SINGAPORE (Reuters) - Singapore’s health ministry confirmed four more coronavirus cases on Wednesday, including a six-month-old baby, taking its tally to 28.

Both parents of the infant, a Singapore citizen, have also been infected, the ministry said.

Singapore on Tuesday reported its first cases of citizens and residents who had contracted the virus without recent travel to China, where the outbreak first surfaced at the end of last year.
