Mortality Rate Patterns for Hemorrhagic Fever with Renal Syndrome Caused by Puumala Virus
Figure 1. Incidence of acute nephropathia epidemica (NE) and case-fatality rates, Sweden, 1997–2007. A) Age distribution for male and female patients with acute NE. B) Age distribution of case-fatality rates for all patients with acute NE. The Swedish Death Register was used to identify all deceased persons with a diagnosis of NE. Numbers of deaths during different periods after diagnoses were 21 (13 male patients and 8 female patients) during the acute phase (<3 months after diagnoses), 7 (5 male patients and 2 female patients) after the acute phase (>3 months after diagnoses) but <1 year later, and 24 (19 male patients and 5 female patients) during the second year after diagnoses.
