Baby born with COVID-19 antibodies from infected mother

Doctors are studying the impact of COVID-19 on pregnant women and their unborn babies in Singapore, where an infant delivered by an infected mother earlier this month had antibodies against the virus but did not carry the disease.

The ongoing study among the city-state's public hospitals adds to international efforts to better understand whether the infection or antibodies can be transferred during pregnancy and if the latter offers an effective shield against the virus.

The World Health Organization (WHO) says while some pregnant women have an increased risk of developing severe COVID-19, it is not yet known whether an infected pregnant woman can pass the virus to her fetus or baby during pregnancy or delivery.

A Singaporean woman, infected with the coronavirus in March when she was pregnant, said that doctors said her infant son had antibodies against the virus but was born without the infection.

"It is still unknown whether the presence of these antibodies in a newborn baby confers a degree of protection against COVID-19 infection, much less the duration of protection," said Tan Hak Koon, chairperson of the Obstetrics and Gynaecology division at KK Women's and Children's Hospital.

Doctors in China reported the detection and decline over time of COVID-19 antibodies in babies born to women with the coronavirus disease, according to an article published in October in the journal Emerging Infectious Diseases.

While there is evidence that transmission during pregnancy is rare, a small study in Italy suggested that it is possible, according to research published in the Nature journal in October.

Other studies have shown COVID-19 antibodies can be passed to a child via breastfeeding, while KK's Tan said there was evidence they could pass during pregnancy through the placenta to the baby.

Paul Tambyah, one of the city-state's leading disease experts, said it was encouraging that antibodies were present in the Singapore baby months after the mother's infection, adding to broader evidence that they offer some protection from the virus.

新加坡一孕妇感染新冠新生男婴自带抗体

新加坡一家妇幼医院近日证实,有证据表明,该国一名新生儿在出生时体内就携带新冠病毒抗体。这名新生儿的母亲曾在今年3月份感染新冠病毒并痊愈。

专家表示,虽然这名婴儿出生时就带有抗体,但尚不清楚这是否意味着婴儿对新冠病毒具有免疫力,或者这种免疫力会持续多久。
