Coronavirus COVID-19 - Global Health Pandemic #50

[Trident]

I assume you are being facetious.

In this thread we have discussed from the beginning what precautions we each take. Some take much more radical steps than I do when shopping, but I have never felt the need to reply as if it was overkill. Because I support each of us doing what makes us comfortable.

I miss the thread being more like it was in the beginning where we were simply supportive of each other when we discussed what kinds of changes we were making.

I feel the need to reply because the sun is still shining, the stars are still in the heavens and life is going on for all of us posting here. I guess more brightness, less negativity to everything would make everyone feel better, and there are many reasons to feel better.

Yeah, there are troubles, problems, warnings, but after a while I prefer to get out in the sunlight, which btw seems to be a help against this virus, or so I've heard.

 

[nhmemorymaker]

Is there any kind testing they could devise, to see if these recovered patients can reinfect others, months later if they test positive still?

i call that one of the million dollar questions.

Those are the types of docs like @katydid23 that I admire sooooooooooo much. They then also turn around and say "I'll look into", and they DO IT. I'm sure many are just as confused as we are, and look to their associations for guidance they release e.g. the Heart Association paper. https://www.ahajournals.org/doi/10.1161/JAHA.120.016509

I have to call my doctor about a prescription issue---and I am going to ask if they have any email address so I can send THEM the Dr. Suheut and Dr. Hansen videos. They are NOT pulm docs, so even they can learn something!

I can't fathom what will be done in the future as to increases in rates for federal and state taxes, not to mention insurance costs next year and in the future due to this to butress the shortfalls.

The elephant in the room, and I haven't seen ANY MSM or anyone speaking of such yet.

Has anyone here seen and I just missed it, or could share when they come upon such? TIA

I haven't seen any coverage about how we're going to refill coffers, but I think that will eventually become a topic.

Personally, I think the recovery will happen, but slowly. In the long run, I see the potential for greater than ever stability as priorities personally and nationally have, hopefully, been reset because of this crisis. In the short term, I think progress will be slow because people will be reluctant to spend.

Update on concerns about recovered patients in China testing positive again up to two months later:

Chinese doctors in Wuhan, where the coronavirus first emerged in December, say a growing number of cases in which people recover from the virus, but continue to test positive without showing symptoms, is one of their biggest challenges as the country moves into a new phase of its containment battle.

Those patients all tested negative for the virus at some point after recovering, but then tested positive again, some up to 70 days later, the doctors said.

Many have done so over 50-60 days.

The prospect of people remaining positive for the virus, and therefore potentially infectious, is of international concern, as many countries seek to end lockdowns and resume economic activity as the spread of the virus slows.

Currently, the globally recommended isolation period after exposure is 14 days.

So far, there have been no confirmations of newly positive patients infecting others, according to Chinese health officials.

China has not published precise figures for how many patients fall into this category. But disclosures by Chinese hospitals to Reuters, as well as in other media reports, indicate there are at least dozens of such cases.

In South Korea, about 1,000 people have been testing positive for four weeks or more. In Italy, the first European country ravaged by the pandemic, health officials noticed that coronavirus patients could test positive for the virus for about a month.

Reuters reported that one man in Wuhan, who appeared to be in his 50s, was still testing positive for Covid-19 more than two months after he first contracted it.

He had been treated at two hospitals before being transferred to a quarantine centre set up in a cluster of apartment blocks in an industrial part of Wuhan.

“I really can’t take it anymore,” he said.

How the relief bill deals with Covid-19 testing

A section-by-section analysis of the relief package says that the $25 billion amount for testing will go toward "necessary expenses to research, develop, validate, manufacture, purchase, administer and expand capacity for COVID-19 tests."

Of the total amount dedicated to testing, there will be $11 billion given to states and localities "to develop, purchase, administer, process and analyze COVID-19 tests." The rest of the money will be given to other entities, including federal agencies, to invest in promising new technologies and to distribute to labs.

