A nice tl;dr from the newsletter that doesn't seem to be in the article (in short form):

> Among the many insights:

> - symptoms start to develop very fast, on average about two days after contact with the virus

> - infection first appears in the throat

> - infectious virus peaks about five days into infection

> - at that stage, it is significantly more abundant in the nose than the throat

> - lateral flow tests are a reassuringly reliable indicator of whether infectious virus is present
