UPDATED @WHO guidance: Critical preparedness, readiness and response actions for #COVID19

Continue to take all necessary public health & social measures to reduce exposure to #SARSCoV2

Variants of #SARSCoV2 are circulating, some with increased transmissibility. However, the preparedness, readiness and response actions that are needed remain the same, and should be reinforced.
Countries need access to vaccines and should administer #COVID19 vaccines according to their National Deployment and Vaccination Plans. #COVAX @WHO
Countries should be able to deliver the #COVID19 care pathway for patients, including life-saving therapies of corticosteroids and oxygen for those with severe disease, regardless of transmission scenario. @WHO
There are seven transmission scenarios for #COVID19: no cases, sporadic cases, clusters of cases and four levels of community transmission. Countries should assess the transmission scenarios at sub-national levels using data captured from surveillance and health systems. @WHO
Countries should respond to all #COVID19 transmission scenarios while including communities in decision making processes to enhance adherence to public health and social measures. @WHO
Prioritization of resources for each technical area will depend on which #COVID19 transmission scenario(s) a country is facing, as well as the response capacity. (Countries could be facing multiple transmission scenarios at the same time). @WHO
There is still much to understand about #COVID19 and its impact in different contexts. Preparedness, readiness and response actions will continue to be driven by rapidly accumulating scientific and public health knowledge.

Preparedness, readiness is a constant. @WHO
Last few pages of this guidance provided links to the many guidance materials by @WHO. No one guidance document contains all recommendations.

@WHO is grateful to work with so many collaborative, dedicated, smart, humble public health professionals across so many disciplines 🌎

Short variant thread ⬇️

We expect that more variants will continue to be detected as the virus circulates and evolves and as sequencing capacities are enhanced worldwide.

It’s even more critical we drive down and keep down transmission. @WHO #COVID19
As we have said, each variant identified needs to be properly assessed, which is why WHO established the Virus Evolution Working Group in June 2020, and why there is a Global Monitoring and Assessment Framework for #SARSCoV2 variants, coordinated by @WHO.
Re the report of variant from Vietnam: @WHO 🇻🇳 country office & @WHOWPRO are working w MOH 🇻🇳. The variant detected is B.1.617.2 with an additional mutation(s), but more info soon.

Remember: variants are constellations of mutations. Many VOI/VOC have similar mutations

If you live in an area where #COVID19 is spreading:

➡️🚫mix w people outside of your household
➡️🚫crowds & gatherings
➡️stay🏠if you can (& open🪟) as many cannot bc of essential work
➡️reconsider travel
➡️💉when you can
➡️seek help when needed

play your part


➡️isolate if a case (& call hotline or medical provider)
➡️quarantine if a contact
➡️help others where you can, but meet outdoors instead of indoors
➡️follow local guidance

Do what you can to help yourself, family and community

Do it for you, do it for them
Be kind
Be safe
Be informed
Be prepared
Be supportive
Be alert
Be ready

Have a plan, reach out for help and give yourself a break

We are in this together, and we will get through this together

1/7 Short🧵 (@WHO has issued a new ventilation roadmap for #COVID19 ... keep reading!)

Transmission of #SARSCoV2 is a function of how, when and where transmission is occurring and the interventions that are in place.

@DrTedros @DrMariaNeira @DrMikeRyan
2/ When assessing potential #COVID19 exposure risk consider: location, proximity, and time

3/ Let's take a closer look at location: studies show that the risk of #SARSCoV2 transmission is higher indoors compared to outdoors, and particularly risky in indoor settings with poor ventilation, especially where people spend long periods of time. #COVID19

Household Transmission of #SARSCoV2: A Systematic Review and Meta-analysis

Interesting paper - a few highlights (taken directly from paper) - worth a read 👇

Meta-analysis of 54 studies with 77 ,758 participants, the estimated mean secondary attack rate (SAR) for household contacts was 16.4% (95% CI, 13.4%-19.6%) & family contacts was 17.4% (95% CI, 12.7%-22.5%)
Household and family SARs were >3 times higher than for close contacts (4.8%; 95% CI, 3.4%-6.5%; P < .001)

🤔 Want to know how @WHO guidance is developed?

Here’s a brief explainer and🧵⬇️:

@WHO is an evidence-based organization.

The prevention, detection & control strategies & technical guidance that we develop are based on robust science, generated through extensive, collaborative research, & evaluated by a broad network of experts

@WHO works with scientists, clinical and public health professionals, people affected by public health challenges, across the world

1/ Re-sharing this thorough systematic review & meta-analysis of % asymptomatic infection & asymptomatic /presymptomatic/ symptomatic transmission of #SARSCOV2 - @nicolamlow & co

2/ (Preprint of this has been available for some time, & peer-review paper available in Sept) but re-sharing to make a few points still critical today.

We have a long way to go, but we can #ControlCOVID

hear me out 👇
3/ Review addressed 3 questions:

1️⃣what proportion of cases never experience symptoms at all during their infection?

Findings: Estimate 20% (95%CI 17–25)
