COVID COVID-19 Coronavirus Containment Efforts

I would be more concerned with the travel conditions from home to the beach and back. Personally, I would avoid airline flight right now. Close quarters with lots of strangers has no appeal to me. I have no issue driving myself.

We're planning on driving without any stops except for gas.

 

[Vanadium 50]

It's up to you, but as you describe it I think the bigger risk is travel (including rest stops) than the destination.

I have a question about vacationing these days. My wife and I are considering renting a condo on the beach that doesn't appear to be in a crowded area. We would not be going to restaurants but would cook all of our meals in the condo. On the beach, we would stay well away from others even if we have to drive to a less populated area nearby. Obviously, there is risk the minute you leave your home but I think this would limit our exposure as much as we can. Thoughts?

Do you have masks (medical mask preferably, for when you need to go to shops)?

Wash your hands well with soap and water before touching your face, flossing etc.

Not for a few years yet but my mother-in-law lives with us and she is in her 80's. We definitely don't want to bring it home.

You can safe distance from your mother-in-law for 2 weeks after you get home.

Thank you all for the input. I appreciate it.

Some of the nation’s leading public health experts are raising a new concern in the endless debate over Coronavirus testing in the United States: The standard tests are diagnosing huge numbers of people who may be carrying relatively insignificant amounts of the virus.

Most of these people are not likely to be contagious, and identifying them may contribute to bottlenecks that prevent those who are contagious from being found in time. But researchers say the solution is not to test less, or to skip testing people without symptoms, as recently suggested by the Centers for Disease Control and Prevention.

Instead, new data underscore the need for more widespread use of rapid tests, even if they are less sensitive.

Your Coronavirus Test Is Positive. Maybe It Shouldn’t Be.
The usual diagnostic tests may simply be too sensitive and too slow to contain the spread of the virus.

We're planning on driving without any stops except for gas.

I just did 2900 mile (4666 km) over 4 days. I mostly stopped for gas, but occasionally used a rest room, or went inside a shop to buy food. Most people were wearing masks, and most places had signs posted about wearing a mask and maintaining distance inside the establishment. Outside, many people were not wearing masks. It is a matter of using good judgement.

At three hotels, the front desk counters had some kind of plastic shield, and in one case, a table set in front of the counter (about 6 foot distance from customer to hotel employee), and I signed the paperwork on the table.

Interesting, thanks @nsaspook

The PCR test amplifies genetic matter from the virus in cycles; the fewer cycles required, the greater the amount of virus, or viral load, in the sample. The greater the viral load, the more likely the patient is to be contagious.

This number of amplification cycles needed to find the virus, called the cycle threshold, is never included in the results sent to doctors and Coronavirus patients, although it could tell them how infectious the patients are.
In three sets of testing data that include cycle thresholds, compiled by officials in Massachusetts, New York and Nevada, up to 90 percent of people testing positive carried barely any virus, a review by The Times found.

"The prolonged viral shedding in sputum is relevant not only for the control of infections in hospitals, but also for discharge management. In a situation characterized by a limited capacity of hospital beds in infectious disease wards, there is pressure for early discharge after treatment. On the basis of the present findings, early discharge with ensuing home isolation could be chosen for patients who are beyond day 10 of symptoms and have less than 100,000 viral RNA copies per ml of sputum. Both criteria predict that there is little residual risk of infectivity, on the basis of cell culture. "

One wonders why the university turned to physicists to model the spread of the virus rather than people with expertise in epidemiology. Maybe epidemiologists wouldn't sign off on the plan? Or maybe the epidemiologists knew that the situation would be too difficult to accurately model whereas physicists are always overconfident in their ability to build a mathematical model (whether or not it produces accurate results).

If UIUC cannot prevent the spread of the disease throughout its student population even with a massive testing regime, this does not bode well for the likelihood of other universities to be able to hold in person classes.

State University of New York opened up campuses. One campus in Oneonta, NY has reported:

507 positive cases since the start of the fall semester,​

46 students in quarantine on campus,​

117 students in isolation on campus,​

and that is just one campus. Students, and maybe staff and faculty are bringing the Coronavirus to campus and spreading it.

https://suny.oneonta.edu/covid-19

As a result of the infections, SUNY Oneonta is sending all students home for the rest of the fall semester after hundreds of Coronavirus cases have been reported so far this school year.
https://abc7ny.com/suny-oneonta-college-covid-on-campus-reopen-new-york/6405321/

Another smaller campus has seen more than a doubling of cases to 50 students, but no faculty or staff! In other words, the students are bringing the Coronavirus to campus and infecting the rest of the community.

Perhaps the same reason that the President's Task Force on COVID Virus appointed a neuroradiologist as Chief they wanted someone that will support their goals.

One wonders why the university turned to physicists to model the spread of the virus rather than people with expertise in epidemiology.

I suppose it's because physicists are pretty good at developing models like this. Plus the article didn't say the models were developed solely by physicists or without input from others. It just said Goldenfeld contributed to the reopening plan.

