Covid Variant Omicron (B.1.1.529)

In summary: There's an "extremely high number" of mutations in this variant, some of which could make it more transmissible or undermine the effectiveness of vaccines. UK Health Secretary Sajid Javid has announced that six African countries will be added to the UK's red list from tomorrow at noon local time. Flights from South Africa, Namibia, Lesotho, Botswana, Eswatini and Zimbabwe will be temporarily banned and UK travellers will be required to quarantine.This variant stands out because it contains more than 30 changes to the spike protein - the SARS-CoV-2 protein that recognizes host cells and is the main target of the body's immune responses....

Admittedly mortality statistics is not my area of expertise. That being said, I am aware that determining cause of death is typically based on the primary medical condition that can be linked to the mortality cases. The tricky issue is when a particular patient with a serious co-morbid condition (e.g. cancer) contracts COVID-19 and then subsequently dies. It is possible that cause of death could be listed as both cancer and COVID-19.

Are there adjustments made to account for extra deaths? I'm not entirely certain about this.
This kind of approach. 29 countries. The methods are too technical for me
NZ does well though, I understood that much!

As an aside regarding Omicron, a few colleagues had COVID19 over Xmas. In their 30s jabbed and boosted.
Colleague one said it was like a cold, runny nose and sore throat. No headache, fever, aches and she did not feel ill as such.
Colleague two felt bad for 72 hours then ok. Mild flu.
Anecdotal.
Today our PM has given instructions to frontline workers in terms of testing BUT No lock down (yet) BBC briefing today at 6.00pm.
218,000 cases in 24 hours with 54 deaths.
Thursday is usually the highest for cases, numbers, hospital and deaths.
Usually.

Well in my case having the Pfizer shot gave me a renewed long Covid , just a bit smaller and shorter and with different symptoms than the one I had after the real infection so I guess the outcomes vary.

The Omicron variant may not be attacking the lungs as severely as Delta or other variants, but it apparently is still making some people (those with other illnesses/diseases) quite ill, and some potentially fatally so.

There were 5,495 people hospitalized with COVID-19 in New York City, as of Monday, official statistics show — four times the amount from two weeks ago and higher than any point since May 2020.
https://www.msn.com/en-us/health/me...-a-different-way-an-er-doctor-says/ar-AASsrPq
I can't readily find numbers for the rest of the state. In the published data, since the beginning of 2022, New York State has reported deaths in lowest age groups (0-9, 10-19, 20-23), which was rare during the last two years. It remains to be seen if the mortality of children, youth and young adults has increased this month.

Elsewhere, Mucio Kit Delgado, assistant professor in Emergency Medicine at Penn Presbyterian Medical Center emergency department, said on Twitter on Monday that he had seen a "strikingly consistent pattern" in symptoms based on vaccination status.

Delgado said that he "hardly saw anyone who had gotten a booster because if they caught COVID-19 they're likely at home doing fine or having regular cold/flu-like symptoms."

Meanwhile, when people were vaccinated but not boosted, he said he found many patients were "wiped out, dehydrated and febrile." Delgado said that people who were older than 55 or had other medical problems were often admitted overnight for intravenous fluids and "supportive care", but usually went home within a day or two.

Finally, Delgado said that in his experience, unvaccinated people were "the folks that get sick and had to be hospitalized because they need oxygen." "Some even younger than me," he said.

So, get vaccinated and boosted!

CDC mortality data (https://covid.cdc.gov/covid-data-tracker/#demographicsovertime) says there is a potential six week delay in reporting, so we may have to wait to get reliable estimates on the mortality of the current Omicron wave. The NY state hospitalization data above, however, shows an increase in hospitalizations for ages 0-17, which was not observed during the wave last winter.

I found the hopitalization data for NYS, but not by age group.
https://coronavirus.health.ny.gov/daily-hospitalization-summary
As of yesterday, there were 10,411 Covid patients hospitalized, with 5,495 in NY City (52.8% of state total), the hardest hit area. So I was premature in my previous post, I could find the numbers, but not by age group.

