1-Atlast penny has dropped!
CDC has accepted virus can spread by airborne route
'It is possible that COVID-19 may spread through the droplets and airborne particles that are formed when a person who has COVID-19 coughs, sneezes, sings, talks, or breathes' cdc.gov/coronavirus/20…
2-Now hopefully authorities will give due attention to ventilation which can be crucial in reducing indoor spread & reducing the risk of 2nd wave
3- @CNagpaul@DavidGWrigley@helenamckeown now @TheBMA must lobby NHSE NIHP to change PPE guidance to take into account airborne transmission of virus @TheBMA should now supprt enhanced PPE as a risk mitigation factor for at risk HCWs which has been present at @NHSNLaG since May
4- I have no doubt that @TheBMA will do everything to protect its members especially as the virus is spreading again. PPE guidance should be reviewed urgently
5-Accepting airborne transmission can occur will help in getting HCWs appropriate PPE. In my Dept everyone been using FFP3 masks since Pandemic started in OPD with no Dr +ive Ab test todate
1-Virus spreads through air especially indoor in areas of low ventialtion
Have a look at this thread if you want to know how you can check if ventialtion in an area is adequate.
Its really easy!
2-Every time you exhale CO2 is exhaled in air. You can use CO2 levels to see if room is filling with potentially infectious exhalations
CO2 level lets you estimate if enough fresh outside air is getting in
3-Last year in Taiwan tuberculosis outbreak at Taipei University was found out to be due to underventilated rooms. Rooms had CO2 levels⬇️3000 ppm.When air circulation was improved with CO2 levels⬇️600 ppm outbreak completely stopped