From the article, I didn't get an impression there was some misguided political agenda driving the university's decisions. It sounds like they underestimated the stupidity of a small number of students.

Out of 6500 students, do I see that right? Almost 10% got it?

A quarantine can at best help against out-of-state cases but does nothing to prevent spread among people who were in the state already.
There are also different rules how this works in households with multiple people. In some places they need to join the quarantine I think, in some places they don't have any restrictions. But even if they have to join a 14 day quarantine: Let person A infect person B after a week, and you can easily get someone who leaves the quarantine while being infectious.

It sounds as if they overestimated the civic-mindedness of students.
https://www.npr.org/sections/corona...me-doubles-down-on-discipline-amid-case-spike
"Wednesday's letter to students called out specific cases in which students had failed to work with local health officials on contact tracing, and one instance where a student posted a video to social media attempting to show how to manipulate the campus app that tracks testing results. About 100 students and organizations are facing discipline — including suspension — for behavior over this past weekend, including for hosting parties and for breaking quarantine, according to the note sent to students."

 

[Astronuc]

New York imposed a 14-day quarantine. Is it not working?

I don't know the answer. It's not clear, but I believe that anyone testing positive must quarantine for 14 days, at least. Anyone traveling to NY State from one of many restricted states must either show a negative test result or must quarantine, and perhaps be tested. I don't know how that is enforced except for those arriving at a port of entry, e.g., an airport. If one is passing through a state on the restricted list, the quarantine does not apply, if one spends less than 24 hours in the state. Apparently, they have not considered if one travels through 8 restricted states over 3 days.

To me it seems obvious. It was not because they were students, it was because they were drunk. The modelers didn't model intoxicated people.

The whole purpose of social drinking is to lower inhibitions. That leads to loud voices, no masks, and no social distancing. The government action that could have a positive effect would be a ban on public consumption of alcohol, in bars, on beaches, in parties, and all other settings. Not total prohibition, but a more restrictive ban.

If that didn't work, then a ban on parties of any size, public gatherings, or total prohibition would be the next more drastic step.

 

[Astronuc]

Out of 6500 students, do I see that right? Almost 10% got it?

About 500 students out of 6500, or about 7.7% of the students.

SUNY had elaborate plans for 64 campuses. https://www.suny.edu/campus-reopening/
That affects a little over 400,000 students, based on enrollment last autumn. https://www.suny.edu/about/fast-facts/

Each campus has their own plan.
SUNY New Paltz reports on 6 active cases and 1 recovered. https://www.newpaltz.edu/coronavirus-info/
The student population is 6807 undergraduates and 950 graduate students; faculty 344 full-time and 323 part-time. https://www.newpaltz.edu/about/glance.html

I don't know what testing is done before students arrive, and it's possible that testing and other precautions vary among the 64 campuses.

Pre-kindergarden, Kindergarden and grades 1-12 are supposed to start next week. Some learning will be done online, but I'm not sure how uniform that will be across the system.

That doesn't explain students who hosted, not just attended, parties when they knew they had tested positive.

SUNY Oneonta

I looked a bit at the student demographics. It's 99% in-state, and it's about a 50-50 mix of suburban New York (particularly Long Island), which has one of the highest infection rates, and upstate, which has one of the lowest. It also has a reputation as a party school.

The putative point of a quarantine is to separate the infectuous from the uninfected. Well, it used to anyway. This plan is to bring people from across the state, mix the infectuous with the uninfected for a few weeks, and then send everyone back into their communities.

It might be they only intended to allow those who have tested negative to leave campus.

"Although SUNY Oneonta’s recent policy does not allow students to leave for home without the approval of the county health department, Ms. Dimonda said that her parents were able to pick her up on Monday, the day she was put in quarantine. She said she was now “stuck in my room” on Long Island."

While downstate New York has had many more total Coronavirus cases, recently, the virus has been spreading slightly faster in upstate New York than downstate New York:

Apr 27, 2020 — Governor Andrew Cuomo offered some mixed news for Upstate New York in his daily briefing Sunday.

On one hand, he said state data found the rate of COVID-19 infection is now slightly higher in Upstate New York than in the New York City metro area. "Upstate the infection rate is one person infects .9. Downstate one person is infecting .75."

https://www.northcountrypublicradio...bove-downstate-but-reopening-could-start-here

Data from the NY Times also suggests the average daily new cases per capita in the past week is similar between upstate and downstate counties:

https://www.nytimes.com/interactive/2020/us/new-york-coronavirus-cases.html

Note that the county with the highest rate of new infections (the bright orange spot in the middle of the state) is Otsego County, home of SUNY Oneonta.

I wonder whether the combination of colder fall weather plus the mixing of people as college students get sent to campus and then sent back home will drive another wave of spread in the coming months.

 

[Vanadium 50]

, the virus has been spreading slightly faster in upstate New York than downstate New York

And if they keep mixing people from Long Island and upstate, it will spread even faster!

 

[russ_watters]

That's all fun, but note that the positivity rate hasn't been above 1% in New York State since the first week in June.
