A creative solution to protect health care providers at high risk of contracting the coronavirus amid the global shortage of personal protective equipment is attracting interest throughout the world, including in Japan.

The Aerosol Box, created and shared online by Lai Hsien-yung, an anesthesiologist from Taiwan, is a transparent box shielding a provider's face from aerosol particles contaminated by the virus while intubating an infected patient, many of whom develop respiratory failure.

"I felt that I was protected," said Takahiro Kusume, 32, a doctor on the front line of an anti-coronavirus team at a university hospital in Tokyo.
