The DT yesterday (by its Global Health Security Editor!! rather than a jobsworth) reported on a Chinese study (157 cases and 2147 contacts) that showed 22% infection amongst friends, 18% in families, 12% on transport and "something in the 0-5% range" outside.
One might say "So what?" but this puts numbers on things. Another study showed 28% spouses infected - which prompts the thought - why not 100%?
All very interesting.