For mortality - https://health.data.ny.gov/Health/New-York-State-Statewide-COVID-19-Fatalities-by-Ag/du97-svf7/data - but that is just those died under some kind of medical/patient/elder care. There is nearly 13,000 others who died outside of a medical or care facility that aren't included in the statistics.

Code:
 Fatalities (Cumulative values) ascribed to COVID (SARS-Cov-2)
Age group   12/01  12/31  12/03
 30 to 39    590    625    630
 20 to 29    177    191    195
 10 to 19     17     22     24
  0 to  9     17     18     19
In early December, the lowest three age groups were at 17, 17, 177 until 12/06, when someone in the 10-19 age group died. Toward late September, the mortality rate increased. And the rates increased further during the first 3 days of January. Particularly in the 0-9 and 10-19 age groups. While young folk are less vulnerable, they are still vulnerable, especially if unvaccinated, which was the case for the youngest age groups until recently, when vaccines were authorized/approved for 5-11.

Also we do not treat viral flu infections with drugs. Not at the minute,
We do have drug treatments for influenza. I was prescribed, and I took, Tamiflu (Oseltamivir Phosphate), which arrested my symptoms due to influenza within 24 hours. That was the one year in the last 10 that I didn't get vaccinated.

Oseltamivir is used to treat some types of influenza infection ('flu') in adults, children, and infants (older than 2 weeks of age) who have had symptoms of the flu for no longer than 2 days. I received Tamiflu within 24 hours of onset of symptoms. It is better to be vaccinated than to become infected, since the infection means inflammation of tissue, e.g., cardio-pulmonary system, which may shorten, or end, one's life.

Oseltamivir is in a class of medications called neuraminidase inhibitors. It works by stopping the spread of the flu virus in the body. Oseltamivir helps shorten the time that flu symptoms such as a stuffy or runny nose, sore throat, cough, muscle or joint aches, tiredness, headache, fever, and chills last. Oseltamivir will not prevent bacterial infections, which may occur as a complication of the flu.

I'm not familiar with https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwjQ-rGgtZv1AhXoYnIKHS8yAPAYABABGgJxdQ&ohost=www.google.com&cid=CAASE-Ro-mPoBY90a93xpgkoatf5tYI&sig=AOD64_3k9juhTxtTu1Sp0KXGSLC_IJE4fg&adurl=&q=. It's relatively new.
https://www.cdc.gov/flu/treatment/baloxavir-marboxil.htm

I've been getting the influenza vaccine for some time now in order to protect my mother-in-law, my parents, my children, and now my wife, who has also been getting influenza for some time, since she was her mother's primary caregiver, until her mother was confined to an elder care facility and subsequently died (old age, and about as natural as one who basically gives up on living and stops eating and drinking). My wife and I, and our adult children, have all received the SARS-Cov-2 vaccines and boosters, and we get the influenza vaccine annually as well.

I am aware of several sources of data showing that severe cases and deaths are reduced by the vaccine (e.g. the vaccine clinical trials and various real world observational studies), but I don't think I've seen the data about vaccination reducing the incidence of long COVID. Do you have a link to the study showing this data?

But not from the vaccine.

[Deleted quote from another member]

There's some wiggle room in that wording, meaning you are claiming either the vaccine gave you "long covid" or worsened an existing condition. To be clear, "long covid" is not a Covid infection, it's failure of damage to quickly heal, with long-term symptoms. Vaccine reactions may have similarities in symptoms, but the vaccine can't give you covid, much less "long covid".

I currently have "long throat infection" on top of "long sinus infection" but it would not be accurate to say the throat infection caused the sinus infection to come back, even though the symptom is the same (dry cough).

What I was getting at is that whilst vaccinated the virus can still get into your body, all you have to do is be in close contact with an individual who has the virus.
I was not suggesting the vaccine gives you covid.

Even though my original post is now gone, and some raised alarms over it, I can and want to say that I was unclear in what I said and therefore got taken out of context ,
@russ_watters @pinball1970 No I do not think and have never thought that you can catch Covid from the vaccine. Clearly the vaccine does not have the full virus parts in it to be able to do anything like that.
So I hope we won't have to come back to this point and I;m sorry for being lazy about my wording.

