Contact tracing, testing and isolation is important against many infectious disease outbreaks, such as Ebola and post-vaccine measles. It is ineffective, naïve and counter-productive against COVID19, influenza, pre-vaccine measles, etc, and by definition, against any pandemic.

So... no testing, no isolation, no contact tracing. Just preventive measures in vulnerable population would be enough until vaccination succeeds?
Hi Iciar, Self-isolation and protection of the elderly and other high-risk people is very important until there is herd immunity through a vaccine or natural infections.https://www.spectator.co.uk/article/herd-immunity-is-still-key-in-the-fight-against-covid-19 …

There will probably never be a natural herd immunity from Covid 19 and given the nature of coronaviruses as a whole, probably never a vaccine with more than 40-50% efficacy. So what then? And now?
-
As with prior pandemics, all countries will eventually reach herd immunity whatever strategy they use, either through vaccines, natural infection or a combination of the two.https://reaction.life/we-may-already-have-herd-immunity-an-interview-with-professor-sunetra-gupta/ …

Interesting approach and brave statements. Nobody understands anymore what 15.000 positive individuals per day in my country means. The goal then should be to minimize the death toll in the vulnerable pop, if achieved the pressure in the intensive care units would be acceptable

Can we call it population immunity not herd immunity please? Unlike cattle, people assess risk and adjust behaviour, and are exposed differently (20% have 80% of contacts?). Herd talk, as if culling weakest members, discredits policy in public mind

Thank you but just how long will herd immunity take to develop? It's a tantalising view that this will occur but what is the potential increase in death rate to achieve this level of immunity?

Parece k no has entendido lo k has leído.... Estamos hablando de prospectivo y a partir de ahora k ya se sabe k hay transmisión aérea. Tienes alguna idea o sigues utilizando víctimas para trolear? Es muuuy fácil y muy cuestionable tu respuesta. Propón solución factible pej

Define elderly. Define high risk groups. Who interacts with these groups? Can you obtain herd immunity with clusters of susceptibles?

Any examples of herd immunity countries successfully protecting at-risk people? The only success I have seen is in countries with aggressive suppression strategies. Possibly due to underfunded aged care (for example) which would take years to remediate
