*Study participants were adults who had received a diagnosis of serologically and clinically confirmed hantavirus infection during 2001–2012 and who later (7–35 mo) participated in a follow-up study. –, not applicable.
†Hypertension stages 1 and 2 were defined according to the classification of blood pressure for adults (26).
‡Includes only those participants who had hypertension at the first follow-up visit. Retesting was done within 8 wk after first follow-up visit.
