2019 - nCoV (novel coronavirus originating in Wuhan, China)

Or, since COVID is another strain of coronavirus like SARS, it could well be this strain will just *disappear* like its predecessor.

Or, since COVID is another strain of coronavirus like SARS,

SARS-COV-2 is different coronavirus than SARS. SARS-COV-2 has at least 8 strains running around the world I read a few weeks ago. If we build an immunity to one strain, will we have an immunity to other strains? IF SARS-COV-2 mutates a lot like the flu does, then a vaccine will be needed for every major mutation. It's why we need to get this virus out of our bodies before it infects too many people increasing the chances of major mutation and becoming harder to control. Trying for herd immunity may actually help the virus more than us. Experts can't agree which is the best way to attack the virus. Exposing ourselves to achieve herd immunity or hide from the virus. Here is a 2017 article explaining why we don't ever develop immunity to the common cold coronaviruses.

WHO already said this virus isn't SARS so there is no relation except in name. This new virus behaves much differently. SARS didn't disappear on its own. It was beaten back by vigorous action before spreading around the world like SARS-COV-2 is doing. SARS was easily beat because it was quick and easy to identify those who were ill and remove them from the population.

There never was any vaccine for SARS. Dr. Fauci, when asked about it, simply said there never was any vaccine because SARS just *disappeared*.

I watched Dr. Fauci say that. He didn't lie but he also didn't tell the whole story. There has never been a vaccine created for any coronavirus in history. Not for SARS, not for MERS, and not even for the harmless coronaviruses that cause the common cold. SARS disappeared only because of human intervention. China probably thought the same level of human intervention would get rid of the pathogen of the century. They were wrong. Dr. Fauci can't tell the whole truth because the truth hurts and may cause panic. There are experts that say Dr. Fauci's prediction we may have a vaccine in 18 months was overly optimistic. I listen to Dr. Fauci but I also know he wants to create hope to prevent depression and he is careful not to create panic.

BillyB, do some research before posting here. Don't go by your 'stories' you read on the  internet. Please refrain from your 'IF' situations
Yes, there are at least 8 strains of SARS CoV 2 but they mutate slowly( maybe twice a month), much different than flu which mutates ~~twice as fast. Because of slow mutation SARS CoV 2 strains are fundamentally similar so they do not  enhance viral virulence.

There are 8 strains of SARS COV-2 out in a matter of months and that is fast. New strains are not considered a major mutation. It's possible our immunity system and one vaccine can handle all 8 strains but if SAR COV-2 goes under a major mutation, a new vaccine will be needed to for the mutated virus and our immunity system will definitely be inneffective.

Don't go by your 'stories' you read on the  internet.

I'll just "wing it" next time like you do. Lol

WILL THE SUMMER SEASON REDUCE NUMBER OF INFECTIONS?


An epidemiologist associated with Harvard has analyzed whether the pace of COVID-19 infections could be seasonal.

http://ccdd.hsph.harvard.edu/will-covid-19-go-away-on-its-own-in-warmer-weather/

He named three factors affected by the season:

1.  The environment  - Some viruses survive best in dry, cold air.  Droplets from coughing and sneezing travel farther. 

2.  Human behavior - People socialize differently in summer than winter.

3.  Human immunity  - The human immune system is weaker in cold months).and the dynamics of disease more generally (an epidemic that begins in one season tends to end in another).

4.  History - viruses with a long history such as flu do exhibit seasonality, yet new viruses tend not to because the whole population is susceptible at the start


He concluded that that COVID-19  "...may transmit somewhat more efficiently in winter than summer...The size of the change is expected to be modest, and not enough to stop transmission on its own."

I look in Florida and notice that the warmest region (Miami)  has a much higher proportion of reported infections.

Maybe time to look into an Igloo in northern Alaska ??

May be related to sunlight killing the virus left on outside surfaces.

I favor the notion that sneezed or coughed antigens are more rapidly evaporating in the warm air making it more difficult for the disease to transfer.

