Although COVID-19 infections in some regions have increased slightly recently, the possibility of large-scale outbreaks occurring in the short term is small, a disease control official said on Wednesday.

He Qinghua, an official with the National Administration of Disease Prevention and Control, said during a news conference that China"s epidemic situation remains stable, but new infections appear to be gradually increasing in some areas.

"This month, the domestic epidemic hit its lowest level since December," he said. "But since the middle of this month, the daily number of new positive cases and their proportion in fever clinic visits have been rising a bit."

He said that newly infected cases are mostly made up of people who have never been infected, who are immunocompromised and whose immunity levels have diminished.
