An Asahi Shimbun staff writer in Tokyo was confirmed to be infected with the new coronavirus, the company announced on April 4.

The woman in her 30s returned home on March 28 after noticing that she lost her sense of smell while working at the company headquarters in Tokyo’s Chuo Ward.

The reporter was recuperating at home but experienced fatigue on March 31. She took a polymerase chain reaction test the following day and tested positive on April 4.

Her last face-to-face interview with an individual from outside the company was on Feb. 23.

None of her colleagues and others who were working in the same office on March 28 has complained of fever or other possible symptoms.

The woman had often worked from home as part of company-wide efforts to prevent infections. Before March 28, she last reported to the headquarters office on March 23.
