Situation at a glance
As of 9 November 2024, Rwanda has officially initiated a crucial 42-day countdown period that may lead to the declaration of an end to the Marburg virus disease (MVD) outbreak, following the last confirmed patient’s negative PCR test. Health authorities have reported a total of 66 confirmed cases, tragically including 15 fatalities, resulting in a high case fatality ratio (CFR) of 23%. Fortunately, 51 individuals have successfully recovered from the illness. Notably, no new confirmed cases have emerged since 30 October 2024. The outbreak will be officially declared over only if the 42-day countdown concludes without any additional infections. The World Health Organization (WHO) is actively supporting the Government of Rwanda as they navigate the response to this critical health emergency. Ongoing surveillance and strict infection prevention and control (IPC) measures are paramount until the outbreak is formally declared over.
Description of the situation
Since the last Disease Outbreak News on 1 November 2024, Rwanda has not witnessed any new confirmed cases of Marburg virus disease (MVD). The total confirmed cases now stand at 66, which includes 15 deaths—prompting a devastating case fatality rate of 23%. Among the confirmed cases, a striking 68% are male, with 45% identifying as adults in the age group of 30 to 39 years. Alarmingly, nearly 80% of all confirmed cases originate from health workers at two health facilities located in Kigali, with most cases reported from three districts within the city.
The highest number of confirmed cases, totaling 61, were identified during the initial three epidemiological weeks (weeks 39-41) of the outbreak. Following this peak, the country experienced a significant drop in cases, recording three or fewer cases during the periods of epidemiological week 42 (14 to 20 October) and week 44 (28 October to 3 November) respectively.
As of 8 November 2024, approximately 7408 tests for the Marburg virus have been conducted, with daily testing rates fluctuating between 100 and 350 samples at the Rwanda Biomedical Center.
The 42-day countdown officially commenced on 9 November 2024, marking a critical time period given it is twice the maximum incubation period for Marburg virus infections. The countdown starts after the last confirmed patient tested negative for the virus. Throughout this countdown, all known contacts will be monitored until their individual 21-day observation periods conclude. The ultimate goal remains clear: to officially declare the outbreak over if no new cases are observed during this period.
WHO continues to diligently collaborate with the Government of Rwanda to bolster its response efforts regarding the ongoing outbreak. Enhanced surveillance and strict IPC measures must be maintained continuously until the outbreak is declared definitively over.
Epidemiology
Marburg virus disease (MVD) presents symptoms that begin abruptly, characterized by high fever, severe headache, and intense malaise. By the third day of illness, severe watery diarrhea, abdominal pain, nausea, and vomiting may manifest. While not all cases exhibit hemorrhagic signs, severe bleeding can occur approximately five to seven days post-symptom onset. Fatal cases typically manifest some form of bleeding, often originating from multiple sites within the body. Tragically, death in these cases often transpires between eight and nine days after the onset of symptoms, generally following significant blood loss and shock. Currently, there exists no approved treatment or vaccine for MVD, though several candidate vaccines and therapeutic measures are undergoing investigation.
Public health response
- The Government of Rwanda is leading the response with support from WHO and various partners.

WHO risk assessment
Marburg virus disease (MVD) is caused by a virus belonging to the Filoviridae family, which also includes Ebola. This disease is notable for its potential to cause severe epidemics, often associated with case fatality ratios ranging from 24% to 88%. One of the key challenges in the early stages of MVD is distinguishing it from other infectious diseases, including malaria, typhoid fever, and shigellosis. Understanding epidemiological clues, such as potential exposure to bats or areas associated with mining, is vital for diagnosis, which must ultimately be confirmed via laboratory testing.
The investigation indicates that the source of the outbreak is zoonotic, likely related to exposure in a cave occupied by fruit bats. Unfortunately, the exact dates for the onset of symptoms among affected individuals remain unknown to WHO.
