Rising virus cases across Asia are reviving concerns over economic growth as potential lockdowns threaten to derail recovery and test the limits of central banks' accommodative policies.

Singapore shares advanced as much as 0.4% after five straight sessions of losses, while South Korea's KOSPI jumped to a two-month high.
