Coronavirus Second Wave?

The new coronavirus outbreak in Beijing grew to 106 cases Tuesday, with 29 communities in the sprawling Chinese capital back on lockdown.

Yet again, a coronavirus outbreak in China is linked to a food market ...

This coronavirus resurgence and reaction is worryingly reminiscent of the unprecedented lockdown of Wuhan and the surrounding regions in central China that began in January.

Beyond Beijing, this new surge is not Asia's only flare-up: Japan's capital city of Tokyo has reported more than 20 new cases havens here day over the past six days.

The surges in two of Asia's biggest capitals serve as a clear warning to America and all other countries: reopening risks reinfection.

Read in its entirety: China races to contain a second wave of coronavirus cases in Beijing

Do you think this will become increasingly problematic?

With the re-opening of the U.S., are we facing a second wave?

Coronavirus has already mutated and there are already patients who have been known to be reinfected a second time. I'm not sure if it was a different or the same strain but the fact they were reinfected shows there is no immunity, hence herd immunity is nonexistent. Add to that the people who have recovered but have severe heart and/or lung disease as a result of the damage covid has done. No, we can't shut down forever, but there are ways to slow progression. Unfortunately, people don't want to follow basic rules and thrive on conflict so they're doing all they can to be obstructionists.

No immunity is a misnomer. We always develop at least a temporary immunity to the particular strain we survive. Memory T & B cells tend to hang around and proliferate rapidly upon second infection wiping it out very rapidly. Otherwise, no one would ever recover. Kill rate would be 100%. Viruses that hijack immune cells like HIV, or viruses that migrate into the nervous system like herpes simplex are another story. They can hide.

Use whatever semantics you want. The point is people have been infected a second time so herd immunity won't work.

Indeed. Resurgence makes much more sense. False negatives with an active low grade infection also could be a contributing factor. These test kits were developed at an absurdly rapid pace.

No. It's real.

South Korea recently reported that a significant number of people with COVID-19Trusted Source have tested positive, then tested negative, only to test positive and experience symptoms, like fever, cough, sore throat, and fatigue, again.

Health officials in South Korea say it’s unlikely these patients got reinfected with COVID-19 a second time since they’re testing positive for a second time so soon, but rather that some people with COVID-19 may be experiencing a viral reactivation.

This is why courses in actual Microbiology, not the watered down health professions version, and basic immunology should be mandatory for all nursing programs.

The reinfections can be because the so called "gold standard" was not achieved. It does not necessarily mean that immunity does not work.

A Dallas woman is detailing her battle with not one but two rounds of coronavirus.

Over the weekend, Meredith McKee posted a tearful photo -- that's now been seen by more than 100,000 people -- from her hospital bed at Texas Health Presbyterian in Dallas.

McKee is sick with the coronavirus again, and she told NBC 5 she wouldn't wish it on her worst enemy.

The U.S. Navy says 13 sailors from the USS Theodore Roosevelt who had apparently recovered from the coronavirus and had received negative test results have now tested positive for a second time.

“We know from ‘normal’ coronavirus studies done in the past you can infect people after about a year following an initial infection,” said Dr Ben Killingley, consultant in acute medicine and infectious diseases at University College London hospital.

From the article, "Health experts in the United States don’t think a reactivation of COVID-19 is likely since we’ve never observed viral reactivation in other coronaviruses."

and then:

"Neuman thinks people are probably “being discharged with some virus still in them, and then the disease returns.”"

The article is from April The last, more recent update I heard on this topic (positive tests after supposedly getting well) was that the positives are a result of RNA remnants, not active Covid, but "dead" Covid, so to speak.

We are learning all the time, and I certainly do not have all or even a small minority of the answers!

Explain.

To summarize, if a person is not exposed to enough of the antigen and therefore does not produce an adequate immune response, they will not have enough antibodies to give long term immunity.

The gold standard is one of the reasons that a vaccine takes so long to produce. First, they need to find where that threshold is to achieve full immunity.

You will notice that some vaccinations require more than one dose in order to be effective. Much more research is needed, and it's far too early to jump to any conclusions.
