Excess mortality and COVID-19 deaths in 67 countries: Researchers from the University of Bologna (in Italy) analyzed the gaps between excess deaths and COVID-19 deaths in 67 countries, revealing the capacity of different national health systems to accurately identify COVID-19 cases. Their work was published this week in JAMA Network Open. (For more on excess deaths, see this CDD post about Peru.)
Characterizing long COVID in an international cohort: In another new paper, published this week in The Lancet, COVID-19 long-haulers from the Patient-Led Research Collaborative share the results of an international survey on long COVID-19. The findings indicate that the vast majority of long-haulers (over 90% of those surveyed) suffer from symptoms for at least 35 weeks.
