Top epidemiologist Marc Lipsitch on whether we’re winning or losing against COVID-19

…I think it remains to be seen whether we in the United States can do better than just letting everybody get it gradually … If it’s about 5 or 10% of the population now, I can’t envision a scenario where we have a vaccine or a really good treatment before it’s about twice that. … Clearly we need a lot of creative thinking about alternative ways to make life go on.

In March Professor Marc Lipsitch — director of Harvard’s Center for Communicable Disease Dynamics — abruptly found himself a global celebrity, his social media following growing 40-fold and journalists knocking down his door, as everyone turned to him for information they could trust.

Here he lays out where the fight against COVID-19 stands today, why he’s open to deliberately giving people COVID-19 to speed up vaccine development, and how we could do better next time.

As Marc tells us, island nations like Taiwan and New Zealand are successfully suppressing SARS-COV-2. But everyone else is struggling.

Even Singapore, with plenty of warning and one of the best test and trace systems in the world, lost control of the virus in mid-April after successfully holding back the tide for 2 months.

This doesn’t bode well for how the US or Europe will cope as they ease their lockdowns. It also suggests it would have been exceedingly hard for China to stop the virus before it spread overseas.

But sadly, there’s no easy way out.

The original estimates of COVID-19’s infection fatality rate, of 0.5-1%, have turned out to be basically right. And the latest serology surveys indicate only 5-10% of people in countries like the US, UK and Spain have been infected so far, leaving us far short of herd immunity. To get there, even these worst affected countries would need to endure something like ten times the number of deaths they have so far.
