I taught a university course this last semester. In person. Up to 100 students in the lecture theatre. I managed to avoid catching #COVID19, or any kind of virus, actually. Here's the scoop: /1
#CleanAir: The lecture theatre was in a very old building, luckily it had windows. But they were up REALLY high, so I took my own ladder and climbed up and opened all of the windows. I also propped open the doors at the front and back. I warned the students to bring a jacket /2
This dropped the CO2 from around 2000ppm to around 700ppm in ~ 10 mins. I also ran an air purifier at the lectern, on full. I kept my mask on until the CO2 dropped below 800ppm. /3
I masked at the end of the class so students could come and talk to me. Most of them masked when they did this, without me asking. At one point I had almost 20% of the class testing positive for #COVID19. /5
@AndrewDickson13 Where do you get viraleze from in NZ? And is there an alternative? I've seen Flo travel nasal spray recommended because it has carrageenan in it.
@AndrewDickson13 Did you know Viraleze is in UK NHS trial as 7day covid treatment completed sept and results expected any day. It may well replace Paxlovid as treatment and SAFE, not absorbed into blood stream and much much cheaper.
@AndrewDickson13 We could start a trend …. 😂
