Millions have died from #COVID19 since the start of this pandemic and 15000 are still dying each week.

15000 mothers, daughters, fathers, sons, brothers, sisters, friends… people we love.

I know we are tired, but when did this become acceptable?

A short thread…
Globally, over the last 4 weeks, 26,722,228 new cases and 62,892 new deaths were reported to @WHO. That’s a 15% ⬆️ in new cases & a +35% ⬆️ in new deaths over the reporting period.
We expect cases to continue to occur given the limited use of public health and social measures🌎, but #COVID19 hospitalisations, deaths & #LongCovid can be minimised.

Efforts need to be made to strengthen the use of life saving interventions. We can do this AND live our lives.
Omicron #BA5 is the dominant circulating variant of concern right now. However, reduced surveillance, testing & sequencing globally is making our ability to track known & detect new variants much more difficult.

Details of #Omicron subvariants ⬇️
There will be more variants with such intense circulation. This virus does not yet have a seasonality or act predictably.

Future variants will be more transmissible, may have further immune escape but we do not know if they will be more or less severe.

Lives can be saved now with early testing, the right clinical care & treatments and vaccination administered by trained, protected & respected work force. Vaccination amongst those most at risk in all countries is not as high as it should be. #VaccinEquity is not just a hashtag.
Infections and risk of #LongCovid can be reduced with simple measures.

COVID-19 vaccines are working incredibly well at preventing severe disease. Get vaccinated and get all recommended doses when it’s your turn.

Governments need to focus on reaching at missed risk people.
I may be away with my family at the moment, but #COVID19 is never out of my mind.

There is no zero risk but we can live our lives while taking simple measures: get vaccinated with all recommended doses; wear a mask while indoors, spend time outdoors,ventilate, test, seek care.
My family and many others globally are fortunate to have access to life saving tools. Not all families do. We must continue to fight for #VaccinEquity and access to affordable and reliable tests and treatments.

There is more work to do.

🧵1/Five years ago today, @WHO became aware of the first cases of pneumonia of unknown etiology in Wuhan, China. A massive global storm was already brewing—a storm that would shut down the world with profound impacts that reverberate to this day. #COVID19
2/ This moment changed all our lives. #COVID19 has taken so much from us, but it has also taught us invaluable lessons. Its legacy must not only be defined by pain and loss, but by the collective progress we make toward stronger pandemic preparedness.
3/ I want to first take a moment to thank @DrTedros @DrMikeRyan for their incredible leadership, to all my colleagues at @WHO, to all governments, public health professionals, and partners for their tireless work on #COVID19. #ProudToBeWHO

As we head into the winter season in the northern hemisphere, I am worried about current #COVID19 vaccination levels.

A short thread 🧵about where we are and what we need to be doing…
Vaccination remains a critical tool for preventing the serious impacts of #COVID19, especially in those at high risk of severe disease - including older adults, individuals with chronic or immunocompromising conditions, pregnant women, and health and care workers. Image
A number of recent studies continue to demonstrate the impact #COVID19 vaccines have had in preventing death and disability from both acute COVID-19 and increasingly from Post COVID-19 Condition (PCC or #LongCOVID) & more research is needed. However...

Despite not being in the news, #COVID19 has not gone away. @WHO continues to work with all countries on surveillance, reporting & risk assessments of circulating variants (JN.1, KP.2, KP.3…) & their impact.

Our latest Epi Update (with variant update) ⬇️

Yes, the impact of COVID is far less than it was in a few years ago, but we can’t become complacent: Recent vaccination coverage in at risk groups is poor, there are ⬆️ trends in hospitalisations in a number of countries, the virus continues to evolve…

technet-21.org/en/resources/r…
… COVID does not circulate with predictable seasonality, our understanding of acute and long term effects (#LongCOVID) is still weak, there is little effort to prevent the spread. Prevention of infection remains impt even with the overall impact of #COVID19 lower than 20-22, etc

Short 🧵 re #H5N1

An integral component of @WHO’s overall global strategy for #influenza pandemic preparedness activities is the development of candidate vaccine viruses (CVVs) representing influenza viruses of zoonotic and pandemic risk.
Selection and development of #influenza candidate vaccine viruses (CVVs) are the first steps towards timely vaccine production, when needed…
Due to the evolving nature of influenza viruses, the genetic and antigenic characteristics of contemporary zoonotic influenza A viruses and development of CVVs for pandemic preparedness are summarized and published twice a year ().who.int/teams/global-i…

🧵Lots of interest in #H5N1 in 🇺🇸 so wanted to provide a little background on @WHO’s work in #flu (For latest in US see: @CDCgov @USDA @US_FDA)

And some info on the H5N1 flu vaccine pipeline in humans (note, we don’t need this yet, but I’m getting a lot of questions about this)
@WHO’s work in #flu spans >7 decades with the Global Influenza Surveillance and Response System (GISRS) who.int/initiatives/gl…
GISRS is currently composed of:
152 WHO National Influenza Centers in 130 Member States
7 WHO Collaborating Centers for Influenza and 
12 WHO H5 Reference Laboratories

For the last few years, @WHO and @CERN have been developing a risk assessment tool to estimate indoor airborne transmission of #SARSCoV2 to better advise on risk mitigation measures for #COVID19.🧵

home.cern/news/news/know…
Note: The risk assessment tool itself has been online for more than a year, helping our member states and partners reduce the risks of airborne transmission indoors. 

partnersplatform.who.int/aria
The model behind the tool and updated data from literature reviews were published this week.

We are grateful for the collaboration with @CERN and our ARIA Technical Advisory Group on this incredible work.
