The Government of Tanzania has officially declared the end of the Marburg Virus Disease (MVD) outbreak in Kagera Region, following 42 days without any new reported cases.

Health Minister Jenista Mhagama made the announcement on March 13, 2025 in Biharamulo District, Kagera Region, stating that the country has met the World Health Organization (WHO) criteria for declaring the end of an outbreak. The last confirmed MVD case was reported on January 28, 2025.

The outbreak, which was first declared by President Samia Suluhu Hassan on January 20, 2025, saw two confirmed cases, both of whom tragically lost their lives while receiving treatment. Marburg Virus Disease is a severe and often fatal illness, transmitted through direct contact with body fluids of an infected person.

Minister Mhagama commended the swift and coordinated response led by the government in collaboration with various stakeholders, including healthcare workers, social welfare officers, nutritionists, and community health workers. She acknowledged the technical and financial contributions from local and international partners, as well as the dedicated efforts of responders at all levels.

Special recognition was given to the Ministry of Health’s technical team, led by Permanent Secretary Dr. Seif Shekalaghe, along with Chief Medical Officer Dr. Grace Magembe and officials from regional and district health authorities.

Despite successfully containing the outbreak, the Minister urged Tanzanians to remain vigilant against infectious diseases, emphasizing the importance of maintaining hygiene practices such as handwashing and promptly reporting any unusual health events. She warned that Tanzania remains at risk of other highly infectious diseases, including Ebola, which has been reported in neighboring countries, and Mpox, which has also affected Tanzania recently.

"The government will continue taking all necessary measures to protect its citizens and the international community from health threats," Minister Mhagama assured.

Citizens are encouraged to report any health concerns through the toll-free hotline 199 or by visiting the nearest health facility.

Uganda is currently grappling with a new cluster of Ebola cases, as reported by the Africa Centres for Disease Control and Prevention (Africa CDC) on March 6, 2025. This recent development includes three confirmed and two probable cases, spanning five districts. Since the outbreak's onset in January, the total number of cases has risen to 14, with two confirmed fatalities. 

The outbreak was initially declared following the death of a male nurse in Kampala. Subsequently, a four-year-old child also succumbed to the virus. Notably, the new cluster does not have a direct epidemiological link to the initial group of nine cases, indicating possible new transmission chains. 

The World Health Organization (WHO) has confirmed the increase in cases and is actively supporting Uganda's response efforts. This includes deploying experts, providing training in contact tracing, testing, patient care, and delivering essential medical supplies. 

In response to the outbreak, the United Nations has launched an emergency appeal for $11.2 million to support Uganda's efforts in containing the virus and mitigating its socio-economic impact across seven high-risk districts. 

Currently, there are no approved vaccines for the Sudan strain of the Ebola virus responsible for this outbreak. However, Uganda has initiated a trial vaccination program to assess potential candidates. 

Efforts are being intensified to monitor and trace contacts, and communities are being engaged to enhance public awareness and encourage early reporting of symptoms. Despite these measures, challenges remain, particularly in surveillance and contact tracing, as evidenced by the recent cases without clear links to known contacts. 

Uganda has a history of effectively managing Ebola outbreaks, including the 2022 outbreak that resulted in 55 deaths out of 143 infected individuals. The experience and systems built from past outbreaks are being leveraged to address the current situation. 

In February Uganda had announced that all eight patients who had been hospitalized for treatment have been discharged after testing negative twice for the virus in tests conducted 72 hours apart. The World Health Organization (WHO) regional office for Africa confirmed the development, describing it as an important step in controlling the outbreak.

The patients had been receiving treatment in the capital city, Kampala, and in Mbale. Despite their discharge, health officials continued to monitor 216 to 265 individuals who remained in quarantine due to potential exposure. Uganda’s Health Minister, Jane Ruth Aceng Ocero, confirmed the recovery of the eight patients and urged communities to welcome them without stigma.  If no new cases had been confirmed in the next 42 days, the outbreak could have been declared over.

The Tanzanian Ministry of Health has confirmed two cases of Mpox (Monkeypox) in the country. In a public statement released on March 10, 2025, the Ministry detailed that on March 7, 2025, it received reports of individuals exhibiting symptoms such as facial, hand, foot, and body rashes, accompanied by fever, headaches, sore throat, and muscle and back pain. Among these individuals was a truck driver who had travelled from a neighbouring country to Dar es Salaam. Laboratory tests conducted on March 9, 2025, confirmed that two individuals were infected with the Mpox virus.

