| Posted: 02 Apr 2020 12:39 AM PDT My question isn't whether it's hypothetically possible there was a small group of people back then, since we had our first confirmed case late January. I'm asking if it's possible that it had already started to spread in large scale that far back. I live in Los Angeles and late January my entire office started to get sick. Not everyone, but a good percentage of people on my floor. We had around 20 people in the office. 5+ people got sick within 2 weeks. Some mild, some a little more severe. I remember I got the "flu" and the fever lasted 3 days. I had a dry cough (which I never get. I'm a smoker and occasionally get bronchitis). I also didn't heal for over a week. I kept feeling sick and eventually got a mouth infection as my cough persisted. At the same time I was sick, the Human Resources assistant was out sick, and when she returned she had a sore throat and cough, mild fever, and red eyes. She was taking cough medicine. Here's the kicker. The HR director, was violently ill. She was out of office for over 2 weeks. Hospitalized after a few days of being sick. And it turned into pneumonia. She didn't return until over 2 weeks after her symptoms had started, and from my knowledge, they didn't know what was wrong with her. She was hospitalized a couple of days prior to January 20th if I'm not mistaken. Now the main question here is, is it possible she had corona and they didn't know or discover it even after she was hospitalized? Or would they have been able to conclude that since we at least knew about the corona during this time (but no active cases in the USA). I'd love to know a statistic on whether or not there was an abnormal surge in pneumonia cases in the country starting back then. I'm no conspiracy theorist, and would love a scientific opinion based on the details I provided. Thanks for reading. [link] [comments]  |
| Why is testing for Covid-19 considered so vital right now? Posted: 02 Apr 2020 12:26 AM PDT A lot of social media and journalists are up in arms over lack of testing, slower testing when compared to other countries, or not enough community testing being done However is it not fairly moot to test for it at this stage? There is no cure/vaccine etc outside of treating and caring for the symptoms, so knowing if someone has Covid-19 specifically won't help in the treatment of the complications that arise. And further as people are being advised to self-isolate and so on, the assumption would surely thus be if they are following the procedures whether they have it or not is irrelevant in the majority of mild cases, as just general recovery time is enough outside of complications. Is there something drastic I'm missing? [link] [comments]  |
| What actually happens when you “see stars”? Posted: 01 Apr 2020 03:14 PM PDT You see it in cartoons all the time and sometimes when I blow my nose too hard I see little points of light flying around my vision. What causes this and why do we see it? [link] [comments]  |
| How does Abbott’s 5 minute Covid-19 test work? Posted: 01 Apr 2020 09:18 PM PDT Abbott announced a new test for its ID NOW platform and can confirm the presence of Covid-19 in 5 minutes. There's a short video on their press release website that explains they "crack open" the genetic material of the virus and replicate it so it's detectable but that doesn't really explain anything about what's actually happening or how they are able to achieve a 5 minute test in a small box that can sit in a doctor's office compared to the existing tests which take many hours to complete and can only me done in medical laboratories.

| Posted: 01 Apr 2020 02:58 PM PDT I put "kills" in quotes since as a virus is isn't really "alive" to kill in the first place. To my knowledge, a virus is a big clump of RNA that doesn't really reproduce or use energy without a host. It's destroyed by soap because soap is an emulsifier and it pulls apart the lipids that make up the virus' "shell". When it's just sitting on a stainless steel doorknob, what makes it decay?

| Which species of dinosaurs became birds? Posted: 01 Apr 2020 07:14 PM PDT Obviously not all dinosaurs species continued to evolve and become birds. Do all birds have a single common dinosaur ancestor? Were they flying dinos just getting smaller and birdier? Are there a couple of separate lines of dinosaurs that became different kinds of birds?

| Posted: 01 Apr 2020 11:50 AM PDT My friend and I were talking about the effects of CO2 and he brought up a good point that CO2 has been really high in the past, but the ecosystems didn't collapse like we think they might from the recent spike in climate change. He is pretty anti-climate change, and I usually lean toward the side of most scientists. I just wasn't able to give him a good answer for his argument. My thinking was something like the rate of change in CO2 levels is much higher than it was millions of year ago and maybe the life forms had more time to adapt back then, but I'm not sure.

| Posted: 01 Apr 2020 06:35 PM PDT Does the fact that we don't have a vaccine for either illnesses despite 17 and 8 years having passed reflect on the likelihood of finding a vaccine for the current pandemic? [link] [comments]  |
| Posted: 01 Apr 2020 01:23 PM PDT It is known that fossils almost always happen through Sedimentary rocks. If not its ice or amber. But what about lava. Lets say a volcano leaked some gases which killed a herd of animals which has indeed happened before. The volcano erupts and sends a few lava rivers which cover the animals before the ash or other rocks can destroy them. Depending on how cool the lava is would it just destroy any possibility of a fossil? If lava rushed into a lake and covered all the marine creatures would any fossils be possible that way? I found a text book "Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils (but may, under special circumstances" What are those special circumstances?

| How do hand sanitizers work? (in chemistry terms) Posted: 01 Apr 2020 03:03 PM PDT I'd like to know how that magical -OH group gets rid of viruses and bacteria so easily, and how does its action compare to just soap and water. [link] [comments]  |
| What makes Covid-19 more contagious over common viruses? Posted: 01 Apr 2020 04:12 PM PDT I am not sure what is the answer, but I heard about virus mutating. If is because of the mutation, which part of the virus is different from others that make it contagious? [link] [comments]  |
| Why do we need a new flu vaccine every year? Posted: 01 Apr 2020 09:56 PM PDT Im not an anti-vaxxer, but I am wondering from a scientific point of view what is the reason why we need a new flu vaccine every year? I have heard that the flu mutates every year but how does it do this and why does it do this? Does the flu know when the sun does one revolution around the Earth and suddenly decides to mutate? Is it because the flu mutates as a result of updating the vaccines every year? Can you build a natural immunity towards flu so you don't catch it instead of having the vaccine? I have a few more questions regarding the flu vaccine and the mutation of the flu virus but I'm not sure if I am overstaying my welcome... [link] [comments]  |
