There is still so much to learn about the novel coronavirus, but scientists have unlocked some clues about the way COVID-19 affects pregnant women and their unborn children.

A review of dozens of scientific studies has found that women who contract coronavirus during pregnancy may have a higher risk of premature delivery.

Also on the show:

* Everyone has an opinion about mandatory isolation for positive cases!

* Can you tell if you've got COVID-19 by monitoring your resting heart rate?

* What percentage of people would need to be vaccinated to lift restrictions?