In response, the Ministry, in collaboration with the President's Office – Regional Administration and Local Government (TAMISEMI) and all health service centers, is actively monitoring, investigating, and identifying any additional suspected cases to provide appropriate care. Mpox is primarily transmitted from animals, particularly primates, to humans through direct contact with infected animals, their fluids, or meat. Human-to-human transmission can occur through direct contact.

The Ministry advises the public to take the following preventive measures:

Seek immediate medical attention at health facilities upon noticing any Mpox symptoms or call the toll-free number 199.

Avoid sharing personal items such as clothing and bedding with individuals showing Mpox symptoms.

Refrain from physical contact, including handshakes, kissing, hugging, or sexual intercourse, with symptomatic individuals.

Avoid contact with bodily fluids of those exhibiting Mpox symptoms.

Do not care for individuals with Mpox symptoms without taking necessary precautions.

Health workers should consistently adhere to infection prevention protocols when treating patients, especially those with rashes and fever.

Regularly wash hands with running water and soap or use hand sanitizers.

The Ministry assures the public that the government is prepared to control the spread of Mpox, leveraging its experience in managing outbreak diseases. Efforts are underway to strengthen disease surveillance at all levels, enhance screening at national borders, and promote public health education to empower citizens to take preventive actions.

Additionally, the Ministry provided an update on the Marburg virus outbreak, noting that as of March 10, 2025, 41 days have passed without any new cases. The public is encouraged to continue their daily activities while adhering to the recommended preventive measures against Mpox.

In a significant milestone in Uganda's fight against the Ebola Sudan virus, all eight patients who had been hospitalized for treatment have been discharged after testing negative twice for the virus in tests conducted 72 hours apart. The World Health Organization (WHO) regional office for Africa has confirmed this development, describing it as an important step in controlling the outbreak.

The patients had been receiving treatment in the capital city, Kampala, and in Mbale. Despite their discharge, health officials continue to monitor 216 to 265 individuals who remain in quarantine due to potential exposure. Uganda’s Health Minister, Jane Ruth Aceng Ocero, confirmed the recovery of the eight patients and urged communities to welcome them without stigma.  If no new cases are confirmed in the next 42 days, the outbreak can be declared over.
 

A lower fatality rate compared to previous outbreaks

The outbreak, which began in late January, marked Uganda’s first Ebola Sudan outbreak since 2022 and the world's ninth recorded instance of the virus. Historically, Uganda has experienced eight Ebola outbreaks since the first recorded case in 2000.

The outbreak has resulted in a total of nine cases and one death, which involved the index patient, a 32-year-old male nurse who worked at a referral hospital in Kampala. The case-fatality rate (CFR) stands at 11.1%, significantly lower than previous outbreaks, where the CFR ranged between 41% and 100%.

The Sudan strain of the Ebola virus is a highly infectious hemorrhagic fever transmitted through direct contact with infected bodily fluids and tissues. Unlike the more common Zaire strain, there is currently no approved vaccine for the Sudan strain. However, Uganda responded swiftly to the outbreak by launching a trial of a candidate Ebola Sudan vaccine earlier this month.

Swift response from health authorities and partners

Uganda’s response to the outbreak has been supported by various health organizations, including the WHO, which deployed 47 experts and delivered seven tons of emergency medical supplies to aid the country’s efforts. WHO Representative in Uganda, Dr. Kasonde Mwinga, emphasized that while the discharge of the patients is a positive development, efforts to completely halt the outbreak are ongoing.

The WHO reiterated that the Sudan strain of Ebola is severe, typically killing at least 40% of those infected, making the lower fatality rate in this outbreak a notable success.

Tanzania is expected to experience unusually heavy rainfall in its central to southern regions between February 4 and 11, 2025. At the same time, the Greater Horn of Africa (GHA) region will likely see warmer-than-average temperatures, according to the latest weather forecasts from the IGAD Climate Prediction and Applications Centre (ICPAC).

