简要总结

This study is a interventional study that present minimal risks and constraints to evaluate the presence of novel coronavirus (SARS-CoV-2) or antibodies among individuals living in households where there is a confirmed coronavirus case in order to provide useful information on the proportion of symptomatic forms and the extent of the virus transmission in tropical regions such as French Guiana, Guadeloupe and New-Caledonia.

详细描述

This study is a interventional study that present minimal risks and constraints to evaluate the presence of novel coronavirus (SARS-CoV-2) or antibodies among individuals living in households where there is a confirmed coronavirus case in order to provide useful information on the proportion of symptomatic forms and the extent of the virus transmission in tropical regions such as French Guiana, Guadeloupe and New-Caledonia.

Subjects will be assessed (questionnaires and sampling) in their homes. Subjects will be asked to attend study visits at days 0, 7, 14, 21, 28, 60, 90, 180 and 360.

The primary objective of the study is to evaluate the rate of intra-household secondary transmission of the virus.
