Wuhan virus (coronavirus) arrives in the USA

[Anonymous]

Why aren’t children as affected by COVID19 as adults? Seems like there’s a clue there to a treatment or vaccine. I know when my daughter was in preschool and elementary school, she picked up all kinds of flus and colds that were going around. Before someone beats me up about it, I know COVID19 is not a cold. But could young children have some kind of immunity because they had another endemic coronavirus exposure recently enough that their immune system recognizes what antibodies to use against COVID19? So all those things kids catch may have given them some cross immunity to this? And older people being more removed from that kind of exposure have no immunity? Maybe parents of younger children will fare better since they probably caught whatever bug their kids brought home.

But not diagnosing patients. Looking at a broader view of where it may be and only when the patient is negative for the flu. Better than nothing for sure. But still woefully lacking.

"The labs probably won’t be testing each sample by itself, though. Shult says he expects that they’ll be told to mix multiple samples together to make it more efficient. Labs can do that because these samples aren’t being tested to diagnose individual patients; they’re only looking to see if the virus shows up in the population at all. Testing in batches is common in disease surveillance, and it’s used regularly in HIV surveillance, for example."

Interesting. I have never heard of this.

No, I don't think that's right (although I'm also not a scientist). I think it's that:
1) In the Western world, kids are less likely to have been exposed to date, because we are still seeing mostly exposure from business travel, so we don't really know yet how kids will be affected. And, really, who knows what's happening in China.
2) Old people are always the most affected because they have old lungs. Kids have young, healthy, non-smokers' lungs, for the most part, so can weather respiratory problems better typically.
3) For some viruses (like 1918 flu or SARS), they can trigger a cytokine storm in healthy people. We may be seeing that with COVID, with some of the very sudden severe illness/death in people "in their prime" -- like some of the medical personnel, or the 38-year old Italian who ended up in the ICU. As I understand it, the cytokine storm hits young adults the hardest, because they have the strongest immune systems. Little kids aren't as affected by that.

The widow of a retired soldier who recently visited stores on a southeastern base tested positive for the new coronavirus in the first confirmed case for the Army in South Korea, officials said Monday as the military went on high alert.

Schools on bases across the country also were closed for the rest of the week, according to the Department of Defense Education Activity.

I'm surprised they haven't already limited base access to active duty & dependents and necessary personnel. Admitting a South Korean citizen who still has US commissary privileges from her late husband doesn't strike me as a necessary risk we should be taking at this point.

So now is the thought that just being in the same area(in this case and entire base) as one person that simply went to a store and left mean there can be any outbreak? Is there something they're not telling us about transmission?

You do know that coronavirus can linger on solid surfaces for up to nine days, don't you?

Now think about how one uses a shopping cart, handles money, opens a door etc. Plenty of opportunities to infect, even though the main transmission mechanismis through respiratory droplets.

Source? I haven't seen this reported anywhere that wasn't pure speculation.

This is why China was destroying cash.

For those who think COVID-19 is just a flu, consider looking at this post taken from Reddit. Note that it is footnoted, but you have to go to the Reddit post itself to link to those.

Why SARS-CoV-2 is not just "the flu"


1. The virulence (R0) of SARS-CoV-2 is estimated between 1.4-6.49, with a median of 3.28[1] . This is much higher than the seasonal flu, which has an R0 of 1.3[2] . What this means is that SARS-CoV-2 spreads signficantly faster than the seasonal flu.

2. The Case Fatality Rate (CFR) of SARS-CoV-2 is at least 2-3%[3] . This is 20-30 times higher than the CFR of the season flu, which is around .1%[4] .

3. SARS-CoV-2 can be transmitted without the infected showing any symtoms[5] . This makes it much more difficult to control.

4. Roughly 20% of SARS-CoV-2 infections result in serious symptoms that require medical intervention[6] . This is more than 10 times the hospitalization rate of the seasonal flu[7].

5. Symptoms from SARS-CoV-2 can persist over a month[8] compared to the seasonal flu where symptoms typically tend to clear after 5 days[9] .

6. There is no vaccine for SARS-CoV-2[10] whereas people regularly get annual flu shots.

7. There is no herd immunity for SARS-CoV-2 which means that it can theoretically infect the entire population. See, for example, a Korean psychiatric department where the virus infected 99/102 people.

Now, consider the multiplicative effect that all of these attributes have for the virus. Compared to the seasonal flu, SARS-CoV-2 (1) spreads faster; (2) kills far more; (3) is harder to control; (4) requires use of far more medical resources; (5) for far longer a period of time; (6) has no effective treatment; and (7) can infect entire populations.

These factors mean that SARS-CoV-2, if left unchecked, is far more likely to overwhelm a country's medical infrastructure. Additionally, when medical infrastructure is overwhelmed, the CFR will skyrocket because we know that 20% of cases require medical intervention.

It doesn't take a genius to piece it all together. This virus is potentially devastating if containment measures fail. Far worse than the seasonal flu.

British Columbia's seventh case is closely related to its sixth case, which was imported from Iran.

14 more passengers from the diamond princess confirmed positive.

At this point the only people being tested by the CDC appear to be people from the cruise.

Why are they even bothering when they won’t test anyone else?

Yes s this just diamond princess people? I don’t view them as the same as general public cases.

Because if we had 80K deaths from the flu last season and no school closings, or other measures then the whole China ..world has less cov cases combined so far, let alone deaths. Maybe we just don't excite that easily?

Because you hope that the flu shot gives you immunity or a more mild case. There's no immunity or vaccine with this virus, so I think people feel helpless.

You also need to look at the age distribution of that 80,000. Sadly, people probably react less if it's mainly hitting people over >80 years of age with other significant health issues. With the new virus though we are hearing about 29 year doctors and whole households dying.

“Whole household” of old/elderly.

1/5 of people require hospitalization, 1/20 ventilation. These numbers are an order of magnitude worse than the flu. And it seems to spread as easily.

They are practising social distancing (closing schools etc) because if they don't slow the spread of the disease, hospitals will end up with about 10 or 50 times as many patients as they can accommodate. At which point the death rates start skyrocketing.

Based on what data?
