COVID-19 infection in pregnancy is associated with several pregnancy complications. [1] However, pregnancy does not appear to increase the susceptibility of becoming infected by COVID-19. [2] Recommendations for the prevention of COVID-19 include the same measures as non-pregnant people. [3]

Effect of COVID-19 in pregnancy

COVID-19 in pregnancy [1]
Complication Odds ratio 95% confidence interval
Pre-eclampsia 1.331.03 to 1.73
Preterm birth 1.821.38 to 2.39
Stillbirth 2.111.14 to 3.90

According to a systematic review and meta-analysis in 2021, COVID-19 is associated with stillbirth, pre-eclampsia and preterm birth. [1] According to the same review, compared with mild COVID-19, severe COVID-19 is strongly associated with preeclampsia, preterm birth, gestational diabetes and low birth weight. [1]

A review in 2022 suggests that pregnant women are at increased risk of severe COVID-19 disease, with an increased rate of being hospitalized to the intensive care unit and requiring ventilation death, but was not associated with a statistically significant increase in mortality. [4]

A systematic review update in 2022 demonstrated that pregnant women are at increased risk of severe COVID-19. It also found that risk factors for severe COVID-19 in pregnant people included high body mass index, being of an older age, being of non-white ethnic origin, having pre-existing comorbidities, having pre-eclampsia or gestational diabetes. [5] [6]

A 2023 meta-analysis concluded that COVID-19 infection at any time during a pregnancy increases the risk of maternal dealth, severe maternal morbidities and neonatal morbidity, but not stillbirth or intrauterine growth restriction. [7] Unlike earlier reviews, this study did not find a link between COVID-19 infection during pregnancy and increased risk of stillbirth at or beyond 28 weeks' gestation. [7] This study used the first large set of pregnancy cohort data from sub-Saharan Africa. [7]

Recommendations

Prevention

The World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) of the United States advises pregnant women to do the same things as the general public to avoid infection, such as covering cough, avoid interacting with sick people, cleaning hands with soap and water or sanitizer. [3] [8]

Vaccination against COVID-19 was not associated with an increase in miscarriage or reduction in live birth. [9] Meta-analysis has not identified any pregnancy-specific safety concerns with vaccines. [10]

The data overwhelming support maternal vaccination as being effective at reducing the risk for infection and severe illness. [10]

Studies seem to show that completion of a two dose mRNA vaccination during pregnancy reduces hospital admissions for COVID-19 among infants under 6 months, but there is insufficient evidence for how long protection continues for an infant after birth. [10]

The WHO states that pregnant women can receive covid-19 vaccines and, if not already vaccinated, should have access to WHO Emergency Use Listing-approved vaccines, as the benefits of vaccination during pregnancy outweigh potential risks. [10] The Royal College of Obstetricians and Gynaecologists in the UK strongly recommend vaccination in pregnancy and prefers that the Pfizer-BioNTech or Moderna mRNA vaccines are offered where available due to greater amounts of data on that vaccine type. In America, the CDC, the American College of Obstetricians and Gynecologists and Society for Maternal-Fetal Medicine encourage pregnant women to get COVID-19 vaccines. [10] The Federation of Obstetric and Gynaecological Societies of India recommend vaccination, though it is not currently recommended by the Government of India. [10] More than 80 countries do not currently recommend that all pregnant and lactating women should be vaccinated. [7]

Treatment

A state of the art review published in 2022 stated that the basic principles of diagnosing and managing COVID-19 should be the same for pregnant patients as for non-pregnant patients. It recommnended that treatment with corticosteroids should be modified to use non-fluorinated glucocorticoids and that Il-6 inhibitors and monoclonal antibodies could be used, as could specific antiviral therapies. [11]

Pregnancy is not a contraindication for therapies including respiratory support with oxygen, non-invasive ventilation, ventilation in a prone position, intubation and ventilation, and extracorporeal membrane oxygenation. [11]

Miscarriage, also known in medical terms as a spontaneous abortion, is the death and expulsion of an embryo or fetus before it can survive independently. The term miscarriage is sometimes used to refer to all forms of pregnancy loss and pregnancy with abortive outcomes before 20 weeks of gestation.

<span class="mw-page-title-main">Stillbirth</span> Death of a fetus before or during delivery, resulting in delivery of a dead baby

Stillbirth is typically defined as fetal death at or after 20 or 28 weeks of pregnancy, depending on the source. It results in a baby born without signs of life. A stillbirth can often result in the feeling of guilt or grief in the mother. The term is in contrast to miscarriage, which is an early pregnancy loss, and Sudden Infant Death Syndrome, where the baby dies a short time after being born alive.

<span class="mw-page-title-main">Fifth disease</span> Medical condition

Erythema infectiosum, fifth disease, or slapped cheek syndrome is one of several possible manifestations of infection by parvovirus B19. Fifth disease typically presents as a rash and is more common in children. While parvovirus B19 can affect humans of all ages, only two out of ten individuals will present with physical symptoms.

