We @WHO recognise the tremendous desire to move on from #COVID19, the difficulties to keep fighting & the enormous toll this has taken on our lives.

However, the pandemic will end with our actions & we have the power to take the death and devastation out of COVID.

Short🧵
There are alot of questions about what’s going on with #COVID19 so let’s break it down…

First, #Omicron is still spreading at a very intense level and we are starting to see an increase in cases after a few weeks of decline (this is despite big reductions in testing)
Increasing cases will occur where measures are lifted even in the context of high vaccination coverage—this shouldn’t be a surprise as vaccines are incredibly effective at reducing severe disease and death, but not infections

Note the significant regional differences in trends👇
Omicron (including BA.1 and BA.2) is dominant globally and it is highly transmissible. Among the 430,487 sequences uploaded to @GISAID with specimens collected in the last 30 days, 99.9% were Omicron.
Mortality is still far too high. This is driven by intense spread, low vaccination coverage in at risk groups (eg >60 year olds, people with underlying conditions), gross inequity and lack of access for many across Africa & huge amounts of misinformation. #VaccinEquity @WHO
Even in areas with high population coverage it’s critical to ensure key risk groups reach 100% vaccination coverage. Take a closer look at vaccination rates among >60s in some areas with high mortality during omicron (or delta). Vaccine campaigns need to reach those most at risk.
Here’s the good news: we have tools that can reduce the spread & save lives now. Given all of the tremendous global challenges we face, #COVID19 has solutions

We can save many lives right now & reduce the risk of future variants with access and rational use of life saving tools
Each country is facing a different situation with a unique set of challenges, but the pandemic is not over. We must remain vigilant & continue to vaccinate, test, sequence,care for patients, protect our health workers, ventilate,adapt & adjust population interventions as needed.
We need strong surveillance to detect #SARSCoV2 variants so that globally we can adjust interventions as needed. Now is the time to enhance the systems we put in place for #COVID19, not dismantle them.

We can do this. We must.

(Unsurprisingly) I welcome further studies on the origins of #SARSCoV2

Short thread with initial thoughts on two preprints released yesterday. Bottom line: Keep following the science because many more studies are needed.

1/11
2/ Critical to any understanding of the emergence of a new pathogen are studies of the earliest known and suspected cases. Identifying the first human case of a new disease is EXTREMELY difficult, if not impossible.
3/ There could be multiple spillover events from an animal reservoir or intermediate host(s) before the virus spread efficiently. These early cases would be extremely difficult to be identify…sequencing is critical.

Latest @WHO Weekly #COVID19 Epidemiological Update published last night (18.01.22)

Case reporting ⬆️ 20% globally in last week, w significant variation around the world.Deaths slightly increased w 45,543 people reported dead. Far far too many when tools can prevent #VaccinEquity
In last 7 days, almost 19 million cases were reported to @WHO. True number of cases is higher & this spike is causing significant burden on health systems around the world bc hospitalisations are also increasing due to #Omicron.

NB variation in % case & death change by region
With thanks to increased #COVID19 surveillance by professionals all over the world and expanded sequencing globally, sequences shared with @gisaid allow for detailed analyses of #Omicron (and all @WHO characterised VOI and VOCs) by @WHO and partners around the world.

🧵Almost 3.8 million new #COVID19 cases & 47,524 deaths were reported last week

The◼️ line is reporting deaths. This should be a much steeper decline bc of available COVID-19 vaccines. But its not bc the world is not prioritising vaccination in people at risk in ALL countries
Important: Delta is dominant worldwide and needs to be controlled. What we do for Delta will benefit Omicron - no matter what we learn about this variant.

Right now, we need to continue to drive down transmission, drive up vaccination coverage in at risk populations.
A plea: Countries that have driven down transmission need to remain vigilant & keep transmission low (& no, I don’t mean with lockdowns). We mean tailored and targeted measures in all countries based on epi and capacities.

A couple of misrepresentations in the @WSJ article that I’d like to address… short thread⬇️
The @WHO SAGO is NOT the next mission team to China. It is an advisory group set up to establish a framework to study the origins of emerging and re-emerging pathogens of pandemic potential when they emerge.
For decades, we have seen the repeated threat of emergence of known & new threats: SARS-CoV, MERS-CoV, avian flu, pandemic flu H1N1pdm09, Ebola, Marburg, Lassa, Nipah, Zika… SARS-CoV-2. #COVID19 was disease X and the next disease X is out there.

Short 🧵 on @WHO’s latest #COVID19 Epi update (available now)

Globally, trends continue to be worrying. Plateauing at more than 4.3 million cases each week and around 67k deaths is tragic - there is no easy way to say this.

In our update, we provide more info at regional levels, a summary of VOC geographic distribution and info on a new global classified VOI “Mu” B.1.621.

Some basics of Mu:
➡️1st identified in Colombia in Jan 2021
➡️Has mutations that warrant further study
(keep reading)
➡️Data on Mu has been shread with @WHO Virus Evolution Working Group 🙏
➡️As of 29 Aug, 4.5k sequences of Mu have been uploaded to @GISAID from 39 countries
➡️ Circulation of Mu is ⬇️ globally & < 0.1% of currently shared sequences of Mu, but this needs careful observation
