Background:
In 2023, Sudan experienced a major cholera outbreak affecting 10 states amidst armed conflict that severely disrupted health services.
Objectives:
This study aimed to describe the magnitude and pattern of the cholera outbreak in Sudan amidst the armed conflict and provide timely insights.
Methods:
This was a retrospective record-based descriptive (cross-sectional) study. The study used surveillance data available at the national level (from August 2023 - February 2024). Epidemiological measurements were calculated, and data were analysed using Epi Info 7 software.
Results:
A total of 9,581 cases were reported in 10 states (with an overall attack rate (AR) of 3.5/10,000 people) and 238 reported deaths (with a crude case fatality ratio (CFR) of 2.48%). There was an observable variation in AR and CFR between the states. The duration of the outbreak varied across states, ranging from 4 to 18 weeks.
Conclusions:
Cholera caused significant mortality and morbidity, facilitated by conflict. To better address recurrent cholera and the challenges imposed by conflict, health authorities need to invest in communities through strengthening engagement, rising awareness and adopting community-based preparedness and response strategies. In addition, ensuring the readiness of the primary healthcare level requires training for healthcare workers and maintaining the flow of supplies.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
