(1/16) However, I don't follow the argument that the guidance has changed because of new evidence. The evidence has been there all along. I have a few comments on the most recent review in the Lancet

Suppressing COVID-19 transmission in Hong Kong: an observational study of the first four months researchsquare.com/article/rs-340…

(1/10) Just posted our new preprint on the successful suppression of first wave of #COVID19 in Hong Kong with Gabriel Leung researchsquare.com/article/rs-340…

The debate about 1 metre or 2 metres is missing the point. What matters is combination prevention—physical distancing (minimum 1 metre, more if you can), hand washing, respiratory hygiene, face masks in enclosed spaces, and avoid mass gatherings. 2 metres is no magic bullet.

Hong Kong Citizen News have kindly agreed to publish my commentary on herd immunity. It's a long read, available here, grab a coffee: hkcnews.com/article/39405/… I published a similar commentary a few weeks ago in Chinese in Mingpao. I'll give a short summary in a new thread below

I’ve been seeing some misinformation locally about Delta mortality rates in vaccinated versus unvaccinated individuals, based on this recent report from Public Health England (1/13) assets.publishing.service.gov.uk/government/upl…

I just had the opportunity to present on fractionation at the WHO consultation on COVID-19 vaccines research, based on the commentary I wrote with Wey Wen Lim and Sarah Cobey who.int/news-room/even…

This is very nice!

Laila Shahrokhshahi Would recommend third dose asap for persons who are older or who have underlying medical conditions, or who are planning to travel internationally I imagine some ppl who don’t fit into any of those categories might choose to defer third dose for a while, with current risk level

How do the antibodies from people infected with different VOCs react to all of the other VOCs, including Omicron? Exciting new work with Karlijn van Straten, Marit van Gils 👩🏻‍🔬🦠🧬🔬 Dirk Eggink @AlvinXHan, Rogier Sanders, and many others - medrxiv.org/content/10.110…

What do I mean when I say “endemic” transmission? Roughly, the use of this term falls into one of two camps: “self-sustaining transmission” or “regular and predictable transmission”. The former is the more public health definition, the latter is the more math definition. A 🧵

The coming weeks (and months) are going to be very hard on Hong Kong's most in need. If you have a few spare coffee coins floating around - feedinghk.org/bridge-the-gap…

Recently published, and brace yourself for the spine tingling horror of this AMR: Emergence of dual and multicarbapenemase coproducing organisms in the United States cup.org/3HKW0gs

I'm so excited our paper on reducing the emergence of antibiotic resistance during treatment is finally out in Science Magazine!!! Roy Kishony @idanyelin science.org/doi/10.1126/sc…

When most of the world relaxes covid restrictions, what should we expect from influenza epidemics? Has the lack of influenza over the last two years set us up for a flu mega-epidemic? We try to answer this in a new preprint - medrxiv.org/content/10.110…

About 600 (and counting) nursing homes have so far recorded test positive cases, amongst residents and/or staff.

So vax rates by age are better understood like this, with bars sized according to each age group’s baseline mortality risk. That is a helluva lot of red, unvaxxed people. And in Zero Covid countries there are no prior infections, so these people are completely immuno-naive.

* Viruses do not automatically evolve to become less virulent. That is a myth. What is under selection is transmission and/or immune escape. Virulence is secondary. * The landscape in which the virus evolves is changing host immunity and behaviour change.

Here is the summary of our findings. There are many implications for diagnosis and therapy for #longCOVID. (26/)