During this period, moderate rainfall ranging between 50 and 200 millimeters is expected across most parts of Burundi and central to southern Tanzania. In contrast, northern Tanzania and most parts of Rwanda are likely to receive light rainfall of less than 50 millimeters. It is important to note that one millimeter of rainfall is equivalent to one liter of water per square meter.

Rainfall anomalies indicate that central to southeastern Tanzania will receive more precipitation than usual, whereas the western regions of the country will experience lower-than-normal rainfall. Some areas in the central to southern regions may see exceptional rainfall amounts exceeding the top 10% of recorded levels. This raises concerns about potential flooding, particularly in flood-prone areas, where residents should remain vigilant and stay updated on weather alerts.

The temperature forecast for the same period suggests that moderate to high temperatures, ranging between 20 and 32 degrees Celsius, will prevail across South Sudan, Uganda, Tanzania, Kenya, Somalia, Djibouti, Eritrea, central to southern Sudan, and the eastern parts of Rwanda and Burundi. Meanwhile, milder conditions, with temperatures below 20 degrees Celsius, are expected in northern Sudan, the Ethiopian highlands, northern Somalia, and parts of central to western Kenya.

Temperature anomalies point to warmer-than-usual conditions across most of the GHA region, with some areas in southeastern Kenya and isolated parts of the region experiencing cooler-than-normal temperatures. Additionally, extreme cautionary heat stress levels are anticipated in South Sudan, southern Sudan, eastern Tanzania and Kenya, and southern Somalia. See weather maps here .

Uganda’s Ministry of Health has confirmed an outbreak of Sudan Ebola Virus Disease (SVD) in Kampala following laboratory confirmation from three National Reference Laboratories. The index case, a 32-year-old male nurse from Mulago National Referral Hospital, succumbed to the disease after presenting severe symptoms.

Details of the index case

The deceased, who worked at Mulago National Referral Hospital, initially exhibited fever-like symptoms and sought treatment at multiple health facilities, including Mulago, Saidina Abubakar Islamic Hospital in Matugga, and Mbale Regional Referral Hospital in Mbale City. His condition deteriorated, leading to unexplained bleeding from multiple body sites, multi-organ failure, and ultimately death on January 29, 2025. Post-mortem tests confirmed the presence of Sudan Ebola Virus Disease.

Government response and preventive measures

The Ugandan Ministry of Health has taken swift action to contain the outbreak:

Incident management team activated: Rapid Response Teams have been dispatched to Mbale City and Saidina Abubakar Islamic Hospital in Matugga to monitor and control the situation.

Contact tracing underway: A total of 44 contacts have been identified, including 30 health workers and patients from Mulago, 11 family members of the deceased, and four health workers from Saidina Abubakar Islamic Hospital.

Safe burial practices: The deceased will be accorded a safe and dignified burial to prevent further transmission.

Vaccination rollout: Immediate vaccination of all identified contacts is set to commence to curb the spread of the disease.

Background on Ebola in East Africa

Ebola Virus Disease (EVD) has been a recurring threat in East Africa, with Uganda experiencing multiple outbreaks over the years. The Sudan Ebola Virus strain, which differs from the more common Zaire strain, has a high fatality rate but currently lacks an approved vaccine. The most recent outbreak in Uganda occurred in 2022, leading to significant public health interventions.

Understanding Ebola Virus Disease

Ebola Virus Disease is a severe and often fatal illness caused by viruses in the Filoviridae family. It spreads through direct contact with the bodily fluids of an infected person, contaminated surfaces, or infected animals.

Symptoms of Ebola

High fever

Severe headache

Muscle pain and weakness

Sore throat

Vomiting and diarrhea

Unexplained bleeding or bruising

Multi-organ failure in severe cases

Vaccination and treatment

While there is no approved vaccine for the Sudan strain, vaccines such as Ervebo (rVSV-ZEBOV) have proven effective against the Zaire strain. Treatment primarily focuses on supportive care, including:

Hydration and electrolyte balance

Oxygen therapy

Blood pressure stabilization

Experimental monoclonal antibody therapies

Prevention Measures

Avoid direct contact with infected individuals

Proper hand hygiene and use of personal protective equipment (PPE)

Safe burial practices for deceased individuals

Public health awareness campaigns to control outbreaks

Conclusion

The Ministry of Health continues to monitor the situation and will provide regular updates as new developments emerge.