A friend picked up my golf club, formerly a friendly gesture but now a "no-no."  So I put the club in timeout, basking in the sunlight, letting UV rays destroy the virus as well as my exposed skin.

Evaporation results from the movement of unsaturated air.  Its plenty warm in Florida, yet in Florida the relative humidity approaches 100%, so sweat stays on the skin (as do droplets).  You live in California where sweat evaporates, which is cooling.

Why did you throw your golf club down ?

I don't throw.  I admit sometimes struggling to control the impulse. 

Humbling sport, and I can not blame my mistakes on others.

AND NOW BLOOD CLOTTING DEATHS

As if this disease was not bad enough with the severe respiratory complications, reports are being published that blood clotting problems to the degree of “hemostatic derangement" are killing a significant number of  COVID-19 patients.

Back in January when I was trying to learn about this new coronavirus and before it was named SARS-COV2, I looked up a couple other coronaviruses to get an idea on what to expect and found this article on SARS.

As Zhang interviewed and took pictures of more than 50 SARS survivors, mostly from Beijing, a horrific tale of their "lucky" escape began to emerge.

"They were decaying physically and falling apart mentally," she says.

Zhang discovered that more than 360 people were living with the devastating after-effects of SARS. The steroids used in their treatment had left them with permanent damage to their bones and lungs.

"They couldn't walk or breathe properly," Zhang says.

They were unable to take care of themselves, and some were forced to go in for joint replacements.

The more we allow people to get infected, the more people we will have that needs expensive short term or long term care. Even if we find a cure, our economy will take a hit long after.

According to today's press briefing...experts agree that this virus actually survive better in warm, dry air climate like So. California, than the warm, high humidity air like Florida's.

Boy, these daily briefings are getting pretty dangerous with all the unproven anecdotal information that is being basted out in desperation.

Maybe I'll start huffing window cleaner and see if that works.

Indeed, the disinfectant remedy is bizarre.  I missed that hearing that part, yet from what others have said, it was regrettable.  Give Trump credit -  he stopped short of a personal demonstration.   

The humidity and UV factors were discussed here.  Does it matter that our number of viewers may be less than CNN-Fox-et al?

Here's a new one.  Viagra, not as a preventative, but after the respiratory system is stressed.

Gator,

If I 'go', it's gonna be with a stiffie so yeah if that's what it takes I'm all for it.

This entire presidency has been bizarre and getting more so by the day... but I'll add a disclaimer:  Please don't follow my suggestion above and huff Windex or any other household cleaner for that matter... It'll kill you.

I read that too, and it was observed for  air droplets as well as virus resting on surfaces. 

   On nonporous surfaces such as stainless steel, the new coronavirus takes 18 hours to lose half its strength in a dark, low-humidity environment, Bryan said.

In a high-humidity environment, that half-life dropped to six hours, and when the virus was exposed to high humidity and sunlight, the half-life dropped to two minutes, he said.

Researchers found a similar effect with the coronavirus that was suspended in the air - simulating the coughing or sneezing that often spreads the disease. In a dark room, the virus maintained half its strength for an hour.

But when exposed to sunlight, it lost half its strength in 90 seconds, Bryan said.

I understand the destruction by UV rays min sunlight.

How is humidity a factor?   I can only guess as to the explanation.  Some biological, chemical, and/or physical action is breaking down the lipid shell of the virus, and it is more active in humid air.  For example, bacterial decomposition is higher in humid than dry conditions, explaining why the mummies in Egypt have survived 3,000 years. 

This summer in Florida while under attack by mold and mildew fungi, and facing heat exhaustion on the golf course, I can thank my lucky stars.

Trump is running out of things to give people hope. Now got to be creative.

The humidity and UV factors were discussed here. 

More hope. Singapore, a city-state of 5.6 million is currently experiencing an outbreak with 1000 people getting infected each day. They are experiencing 88 degree Fahrenheit or 33 degree Celsius with 88% humidity weather lately. Last month WHO said it's false hope the virus will go away during warmer months. Summer may help slow the virus down but it still spreading fast enough to create outbreaks as Singapore is learning.
