A Rare Hantavirus Strain Is On The Rise
The WHO has confirmed that eight passengers aboard the MV Hondius have been linked to a suspected outbreak of the Andes strain of hantavirus. Three people have died, and roughly 150 passengers remain on the ship as it sails toward the Canary Islands. Investigators believe the initial infection began with a couple who contracted the virus while bird-watching in Argentina before the boarded the ship.
What makes this strain different? Most hantaviruses are considered dead-end infections, meaning someone who catches it from rodent droppings can’t pass it on. The Andes strain is the rare exception; scientists estimate fewer than 300 cases of human-to-human transmission have ever been recorded. Even the window of infectiousness appears to be short — roughly a day. During that window, transmission can happen during a brief contact. Researchers want to sequence the full genome of the virus to determine where it originated and whether it has developed new mutations.
For the readers: Hantavirus is incredibly severe, with a fatality rate of up to 40%. The virus is classified as a priority pathogen with the potential to spark public health emergencies. The WHO currently considers the international threat low. What to know about hantavirus symptoms and risk factors.
In Brief: Health & Science
🗞️ CNN found a series of deleted tweets from Trump's new surgeon general nominee Dr Nicole Saphier criticizing the administration's health policies. These included suggesting the White House was hiding the US losing its measles elimination status until after the midterms, calling RFK Jr.'s vaccine advisory overhaul “chaos”, and mocking Trump and Elon Musk as “petty, loud, and obnoxious”.
🗞️ An international online platform called Made-in-China has settled with Connecticut's attorney general and agreed to stop selling GLP-1 weight-loss drugs to US customers without prescriptions. The platform had marketed fake generic versions of the drugs that contained impurities and inconsistent ingredient quantities. To be noted: There are currently no generic GLP-1 injections on the market.

❤️ Good News, Exercise Doesn't “Use Up” Your Heartbeats
There's a persistent myth that exercise wears out your heart faster by using up beats. Actually, it’s the opposite if we look at facts. While we average about 2.5 to 3 billion beats over a lifetime, it isn’t a pre-allocated number that eventually just runs dry. In fact, regular exercise strengthens the heart muscle, making it more efficient at rest and lowering your resting heart rate over time, which is why very fit people often have resting pulses of 40 to 50 beats per minute. BBC covers more.
🧠 Is Your Attention Span Actually Shrinking?
It feels so every passing day (thanks, multitasking habits), but there’s a silver lining: your brain's actual capacity for focus hasn't changed much since 1990. Research shows no evidence that the brain's underlying capacity to concentrate has actually declined. In fact, a 2024 meta-analysis of 21,000 people across 32 countries showed slight improvements in adult performance on attention tests. You’re probably asking, “Then why can’t I finish a single paragraph?” Well, that’s because we've become self-interrupters, switching screen tasks every few seconds in search of a quick dopamine hit. Here’s why making that extra effort works in your favor.
🍎 Cardiologists Have Some Advice On ultra-processed foods
The European Society of Cardiology has published a clinical consensus statement urging heart doctors to have more practical conversations with patients about ultra-processed foods. Some simple advice worth noting: cook at home more often, avoid eating late at night, chew more slowly, swap sugary drinks for water, and read nutrition labels before buying anything. Back home, UPFs still constitute about 50% of US diets. Meanwhile, MAHA activists and the current administration have been scrambling to correctly define it.

🥊 The ‘90s Are So Back!
For the uninitiated, Tae Bo brought together the best of martial arts and aerobics, and inevitably dominated every living room in the ‘90s (eyes on you, VHS tapes). So what's it doing on your TikTok For You page decades later? According to The New York Times, Gen Z is fascinated with vintage, equipment-free workouts because that’s all it requires to begin with! Fans also say the rhythmic punching and kicking is an effective grounding tool for managing daily anxiety.
How to start:
You don't need a vintage DVD player. Billy Blanks (now 70 and still “working it!”) has uploaded hundreds of classic and new workouts to social media.
The magic of Tae Bo is the energy. It’s group-driven and vocal. Research backs its effectiveness too, showing that rhythmic movement can significantly lower cortisol.
