Simply put, if I go out today (with the antibodies in me) and meet someone with Covid, can I still carry the virus back to my family members? |
Having "marker" antibody is one thing; having neutralising antibodies is quite another. This is a highly grey zone - the duration of protection conferred by infection. You're at a risk of re-infection from the same or variant strain, depending on YOUR immunity (not just measurable by antibody titres - T cells also have a significant role), and hence just as likely to transmit the infection to others, even if you remain asymptomatic.

As long as you're solo or with someone you live with, it's absolutely safe - for you and others around you, who may momentarily pass you by. Infact masks are not recommended at all during outdoor exercise activities with adequate physical distancing. Exercise is also meant to relieve stress - overthinking or being hypochondriac defeats this purpose anyway. This is the medical answer. The other answers are based on your personal choice and the restrictions imposed by law (& it's convenient misinterpretation).

Within 24 hours - highly unlikely. At least not on an immunological basis. Severe allergic reactions are possible within minutes to hours, but extremely rare - and lead to anaphylactic shock.

He won't be shedding viable virus post infection and unlikely to infect anyone else in that sense. However, he may get re infected (I hope not) and transmit the new viable virus even without developing symptoms himself, especially if protected by antibodies. So - hands, face, space - to continue.

But now, after vaccination we might still get the disease, albeit mildly, and we might still be able to pass it on. It's all better than nothing, but not nearly as good as hoped. |
If there were herd immunity for a respiratory virus, why would anyone need annual/seasonal flu vaccination? The answer is mutations. As long as there are mutations, there is no hope for herd immunity, unless the same vaccine confers equally protective immunity against all prevalent strains in the population at that given time I think, the UK, US and some other EU nations (much like India in Jan 21) might be celebrating the "defeat of covid" a bit too prematurely. Once the world opens up, it doesn't take much time for mutations to spread. And let's face it; the whole world is not going to be vaccinated against all prevalent, emerging and yet to appear variant strains atleast in the next few years. We just have to live with this.

Few thousands actually. One highly suspect reason is that probably people have been overdosing and even self medicating (during the current wave), given that this condition was never reported last year despite the same use of steroids (although strictly used that time only in the ICU/hospital setting) and majority of affected elderly population, who were more likely diabetic than the current young population being affected. This is the opinion of the treating doctors who extracted this history from such patients.

That said, outdoor transmission risk is significantly lower than indoor. |
Which respiratory infection is not "airborne"? What a ridiculous discovery by the CDC!
All respiratory pathogens are aerosolized during expiration (normal and forced - talking, coughing, sneezing) and remain suspended within "droplets" - once dry, they no longer remain viable. The size of droplets determines the distance of spread - smaller droplets will travel further, but ALSO will dry earlier and be non infective by then as compared to larger droplets at a closer distance. That's exactly the reason why outdoor transmission is significantly lower than indoor.
And finally on India's "exclusive" vaccination policy. Compare this with our own pulse polio campaign wherein millions of under 5 children used to be vaccinated over just 2 days, with the vaccine (also stored between 2 -6°C) was actually brought to their doorstep (or many convenient "polio booths") without any issue of pre registration. It's clear that every effort is being made to slow down the speed of vaccination to hide the lack of planning and foresight (& the vaccine itself) necessary and expected to conduct such a mass public campaign.
