SEOUL, July 30 (Yonhap) -- For Kwon Ji-young, a 41-year-old office worker, traveling overseas has been an annual ritual that allows her to completely take a break from the heavy workload of her daily life.
But since she canceled her planned 10-day trip to Austria in April last year due to the COVID-19 pandemic, she has only browsed photos taken during previous trips in a bid to recollect fond memories.
"I don't know when I can travel overseas without virus concerns," Kwon said. "If I am fully vaccinated, I may be able to do so, but I am cautious about going abroad any time soon."
