I don't believe there's any studies on that. The virus was only discovered at the beginning of December.

Most likely they are referencing this study showing 40% of people who had SARS had long lasting effects https://jamanetwork.com/journals/jamainternalmedicine/fullar...

While COVID-19 mutated from SARS it has a number of characteristics that are different so I don't think it's reasonably to assume it'd be the same. Could be worst or better.
