hi vesicles

Is it possible that cv19 will fade out just like SARS? I read that it is getting weaker and many infected over 80 is able to survive.

Just wondering why Covid is not fading away in the higher summer temperatures as expected and it must be getting pretty warm in Texas?

It was hoped rather than expected that it would. Viruses are immune to hope unfortunately. There was no evidence that the virus would be stymied by summer weather alone and countries like Ecuador acted as a grim case study that the virus was more durable than many had hoped. Yes, high enough temperatures could destroy the virus, other posters have mentioned metal surfaces exceeding 50C in hot weather, but that is only a small part of the environment. In any case, with the ubiquitous nature of air-conditioning in hot regions, the virus will have no shortage of indoor concentrations of people sheltering from the heat. The more developed, the more vulnerable imho.

Well, even SARS didn’t end until July in 2003 in Guangzhou, which is also very south and very hot and humid. So even if, that’s a huge IF, the COVID-19 fades away, we will most likely have to wait a few more months.

These viruses are all unpredictable. No matter what they look like at the beginning, as soon as they start mutating, evolution takes over. And no one can predict how it will mutate since the survival of every kind of mutants depends on so many variables. No one or any existing mathematical model can predict such complex changes.

We can have two identical virus particles starting out on the same human. Any random event might allow a more lethal mutant to survive, while some other events might give the advantage to a more virulent mutant.

Vaccine news: one of China's leading scientists thinks that the vaccine from the Wuhan Institute of Biological Products will cover the new genotype from Beijing:
In response to recent new cases in Beijing and the discovery of a new genotype of the virus through whole-genome sequencing, some experts worry that for the new genotype, "the vaccine may weaken or even not work".

However, Yang Xiaoming, chief scientist of the national "863 Program" vaccine project and chairman of CNBG, told Science and Technology Daily he had noticed the new genotype, but it is "still within the coverage of the vaccine whose Phase I/II unblinding occurred today", so it will not affect the effectiveness of the current inactivated vaccine.

One of China's leading vaccine expert thinks that this vaccine will cover the newly discovered Beijing strain of COVID-19 virus.

Chinese COVID-19 vaccine candidate the first to start phase 3 clinical trials worldwide
Chinese-developed COVID-19 vaccine candidate is the world's first to enter phase three human clinical trial which will begin in the United Arab Emirates (UAE) on Tuesday. It is also the first overseas clinical trial for a Chinese-grown vaccine, and is seen as an important step toward putting the vaccine into use and benefiting all humanity.

The opening ceremony of phase three clinical trials for the inactivated vaccine, which may consist of whole, inactivated agents developed by China National Pharmaceutical Group Sinopharm (Sinopharm) was held online in China's Beijing and Wuhan, and the UAE's Abu Dhabi on Tuesday.
...

The Wuhan Institute of Biological Products, affiliated with Sinopharm, announced on June 16 that the company's COVID-19 inactivated vaccine candidate had not shown any severe adverse effects in the first two phases of clinical trials, and it is the first vaccine candidate in the world to show favorable immunogenicity and safety.
