A fast-spreading Ebola outbreak in the DRC's Ituri province has killed at least 87 people across 246 suspected cases — and experts warn the Bundibugyo strain driving it has no approved vaccine. By One Day MD Editorial Team · Updated May 17, 2026 · 6 min read 87+ Deaths confirmed 246 Suspected cases 13 Lab-confirmed cases 0 Approved vaccines A deadly Ebola outbreak has been confirmed in the Democratic Republic of Congo (DRC), health authorities announced on May 15, 2026 — and it is already spreading beyond the country's borders. At least 87 people have died and 246 suspected cases have been recorded in Ituri province, eastern DRC, making this the country's 17th Ebola outbreak since the virus was first identified there in 1976. What makes this outbreak uniquely alarming is the strain involved. Unlike the majority of Congo's previous outbreaks — which were caused by the well...

Pandemics are not driven by how deadly a virus is — they are driven by how efficiently it spreads, how early it transmits, and how well it evades detection and immunity. This explainer compares Nipah virus, COVID-19 (SARS-CoV-2), Ebola virus, and bird flu (avian influenza such as H5N1 and H7N9) using a systems medicine and preventive health lens . It is designed to answer high-intent search queries such as: Nipah vs COVID vs Ebola vs bird flu Which virus is most dangerous? What is the next pandemic risk? Why some viruses cause pandemics and others don’t The Core Insight: Why Some Viruses Become Pandemics Deadliness alone does not cause pandemics Transmission efficiency outweighs lethality Viruses that spread before symptoms appear dominate globally This framework explains why: COVID-19 reshaped global society Ebola outbreaks remain regional Nipah virus alarms scientists but rarely spreads Bird flu is considered the most credible future pandemic threat Nipah Virus (NiV): High Fatalit...

Return guest Dr. Paul Saladino is a board-certified psychiatrist and also board certified in nutrition. He wrote "The Carnivore Code," which just came out in an updated second edition. In this interview, he discusses the impact metabolic health has on COVID-19 outcomes. He's done a magnificent job explaining the science that supports the natural lifestyle strategies that optimize our immune systems to defeat not only COVID-19, but also most other infectious agents. "The psychiatry was a jump-off point for thinking about how immune function and metabolic health affects mental health," he says. "I quickly realized that everything in the body was connected and I couldn't just focus on the brain without focusing on the rest of the body, and that has led us to where we are today. I think that as we are faced with coronavirus, it's a reminder of the metabolic health and how critical that is. I think so much of the...

A new study adds to 11 others for increased risk of Type 2 diabetes. Back in 2020, when the first signals that diabetes (particularly Type 2) was showing up more than a month out from Covid, the hope was that it was spurious. But then study after study have been confirming this sequela. A new study  (JAMA 2023) from the province of British Columbia in Canada, a comprehensive population assessment, is the 12th report of a heightened risk of Type 2 diabetes after Covid. This cohort was younger than most (mean age 32 years) and the increased risk of 17% was less than most of the previous publications. I’ve summarized the key data for Type 2 diabetes risk in the Table below. As you can see, the cohorts varied considerably with respect to age and sex. Consistently, the risk has been seen to be higher in men, in people of advanced age, and among those obese, and those with severe Covid. The increased risk compared with controls ranges widely from 17% to 97% with only 1 of these studies ...
