This is a very interesting study of what happened in China and how they got the epidemic back under control. Also supports what Shanghai has been saying.

To sum up though - the reason they won't work is not biology based but culture based. They would work if we did them.
Extract:
Aggressive “social distancing” measures implemented in the entire country included canceling sporting events and shuttering theaters. Schools extended breaks that began in mid-January for the Lunar New Year. Many businesses closed shop. Anyone who went outdoors had to wear a mask.
Two widely used mobile phone apps, AliPay and WeChat—which in recent years have replaced cash in China—helped enforce the restrictions, because they allow the government to keep track of people’s movements and even stop people with confirmed infections from traveling. “Every person has sort of a traffic light system,” says mission member Gabriel Leung, dean of the Li Ka Shing Faculty of Medicine at the University of Hong Kong. Color codes on mobile phones—in which green, yellow, or red designate a person’s health status—let guards at train stations and other checkpoints know who to let through.
“As a consequence of all of these measures, public life is very reduced,” the report notes. But the measures worked. In the end, infected people rarely spread the virus to anyone but members of their own household, Leung says. Once all the people in an apartment or home were exposed, the virus had nowhere else to go and chains of transmission ended. “That’s how the epidemic truly came under control,” Leung says
I think this is very interesting. We need to start restricting what we do, for the sake of our NHS being able to cope.
It also says 20% of cases (1 in 5) ended up in hospital. That is a lot worse than flu. 'moderate' cases could be those with pneumonia at home. I had pneumonia at home and lots of antibiotics. Took me 2 months to get over it.
I know it's a delay rather than cure but my biggest fear about delaying social distancing measures (and the blase attitude of a lot of people on facebook about curtailing their holidays etc) is that we'll run out of ICU beds for the 1 in 5. That's going to be a LOT more deaths than if we all get it gradually.
