If you survive the virus does it grant you immunity against future infections?

My guess would be, "Yes -- in the short term, but [i]only[/i] the short term."

I base this on the fact that the "common cold" is caused by coronaviruses. You might only get [i]this[/i] year's version of the common cold once, then be immune. But by [i]next[/i] year, the viruses have mutated enough that last year's antibodies won't protect you, and you get another cold.

No, the common cold is caused by a Rhinovirus.

Normally yes, but there are reports that some people test positive for COVID-19 after recovery, ie two negative test. I believe that's the exception not the rule. There are also reports from China that a secondary infection is usually more severe.

some recent numbers
 

These are worldwide totals, combining figures from governments of assorted credibility levels.

5065 deaths total /(69623 recovered +5065 deaths)=.0678 case fatality rate = 6.78% of confirmed cases with an outcome determined

Case fatality rate is up slightly from yesterday's 6.46% figure.

Coronavirus - The Hidden Cases - Why We Must Shut Everything Down And Do It Now

[QUOTE]The powers that be in our 'western' societies have decided to do nothing significant against the onslaught the novel coronavirus SARS-Cov-2 is now causing.

There will not even be an attempt to do like China or South Korea which have thrown all resources at stopping the spread of the virus while it was still possible. The 'west' now seem to be beyond that point.[/QUOTE][QUOTE]The Donald Trump administration has done its best to prevent an early detection of the outbreak in Washington State and likely also elsewhere:

As luck would have it, Dr. Chu had a way to monitor the region. For months, as part of a research project into the flu, she and a team of researchers had been collecting nasal swabs from residents experiencing symptoms throughout the Puget Sound region.

To repurpose the tests for monitoring the coronavirus, they would need the support of state and federal officials. But nearly everywhere Dr. Chu turned, officials repeatedly rejected the idea, interviews and emails show, even as weeks crawled by and outbreaks emerged in countries outside of China, where the infection began.

By Feb. 25, Dr. Chu and her colleagues could not bear to wait any longer. They began performing coronavirus tests, without government approval.

What came back confirmed their worst fear. They quickly had a positive test from a local teenager with no recent travel history. The coronavirus had already established itself on American soil without anybody realizing it.

The CDC and the FDA would not have that:

The message from the federal government was blunt. “What they said on that phone call very clearly was cease and desist to Helen Chu,” Dr. Lindquist [the state epidemiologist in Washington] remembered. “Stop testing.”[/QUOTE]Re the attached chart:
[QUOTE][URL="https://medium.com/@tomaspueyo/coronavirus-act-today-or-people-will-die-f4d3d9cd99ca"]Pueyo[/URL]:[INDENT]This is one of the most important charts. It shows in orange histograms the daily official number of cases in the Hubei province: How many people were diagnosed that day.
The grey histograms show the true daily coronavirus cases. Crucially, these weren’t know at the time. We can only figure them out looking backwards.
What this means is that the orange histograms show you what authorities knew, and the grey ones what was really happening.
On January 21st, the number of new diagnosed cases (orange) is exploding: there are around 100 new cases. In reality, there were 1,500 new cases that day, growing exponentially. But the authorities didn’t know that. What they knew was that suddenly there were 100 new cases of this new illness.
Two days later, authorities shut down Wuhan. [B]At that point, the number of diagnosed daily new cases was ~400. Note that number: they made a decision to close the city with just 400 new cases in a day.[/B] In reality, there were 2,500 new cases that day, but they didn’t know that.

Something missing from the chart, is Jan 1 and Jan3, Wuhan police threaten several local doctors with prosecution unless they agree to "stop spreading false rumors" that there's a new virus in town that's dangerous. see [URL]https://en.wikipedia.org/wiki/Li_Wenliang[/URL]

During errands yesterday, I noted that it seemed to be business as usual here in my part of the US midwest, with normal levels of traffic and shopping. The grocery store was nearly empty shelves in places, particularly toilet paper was below 10% ocupancy of shelf space.