<span class="mw-page-title-main">Pre-eclampsia</span> Hypertension occurring during pregnancy

Pre-eclampsia is a multi-system disorder specific to pregnancy, characterized by the onset of high blood pressure and often a significant amount of protein in the urine. When it arises, the condition begins after 20 weeks of pregnancy. In severe cases of the disease there may be red blood cell breakdown, a low blood platelet count, impaired liver function, kidney dysfunction, swelling, shortness of breath due to fluid in the lungs, or visual disturbances. Pre-eclampsia increases the risk of undesirable as well as lethal outcomes for both the mother and the fetus including preterm labor. If left untreated, it may result in seizures at which point it is known as eclampsia.

Labor induction is the process or treatment that stimulates childbirth and delivery. Inducing (starting) labor can be accomplished with pharmaceutical or non-pharmaceutical methods. In Western countries, it is estimated that one-quarter of pregnant women have their labor medically induced with drug treatment. Inductions are most often performed either with prostaglandin drug treatment alone, or with a combination of prostaglandin and intravenous oxytocin treatment.

<span class="mw-page-title-main">Influenza vaccine</span> Vaccine against influenza

Influenza vaccines, colloquially known as flu shots, are vaccines that protect against infection by influenza viruses. New versions of the vaccines are developed twice a year, as the influenza virus rapidly changes. While their effectiveness varies from year to year, most provide modest to high protection against influenza. Vaccination against influenza began in the 1930s, with large-scale availability in the United States beginning in 1945.

<span class="mw-page-title-main">Complications of pregnancy</span> Medical condition

Complications of pregnancy are health problems that are related to, or arise during pregnancy. Complications that occur primarily during childbirth are termed obstetric labor complications, and problems that occur primarily after childbirth are termed puerperal disorders. While some complications improve or are fully resolved after pregnancy, some may lead to lasting effects, morbidity, or in the most severe cases, maternal or fetal mortality.

<span class="mw-page-title-main">Nutrition and pregnancy</span> Nutrient intake and dietary planning undertaken before, during and after pregnancy

Nutrition and pregnancy refers to the nutrient intake, and dietary planning that is undertaken before, during and after pregnancy. Nutrition of the fetus begins at conception. For this reason, the nutrition of the mother is important from before conception as well as throughout pregnancy and breastfeeding. An ever-increasing number of studies have shown that the nutrition of the mother will have an effect on the child, up to and including the risk for cancer, cardiovascular disease, hypertension and diabetes throughout life.

Respiratory tract infections (RTIs) are infectious diseases involving the respiratory tract. An infection of this type usually is further classified as an upper respiratory tract infection or a lower respiratory tract infection. Lower respiratory infections, such as pneumonia, tend to be far more severe than upper respiratory infections, such as the common cold.

Immunization during pregnancy is the administration of a vaccine to a pregnant individual. This may be done either to protect the individual from disease or to induce an antibody response, such that the antibodies cross the placenta and provide passive immunity to the infant after birth. In many countries, including the US, Canada, UK, Australia and New Zealand, vaccination against influenza, COVID-19 and whooping cough is routinely offered during pregnancy.

<span class="mw-page-title-main">High-risk pregnancy</span> Medical condition

A high-risk pregnancy is a pregnancy where the mother or the fetus has an increased risk of adverse outcomes compared to uncomplicated pregnancies. No concrete guidelines currently exist for distinguishing “high-risk” pregnancies from “low-risk” pregnancies; however, there are certain studied conditions that have been shown to put the mother or fetus at a higher risk of poor outcomes. These conditions can be classified into three main categories: health problems in the mother that occur before she becomes pregnant, health problems in the mother that occur during pregnancy, and certain health conditions with the fetus.

A pre-existing disease in pregnancy is a disease that is not directly caused by the pregnancy, in contrast to various complications of pregnancy, but which may become worse or be a potential risk to the pregnancy. A major component of this risk can result from necessary use of drugs in pregnancy to manage the disease.

<span class="mw-page-title-main">COVID-19</span> Contagious disease caused by SARS-CoV-2

Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the virus SARS-CoV-2. The first known case was identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic.

<span class="mw-page-title-main">Gendered impact of the COVID-19 pandemic</span> Aspect of viral outbreak

COVID-19 affects men and women differently both in terms of the outcome of infection and the effect of the disease upon society. The mortality due to COVID-19 is higher in men. Slightly more men than women contract COVID with a ratio of 10:9.

The treatment and management of COVID-19 combines both supportive care, which includes treatment to relieve symptoms, fluid therapy, oxygen support as needed, and a growing list of approved medications. Highly effective vaccines have reduced mortality related to SARS-CoV-2; however, for those awaiting vaccination, as well as for the estimated millions of immunocompromised persons who are unlikely to respond robustly to vaccination, treatment remains important. Some people may experience persistent symptoms or disability after recovery from the infection, known as long COVID, but there is still limited information on the best management and rehabilitation for this condition.

Long COVID or long-haul COVID is a group of health problems persisting or developing after an initial period of COVID-19 infection. Symptoms can last weeks, months or years and are often debilitating. The World Health Organization defines long COVID as starting three months after the initial COVID-19 infection, but other agencies define it as starting at four weeks after the initial infection.
