The study finds that, at six months follow-up, the health outcomes of people with more than one infection are worse than those with one or no infection.  

The press release discusses potential long-term effects on persistent covid that are not the result of their analysis. As the authors reveal, the cohort of veterans has a selection bias (towards white men) and the possibility of baseline differences between once and multiply infected individuals cannot be ruled out, especially as covid-19 diagnosis may be under-represented in some social groups.
