#Covid cycles will recur till Govt, Busniess Orgs, NGOs & Public, understand & rigorously follow/enforce rules: (1) #Hygiene/hand wash, (2) #Mask/face covering, (3) #Distancing, (4) #Ventilation (virus filtr/UV radiation of recirculated air), (5)#TTQ (testing, tracing, quarantine

2/gpe An application of this👆🏼 learning to https://t.co/NCYwB5lHw5

3/gpc Proof that ventilation of public toilets/bathrooms or UV-C sterilization of its AC recirculated air, is critical to reducing risk of spread ( also other spaces like kitchens) https://t.co/oRUb1KKxtc

4/gpc Indian #Serum tests reveal ~60% infection in slum & one room tenament areas of Mumbai & Pune. This means there is only 20% points more to go for herd immunity. But, people living in more prosperous areas, will have to b v careful for 6-9mos. Beware of bars. Protect old,sick

2/gpc #Covid A nice graphical representation of the precautions, all citizens of the world will have to take, for a year to defeat the Corona Virus.

5/gpc Check out #Ventilation (at #4) in first tweet above

6/gpc And a graphical chart of level of covid risk under different conditions(#Masks, #Distancing, #Ventilation). I would add that #PublicToilets, even in airports, are highly risky!

7/gpc If the 5 precautions at top of thread r followed by all citizens (+ extra care of Sr citizens) then no lockdown is needed; Only rational application of these principle; by compulsion, if people don't listen. Besides hygiene, clean/fresh air in public bathrooms is critical

8/gpc #Ventilation Air conditioned spaces need #UV_C filter

9/gpc Intensity of exposure to Corona virus matters. Which is why all household members get sick if they don't take precautions during home quarantine of one member. It's also why bars, party rooms & public bathrooms are most dangerous.

10/gpc This means we will have to follow the five safety precautions mentioned in first tweet & repeated in 🧵, even after new cases decline(ie for 6-12 months) : bit.ly/2FB7mZa

11/gpc The five fold path out of Covid19 #Masks, #Hygiene, #Distancing, #Ventilation/#UVfilteration , #TTQ

12/gpc As #Air #conditioning generally dries out the recirculated air it's even more important to treat the air with #Ultra #Violet filters which kill Corona Virus in the #AC system. Rooms with individual ACs (or poor circulation)can use ceiling #UV-C lights which also kill virus

13/gpc Unless we learn and apply the lessons outlined 👆🏼in this🧵, the wily👇🏼SARS Coronavirus 2, is going to keep beating us 🙈🙉🙊💩

14/gpc Article👇🏼Supports the conclusions reached in 👆🏼🧵 trib.al/5coOggA

15/gpc #Masks (triple layer cotton mask is good for hot climate, in colder climate a synthetic middle layer may improve protection)