The Tanzania government plans to establish a specialized centre for epidemic disease management in Kagera, northwestern Tanzania, equipped with all essential laboratory facilities for testing high-risk pathogens. Additionally, a healthcare facility will be constructed to enhance access to medical services.

This was revealed on January 29, 2025, by the country’s Deputy Minister of Health, Dr. Godwin Mollel, during his visit to the office of Kagera Regional Commissioner, Hon. Fatma Mwassa, to commend the efforts in controlling the Marburg virus outbreak in Biharamulo District, which the government says has now been contained. With two confirmed cases and 18 suspected cases reported, this marks Tanzania's second encounter with the deadly virus since the 2023 outbreak in the same region.

Dr. Mollel stated that the government recognizes the need for such a centre in Kagera due to its geographical location, as the region borders four neighbouring countries, making it vulnerable to epidemic outbreaks due to cross-border interactions.

Speaking about the healthcare facility construction, he confirmed that funds have already been allocated, and Kagera is among the priority regions. The government's current focus is on strengthening primary healthcare services.

"We need to improve our border health systems, including ensuring that we have committed personnel at all times," said Dr. Mollel. Additionally, he emphasized that the government will ensure that regional security and defense committees receive specialized health training, as they play a crucial role during public health emergencies.

Meanwhile, the minister directed the Medical Stores Department (MSD) to provide regional and district commissioners with copies of medicine distribution reports for hospitals in their respective areas to enhance accountability and monitoring.

He explained that under the current system, medical supplies are directly delivered to hospitals, making it difficult for regional or district leaders to verify medicine shortages when they arise.

 For her part, Kagera Regional Commissioner, Hon. Fatma Mwassa, expressed gratitude to the President of Tanzania, Hon. Dr. Samia Suluhu Hassan, for the swift response in allocating funds to combat the Marburg virus outbreak in the region. She urged the Ministry of Health to continue strengthening the capacity of security and defence committees, border personnel, and staff at the Bukoba and Kemondo ports to ensure efficient response during epidemic outbreaks.

The World Health Organisation (WHO) on 27 December 2024  provided an update on the mysterious disease outbreak in the Panzi health zone, Kwango Province, Democratic Republic of the Congo. Initially reported as an undiagnosed illness on November 29, the outbreak is now identified as a combination of acute respiratory infections and falciparum malaria, compounded by severe malnutrition.

Since the alert, 891 cases and 48 deaths, predominantly among children under five, have been reported across 25 of Panzi’s 30 health areas. Enhanced surveillance has revealed a mix of symptoms including fever, cough, and body weakness, with many cases linked to common respiratory viruses (e.g., Influenza A, SARS-CoV-2) and malaria.

Preliminary findings

Laboratory tests on 430 samples indicate:

• 62% tested positive for malaria.
• 64 samples showed infections with respiratory viruses like Influenza A, rhinoviruses, and SARS-CoV-2.

Severe malnutrition, affecting nearly half the children under five in the area, has exacerbated the impact of these diseases.

Response efforts

Authorities, with support from WHO, Africa CDC, and UNICEF, have intensified their response:

• Surveillance: Active case searching and enhanced data collection continue in affected areas.
• Case management: Health workers are receiving training, and essential supplies, including oxygen concentrators, are being delivered to facilities.
• Laboratory testing: Further virological and bacterial analysis is underway to refine understanding of the outbreak.
• Risk Communication: Public awareness campaigns are being conducted to encourage early care-seeking and preventive behaviors.

Challenges and broader implications

Kwango Province faces a crisis of food insecurity and malnutrition, classified as IPC Phase 3 (Serious) and projected to worsen. Malnutrition weakens immunity, increasing vulnerability to infections and worsening disease outcomes. Limited healthcare access, shortages of medical supplies, and poor infrastructure compound the crisis.

The outbreak highlights the urgent need to:

1. Strengthen healthcare systems and access to treatment.
2. Address food insecurity and malnutrition.
3. Improve surveillance and response capacities in remote, vulnerable regions.

While risks remain localized to Panzi, the event underscores the critical intersection of health, nutrition, and poverty in driving preventable deaths. Continued international support is vital to mitigate the crisis and prevent similar outbreaks elsewhere in the country.
