How the omicron spreads and what works
All of you first need to know how the Covid Omicron virus spreads. Evidence suggests:
A: inhalation of a wide size range of aerosols (including small <5 micron) at close proximity
B: inhalation of small aerosols that remain suspended in room air at a distance (>2m)
C: small risk of direct exposure to large droplets at close proximity
D: small risk of exposure through face touch following contact with contaminated surfaces 2/
Emission of virus increases with coughing, sneezing and vocal activities such as singing and loud talking.
Emissions are likely to be highest just at the point where someone turns infectious.
Hand washing and cleaning only does D. Important but probably a small component of risk.
Distancing is good for C and A, but won’t take away all of the risk and doesn’t work if your role means you have to get close
Screens do C and a bit of A but only for some specific cases
Ventilation and air cleaning is good for B and a little bit of A and is especially important if you share a room with others for longer periods of time. It’s not 100% though and it may be hard to mitigate very highly infectious cases.
Masks are good for A, B, C and D. They can mitigate droplets and large aerosols, reduce surface contamination and prevent you touching your face. They can reduce emission of all aerosol sizes. But as protection, especially at close range, only FFP3 mitigates smallest aerosols
The LocalCircles mask compliance report presents the ugly reality. The Govt must circulate to all and have them enforce mask discipline. The Govt data is outdated and small sample says 60% India is mask compliant which is wrong.

Start penalising people without mask .All get together, cross roads & shopping places should have police standing to catch the violators & heavy fines to be imposed. Do it on alternate days.You can't play with human life. more

The Peoples who are writing the scary information, should submit their thesis to any Overseas University. They will get PhD . This is the News media effect & experiment that peoples can control through Media, social media. & it is get successful. . The Load Circles should stop such propaganda write up on Social media. more

Carona Virus came and every one seems to have become an expert in dealing, researching, and giving insane comments regarding the same. If one just follows the simple guidelines set by the Government of wearing masks, maintaining social distancing, washing hands often and not going out unnecessarily, no Virus will come near you. more

Ms Seema Verma post is good information to understanding the spread of virus. At the same time Mr Shekar Natesh advise to follow Govt. guideline is sound and the best way of avoiding the virus infection more

I don't understand how common man is to be benefitted with the knowledge on how Omicron spreads. Let this spread the benefit of following covid protocols among the public which will help them and the government in tackling the issue. So please be constructive without wasting time and energy of the members. This is the drawback of democratic setup. more
