A study of a pregnant woman who underwent an emergency cesarean section and her newborn showed that the fetus had been infected with novel coronavirus in the womb, Swedish researchers reported in the British Journal of Obstetrics and Gynaecology.

According to Swedish media reports, the pregnant woman was admitted to Skane University Hospital in southern Sweden last year with acute abdominal pain and had symptoms that appeared to be corona-like.
The doctor’s examination found that the fetus in the pregnant woman’s body has a weak heartbeat and other problems, immediately performed an emergency cesarean section.
Both the mother and the newborn tested positive for Novel coronavirus in subsequent tests.
‘There is a lot of evidence that the baby was infected while in the womb,’ said Dr. Zaigam of Skane University Hospital, who was involved in the study.
Studies of the placenta, for example, have shown that viral proteins are present in many of these places, and that the placenta is infected at both ends of the fetus and the mother, causing widespread inflammation and other problems that affect its functions such as providing nutrition to the fetus.
The environmental evidence is that the baby required breathing AIDS because of preterm birth and other problems, was taken away immediately after the birth by cesarean section, was not with the mother, and all the health care workers contacted were negative for the coronavirus test, which also suggests that the baby was infected while in the womb.
Genetic sequencing of virus samples taken from mothers and newborns also showed that both were infected with the same virus.
But a few days after birth, researchers found a mutation in the virus in the babies.
The surprising timing of the mutation may have been linked to postnatal exposure to a different external environment than the mother’s womb, the researchers said.
The researchers say this suggests that pregnant women infected with novel coronavirus can also infect their fetuses in the womb, exposing them to health risks.
While it is rare globally for a fetus to become infected with COVID-19 in the womb, there may be a need to rethink how the health of pregnant women with suspected or confirmed COVID-19 is monitored.
Novel coronavirus may affect the health and aging of infants, the study found
Chile, the third edition times website published on November 13, 2020, entitled “will be coronavirus will affect how the next generation? 1918 pandemic may be helpful in understanding the influence of the reported that researchers at the university of southern California, according to a study recently published in the exposed to will be coronavirus might affect unborn people’s health and aging.

In this article, the university of southern California professor Leonard Davis institute of gerontology erin kerry cummings, caleb, leonardo Da Vinci and neonatal medical researcher at the keck school of medicine, Molly easterlin, pointed out that by the end of 2020, the infection will be coronavirus mothers will give birth to about 300000 babies, there are millions of babies are born in suffered great pressure because of the outbreak and emotional impact in the family, even if they are no one in the family of the new champions league infection.
While the long-term effects of novel coronavirus on infants have not been found, Dr. Fincher said, researchers can draw information from past experience, such as the 1918 flu pandemic and the 2012 Middle East Respiratory Syndrome.
“The 1918 pandemic had a long-term impact on people who were in a fetal state at the time, dying at a younger age in adulthood and having higher rates of diabetes, ischemic heart disease and depression after age 50,” Fincher noted.
From that perspective, Fincher added, “the COVID-19 outbreak could have long-term effects on a group of people conceived during the outbreak due to maternal infection and environmental stress.”
Maternal viral infection can affect the fetus in a variety of ways, ranging from direct transmission through the placenta to inflammatory responses that alter metabolism in the womb and negatively affect fetal development.
While direct mother-to-child transmission of the virus and severe birth defects were rare during the COVID-19 outbreak, there was an increase in premature births and low birth weight during the 2009 H1N1 influenza outbreak, possibly as a result of increased inflammation.
‘Although the work on novel coronavirus and pregnancy is still in its early stages, there are already some disturbing results that merit further study,’ the authors write.
An increased rate of preterm delivery may be associated with maternal infection with novel coronavirus, and other studies have suggested that an increased risk of fetal death is also associated with coronavirus.
Other potential risks, including increased risk of blood clotting due to pregnancy and severe COVID-19, also require further study.
Easterlin, stressed that “we suggest, in order to discover the womb virus exposure to child development and the influence of adult health, the study of epidemic during neonatal consideration should be given immediately to collect on mother and fetus, newborn and placenta data”, and added that these initial data on children’s development, after the “should cooperate with health, behavior and cognitive function of lifelong study”.
In addition to the immediate risks posed by infection, the COVID-19 pandemic has increased levels of stress, unemployment, food insecurity and domestic violence, and has led to a reduction or disruption of antenatal care.
For these reasons, the researchers recommend that studies of the population conceived during the epidemic should include uninfected mothers and children and compare this population with children born before and after the pandemic, as well as cover a variety of socio-economic measures.
