Does repeated exposure to COVID after initial exposure increase the severity of sickness? |
- Does repeated exposure to COVID after initial exposure increase the severity of sickness?
- I read that coronaviruses are all zoonotic, they come from animals and now infect humans, are there any examples of the reverse, human native viruses that affect animals?
- When you successfully fight off a mutated pathogen via antibodies from a previous infection/vaccination (that have reduced effectiveness, but still get the job done), does your body create updated antibodies for the mutated pathogen?
- How is it possible to treat allergies by repeatedly presenting the antigene to desentize but when you vaccinate (and booster) an antigene presentation trains the immune system to fight said antigene?
- Can a fever actually turn the tide in an immunologic battle that the human body would otherwise lose without the aid of medicine?
- Can viral antigens detect dead virus?
- Why does an object become radioactive when in proximity to a radiation source?
- What are the chances of immediate reinfection with COVID-19?
- How many people have died from Omicron in the US?
- Do plants and any other objects (especially vehicles ) emit infrared (IR) and if they do what are the wavelengths?
- Where does your mind/memories go when you’re blacked out drunk?
| Does repeated exposure to COVID after initial exposure increase the severity of sickness? Posted: 04 Jan 2022 05:43 AM PST I've read that viral load seems to play a part in severity of COVID infection, my question is this: Say a person is exposed to a low viral load and is infected, then within the next 24-72 hours they are exposed again to a higher viral load. Is there a cumulative effect that will cause this person to get sicker than they would have without the second exposure? Or does the second exposure not matter as much because they were already infected and having an immune response at the time? Thanks. [link] [comments] |

| Posted: 03 Jan 2022 03:03 PM PST This question is geared towards the Omicron Covid-19 outbreak, but really extends to the immune system in general. After receiving a booster of the Covid-19 vaccine, your body will produce antibodies targeting the original strain of the virus. Even though the potency of the antibodies against the Omicron variant is greatly diminished, this is still thought to improve your defenses against the disease. I'm particularly interested in the case where your body easily defeats an exposure to Omicron due to a large abundance of antibodies from a recent booster. Will the body bother creating updated antibodies in this case? Or will subsequent exposures still carry risk of infection, especially as the level of antibodies in your system wane over time since receiving the booster? [link] [comments] |

| Posted: 03 Jan 2022 08:21 PM PST Read a lot about it but couldn't find an answer or a more proper subreddit to ask this, so hoping this doesn't get deleted. For clarity: can a fever be THE causing factor behind the human body winning an immunologic battle against an infection that would otherwise cause death or other permanent type of harm without the help of medical treatment? I know the question is very specific and it might be hard to find someone who knows the answer. If you provide a positive answer please specify against which pathogens does a fever actually enable a turning of the tides if you can. [link] [comments] |
| Can viral antigens detect dead virus? Posted: 04 Jan 2022 11:15 AM PST I have spent hours googling this, and while I've found many sources discussing how PCR tests have the ability to detect dead virus since they are looking for RNA which remains after the virus has died, I have not been able to find any definitive source that states that viral antigens will no longer detect virus after the virus has died.

| Why does an object become radioactive when in proximity to a radiation source? Posted: 04 Jan 2022 09:23 AM PST My understanding is that when you have a radioactive material, e.g. Uranium, it decays which causes it to emit high energy particles, i.e. ionizing radiation. But say for example you leave a piece of clothing next to said Uranium for some time, the clothing will then become a radiation source itself. So how does this work? Is the piece of clothing now decaying as well? Or are the high energy particles emitted from the uranium somehow getting trapped in the piece of clothing and then being re-emitted? Thanks!

| What are the chances of immediate reinfection with COVID-19? Posted: 04 Jan 2022 05:20 AM PST If you just recovered from covid and got exposed to the virus immediately after, what are the statistical chances for reinfection? Is it even possible. [link] [comments] |
| How many people have died from Omicron in the US? Posted: 03 Jan 2022 05:07 PM PST The only thing I can find through Google is from 12/21/21 that there was the first confirmed death from the Omicron variant in the US. Has there still only been one reported death from the Omicron variant? Where can I find the real data? [link] [comments] |

| Where does your mind/memories go when you’re blacked out drunk? Posted: 03 Jan 2022 01:52 AM PST Are there subconscious ways to get these memories back? What actually happens to them? Or is it like a recording device that just stops and you'll never see them again? [link] [comments] |
