Newborn triplets in Mexico have tested positive for coronavirus in an “unprecedented” case, according to Mexican health authorities.
Medical experts are currently investigating whether the disease could have been transmitted through the mother’s placenta during pregnancy.
Two of the babies, a boy and a girl, are in a stable condition in a hospital in San Luis Potosi state. The second boy is receiving treatment for a respiratory condition.
Contagion in multiple births had not been detected anywhere globally and so the case would be investigated, said a spokesperson for the state’s Health Safety Committee.
“It would be impossible for them to have been infected at the moment of birth,” said State Health Secretary Monica Liliana Rangel Martinez.
The parents are currently being tested, with authorities saying they may have been asymptomatic.
Mexico has recorded over 185,000 coronavirus cases and 22,584 deaths since the country’s first case on 28 February.
The triplets – born prematurely on 17 June in Mexico – all tested positive for coronavirus on the day of their birth.
