I'm not a confirmed case, but I'm a 90% sure case based on symptoms and symptoms of people I have been in close contact with, and so far the experience has been relatively mild, in the literal sense. The primary discomfort has likely been the anxiety of how the tightness in my chest might progress (which ironically can also cause chest tightness). I'm in a low risk group. I had lethargy and high fever the first day o…

Note that I am not an M.D. But, consider getting a pulse oximeter. You can use it to assess your respiratory function (more) objectively. Anxiety and panic attacks can impact your oxygen saturation, but unlikely to do so to dangerous levels. Again, I'm not an MD. Maybe someone from the field of medicine can add their thoughts here.

Your comment made me want to get an Oximeter so i hopped on amazon right now.

One of these things just doesn't belong!!!

Isn't it the case that most countries in the world don't have enough tests, it seems only South Korea does. I live in Switzerland and they are also restricting tests to higher risk groups, and people with worse conditions (which is a bit grim, how dead do I need to be before I can get a test?) Either it's due to Olympics, or just logistics. Will the Olympics even happen if Japan is declared "OK" but many guest nation…

It's not really about how bad your symptoms get before you can get tested. It's about WHERE you are. Coronavirus is a virus after all, just like the flu, there is no medication. You can only treat the symptoms, but not the virus itself (as opposed to a bacterial infection where you can attack the bacteria with antibiotics). So with these undeniable facts it's fairly simple, if your symptoms are so mild that you can c…

Don't know why this is downvoted. Doctors can't treat the virus but only the symptoms, even for the flu.

From a public health perspective, if you have any symptoms, be it covid-19 or flu, just isolate yourself for the health of others.

Oh come on. A) nobody is making that claim - you are. So don't turn this into some weird non-fact-based appeal to emotions. The claim that they are useless is because the evidence does not support them. They ARE useful in clinical settings, and heavily required there. B) there is no evidence for their success: 1) https://www.bbc.co.uk/news/health-51205344 "implementing simple hygiene measures" was vastly more effecti…

Nobody is making this claim? Since your nickname sounds German, you may be able to understand this text from the FAZ: "Im Folgenden ist eine Reihe nachweislich falscher Angaben aufgelistet – etwa der Nutzen von Atemmasken gegen eine Ansteckung" Source: https://www.faz.net/aktuell/gesellschaft/gesundheit/coronavi... What they claim is that the uselessness of face masks is proven. Not that the usefulness is unproven. T…

For those who don't read German:

"In what follows, a series of provably false claims are listed - such as the use of breathing masks against contagion".

I wonder if this will be like H1N1. At first we only identified extreme cases and we had these terrifying reported fatality rates. Then we identify more and more mild or asymptomatic cases and the rates drop and drop. We’ve already seen how CFR was reported as 3 or 4%. Then on the cruise ship full of people over 60 it’s 0.7%. If there are lots of mild or asymptomatic cases it will likely be much lower. H1N1 was ident…

The WHO predicted that 150 million people would be killed by avian flu https://www.google.com/amp/s/amp.theguardian.com/world/2005/... Using the same logic that had lead to the severe predictions for cv19. For swine flu they promoted and stood by a CFR of 60%. Again turned out to be nonsense; nonsense known at the time to others https://jech.bmj.com/content/62/6/555.abstract

Both links are for H5N1 avian flu

You seem to be living in a different factual world than the rest of us, where ICU cases are in hallways and surgical suites is not "over capacity", and leaving people to die of suffocation without standard lifesaving treatment is not unusual.

I'm going to be giving up on this thread in a moment because people aren't even reading what I'm reading and definitely aren't answering in good faith. The original claim was that people over the age of 80 aren't being treated because they don't have the capacity for it. I queried if they were sure about that, because the Italian government was saying that's not true. An Italian has now replied to that same post also…

Lombardy is not the worst hit place so far. Wuhan is.

Let's talk about false positives: there seems to be no solid estimate regarding common Cov-19 tests. I've seen numbers from 40% to 85% in papers suggesting at least a high number, some of which will probably be sloppily classified as "asymptomatic" cases.

I read that the false positive rate is extremely low (below 1%).

False positives are not a huge problem when you are only testing people with symptoms. False positives would only become a problem when you are doing a large number of tests on people who have no symptoms (e.g. 1% of 1 million people when close to none have the virus).

I think your numbers are the detection rate: false negative rate is high (up to 40% for early tests).

I keep hearing “masks are useless”. If every person who has any cough or any chest tightness or any sore throat, however mild, put on a mask, wouldn’t that stop the spread? I live in Japan. It started here earlier but didn’t explode. Nothing is closed. Business as usual. everyone wears masks. Most cases in Hokkaido. Maybe because it is much colder there and easy to overexposed and tax the immune system.

It's useless in the sense that you can still contract the virus with a mask. Let's say they are using the surgeon's mask, someone can sneeze and it can get in through the side. The n95 has a better seal so that can prevent it, but what if someone sneezes and it gets into your eye. I would say some protection is better than nothing, but don't assume you will be protected from coronavirus 100%.

100% protection might be important to you personally, but it does not matter on a societal scale. What does matter is to decrease as much as possible the mean number of new people infected per sick person.

If that number is above 1, the growth is logistic (exponential in early stages), if it is lower but still above 1, it is exponential but with a longer doubling time ("flattening the curve"), and if it is below 1, cases will decrease.

> dry eyes Also no confirmed case here, but I attended a conference and later got an email that one participant tested positive. Since a few days, I also have dry eyes (thought it was because of dry heating air in our apartment first, but it didn't go away for days as it normally does, not even yesterday when we did not had the heating on because of the warm weather), dry cough and I am a little tired. 2 days ago I h…

Kind of sounds like allergies?

I live in Japan and I experience mild symptoms since last Wednesday but not sure if my symptom is due to Covid-19. In Japan, You have meet two conditions to take a CPR test. 1. the symptoms with fever of 37.5 degrees or more continue for 4 days or more (for the eldery and those with underlying disease, "4 days" becomes "2 days") 2. you have strong laxity (malaise) or breathlessness (dyspnea), or you have underlying d…

What would you change if you take the test and come positive?

Get a blood test. If CRP raised and lymphopenic, likelihood of ARDS requiring ITU admission is higher. This can happen very quickly after the first week, so I'd put pressure on the doctor to keep me hospitalized.