FDA head: Second wave of coronavirus "certainly a possibility"

"The whole task force set of doctors is concerned about the second wave," Hahn told CBS. "That's why we have built into the plan the surveillance mechanisms to look for the respiratory illnesses and then to do the appropriate testing at that time."

Ancel Meyers said that Americans are largely staying at home and away from common places, which is why deaths are not continuing to skyrocket.

“That is the secret to success. That is why we have seen a trailing off of mortality in this country. And that is why it's going to be important going forward that we continue to take measures to prevent transmission by just keeping out of contact with each other or reducing the likelihood of transmission when we do have to come in contact with each other,” she said.

Is it safe to get a haircut right now?

Dr. Sanjay Gupta answered viewers’ questions about coronavirus on CNN’s New Day. Here’s what he had to say about haircuts as Georgia Gov. Kemp announced that some businesses, including hair salons, can reopen in the state starting this week.

[...]

“You can't keep a safe social distance when you’re getting your hair cut. … We may get to the point where people can get such rapid testing that we can know if people are infected or not, and that would help in terms of people being able to go out and do things like haircuts. But we're not at that point. We're not at that point here in Georgia or in any place in the country.”

US should focus on it's own tests, not comparisons to other countries, Dr. Sanjay Gupta says

[...]

" … You want to basically get a large enough sample size for the data to be meaningful. And you know what? I don't care about other countries, frankly. We keep saying, but we're doing more than other countries. It doesn't matter. That doesn't matter. There are countries doing better than us and there are countries doing worse than us in terms of testing. What matters right now here is here. And what we know is we need to be doing way more testing than we're doing. Maybe a million or so tests a day; I think we're around 150, 160,000 a day. And the reason you want to do that much testing is you get a better idea of where the virus is, how it’s spreading and how to contain it."

He is probably trying to figure out what to tell you.

My brother asked my Mom's cardiologist that same question about mom taking losartan and some other Blood Pressure drug. Should she keep taking them, even though she is in a retirement community, and could be at risk of the contagious virus?

My brother is a retired medical malpractice attorney, so he does know how to ask these questions precisely. Even then, he said the cardiologist was kind of hemming and hawing, and walking a fine line.

In summary:
On one hand, my mother does need these drugs to combat her hypertension, and at 89, she is not going to be able to make any changes or improvements on her own. Without them, she is at heightened risk for a stroke, or related heart issues.

HOWEVER, he did admit that there is not enough known yet, with certainty, about how these drugs interact w/the C Virus. There is some evidence that it could help the virus make it's way to the lungs. And yet other reports are that these same drugs help the patients fight the invasion of the infection, so it is a complicated situation, and he does not know the answer, at this time.

So his conclusion is that Mom needs to avoid having a stroke or a heart attack, first and foremost. So the best course of action is to shelter away from the virus and continue her medications.

Thank you. I expect my cardio to give me the same sort of answer. But maybe I could do more exercise and less stress (haha) could get my dose lower.

"Take Out Tuesday" to support local businesses. We have been doing our "due diligence" to support the locals. While I have not been overly hungry, I did take one for the team, and we forced ourselves to order a specialty house cured bacon and onion tart flambe yesterday. Made with creme fraiche.

Yum.

That's wonderful - glad to hear it's a community effort.

For my part, while I'm not ordering prepared food, I'm making a very deliberate effort to support local stores owned by individuals - grocery, bodegas, and pet shops - rather than ordering online. I'm happy to do it and to promote them as they have gone above and beyond to serve the community, being diligent with new safety requirements and putting serving our vulnerable neighbors safely as their priority. They have my loyalty forever, even as I stand outside the door in my mask at 6-foot intervals to wait my turn to get inside.

We each can do what we can for our communities, even if we do different things.

2 died with coronavirus in California weeks before 1st reported US virus death, health officials say

2 died with coronavirus in California weeks before 1st reported US virus death, health officials say



SACRAMENTO, Calif. (AP) — Health officials say two people died with the coronavirus in California weeks before the first reported death from the disease.



