The authorities arrived to find the baby having been wrapped in a blue and white cloth by local residents, but she was found by them with no clothes, food, or even a note, Meng said.

Doctors from the nearby Mianyang Central Hospital were called to check the child, who had no obvious birth defects, before taking her back to the facility.

Doctor Wang Xiaoshuang, head of the neonatal ward, reported that the girl had been put in an isolation incubator due to the risk that she may have contracted COVID-19.

Initial tests, however, suggest she has avoided the disease, but she continues to be monitored by medics.

It took Mianyang police less than 48 hours to identify the child's mother, Ms Xie, 24, through a DNA database before making an arrest, a statement on 10th March said.

A second DNA test confirmed Ms Xie as the child's mother, the authorities added.

Ms Xie told police she conceived the child out of wedlock and gave birth in her rental room in the early hours of 7th March.

She decided to abandon the child because she did not want her family to find out, the suspect told investigators.

Ms Xie has been remanded on bail due to the ongoing COVID-19 outbreak.

She is expected to be charged at a later date.
