Estimating the Proportion of Coronavirus Disease 2019 Contacts Among Households based on Individuals with Myocardial Infarction History: a cross-sectional telephone survey
ABSTRACT
Background:
Adults with cardiovascular diseases were disproportionately associated with a significantly increased risk of a severe form of COVID-19 and all-cause mortality.
Objective:
We aimed to report the associated symptoms for COVID-19 cases, and to estimate the proportion of contacts.
Methods:
We conducted a two-week cross-sectional telephone survey during the first lock-down period in France, including all households with at least one individual with pre-existing cardiovascular disease in the past two years.
Results:
We observed high rates of compliance with health measures, regardless of age or risk factors. Four COVID-19 cases were reported from four different households. We estimated that 9.73% were contacts of whom 71.52% were asymptomatic. Among individuals with myocardial infarction history, two were COVID-19 cases. We estimated that 8.68% were contacts of whom 68.85% were asymptomatic. The cases and contacts presented different symptoms, with more respiratory signs.
Conclusions:
The telephone survey could be a relevant tool for reporting the number of contacts on a limited period and area, based on the presence of associated symptoms and COVID-19 cases in the households. This study advanced our knowledge to better prepare for future crises.