It seems you have understood my now deleted post the way I actually meant it.
Yes my opinion was along the lines of Dr. Pollard in that we once tried to catch Covid , (catch as in get on top and stop it) with the vaccination program , clearly due to various factors like slow rollout at certain places, hesitancy , and leakiness of the vaccine itself we now understand that we won't be able to eradicate Covid by simply vaccinating so it seems that a combination of herd immunity/infection and vaccination will be the future. I said that adding to this maybe we should focus on a variety of good ways to have certain drugs at our disposal and have them cheap if possible to be able to treat Covid so that it is mild and short even for the vulnerable, therefore also limiting the risk of new bad mutations coming along.
Also I check the local Covid statistic and some from the vulnerable risk group are dying even with the vaccination so they too would probably benefit from an additional shield in case they get the infection
They used remdesivir here and still do but in limited numbers both due to the nature of the drug and mostly due to cost

It seems that what happened with Omicron is that as we were still in the process of vaccination it just came along most likely from a patient or patients that were not vaccinated , it seems to me that if we only rely on vaccination we will still not be able to reach the full scope of people (also due to hesitancy) who are at risk of getting Covid (everyone essentially) and therefore the risk of new variant coming along is still high. Maybe having good antiviral drugs that can treat infection and make it short/shorter could help us in this regard.
Basically it would do no harm for us to have a first aid kit type of solution where we have such drugs "on the shelf" at our disposal whenever we need them being given by a family doctor or at hospitals etc.
The key takeaway here is to have a treatment that is easy to use and widely available , indeed I agree with @Astronuc that whenever the flu vaccine "misses" having a TAMIFLU or another drug helps and goes along way. I've used such myself and they have helped a great deal.

The province of Ontario in Canada has re-imposed public health restrictions (e.g. closing restaurants for indoor dining, closing gyms, limiting capacity in retail stores) to try to slow the spread of the Omicron variant, as well as dramatically ramping up booster shots. Other provinces in Canada have taken similar measures.

I MIGHT HAVE COVID NOW:

I went to get my regular A1c diabetes blood sugar test today. Woman next to me kept coughing and said she had body aches. Said she was at the doctor's office for COVID test, b/c her colleagues at her secondary school all got COVID and she was exposed. She was next to me for 45 minutes at least and chatting (sometimes to me and sometimes to people on other side of her) and coughing. I honestly considered leaving. She did honestly tell us she thought she had COVID...I am vaxed and boosted and didn't want to come back another day for my blood test...I was double-masked and kept turning my head away from her.

I have a cough now...but I don't it'd be from catching her COVID right just 30 minutes later?

She was masked?

For ill patients, especially respiratory illnesses, my doctor's office has people call when arriving for an appointment and waiting in one's car until the staff are ready. The doctor's office does not want people in the office any longer than necessary to do whatever checks and tests are required for diagnosis. Sick patients are placed in a different wing of the doctor's office away from those getting checkups or other diagnotics who are otherwise healthy.

Pfizer recently developed a protease inhibitor drug that showed about 90% efficacy at preventing hospitalization from COVID-19:
Earlier this month, Pfizer released results of a study of its treatment in 2,246 Covid patients who were at high risk of developing more severe disease because of risk factors such as being over 65, overweight, or having cardiovascular disease. Patients were randomly assigned to receive a five-day course of either Paxlovid and a second drug, ritonavir, or a placebo. Among those who received Paxlovid within five days of developing symptoms, eight, or 0.8% of the total, were hospitalized. In the placebo group, 66, or 6.3%, were hospitalized. That meant overall Paxlovid reduced the risk of hospitalization by 89%. No patients who received Paxlovid died, compared to 12 who received placebo.
https://www.statnews.com/2021/12/22...to-treat-covid-19-in-patients-as-young-as-12/

Unlike remdesivir, which needs to be administered intravenously, Paxlovid can be taken orally in pill form. Although the drug received FDA authorization for use as a COVID-19 treatment, supplies may be limited initially as manufacture scales up. The hope is that combined with widespread vaccination, the combination of the two could hopefully lower hospitalization and mortality rates to a level where normal, pre-pandemic life is possible again.

