I’ve read in many articles that immunity lasts from months to years, similar to something like influenza.

There has not been a definitive statement regarding this—but authorities seem sure that there is at least SOME immunity, and perhaps considerable immunity in the presence of T-Cells.

I read often about a “double-edged sword”—in that there is extensive antibody activity, which could lead either to recovery or to the development of more severe symptoms caused by a “hyperactive” immune response.

Be that as it may, I am optimistic that I have similar immunity to that which occurs when I’ve had influenza.

I’ve never read about a potential second infection being “worse.” And I’ve done extensive research.

I’ve only had COVID once.

EFFECT OF COVID-19 ON SPECIALIZED MEDICAL DOCTORS

There was an interesting study on the effect of the coronavirus on different medical specialist.

But before I discuss the results of the study, I should begin by discussing the definition of "Resident". In the U.S. a medical doctor generally goes through 4 years of undergraduate training, if selected then goes through around 4 years of med school. After that they go through several years of hands-on training generally in a hospital setting before they are considered full fledge medical doctors.

As Wikipedia puts it:
Residency or postgraduate training is a stage of graduate medical education. It refers to a qualified physician, podiatrist, dentist, optometrist, veterinarian, pharmacist or (one who holds the degree of MD, DPM, DDS, DMD, DVM, DO, OD, PharmD, BDS, or BDent; or MB; BS, MBChB, or BMed) who practices medicine, usually in a hospital or clinic, under the direct or indirect supervision of a senior clinician registered in that specialty such as an attending physician or consultant. In many jurisdictions, successful completion of such training is a requirement in order to obtain an unrestricted license to practice medicine, and in particular a license to practice a chosen specialty. An individual engaged in such training may be referred to as a resident, house officer, registrar or trainee depending on the jurisdiction.
----------------------------

Our group recently studied the impact of the COVID-19 pandemic on New York Area residency programs during the time period in which New York City became the epicenter of the pandemic. We surveyed approximately 340 residency programs in the area during a 10-day period at the beginning of April 2020; in hindsight, this time represented the first peak of the pandemic in New York City.

We received responses from 91 residency program directors who were collectively responsible for the training of 2,306 resident physicians across 24 specialties. We sought to identify the number of residents infected with COVID-19, and we queried if certain specialties might be at higher risk for infection. We asked about the availability of personal protective equipment (PPE). In addition, we studied numbers of residents quarantined, as well as the numbers of residents redeployed to other services to help in the COVID-19 fight.

We studied the results from seven specialties with >100 residents represented in our survey and found that three specialties, anesthesiology, emergency medicine, and ophthalmology, segregated as higher risk. To many, the risks of anesthesiology and emergency medicine are self-evident – physicians in both specialties interact with aerosols during intubations, and emergency physicians also interact with a number of sick patients whose COVID-19 status is unknown. That ophthalmology was also a higher-risk specialty may be surprising to some, but not when one considers that ophthalmologists see a very high volume of patients at close proximity (<1 foot ) to patients’ mouths.

Our study is notable because it is one of the first to show the direct impact of the COVID-19 pandemic on healthcare workers, and it is also the first to study risks of infection by specialty. Other specialties, such as otolaryngology and dentistry, have been suspected of being at higher risk for similar reasons as discussed above, but our study did not have enough responses from these specialties to characterize their specific risk levels.

From what I am reading, individuals with COVID-19 will sometimes relapse. A relapse is different than a reinfection. In a relapse, the virus has never really gone completely away. These are people who are having a hard time getting over it. The virus damages many other organs than just affecting their lungs. And this initial damage begins to appear over time.

According to one news article: Scientists have discovered that the virus attacks much more than the respiratory system, identifying circulatory, digestive and neurological problems tied to the virus. An uptick in strokes and heart attacks among otherwise healthy individuals has also been attributed to Covid-19. Ryan said it also appears to be hitting the liver and kidney functions as well as other vital parts of the body. He added that even after people are released from the hospital, “many are experiencing longer-term issues with energy.”

This should be balance with: most younger individuals only suffer minor effects from the virus and quickly recover.

I am fully recovered from COVID with no lingering effects. I’m walking 20 miles a week at 3.5 to about 4.2 miles per hour. I will be 60 in just over 7 months.

