Looking at figure 4 in the paper gives me some comfort since the majority of the population centers in the northern hemisphere could approach a R of 1 in July.

#32The ME in MERS stands for Middle East, since outbreaks of it are always from camels. Such places are some of the hottest on the planet. MERS is another form of coronavirus. It is foolhardy to think spring and summer weather will save us.
It's a related but different virus. Also, the environment in the Middle East tends to be arid.
Re: High Temperature and High Humidity Reduce the Transmission of Covid-19
#33To be pedantic, COVID-19 is the disease, SARS-CoV-2 is the virus. It's like HIV vs AIDS.
If you reduce the transmission of the virus, do you not reduce the transmission of the disease?
I mean, that's why it's pedantic.
Technically you can't "transmit" the disease. The disease consists of the effects on the body.
Also, you can transmit the virus without having the disease, which is what makes it dangerous since you have no idea. It's like you can transmit HIV without having AIDS for years:
>Acquired immunodeficiency syndrome (AIDS) is defined in terms of either a CD4+ T cell count below 200 cells per µL or the occurrence of specific diseases in association with an HIV infection
That doesn't happen for a long time (or today, for a lot of people, never).

#34Here's a likely related paper from 2007: https://jvi.asm.org/content/82/4/1899 In this study, a human immunodeficiency virus (HIV)-based pseudovirus system was employed to address these issues. Our results indicated that the SL-CoV S protein is unable to use ACE2 proteins of different species for cell entry and that SARS-CoV S protein also failed to bind the ACE2 molecule of the horseshoe bat, Rhinolophus pearsonii.…
Posts like this tend to get flagged quickly on HN. Meanwhile, you can freely conspiracy theorize all you like about the machinations of the CIA, NSA, etc., regardless of how little evidence you have. It's the same on other social media websites. Zero Hedge got deplatformed from Twitter for talking about this. The CCP is exerting a frightening chilling effect on public discourse, even in America.
It seems like you want me to jump to a conclusion, but all I see is a researcher that studied a virus that has potential to jump to human hosts, and that has a natural reservoir in the area that the do their research.

It is extremely frightening, and it's important that we continue to fight for freedom of expression on all platforms. Unfortunately so many have an innate bias against the US that any criticism of it is considered fair game regardless of how conspiratorial or absurd.

#36This study fits a two-variable linear model to a high-dimensional nonlinear process.

Can someone with a better understanding of molecular biology and virology explain what this means? I don't want to jump to conclusions.
The paper describes how virologists in Wuhan engineered a "SARS-like" virus -- previously limited only to bats -- specifically to make it infective in humans via the ACE2 receptor. That's the same receptor used by the SARS-CoV-2 bug we're fighting now.
Note that the paper was submitted 12 years ago. They've had a lot of time to work out the kinks, if they were so inclined.
EDIT:
I want to repeat what I've said in other comments, because what I initially said was inaccurate. These researchers didn't actually create a new coronavirus, but rather a much simpler and safer virus purpose-built to test some receptor-binding structures.
This is a well-established way to study viruses safely, and this kind of work is critical if we're to learn how to develop vaccines faster in response to epidemics.

No, they didn't just study it. They engineered a variant of a SARS-like coronavirus specifically to be able to infect humans. The paper's abstract says they did this by "combining a human immunodeficiency virus-based pseudovirus system with cell lines expressing the ACE2 molecules of human, civet, or horseshoe bat."

#39Excuse my ignorance but would a colder temperature but with rain help prevent due to the high humidity or does it require heat AND humidity?

SARS infected 8000 humans in 2002. It was a coronavirus. (That's why the current one gets the "-2" suffix.) Nature beat the researchers by a number of years (and they were presumably trying to figure out how).
