A seven-month-old infant in Shanghai who has been infected with the novel coronavirus is currently receiving medical treatment and is in stable condition at a local hospital, the Shanghai Municipal Health Commission said on Tuesday.

The baby, together with her mother and maternal grandfather, were among the latest to test positive for the virus on Monday. Her father and her maternal and paternal grandmothers tested negative for the novel coronavirus but are still under medical quarantine and observation, the commission said.

The infant's maternal grandparents arrived in Shanghai from Hubei province's Wuhan city on Jan 20. The entire family, including the girl's paternal and maternal grandparents, gathered for two family dinners in late January, said Zheng Jin, a spokeswoman with the commission.

On Feb 2, the girl's paternal grandfather became the first confirmed case in the family.

There have already been several cases of infants across China getting infected with the virus. A 1-month-old baby girl in Guizhou province in the southwest was the youngest confirmed case in the country.

On Jan 30, a woman infected with the novel coronavirus gave birth to a healthy baby girl in a hospital in Harbin, Northeast China's Heilongjiang province. The newborn tested negative for the virus after two examinations.
