Many commentators discuss Andes virus on MV Hondius with reference to the entire genus of hantaviruses that causes diseases in humans. This is an egregious error, equivalent to discussing SARS-CoV-2 with reference to the entire genus of betacoronaviruses.

An insanely counterproductive message. Tells any US health workers that if they get infected trying to contain the outbreak, they won't be allowed home. In the 2014 outbreak we did the opposite, because we knew that posture would undermine the response and extend the outbreak.

@RogerSeheult The other thing that happens in an outbreak with high mortality. Heroic healthcare workers and volunteers, mostly local, stand their ground, and pay the price. afro.who.int/news/last-ebol… See also "Fever, Feuds and Diamonds", by the late Paul Farmer.

And this is exactly what I've been saying happens in a pandemic with 40+% mortality. Everything breaks down. Anarchy. People not getting things. They are setting fire to the hospital (the last place you would want to set a fire to). Supply chains break fast. You need to have rational thinking and backup plans to supply-chain dependent medical interventions. Some people think that government mandates are the thing to fear in another pandemic. It's not overbearing law enforcement but rather lawlessness.

#ALERTE 🚨 : Tentative d’intrusion à l’hôpital de Rwampara « Nous sommes actuellement enfermés à l’hôpital de Rwampara. Des manifestants tentent de récupérer de force les corps des personnes décédées d’Ebola. Ils commencent également à incendier certaines installations de l’hôpital. La situation est extrêmement tendue et nécessite une intervention urgente des autorités compétentes afin de sécuriser les patients, le personnel médical et les infrastructures sanitaires », explique une source sur le lieu.

@BarryHunt008 The time was wasted and gone, a long time ago. Just as it was in 2014. And just as in 2014, it will come down to a handful of heroic healthcare workers, mostly local, who will stand their ground in the face of death. Honour is due. apnews.com/article/aa7a12…

@jakescottMD Ebola is a disease of poverty, violence and corruption. It will not spread beyond Africa, simply because the word "Ebola" evokes so much fear that rich countries like the US will take extraordinary measures to keep it out, and to truly isolate cases and suspected cases.

Jake Scott, MD@jakescottMD·11h

Robert Redfield predicting a “very significant pandemic” from this Ebola outbreak misstates the basic epidemiology. Filoviruses spread through direct contact with bodily fluids from symptomatic patients; even the 2013–16 West Africa outbreak that killed ~11,300 people remained a regional epidemic. Cross-border spread is a real concern worth preparing for, but pandemic is the wrong word.

@DrFiliatrault They want to encourage prospective mothers to schedule births at more convenient times, instead of just waiting til the last minute.

English

Dr. Lyne Filiatrault@DrFiliatrault·12h

A very good question! “On the Fraser Health Facebook page, a person asked: ‘…is there a solution in sight or is this just the new norm now, that it’s acceptable to be closing multiple hospitals to births every Thursday till Tuesday for eternity?’”

Lots of AI imagery around now, a really big change since past virus outbreaks I've watched from the social media sidelines. I try to make graphics that are 'mine' but there are certainly easier & faster ways to make infographics than the stupidly intensive hands-on way I do it!

@KrutikaKuppalli @MackayIM How should phlebotomists and lab techs in an Ebola Treatment Unit be protected from infection?

English

Krutika Kuppalli, MD FIDSA@KrutikaKuppalli·1d

As someone who ran an #Ebola Treatment Unit during the 2014 West Africa outbreak, I’m honestly not sure what an “Ebola response clinic” is supposed to mean. When Ebola is suspected, patients need rapid isolation and high-quality supportive care — IV fluids, oxygen, pain control, monitoring — ideally in a dedicated treatment center with trained staff, proper IPC infrastructure, laboratory support, and the workforce required to safely run these facilities 24/7. state.gov/releases/offic…

@JonLemire Maybe @theatlantic could add this bit: Ebola outbreaks emerge from the ongoing mini-wars in DRC that are fuelled by extraction/theft of mineral resources, to the misery of the people who live there, and the benefit of outsiders. @siddharthkara npr.org/sections/goats…

Wow. This graph puts the speed of this outbreak into context. It's not an illusion. This is *very fast*. 👀 x.com/i/status/20569…

The early trajectory of the Ebola outbreak in DRC is alarming. Spread of the disease likely went undetected for months. Fast detection and response are crucial to stop outbreaks.

@angie_rasmussen So lab techs handling clinical samples of Lassa/Ebola do not require safe working conditions?

Dr. Angela Rasmussen@angie_rasmussen·1d

@danwalker9999 That is ONE guy with an opinion. Kind of like you, except also not because Boisen does have expertise & knows Lassa virus is not Ebola virus. He is describing conditions for handling clinical samples, not doing pathogenesis studies.

Literally no Ebola expert ever said “less PPE is better”. Workers were forced to wear surgical masks because they didn’t have access to respirators. They are forced to do so again because USAID cut funds, not because of this silly invented controversy

Raina MacIntyre@Globalbiosec

Transmission of #Ebola is being debated yet again. In the catastrophic West African epidemic in 2014, health workers were forced to work in surgical masks and many got infected. Medical journals refused to publish us, instead, publishing articles saying "less PPE is better". A nursing journal published us, because #nurses are at the frontline 1/2 sciencedirect.com/science/articl…
