Psssst... pass it on:

COVID LUNG is worse than smoker’s lung.

"Post-COVID lungs look worse than any type of terrible smoker's lung we've ever seen. And they collapse. And they clot off. And the shortness of breath lingers” says Dr @BKendallMD. #COVID19

2) All that white on the X-ray is scarring. You don’t want it. Many have COVID lung even if asymptomatic.

How common is severe chest X-rays?

100% of time if symptomatic

70-80% of time if asymptomatic. #COVID19

3) Many others are highlighting this issue. Look how even longer term #COVID19 survivors’ lungs look compared to healthy. Lots of damage long term, even if not severe illness. https://twitter.com/dianaberrent/status/1349725613670719490

4) look how normal lung tissue compares to people who died of #COVID19

5) Now look how normal heart tissue looks compared to a #COVID19 patient’s heart. Dramatic damage.

6) Now look at the vascular blood vessel damage in special software in *living #COVID19 patients*. The middle patient had seemingly normal CT scan, but clearly shows significant damage.

7) This lung issue is very personal to me too. As a child, due to a tumor, I lost a large section of my right lung that had to be removed along with my baseball sized tumor that invaded my lung. It made me want to study epidemiology at Hopkins. Story: https://well.blogs.nytimes.com/2011/12/08/a-web-campaign-for-cancer-prevention/
