A baby from the Chinese city of Wuhan, the epicenter of the epidemic, was diagnosed with the new coronavirus 30 hours after birth, the Chinese state press reported on Wednesday.
The baby is the youngest person infected with the virus, which has killed nearly 500 since its emergence at the end of last year.
CCTV cited experts who said it could be a case of “vertical transmission”, referring to infections transmitted from mother to child during pregnancy, delivery or immediately after delivery.
The mother had tested positive for the virus before giving birth.
The official Xinhua news agency reported on Monday that a baby born last week to an infected mother had tested negative.
China’s national health commission said on Tuesday that the oldest person diagnosed with the virus is 90 years old and that 80% of recorded deaths were in patients aged 60 and over.
