Delivery service firms across the nation are implementing a raft of measures to mitigate the risk of infections amid the coronavirus scare as customers grow increasingly concerned that face-to-face package transfers may leave them prone to infection.

The delivery industry's apparent high-risk nature was highlighted by Sagawa Express Co.'s announcement Monday that one of its drivers — a male employee in his 60s working in the Nagoya area — tested positive Sunday night for COVID-19. The firm said it is investigating customers who may have come into "close contact" with him so appropriate steps can be taken.

Delivery giant Yamato Transport Co. said last week that amid the rapid spread of the virus nationwide, it will temporarily introduce a drop-off system that allows customers the option of receiving a package without coming into the proximity of drivers.
