They do not know for sure if you cannot catch it a second time.
There have been some instances where recovered patients get sick a second time.
People who recover, test negative, then test positive and have symptoms again probably never completely cleared the virus in the first place. It is a relapse, not a reinfection.

Not "it is a relapse" though. "It's probably a relapse" is more appropriate.
They have also blamed false negatives for testing.
At this stage of evolving everything is a "probable" or "possible" until science gets a chance to validate/invalidate it.
"We don't know very much," says Matt Frieman, a coronavirus researcher at the University of Maryland School of Medicine in Baltimore. "I think there's a very likely scenario where the virus comes through this year, and everyone gets some level of immunity to it, and if it comes back again we will be protected from it — either completely or, if you do get reinfected later, a year from now, then you have much less disease."
"That is the hope," he adds. "But there is no way to know that."
Look at the amazing, concerted response in South Korea that is saving lives. They were on a similar trajectory to Italy at the start, but sprung into action and are seeing far better results.
Did we not spend billions and billions and billions on emergency preparedness since 9/11?
The biggest takeaway from that crisis is that there was a general lack of cohesion and communication between levels of government. It's been 20 years and you`d think we could say "we got his", but we don't. This is no way a criticism of the front line responders. They seem to have as many questions as the rest of us. It's a systemic problem.
Because we are in the midst of a crisis, I don't want to say too much. The time for evaluation and criticism of what has occurred will come and I believe will come in a timely manner. Right now, priority has to involve keeping others from becoming infected and treating those who are infected.
However, several questions stand out to me:
1. Did intelligence agencies warn of the corona virus earlier?
2. Why was the White House Office on Pandemics abolished?
3. If we couldn't see corona virus coming, we should have been able to see that some kind of pandemic was coming. Why wasn't more done to prepare for a pandemic? Examples: Stockpiling personal protective equipment; having a national policy in place for school and business closures; and having the equipment of a "czar" to handle pandemic disease.
4. Why are we always playing "catch up" in this country?
Coronoviruses are heavier than other viruses--one reason they drop to the ground after 6 or so feet of being in the air. A good thing, less contagious, as long as you're not right next to someone who coughs or sneezes w/ the virus.
Good article. https://www.nytimes.com/2020/03/20/o...rus-facts.html

I think I will believe WHO over a NYT opinion piece.
There's probably no real dispute now that its "airborne" or at least spreads for longer distances then initially realized, staying in the air longer. So much of the early advice was based on what was anticipated from influenzas or even other coronaviruses. The light cough characteristic of covid-19 is hypothesized to create finer or lighter particles that are less likely to fall quickly to the ground.
One of the problems we're running into is that 'expert' opinion is getting revised but the earlier pronouncements are still being picked up by the news and repeated as fact even by public officials. Even current CDC advice appears out of date.

There are too many precautions that people aren't following or not careful enough. People should refrain from useless chatter, when you're indoors such as the markets. Don't have any conversation with the cashier or store workers. I also don't know why so few store workers wear the masks. They are potentially the biggest spreaders of the disease. Places like Korea can contain because majority of people wear masks. Masks prevent airborne droplets. If you don't see workers wearing face masks then don't talk to them. I see a lady having a small chat with the cashier, that's how you can get sick.

yeah..I've stopped going to the CDC. WHO is even a bit behind but not much.
The research articles coming out seem to be the best source of this evolving crisis.

There are no masks to be had or bought. That's why.
Hospitals have taken to ask the people to sew surgical masks and donate them. They will use them, sanitize them and reuse them. They have to go old school on masks because of shortages.
Different times call for different measures. When Covid-19 hit China, I was concerned, as were many public health professionals, about what could happen and urged rapid action to understand more and prepare. But few of us anticipated the catastrophic impact the new virus has had in Wuhan, in Italy and may soon have in many other places.
For most people, there is simply no frame of reference for this pandemic. Never in our lifetime has there been an infectious disease threat as devastating to society. Never in our lifetime have we seen a rich country like Italy face the need to ration respirators. And never have we seen the fear that millions of health care workers around the world feel about being infected by the virus -- justified fear we must address.
Possible treatment option in the Journal of Clinical Investigation
Actually, an old treatment that was, I believe, used in the past

Former CDC director: There's a long war ahead and our Covid-19 response must adapt
