The US and much of Europe is practicing extreme social distancing. I haven't had the opportunity to shake someone's hand in weeks due to the lockdown. In fact, I haven't touched someone that is not a part of my household in at least three weeks.

But Japan has been avoiding handshakes naturally since the start of the outbreak, which may have helped suppress transmission rates before they even knew the virus was spreading.

Wasn't Boris Johnson dismissing that advice only a couple of weeks ago and shaking hands of people?
