Estimated hospitalization fatality risks for laboratory-confirmed Influenza A(H7N9) cases, 10 April to 31 May, 2013. (A) HFR1 based on the number of deaths divided by the number of confirmed cases. (B) HFR2 based on the number of deaths divided by the number of confirmed cases with known outcome (death or discharge). HealthMap, Virginia Tech and HKUSPH did not routinely collect data on the number of discharged patients. The most updated estimate of the HFR [19] is shown by the gray lines. Vertical lines indicate the 95% confidence intervals. Date of analysis refers to US local time for HealthMap, Virginia Tech and FluTrackers line lists, and China local time for China CDC, Bloomberg and HKUSPH line lists. China CDC, Chinese Center for Disease Control and Prevention; HFR, hospitalization fatality risk; HKUSPH, the University of Hong Kong School of Public Health.