MVD does not spread easily under casual conditions; typically, it requires direct contact with the body fluids of symptomatic patients or through contaminated surfaces. Active public health measures are being implemented, including surveillance, testing of suspected cases, isolation, treatment, and contact tracing.
WHO advice
Effective control of MVD relies on a multifaceted approach, which includes strict isolation of cases, rigorous surveillance mechanisms, and robust community engagement efforts. Awareness-raising about the risk factors associated with MVD, particularly regarding human-to-human transmission, is essential for reducing infection rates. WHO strongly advocates for the following risk reduction measures:
- Community awareness must emphasize the need for immediate medical attention for individuals exhibiting MVD symptoms to mitigate community transmission risks.
- Implement rigorous preventive practices for those who may encounter bats, like wearing appropriate protective clothing when entering caves or mines.
- Strengthen surveillance activities across affected districts, ensuring active and accurate case identification and established contact-tracing protocols.
- Immediate and effective IPC measures should be enforced within every healthcare facility, as outlined in WHO’s established guidelines to prevent healthcare-associated infections.
- Patient-care should occur in environments that uphold strict hygiene and infection prevention standards, with adequate infrastructure for sanitation and clean water availability.
- A comprehensive strategy for safe burials must be adopted to promote dignity and respect for deceased community members.
- Qualitative data collection is essential for tailoring responses to community needs and behaviors.
- Ensuring timely laboratory evaluations for suspected cases is crucial for action and response effectiveness.
- WHO encourages sharing genomic sequencing data to aid public health actions.
- Readiness and response capabilities at borders should be fortified to manage any potential MVD cases crossing over from affected areas.
- Countries are encouraged to routinely submit samples that tested positive for Marburg virus to WHO Collaborating Centres for comparative analysis.
- A systematic approach to collecting clinical data from suspected and confirmed cases will enrich the understanding of MVD and its varying outcomes.
- Given the possibility of a resurgence of MVD cases, active surveillance must continue for at least six months beyond the current outbreak period.
- All patients diagnosed with MVD should receive comprehensive and supportive care, especially regarding critical and mental health services within specialized treatment centers.
- Developing care programs for MVD survivors is vital for their recovery and for minimizing risks associated with body fluid transmission.
In light of the current situation, WHO advises against imposing any travel or trade restrictions with Rwanda. For comprehensive guidance, visit WHO recommendations regarding international travel amid the outbreak.

Introducing the Marburg Virus Chronicles from Rwanda!
Hold onto your hats, folks! On November 9, 2024, Rwanda kicked off a 42-day countdown to declare the end of its Marburg virus disease (MVD) outbreak. Yes, we’ve reason to pop the party poppers, but let’s not get ahead of ourselves. That countdown only began after the last confirmed patient tested negative via the all-important PCR test. So, what’s the story thus far? We’re looking at 66 confirmed cases, a disheartening 15 deaths, and a recovery time that’s had more ups and downs than a third-rate reality show!
The Down and Dirty Details
Since our last “Disease Outbreak News” update on November 1 (and if you missed that, shame on you!), things have been relatively quiet! As of November 8, 2024, we’re still sitting at 66 confirmed cases which, for clarity, means a case fatality ratio (CFR) of about 23%. And brace yourselves, 68% of the unfortunate victims are chaps, with a significant chunk falling between the ages of 30 and 39. Apparently, Marburg discriminates based on age and… well, gender.
Now here’s a stunning statistic that reiterates the importance of healthcare workers on the frontline: a whopping 80% of confirmed cases come from just two hospitals in Kigali! Now, if you thought your job was tough, try explaining Marburg to a patient while dodging a wave of panic and keeping calm as a cucumber. Hats off to those brave souls!
The 42-Day Countdown & WHO’s Backing
So, what’s with this 42-day countdown? Well, that’s double the maximum incubation period of the Marburg virus. No new infections since October 30, and no new deaths since October 14! Fingers crossed that remains the case.
