The Government of Rwanda has officially declared the Marburg Virus Disease (MVD) outbreak over. No new cases have been recorded since the last patient tested negative on November 7, 2024, according to the World Health Organization (WHO).
1.The First MVD Case in Rwanda
The Ministry of Health of Rwanda confirmed the first Marburg outbreak on September 27, 2024. The Marburg virus, similar to Ebola, causes severe symptoms like high fever, headaches, vomiting, diarrhea, and bleeding. It can be deadly, with case fatality rates ranging from 23% to 88%, depending on the region and medical care available.
2.How Marburg Virus Spreads
Marburg is a zoonotic disease, meaning it can jump from animals to humans. It is spread mainly through prolonged exposure to bat habitats, such as caves and mines. Once infected, humans can transmit the virus through bodily fluids like blood and saliva.
3.The End of the Outbreak
The official countdown to end the outbreak began after the last confirmed case tested negative for Marburg on November 7. The 42-day countdown is twice the maximum incubation period for the virus. In total, there were 66 confirmed cases, including 15 deaths, making it the third largest Marburg outbreak reported. Nearly 80% of the patients were healthcare workers.
4.Rwanda’s Swift Response
Rwanda’s response to the outbreak was quick and effective. Supported by WHO, teams tested over 7,400 samples, with up to 350 samples tested daily. This strong response helped save many lives. Rwanda’s healthcare system followed well-prepared plans, which proved crucial in managing the crisis.
5.Challenges and Lessons Learned
The outbreak was particularly challenging because it spread across multiple districts and heavily impacted healthcare workers. The virus can spread quickly if not identified early, and strict infection control measures must be in place to protect healthcare staff.
There is currently no approved vaccine for Marburg, though several candidates are being developed. Early recognition and infection control are critical to protecting healthcare workers and limiting the spread of the virus.
6.The Role of Environmental Changes
Experts warn that climate change and deforestation could increase the risk of future outbreaks. As people move closer to bat habitats, the chances of coming into contact with the Marburg virus grow. Public awareness of how the virus spreads is crucial in preventing future infections.
7.Community Awareness and Preventive Measures
To reduce Marburg infections, it is essential to educate communities about the virus, especially human-to-human transmission. People with symptoms should contact health authorities immediately for treatment. Early medical care has shown to significantly improve survival rates, with 77% of patients surviving in this outbreak.
8.International Support and Expertise
The UK-Public Health Rapid Support Team (UK-PHRST) played a vital role in supporting Rwanda’s response. Three experts were deployed to assist in social science, risk communication, and infection control. Their work helped ensure that public health measures were effective and tailored to the community’s needs.
9.Ongoing Research and Future Preparedness
The London School of Hygiene & Tropical Medicine (LSHTM) continues to study Marburg virus and other filoviruses to improve outbreak preparedness. Research focuses on vaccines and better models to predict future outbreaks. The goal is to enhance global response capabilities and reduce the impact of such health threats.
10.Conclusion
Rwanda’s success in controlling the Marburg virus outbreak highlights the importance of early response, strong healthcare systems, and international cooperation. While the outbreak is over for now, ongoing vigilance and preparedness will be key to preventing future crises.
