Newborn triplets have all tested positive for coronavirus in Mexico, in what health authorities say is a previously unheard of case.
The babies were tested in the first hours of their life and hadn’t been in contact with anyone known to be infected with the virus.
Scientists believe they may be able to help shed light on whether the virus can be passed internally by pregnant mothers via the placenta.
"It is unprecedented from a scientific point of view," said Miguel Angel Lutzow Steiner, the head of the public health agency in San Luis Potosi.
Two of the babies are in a stable condition; the other is receiving treatment for a respiratory illness.
The health authorities believe the parents may have been asymptomatic – they have been isolated while they await results of their own tests.
