Even as Cyclospora outbreaks have become more frequent, CDC's parasite surveillance team was slashed from 11 people to 3 last year. Joel Barratt, who ran the team, tells me he worries the agency doesn't have the staffing to stop the current outbreak quickly. My story in @nature.com:

‘Explosive diarrhoea’ outbreak grips US: how researchers are hunting its source

Cases have hit record levels, and scientists are racing to pinpoint where the Cyclospora parasite entered the food supply.

A year after global #HIV funding was upended, CHAI finds: ⬇️ 42% fewer people started oral HIV prevention in 10 countries ⬇️ 5.8M fewer HIV tests run in 8 countries ⬇️ 39K fewer adults started on treatment in 8 countries ⬇️ 26K fewer children on treatment in 9 countries Details here: ow.ly/J2ig50Z8Rzt

'We're not seeing a rebound': New data shows HIV services not recovering

New research from the Clinton Health Access Initiative shows declines in HIV testing and in people accessing oral prevention services.

“This crisis didn’t happen in a vacuum. When you pull billions out of the WHO and dismantle frontline USAID programmes, you gut the exact surveillance system meant to catch these viruses early. We are seeing the direct, deadly consequences of treating global health security as an optional expense.”

Infectious diseases such as hantavirus and Ebola becoming more frequent and damaging, say experts

Pandemic report warns of growing global threat as health teams in Africa move to contain Ebola outbreak

While everyone is watching hantavirus I'm actually much more eager to learn more about the Ebola outbreak in DRC's Ituri Province that Africa CDC has confirmed. Early information makes it sound very large for an outbreak that has just been reported: "about 246 suspected cases and 65 deaths"

The title says it all. I'll add that this is entirely self-inflicted and will get much worse as the consequences compound in the years to come. "Hantavirus misinformation runs rampant as the US is unequipped to respond to infectious disease health scare" www.theguardian.com/science/2026...

Hantavirus misinformation runs rampant as the US is unequipped to respond to infectious disease health scare

But the US’s withdrawal from the WHO – and cuts to the country’s health system – stymie officials’ response

I've spent yesterday and today talking to researchers across the globe trying to understand the hantavirus outbreak aboard the cruise ship MV Hondius. My story in @science.org is here (and some threaded thoughts coming): www.science.org/content/arti... 🧪 #IDsky

Nearly 780 people die every day in Europe from liver disease—a largely preventable crisis. A new report from the EASL–Lancet Commission calls for urgent policy action to tackle Europe’s rising liver disease burden: spkl.io/63326AfOqr

Part of a Lancet infographic showing the mortality rate for liver cancer and cirrhosis between 2000 and 2023.

More than half of participants in a small HIV cure trial maintained a low enough viral load to stay off treatment for 20 weeks. One participant remains undetectable after a year. Note: while this is encouraging, the different responses indicate the prospect of a cure for all remains distant.

Half the participants from placebo arm of HIV cure trial have prolonged viral load remission when given broadly neutralising antibodies

In the second phase of the RIO HIV cure trial, participants originally given a placebo were offered the experimental therapy, the Conference on Retroviruses and Opportunistic Infections (CROI 2026) he...
