The director-general of the World Health Organization said he doesn’t recommend the handshake replacement of bumping elbows to avoid spreading the coronavirus.

“When greeting people, best to avoid elbow bumps because they put you within 1 meter of the other person,” Dr. Tedros Adhanom Ghebreyesus tweeted on Saturday. “I like to put my hand on my heart when I greet people these days.”

The US surgeon general last week urged elbow-bumping.
