Larry Brilliant on how well we are fighting Covid-19
WIRED interviews epidemiologist, Larry Brilliant:
WIRED: We talked 100 days ago. What is different about the pandemic now?
Larry Brilliant: A hundred days ago we didn’t really understand the pathophysiology—the way the virus and the human body interact, the illness as opposed to the epidemic. The unexpected things that it’s doing are not epidemiological—they are virological. In March, we were just beginning to see these horrific CT scans or x-rays of people with ARDS, acute respiratory distress syndrome, where they had these big circles of holes in their lungs, and we were thinking this is pretty much a respiratory disease. Since then we have learned that this virus attacks almost every organ in the body. The joke is that it’s from nose to toes, because you lose your sense of smell and you can get “Covid toes,” the swelling of your toes and your fingers that look like frostbite. There is still a lack of clarity on how it chooses entry points in the cells.
It seems like the longer it goes, the less we know about it. Every week something new comes up that contradicts what we thought we already knew.
No, no—you know a lot more about it now than you did three months ago. Yes, there are absolutely more questions today than there were 100 days ago. But part of that is because we’re getting more sophisticated in our ability to ask questions. Three months ago, we had only had a couple hundred cases of this novel virus. We have now got over 11 million cases, and a half a million deaths globally. The virus has been speeding along at an exponential speed, but so has science. So now we can begin to understand that this virus attacks the circulatory system, it attacks the vascular and nervous systems, it attacks the respiratory system, it attacks our ability to bring in oxygen. That’s why people can go to the hospital and be on their phone, not in any respiratory distress, but have oxygen saturation in the 50s, which in the old days we’d think of as you’re near death. It also makes you understand why you can get these Covid toes, why you can lose your sense of taste or smell, why you can have a stroke. This virus attacks blood vessels, it creates blood clots. That is probably one of the reasons why it causes strokes. We have a very large number of deaths due to kidney failure, and we are having terrible results from the ventilators that we were so obsessed about early on, though lately it’s looking a little better, because we’ve learned more about how to use them for this disease. We have learned a tremendous amount about this virus, about how it infects people, how it kills, how it spreads, but the big surprise to me is the kind of pan-organ nature of its attack. It gives the lie to anybody who thought that a comparison with influenza was in the ballpark. [Continue reading…]