I feel good that I have a sort of “closure.”

And know that I have a certain amount of immunity, though how much is unknown.

I may have read something about the "Spanish Flu", or some other disease, and confused it with the CV.
I did a quick Google but couldn't find the article again.
Meh,
Time to move on. :wink:

Based on what I have experienced, and now with the knowledge of CV symptoms, I heavily suspect I had the CV last year before it came to mainstream media attention.
I've been meaning to get an antibody test, but procrastination is my buddy, atm. <sigh>

You might have confused the possibility of a "second wave of infections" with "reinfections of individuals". This virus is a seasonal virus and it may return in the fall.

In the viral pandemic of 1918-1919, the infection first struck young healthy soldiers preparing to enter the battlefield in Europe to fight the First World War. It was extremely deadly. But because most of the soldiers either died or were shipped off to war, it generally didn't spread and cause many casualties in the U.S. This was the first wave. The infected soldiers went to war and took the virus with them and it infected the whole battlefield in trench warfare. Thus it is referred to as the "Spanish Flu". But when it returned back to the U.S. in the second wave, it cause a high number of deaths before it eventually died out. This lead some individuals to theorize that the virus mutated. But IMHO, it was extremely deadly from day 1.

I was in a big box store yesterday and there was a pallet. It contain hundreds of boxes of face masks. As I recall each box contained about a hundred and they appeared to be surgical mask. And they were reasonably priced.

So it may be another sign that things may be winding down.

Citing Rise In COVID-19 Cases, Alameda County Officials Leave Current Health Order In Place

Quote:
Health officials in Alameda County on Friday confirmed that they would not be easing the current coronavirus shelter order as much of California progressed towards Stage 3 reopening, citing a recent spike in COVID-19 cases.

County officials cautioned residents that data indicated it would be unsafe to relax the requirements of the most recent health order that was issued on May 18.

“We currently have the highest rate of case increases in the Bay Area alongside a large increase in
hospitalized cases. It is imperative that we proceed with caution. In-person gatherings are prohibited at this time,” said the release issued by the Alameda County Health Department Friday.

Under the existing order, only essential businesses, outdoor businesses and activities and curbside and delivery retail allowed to operate. Outdoor vehicle-based gatherings are also allowed. A full list of allowed businesses is available on the Alameda County Health Department’s website


Alabama, Mississippi Coronavirus Cases Hit All-Time High as States Move Through Phased Reopening
Quote:
Alabama and Mississippi recently saw record highs in the number of coronavirus cases, as those two states move through their phased reopening plans.

On Friday, the Mississippi Department of Health reported a new single-day high in COVID-19 cases with 418, topping a previous high of 404 on May 8. This number brings the total number of cases in Mississippi to over 14,000, as well as at least 710 deaths.

In addition to Mississippi, Alabama also saw an increase in the average number of coronavirus cases over the past seven days. On Thursday, the state's department of health reported an average of 446 cases over the past week, which is a record high for the state.

According to the Alabama Department of Health, there were 406 new cases reported on Thursday, 464 on Wednesday, and 679 on Tuesday, which marked a single-day high number of cases reported in the state. This brings the state's total number of cases to over 16,000 as well as at least 605 deaths.

"We've had this week a couple of the highest days we've seen in number of cases, and that's certainly concerning to us," said Alabama Health Officer Dr. Scott Harris on Thursday.

So is this because there has been an increase in the infection rate or is it due to the fact that more people are being tested and as a result more positives are being recorded?

COVID-19 sniffing dogs are being trained by a company called 'Medical detection dogs'.

"If our research is successful, COVID-19 detection dogs could be deployed in public places such as airports and sporting events. Once trained, detection dogs could be deployed in airports or other venues to screen large numbers of people, providing a rapid non-invasive screening for COVID-19. A single dog can screen up to 250 people per hour"

Vietnam's contact-tracing effort was so meticulous that it goes after not only the direct contacts of an infected person, but also indirect contacts. "That's one of the unique parts of their response. I don't think any country has done quarantine to that level," Thwaites said.
All direct contacts were placed in government quarantine in health centers, hotels or military camps. Some indirect contacts were ordered to self isolate at home, according to a study of Vietnam's Covid-19 control measures by about 20 public health experts in the country.
