Studies corner

[Branster]

There are so many snippets of information regarding small tests, case studies and even research from all over the world, some interesting, some surprising, some hopeful. Too many and too small or sometimes obscure to make the main news

If you’d like to share you are welcome to join the thread.

I’ll make a start with these findings from Canada about a potential inhibitor drug

Coronavirus SARS-CoV-2 spreads more indoors at low humidity

Indian-German research team recommends at least 40 % humidity in public buildings
< and presumably good in private homes too >

Low humidity study really interesting and possibly extremely useful.

Interesting paper looking at the designing the best strategy for dealing with Covid-19 in the long term. Uses the age of those with positive ab tests to predict the future course of the disease. Some unexpected findings. One of the lead authors is on twitter @fredericolois and is an interesting and challenging follow.

@alreadytaken Could you point me to the part that says they were mostly infected outside school?

At least 17% were transmission at school, that's a minority.
