Understanding Covid-19 and pregnancy

The World Health Organization’s new guidelines state:

‘There is no evidence that pregnant women present with different signs or symptoms or are at higher risk of severe illness. So far, there is no evidence on mother-to-child transmission when infection manifests in the third trimester …  WHO recommends that caesarean section should ideally be undertaken only when medically justified.’

Why pregnant women are not more susceptible to Covid-19

Pregnant women are generally more susceptible to viruses that cause breathing problems (like the flu). Their immunity is lowered, their lungs are more compressed and they need more oxygen.

However, this doesn’t seem to be the case with Covid-19. In an analysis of 147 women with Covid-19, only 8% had severe disease and 1% were in critical condition. That’s lower than the general population. The lowered immune response of pregnancy, which is needed to stop a woman’s body responding to her baby as a health threat, may actually provide extra protection with Covid-19.

Covid-19seems to be more severe in people with an immune system working hard dealing with other health disorders. With Covid-19, more men than women are affected and women are less likely to get severely ill and die. To date, the death rate is 1.7% for women and 2.8% for men.

However, as the pandemic spreads this may change. Women comprise the majority of the health workforce and caregivers will be in contact with more sick people.

How can pregnant women protect themselves and others?

Pregnant women should do the same things as the general public to protect themselves, including:

• Covering the mouth when coughing (by coughing into the crook of your elbow)
• Avoiding people who are sick
• Asking people who are unwell to avoid visiting
• Washing hands often with soap and water or an alcohol-based sanitiser
• Avoiding large gatherings

It would be sensible not to travel overseas at the moment; you may have to self-isolate when you return.

If you have been asked to self-isolate due to contact with someone with Covid-19, or have the illness yourself, make sure you contact your midwife or obstetrician by phone and follow the advice of your health care provider.

What about going to hospital for antenatal visits and birth?

Keep going to appointments but don’t stress if you miss a couple, and an early discharge from hospital might be a good idea if you’re able. If you are booked into a birth centre or hospital, lots of precautions are in place to minimise the risk of infection. Birth will proceed as planned in the vast majority of cases, and going home early would be ideal – and may even be encouraged if you and your baby are well. Be aware that some hospitals are restricting visitors and even support people, other than patients’ partners, to try and reduce risk to the community.

Can a baby be infected with Covid-19in the uterus?

The placenta is a very efficient filtering system and does an amazing job protecting babies from harm. (The Zika virus was an exception to this.) There is no evidence of increased complications, though if a woman is very unwell (with high temperature or pneumonia, for instance) then the baby may be born prematurely. This may be due to deliberate intervention by health professionals if the woman is very sick. In general, though, a Covid-19diagnosis should not lead to a decision for an early birth, unless ending the pregnancy is thought to be beneficial to the mother due to her overall condition.

There is not enough evidence that Covid-19increases miscarriage and it is too early to know other longer-term impacts on the baby.

What should I do after the birth?

The benefits of breastfeeding are so significant that the World Health Organization  recommends this should begin within an hour of birth. Skin-to-skin contact should be supported immediately following birth if the baby is well.  If the mother is too ill, she should be assisted to express her milk. Breastfeeding is particularly effective against infectious diseases because it transfers antibodies and other important immune factors to the baby. If the woman or the baby have an infection, the composition of breast milk even changes to increase important components that help the baby fight infection. So, if you were thinking of giving up breastfeeding, perhaps continue until this pandemic ends.

The World Health Organization recommends women who have Covid-19should wash their hands before and after contact with the baby, use a medical mask when near the baby if they have symptoms (such as coughing), and routinely clean and disinfect surfaces they may have touched.

What else can you do?

When the seasonal flu vaccine becomes available, get vaccinated. We know this can be protective during pregnancy. It is free for pregnant women and there are no risks to your baby from the flu vaccine. You will not be protected from Covid-19, but you will get some protection from the flu (which can be very problematic for pregnant women). The last thing you want is to have the flu and Covid-19at the same time.

Most of all, try and stay calm, and talk to your midwife or doctor if you are getting very worried.
