Background
Household studies are crucial for understanding the transmission of
SARS-CoV-2 infection, which may be underestimated from PCR testing of
respiratory samples alone. We aim to combine assessment of household
mitigation measures; nasopharyngeal, saliva and stool PCR testing; along
with mucosal and systemic SARS-CoV-2 specific antibodies, to
comprehensively characterise SARS-CoV-2 infection and transmission in
households.
