1 Those who reject #ZeroCovid say absolute 0 is impossible. IMO 0 covid advocates just want measures to reduce transmission (R0<1=case # decreasing). I'l start adding advocates of 0 covid to this thread to prove it has wide support among scientists, PH/ID experts, researchers...
Adding this for record 😱😡😡. The #ZeroCOVID advocates should feel honoured for being in the same sentence with anti-vaxxers Dr Covid is Definitely not an Airborne Pathogen’s view. How dangerous are experts who want to save lives?!
#ZeroCovid & similar hashtags seem to hv disappeared fr @Twitter ? I think #ZeroCovid is also a “broad church” -reality is 0 is never absolutely 0 in current situation,but the key is we work to reduce transmission toward 0 instead of solely relying on vax
I encourage everyone to cal R_effective (Re) using this formula:
Re=R0 x (1- vax rate * Ve),
even if Delta’s R0 is only 5 (CDC says 5-9), if Ve=80% (Pfizer is prbly <80% against Delta), we need 100% vax rate to break even Re=1. In reality, R0 5-9, vax rate 50-90%, Ve 40-88%.
The above tweet is fr a privileged position of countries w sufficient vax supply. For vast majority of low income countries w/o much vax supply ppl hav to reply mainly on NPIs to reduce Re to below 1 to prevent mass deaths. Best thread on vax/Re/booster:
China has defeated the most widespread (in over 2 dozen cities) Delta outbreaks in the country so far. Mass testing, TTI, precision lockdown r the key tools it has used. Some of China’s measures may not b necessary, but all that worked can be copied elsewhere. Are there any...
...reason why Sydney can't do city-wide pooled mass testing? Sydney's population is about half of Nanjing's. Import millions of PCR testing kits & get thousands of nurses, medical students, student nurses etc do the swabs? Fly the samples to all over AU to process. Or get ...
...everyone in NSW do rapid antigen test? Just import millions of the test kits and get Auspost deliver them to every letterbox and go. There r many things that could be tried and could work but leaders need to think out of the box. @GladysB@BradHazzard@NSWCHO@MarkMcGowanMP
