To celebrate 100 years of insulin- one of my favourite venomous creature facts. The cone snail releases venom containing fast acting insulin into the water to catch its prey. It’s amazing. Take a look! bit.ly/32eV5lt

I congratulate the government and people of #Kenya on the elimination of human African trypanosomiasis or sleeping sickness. Kenya joins the growing rank of countries freeing their populations of sleeping sickness, and bringing Africa one step closer to being free from neglected tropical diseases!

Le #ClycloneChido🌀 a affecté environ 45 000 personnes dans le sud et le centre du #Malawi🇲🇼. Six centres de santé ont été endommagés, entraînant des pertes de fournitures médicales. Pour soutenir les efforts des autorités sanitaires, @WHO a déployé des premiers intervenants au Centre national des opérations d'urgence à Blantyre et dans les districts touchés.

An extraordinarily strong lesson on the importance of good science, critical thinking, and being truly objective. The damage done to trust and to patients by the hydroxycholoroquine debacle should never be repeated. Would love to know the reasons for retraction.
Extraordinary: Raoult’s damaging paper on hydroxychloroquine for COVID-19 finally retracted. So grateful to all the people who helped with the RECOVERY trial, allowing us to debunk the myth of hydroxychloroquine for severe COVID-19 science.org/content/article/…

Good news stories in global health don’t get as much coverage as the failures. We should all take a moment to congratulate Rwanda for how they’ve managed this outbreak to date. This piece is a great summary of where things stand with Marburg in Rwanda 👇 npr.org/sections/goats-and-s…