Santa Clara County officials said Tuesday the people died at home Feb. 6 and Feb. 17, with the first death in the nation from the virus reported on Feb. 29 in Kirkland, Washington. The Medical Examiner-Coroner received confirmation Tuesday that tissue samples sent to the U.S. Centers for Disease Control and Prevention tested positive for the virus, officials said.

I have been unable to find any articles that clarify the backgrounds of these early cases. I would think that would be open and available information to report. I want to know more.

Santa Clara County officials did not identify either of the two individuals who died, whether they had traveled to Wuhan or elsewhere, or whether they had contact with the few people who had been diagnosed with the disease before they died.

But reclassifying their deaths as related to the coronavirus suggests the virus had been spreading through the United States for much longer than was initially thought — potentially for weeks or even months longer.

First American coronavirus deaths took place weeks before initially thought

Abstract
During January 26–February 10, 2020, an outbreak of 2019 novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involved 3 family clusters. The airflow direction was consistent with droplet transmission. To prevent the spread of the virus in restaurants, we recommend increasing the distance between tables and improving ventilation.

From January 26 through February 10, 2020, an outbreak of 2019 novel coronavirus disease (COVD-19) affected 10 persons from 3 families (families A–C) who had eaten at the same air-conditioned restaurant in Guangzhou, China. One of the families had just traveled from Wuhan, Hubei Province, China. We performed a detailed investigation that linked these 10 cases together. Our study was approved by the Ethics Committee of the Guangzhou Center for Disease Control and Prevention.

On January 23, 2020, family A traveled from Wuhan and arrived in Guangzhou. On January 24, the index case-patient (patient A1) ate lunch with 3 other family members (A2–A4) at restaurant X. Two other families, B and C, sat at neighboring tables at the same restaurant. Later that day, patient A1 experienced onset of fever and cough and went to the hospital. By February 5, a total of 9 others (4 members of family A, 3 members of family B, and 2 members of family C) had become ill with COVID-19.

The only known source of exposure for the affected persons in families B and C was patient A1 at the restaurant. We determined that virus had been transmitted to >1 member of family B and >1 member of family C at the restaurant and that further infections in families B and C resulted from within-family transmission.

Figure. Sketch showing arrangement of restaurant tables and air conditioning airflow at site of outbreak of 2019 novel coronavirus disease, Guangzhou, China, 2020. Red circles indicate seating of future case-patients; yellow-filled red...

Restaurant X is an air-conditioned, 5-floor building without windows. The third floor dining area occupies 145 m2; each floor has its own air conditioner (Figure). The distance between each table is about 1 m. Families A and B were each seated for an overlapping period of 53 minutes and families A and C for an overlapping period of 73 minutes. The air outlet and the return air inlet for the central air conditioner were located above table C (Figure, panel B).


On January 24, a total of 91 persons (83 customers, 8 staff members) were in the restaurant. Of these, a total of 83 had eaten lunch at 15 tables on the third floor. Among the 83 customers, 10 became ill with COVID-19; the other 73 were identified as close contacts and quarantined for 14 days. During that period, no symptoms developed, and throat swab samples from the contacts and 6 smear samples from the air conditioner (3 from the air outlet and 3 from the air inlet) were negative for severe acute respiratory syndrome coronavirus 2 by reverse transcription PCR.

From our examination of the potential routes of transmission, we concluded that the most likely cause of this outbreak was droplet transmission. Although the index patient (patient A1) was asymptomatic during the lunch, presymptomatic transmission has been reported (1). Given the incubation periods for family B (Appendix Figure), the most likely scenario is that all 3 family B members were directly infected by patient A1. However, we cannot not exclude the possibility that patients B2 and B3 were infected by patient B1, the first family B member to become ill. For family C, a possible scenario is that both patients C1 and C2 were infected by patient A1; another scenario is that the patient C1 acquired the infection while caring for patient C2, beginning on January 27.

Virus transmission in this outbreak cannot be explained by droplet transmission alone. Larger respiratory droplets (>5 μm) remain in the air for only a short time and travel only short distances, generally <1 m (2,3). The distances between patient A1 and persons at other tables, especially those at table C, were all >1 m. However, strong airflow from the air conditioner could have propagated droplets from table C to table A, then to table B, and then back to table C (Figure).

