Three premature newborn siblings have tested positive for coronavirus in an unprecedented case in Mexico.
One of the triplets, a boy, is receiving treatment for a respiratory condition, while his brother and sister are said to be in a stable condition.
All three remain in hospital in the San Luis Potosí , following their premature births on Wednesday, June 17, local health authorities report.
Medical experts are investigating whether the babies could have been passed coronavirus through their mother’s placenta during pregnancy.
A spokesperson for the state’s Health Safety Committee said contagion in multiple births had not been detected anywhere globally and so the case would be investigated.
A very small number of newborn babies have been known to pick up the virus after birth, but health officials say they do not believe this is what happened in this case.
State Health Secretary Mónica Liliana Rangel Martínez said: “It would be impossible for them to have been infected at the moment of birth.”
However, the parents are currently being tested, with authorities saying they may have been asymptomatic.
Mexico has seen 22,584 people die from coronavirus since the first case was reported there on February 28.
Earlier this week a 13-day-old baby died in the UK from coronavirus, NHS England reported.
The infant, who had no underlying health conditions, is one of the UK’s youngest victims since the start of the coronavirus pandemic.
