1/ New study in @GlobalHealthBMJ suggests that mask use in the household can play a major role in reducing #covid19 transmission.
They found up to 79% reduction in household transmission if facemasks were used before symptoms started.

2/ They found no significant effect on reducing transmission if masks were used after symptoms started.
This supports the idea of invisible spread within households.
In the home, usually people have close contact w/ no masks.

3/ Secondary attack rate in the home here was 23%.
They also note the efficacy of cleaning/disinfecting the home.
Home based transmission is a big deal. Invisible spread in close indoor settings — we need to tackle this head on.

4/ For this reason, a number of countries have focused on central isolation options away from the home.
In the USA, we would never mandate this given human rights violations etc
But protection within the home is an area that has not been discussed much in our natl dialogue.
