“It also proves that their babies are at risk, even if their babies are not infected, they can be affected,” Jamieson noted during a call with reporters on Monday.
Increased risk of serious illness and death
For one of the reports, the researchers looked at data of 461,825 women between the ages of 15 and 44 who tested positive for Covid-19 between January 22 and date. October 3. They focused only on people who had experienced coronavirus symptoms.
The team adjusted for external factors and found that pregnant women were more likely to need special care, with 10.5 per 1,000 pregnant women being admitted to an ICU, compared with 3. 9 out of 1,000 women are not pregnant.
Pregnant women are three times more likely to need invasive ventilation aids than women who are not pregnant. Likewise, they are at a higher risk of needing to support the lungs and heart with oxygen.
They are also more likely to die, with 1.5 deaths per 1,000 pregnant women, compared with 1.2 per 1,000 women who are not.
In keeping with trends seen in the general population, the researchers found that certain races and ethnic minorities were even more likely to cause serious infections or illnesses. Among pregnant women, Hispanic women are 2.4 times more likely to die, and Asian and Native Hawaiian / Pacific Island women are at higher risk of hospitalization with the ICU.
The team notes that regardless of whether they are pregnant, women over 35 are more likely to have a more serious illness.
The likelihood of a pregnant woman becoming seriously ill may be due to physiological changes during pregnancy, including increased heart rate and decreased lung capacity, the researchers said.
“In order to reduce the risk of serious illness and death from COVID-19, pregnant women should be counseled about the importance of seeking prompt medical attention if they have symptoms and preventive measures. SARS-CoV-2 infection prevention should be emphasized to pregnant women and their families at all medical visits, including prenatal visits, “the research team wrote.
Risk of preterm birth and neonatal infection
One group studied the outcome of pregnancy and infant birth for 4,442 women diagnosed with Covid-19 between March 29 and October 14. Of the 3,912 live births, they found 12.9 percent. is premature birth. In comparison, the preterm birth rate accounted for 10.2% of the live births in the general population in 2019.
The CDC says that babies born too early have a high risk of death and disability, including problems with breathing, vision and hearing.
Of the infants tested for Covid-19, the team found 2.6% positive. Coronavirus infections are most common in infants whose mothers test positive for coronavirus within one week of birth.
About 60.6% of women experience symptoms, although the researchers say mothers’ symptom status does not affect the frequency of preterm birth in their newborns.
At least one underlying medical condition has been reported in 45% of women, the most common being obese.
Because 84.4% of women studied underwent Covid-19 during their third trimester, more research is needed to understand the effects of infection in early pregnancy and the long-term effects on with babies.
Researchers note that while severe Covid-19 occurs in infants, the majority of term babies born with Covid-19 have no symptoms or mild illness, the researchers noted.
Caution when using for pregnant women
“Less than 1% of pregnant women with Covid are admitted to intensive care,” says Jamieson. “However, they have an increased risk when you compare them to people who are not pregnant.”
Jamieson recommends pregnant women avoid gathering, wearing masks and social distance – even within their families, when needed.
“We are learning more about how people get infected and there is some new information that households come into contact with – so the people in your home – could be the source of the infection,” she said.
“It is not unreasonable to have a lot of work at work, for example, to let the person live separately from the rest of their family or to protect the rest of the family by masked or even secluded indoors., “she added.
“Pregnant women need to be put in different stages of vaccine testing, so that when there is a vaccine, we understand the safety and effectiveness of the vaccine during pregnancy,” she said.
Jamieson added: “It is really important that when there is a vaccine, a pregnant woman doesn’t have the chance to get it.
