An epidemiologic investigation that began on January 1, 2020, identified a population of 1,000 people among whom four were found to have congestive heart failure on this date. During the year of the study, six additional new cases were found. Among the 10 cases, there were seven deaths during the year. There were no deaths among the remaining 990 people.