Virus-laden small (<5 μm) aerosolized droplets can remain in the air and travel long distances, >1 m (4). Potential aerosol transmission of severe acute respiratory syndrome and Middle East respiratory syndrome viruses has been reported (5,6). However, none of the staff or other diners in restaurant X were infected. Moreover, the smear samples from the air conditioner were all nucleotide negative. This finding is less consistent with aerosol transmission. However, aerosols would tend to follow the airflow, and the lower concentrations of aerosols at greater distances might have been insufficient to cause infection in other parts of the restaurant.

Our study has limitations. We did not conduct an experimental study simulating the airborne transmission route. We also did not perform serologic studies of swab sample–negative asymptomatic family members and other diners to estimate risk for infection.

We conclude that in this outbreak, droplet transmission was prompted by air-conditioned ventilation. The key factor for infection was the direction of the airflow. Of note, patient B3 was afebrile and 1% of the patients in this outbreak were asymptomatic, providing a potential source of outbreaks among the public (7,8). To prevent spread of COVID-19 in restaurants, we recommend strengthening temperature-monitoring surveillance, increasing the distance between tables, and improving ventilation.

I have the same attitude....while at the same time have no appetite for take-out. I think it's safe and I truly want to support local businesses, but I still don't really want take out. I wish I did and I hope the appetite returns.

(In the meantime, my at-home appetite is more than active and fulfilled with too many homebaked goods. Had chocolate chip cookies for breakfast today.)

jmo

I feel the very same feelings---I just don't want take-out. And yet I truly want to support the locals. We have so many restaurants in our area, but only small restaurants in our town, no chains.

I am in a couple of groups where we collect supplies/donations etc for the more needy in our area, and we meet in a local church yard to collect and assemble.

So yesterday, I asked some of my friends "Who has really good takeout?" and "do we know anyone who really needs more business right now?" just to see if it would encourage my take-out appetite. It didn't. I'll try again later though.

I don't have the link, but at yesterday's White House press briefing, I thought I heard Mnuchin say that there is a website that provides transparency and shows the businesses that have less than 10 employees receiving a huge chunk of the emergency relief, it was an impressive amount.

EBM Below is the link to news article with quote from Mnuchin -

"We have over a million companies that have received this with less than 10 workers. There is very broad participation in really small business. I will comment there have been some big businesses that have taken these loans. I was pleased to see that Shake Shack returned the money,” Mnuchin said. “The intent of this was not for big public companies that have access to capital.”

"Mnuchin also said he wanted to give companies the “benefit of the doubt” by assuming they didn’t understand the requirements but warned of consequences for large businesses that take advantage of the program."

Scroll down at this link to read how it can cause severe ulceration in cat mouths and esophagus. Extreme caution should be used with anything that can cause this or blind you, IMO.

The Pros and Cons of Scrubbing With Betadine, Chlorhexidine - Veterinary Practice News

I would never use it to wash eyes and I have copy pasted the relevant bit from your link.

"But in cats, chlorhexidine can cause severe oral ulcers, laryngitis, pharyngitis and tracheitis. Besides direct application, these consequences can also occur after intubating a cat with an endotracheal tube that was washed with chlorhexidine (see photo). This can be prevented by not using chlorhexidine to clean small tubes, or by thoroughly rinsing them if chlorhexidine is used.

It can also occur after a cat licks a surgical site that had been scrubbed with chlorhexidine. This can be prevented by rinsing the skin postop and using an Elizabethan collar.

What is the best way to scrub the eye?
Chlorhexidine in any form and povidone iodine scrub cause corneal ulcerations. It is therefore recommended to use diluted povidone iodine solutions (0.2 percent), either made in-house or purchased as an ophthalmic preparation from your supplier.

The skin around the eye can be prepped as usual, but scrub or alcohol should never touch the eye. A generous amount of eye lube can be used to protect the eye from harsh chemicals. "

Here's the wiki about it. It often is used in human mouthwash.
