After COVID-19, other infections were more common over the next year
Adjusted risk ratios from a US Veterans Affairs cohort study. Outcomes were counted from 30 days after the COVID-19 test through one year. Values above 1 mean the outcome was more common after COVID-19 than after a negative COVID test. The hospitalized COVID-19 row shows much larger increases.
When both illnesses led to hospitalization, COVID-19 was followed by more later infections than flu
Adjusted risk ratios from a US Veterans Affairs cohort study. The flu hospitalization group is the reference and is set to 1.0. Values above 1 mean the outcome was more common after COVID-19 hospitalization. Outcomes were counted from day 30 through one year.
Relative risk of serious follow-up infections after COVID-19
Comparison of three groups. Test-negative is the reference group at 100%. Values above 100% mean: the risk was higher after COVID-19. Example: 346% = 3.46 times as high as in the test-negative group.