For more discussion of the drug see this PF thread: https://www.physicsforums.com/threa...ew-anti-viral-drugs-to-treat-covid-19.992545/

I went to an Urgent Care center, had a 2 hour wait (in my car), and then my own curtained room so I was never near any of the many surely COVID positive patients for more than 30 seconds. But I was still nervous. Fortunately I'm past the time where I could have been infected there.

Today, NY State reported 84,202 (second highest value) new confirmed positive cases for SARS-Cov-2 and 131 deaths attributed to COVID-19, including 1 child 0-9 year age group.

So far in the first 5 days of this year the number of deaths attributed to COVID-19 are as follows:
Code:
Age group   01/05/2022
90 and Over     91
80 to 89       131
70 to 79       122
60 to 69        94
50 to 59        58
40 to 49        19
30 to 39         8
20 to 29         6
10 to 19         2
 0 to  9         2
-------------------
   Total       533

Until mid December, NY State would go months without deaths in the two youngest age groups, and one or two months without deaths in the 20-29 and 30-39 age groups. That has changed to daily or every other day with the current surge of infections.

New York passed 3 million infections cumulatively on 21 Dec, 2021, and the state will pass 4 million infections on 7 January (in 18 days), if not tomorrow.

This urgent care office SUCKED.

They kept the waiting room well socially distanced, but the line out the door was horrible. We stood in the winter cold for over an hour in a line out the front door and people were within 1-2 feet of each other. The woman coughing next to me was mostly 1 foot off the back of my neck. She only told her COVID story about 30-minutes after being in line and coughing and talking to us and I immediately wanted to run away from her. I thought it'd be rude, but also had already waited so long that I just wanted to get my A1c test done today, b/c I'd have to come back another day and wait yet again if I left.

No curtains, no nothing to separate the masses. Many places let you wait in the car as you take a ticket number or something. This office just let people pile into a huge line out the door that was not very socially distanced, which negates the indoor waiting room distancing. Dang woman should have SHUT UP if she thought she had COVID. Talking increases risk of spreading it. ...so, yeah, I'm nervous, given I am diabetic and all.

She was masked, but she was the WORST. Kept talking and talking and saying how Biden is ruining the country and got into conspiracy theories. If she KNEW she had body aches, was coughing, and a bunch of her secondary school teacher colleagues caught COVID, I feel she had a social-medical obligation to SHUT UP and not spread it potentially by talking.

The ONLY excuse I can think of is if COVID was warping her mind. Some drugs can make people talkative and I think COVID could maybe affect people's thinking too and maybe make them less self-aware and talkative. I recently took a drug that made me super talkative (prednisone) and my doctor and pharmacist said it's a common side-effect - it changes one's personality and even makes people sometimes get mentally confused.

It's possible COVID had a mental affect on this woman. Otherwise, she was freaking irresponsible!

I flunked a Covid test five days ago. I still haven't felt a thing. I'm 66 years old.
Failing is the goal here. :wink:

Sorry, I hope it goes ok for you.

Was this an antigen test? Please remember
  1. The positive predictive value (PPV) varies with disease prevalence when interpreting results from diagnostic tests. PPV is the percent of positive test results that are true positives. As disease prevalence decreases, the percent of test results that are false positives increase.
    • For example, a test with 98% specificity would have a PPV of just over 80% in a population with 10% prevalence, meaning 20 out of 100 positive results would be false positives.
    • The same test would only have a PPV of approximately 30% in a population with 1% prevalence, meaning 70 out of 100 positive results would be false positives. This means that, in a population with 1% prevalence, only 30% of individuals with positive test results actually have the disease.
    • At 0.1% prevalence, the PPV would only be 4%, meaning that 96 out of 100 positive results would be false positives.
    • Health care providers should take the local prevalence into consideration when interpreting diagnostic test results.

This urgent care office SUCKED...
Sorry to hear that. Must be local/cultural differences. Mine was orderly and well-spaced out.
