Why does it seem like recommendations around Covid-19 are changing all the time? Elizabeth Tracey reports


Wear a mask, don’t wear a mask. Avoid crowded places, dine outside. Go ahead and dine inside…it seems like recommendations are a moving target, so what should you do? Lisa Maragakis, an infectious disease expert at Johns Hopkins, feels your pain.

Maragakis: One factor is that we are learning all together about this new virus. No one had ever seen it before. Now we’re two years in, so we’ve learned a lot, but you have seen things change, recommendations change, over time because information changed and we learned more about the virus and then even the virus has changed. And we’ve seen different versions of it coming and going. There are other factors in the complex world of trying to take that scientific information and then make public policy from it.  :34

Maragakis predicts continued changes as more evidence accumulates, and urges flexibility. At Johns Hopkins, I’m Elizabeth Tracey.
