We should let Americans come back Report if they had exposures. Monitor for symptoms. Get care if they need it. We can keep everyone else safe without shooting ourselves in the foot End

During every past Ebola outbreak, the US has treated exposed citizens in state-of-the-art facilities. That has saved lives. This harsh action will risk the health and lives of Americans. It will also discourage health workers from assisting in the Ebola response.

Africa is standing united against the ongoing Bundibugyo Ebola Virus. Today, during the High-Level Ministerial Meeting, governments and partners announced approximately US$498.8 million in pledges and commitments to strengthen response efforts across affected and high-risk countries. This is a powerful demonstration of African solidarity, leadership, and collective responsibility in protecting our continent’s health security. As the outbreak evolves in a complex environment, trust, coordination, and rapid action remain essential to stopping transmission and saving lives. I thank our Member States, partners, and frontline responders for rising together at this critical moment for Africa’s Health Security. ------ L’Afrique reste unie face à l’épidémie en cours du virus Ebola Bundibugyo. Aujourd’hui, lors de la Réunion ministérielle de haut niveau, les gouvernements et partenaires ont annoncé environ 498,8 millions de dollars américains en promesses et engagements afin de renforcer les efforts de riposte dans les pays touchés et à haut risque. Ceci représente une démonstration forte de la solidarité africaine, du leadership et de la responsabilité collective pour protéger la sécurité sanitaire de notre continent. Alors que l’épidémie évolue dans un contexte complexe, la confiance, la coordination et une action rapide demeurent essentielles pour interrompre la transmission et sauver des vies. Je remercie nos États membres, partenaires et intervenants de première ligne de se mobiliser ensemble à ce moment crucial pour la sécurité sanitaire de l’Afrique. #AfricaResponds #DRC #Uganda

More unsettling news: 2 health care workers with uncertain exposure histories confirmed as #Ebola cases in Uganda. If they didn’t care for known cases, they were infected by undetected cases. That said, Uganda has been very effective in battling Ebola in the past.
🚨 @MinofHealthUG has confirmed 2 additional #Ebola cases, bringing the total number of confirmed cases in Uganda to 7. Particularly concerning is that these new cases are healthcare workers in Kampala and unclear if they cared for any of the other known cases. When health workers become infected, it raises concerns about healthcare-associated transmission, exposures in healthcare settings, and the potential for additional undetected contacts.

This is unsettling. The #Ebola confirmed and suspected case count is at 958 already in DRC, with 5 confirmed cases in Uganda. (Uganda doesn’t often disclose suspected case numbers.) This has all the makings of an ugly and protracted outbreak.
🚨 #EbolaRDC | Rapport de situation au 22 mai 2026 L’épidémie d’Ebola continue de faire l’objet d’un suivi renforcé par les autorités sanitaires dans les provinces touchées. 📍 3 provinces concernées : Ituri, Nord-Kivu et Sud-Kivu 📊 83 cas confirmés et 746 cas suspects cumulés ⚠️ 11 zones de santé touchées 📞 Numéro vert officiel gratuit : 151 Le respect des mesures de prévention et la vigilance collective demeurent essentiels pour limiter la propagation du virus. #StopEbola #PréventionEbola #SantéPublique #Com_MediasRDC

Helen is right. These numbers are staggering, and they are likely to rise quickly given the lag in detecting transmission early in the outbreak. We are chasing far behind this #Ebola outbreak now. Bringing it under control will require major resources, coordination, and sustained effort.

2. The numbers of #Ebola cases in this outbreak are staggering, given it was only declared last Friday. 51 confirmed cases, almost 600 suspected cases & 139 suspected deaths. This is the 3rd largest outbreak on record. Modelers are suggesting a worst case scenario of 1,000 cases; seems optimistic.

Very important points on the importance of local health care workers and community trust in controlling this rapidly expanding #Ebola outbreak below. 👇
The most important thing to know about the Ebola epidemic in DRC is this: bringing it under control will rely almost entirely on health workers winning the TRUST of local communities. This may sound dull, even woke, when compared to talk of experimental vaccines etc. But it’s true, not to mention hugely difficult, resource intensive and dangerous. The logic is this: you have one of the most frightening infectious diseases spreading in a huge uneducated population that has been subjected to horrific poverty and violence for many years. Yet there are no vaccines or special treatments. The only way to stop it is to break the chains of transmission and this requires the full cooperation of the population. Winning trust won’t be easy. More than 2m have been displaced by a conflict that has frequently been marked with mass rapes and village massacres — violence that seemingly occurs without rhyme or reason. There is no understanding of science or politics, and superstition and paranoia understandably fill the gap. This is what hundreds of local health workers employed by the Red Cross, WHO, MSF and others are walking into. To slow and eventually end the outbreak they must convince people with symptoms to come forward so they can be isolated away from their families and treated by people clad head to toe in PPE. Even in death, of which there will be much, they must explain that victims must be separated from their loved ones and forego burial and grieving rites that are central to their faith and understanding. When we think about the Ebola outbreak in DRC we should think about what we would do in such a situation. How we would win the trust of terrified families were we charged with doing so. We should think too about the resources that are needed to pay for and support those putting their lives on the line on our behalf. As things stand, the money needed for the emergency response is only about 40% funded and yet it must last for many months, probably years, if the epidemic is to be successfully brought under control.

Very important point 👇
Just to add an additional reflection that I don’t think gets discussed enough. There’s a tendency to focus on deaths and CFR. This is an excruciatingly horrible disease whether one survives or succumbs, and one with long-term health impacts that are often not supported

Very glad to see @DrTedros act swiftly to declare the #Ebola outbreak in #DRC and #Uganda a #PHEIC. This makes good sense given what we know so far. Large numbers of suspected cases before confirmation, cross-border spread, delayed recognition due in part to diagnostic limitations, a highly mobile population, conflict in the region, and the need for intensive international coordination all fit the criteria for a Public Health Emergency of International Concern. This is a big step in mobilizing resources and facilitating coordination that is critical to getting this outbreak under control.

Ebola is no stranger in the Democratic Republic of the Congo, which has seen more than a dozen outbreaks since the virus was first identified there 50 years ago. But a new outbreak announced by the Ministry of Health has raised more red flags than usual. The ministry says there are already 246 suspected cases, including 80 deaths, in the remote province of Ituri, suggesting the virus spread widely before it was identified. The virus is a rare species called Ebola Bundibugyo, which standard field tests often miss, and for which no vaccines and therapeutics exist. scim.ag/42A38se

HHS reports one American PCR positive for Andes virus with no symptoms mentioned, apparently asymptomatic. Before drawing conclusions, we need to ask: Is this pre-symptomatic infection with active viral shedding? A true asymptomatic case? Or could this be a false positive? The 'mildly positive' language raises questions. All three are scientifically plausible. All three have different implications for how we understand #AndesVirus transmission. #Hantavirus

HHS through @ASPRgov and @CDCgov is supporting @StateDept in the repatriation of 17 American citizens from the MV Hondius cruise ship affected by the Andes variant of hantavirus. All 17 are currently en route via @StateDept airlift to the United States, with two of the passengers travelling in the plane's biocontainment units out of an abundance of caution. One passenger currently has mild symptoms and another passenger tested mildly PCR positive for the Andes virus. As of now, the airlift will transport passengers to the ASPR Regional Emerging Special Pathogen Treatment Center (RESPTC) at the University of Nebraska Medical Center/Nebraska Medicine in Omaha, Nebraska before taking the passenger with mild symptoms to a second RESPTC at its final destination. Upon arrival at each facility, each individual will undergo clinical assessment and receive appropriate care and support based on their condition.
