanding how these outbreaks start and why they persist is not just a matter of treating a rash; it is a critical step in protecting the health of vulnerable populations who have already lost so much.
In the northern part of Sudan, a team of researchers set out to understand exactly how the ongoing conflict was fueling a scabies outbreak. Between August and November 2024, they worked in the city of Argo, a place that has become a major destination for families displaced by the fighting that began in April 2023. The researchers visited local hospitals, outpatient clinics, and shelters for displaced people to interview 155 individuals who were suffering from symptoms of the disease. They asked detailed questions about where the patients lived, how many people shared their home, whether they had access to clean water and soap, and how long they had waited before seeking medical help. The goal was to move beyond simple observation and identify the specific factors that were driving the spread of the infection and preventing people from getting treatment.
The picture that emerged was stark. The vast majority of the people the team studied had been forced to leave their homes. More than four out of five participants were displaced, and over half of them were living in crowded camps specifically designated for internally displaced people. In these settings, the disease had taken hold with alarming efficiency. Nearly nine out of ten people reported that someone else in their household was also suffering from the same itchy symptoms. The researchers found that the risk of the disease spreading within a home was nearly four times higher for displaced families compared to those who had managed to stay in their own neighborhoods. This high rate of transmission was not just a coincidence of bad luck; it was directly linked to the conditions of their new lives. Living in cramped quarters where more than two families shared a single residence, combined with a lack of clean water and sanitation facilities, created a perfect environment for the mites to jump from person to person.
While the environment helped the disease spread, money was the primary barrier to stopping it. More than half of the participants said they had delayed seeking medical care because they could not afford it. For the displaced families, financial instability was a constant reality, with most reporting that they did not have enough money for basic needs, let alone healthcare. The study showed that when people lacked funds, they often waited until their condition worsened, sometimes developing secondary infections from scratching, before they could see a doctor. This delay meant that the mites continued to spread unchecked within families and communities. The researchers used statistical methods to separate these different factors and found that while overcrowding and poor sanitation were key drivers of the infection itself, the decision to wait for treatment was almost entirely driven by a lack of money.
The findings from Argo paint a clear picture of a disease that is deeply tied to poverty and displacement. The study confirms that scabies is not merely a skin problem but a symptom of a broken system where healthcare is inaccessible and living conditions are unsanitary. The researchers concluded that to control the outbreak, simple medical treatment for individuals is not enough. Instead, they recommend a broader approach that includes improving access to clean water and soap, reducing the number of people living in single shelters, and providing free or subsidized medical care to remove financial barriers. They also suggest that in the most crowded camps, giving medication to entire groups at once might be necessary to stop the cycle of infection. By addressing the root causes of the outbreak—the lack of space, the lack of water, and the lack of money—health officials can hope to break the chain of transmission and bring relief to communities that have already endured too much.