As for the WHO (World Health Organization for those who’ve been living under a rock), they’re giving Rwanda some serious support, reinforcing surveillance and infection control measures like they’re prepping to win the Olympics. Let’s face it; the only gold medal we need is a virus-free country!
How Does Marburg Even Work?
Ah, the science bit! Marburg virus belongs to the same tantalizing family as Ebola – splendid, right? Symptoms appear within 2 to 21 days, usually starting with a delightful mix of high fever, headaches, and malaise. Then it goes downhill faster than a kid on a slippery slope, featuring cramps, nausea, and the whole shebang!
In fatal cases, hang tight for the drama: patients often experience severe blood loss and shock, usually succumbing to the virus within a week. In terms of treatments, it’s a bit of a waiting game, as there are currently no approved vaccines. Isn’t viral fun just grand?
Public Health Response – The Struggles of an Unsung Hero
- Rwanda is coordinating a response worthy of a soap opera; with WHO by their side, they’re deploying surge teams with superhero capabilities!
- These “surge teams” are involved in everything from epidemiology to health logistics! Honestly, I can barely coordinate a meeting, and they’re out there saving lives!
- WHO is ensuring that health workers are armed with the information they need, running training programs that sound like they’d wind up on reality TV.
- And yes, proper waste management is being enforced – no one likes to deal with contaminated surfaces!
WHO’s Risk Assessment: The Elementary Approach
In true bureaucratic fashion, the WHO’s risk assessment reads like a manual on how not to contract a virus. Marburg is tricky to diagnose in its early days but is definitely not as contagious as you might think; it usually requires close contact with infected bodily fluids. So, a bit of advice: keep your distance from anyone with mild flu symptoms and definitely from those with bleeding!
Community Engagement: Because Why Not?
Community participation is a key player in this saga. WHO encourages locals to be vigilant about their health and understand the risks associated with human-to-human transmission. Sounds like classic “It Takes a Village,” doesn’t it? Raising awareness about Marburg will help keep the infection at bay. Remember, a well-informed public is a healthy public!
The Road Ahead: Optimism Is Key!
As we brace ourselves for the finish line, let’s take a moment to appreciate the work being done behind the scenes to end this outbreak. The call for no travel or trade restrictions with Rwanda is a breath of fresh air, allowing life to carry on as normal while keeping safety a priority.
This cheeky summary of the Marburg virus situation in Rwanda takes various aspects of information from the provided article and presents them in a conversational and engaging format, with a touch of humor reminiscent of the mentioned comedians, while keeping the serious nature of the topic in mind.
Walk in the park when it comes to severity. Given the current situation in Rwanda, where proactive measures are being taken to ensure public safety, the WHO has classified the risk of regional spread as moderate. This indicates that while the situation is under control, vigilance is still paramount.
### Key Recommendations Moving Forward
As the countdown to potentially declaring the Marburg outbreak over proceeds, the focus is on several critical areas to maintain safety and prevent resurgence:
– **Ongoing Surveillance**: Continued monitoring for any new cases or potential spillovers is essential. The public health teams are advised to keep a close eye on not just symptomatic individuals, but also on anyone who might have been in contact with confirmed cases.
– **Data Sharing**: Countries are urged to share genomic sequencing data to better track the virus’s evolution and transmission dynamics. This collaborative effort can greatly aid in future responses and understanding the disease.
- **Capacity Building**: Investing in robust healthcare infrastructure, especially at border points, is crucial. This ensures that if the virus crosses borders, there will be immediate readiness to manage new cases.
– **Support for Healthcare Workers**: Given that a large percentage of cases stem from healthcare environments, bolstering support and training for healthcare workers is paramount to reduce infection risks among this vulnerable group.
– **Community Engagement**: Raising awareness about Marburg virus disease (MVD) within the community can lead to better self-reporting and adherence to health directives. Information campaigns can help dispel myths and educate about symptoms and preventive measures.
### Resources for Further Information
