Newborn triplets in Mexico have tested positive for coronavirus in an “unprecedented” case, local health authorities report.
Medical experts are looking into whether the disease could have been transmitted from the mother’s placenta during pregnancy.

Two of the babies, one boy and one girl, are in a stable condition in a hospital in San Luis Potosí state.
However, the second boy is receiving treatment for a respiratory condition.
A spokesperson for the state’s Health Safety Committee revealed that 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 Mexico 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 recorded more than 185,000 coronavirus cases and 22,584 deaths since the country’s first case on 28 February.
Coronavirus in newborns
The triplets – born prematurely on 17 June in Mexico – all tested positive for coronavirus on the day of their birth.
Coronavirus in newborns is unusual, but not unheard of. Babies can contract the virus after birth if they have close contact with anyone who is already infected. Coronavirus might also be passed on in the womb from mother to baby via the placenta.
US researchers from Yale School of Medicine recently reported the first known case of placental infection with coronavirus. When infection does occur, the risk to mother and baby is often low – although some reports suggest it might increase the likelihood of babies being born early.
There is no evidence that the virus causes miscarriage or affects how your baby develops in pregnancy, but, as a precaution, pregnant women are advised to be strict about avoiding close social contact to reduce their chance of getting coronavirus.
If they do become infected, most mums-to-be will have mild or moderate symptoms and recover. Babies may show no signs of the illness at all. If you are caring for a baby, you can reduce their risk of getting the virus by keeping your hands clean with regular hand washing.
