Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Viral respiratory tract infections are very common in children. They contribute to missed time in school, work disruption for caregivers and can also cause severe illness requiring hospitalization and rarely death. In the 2022-2023, influenza, RSV and SARS-CoV-2 viruses infected a large number of children which strained the pediatric healthcare system in many jurisdictions. Unfortunately, there continues to be limited data on duration of infectiousness and transmission risk of these viruses to inform public health decisions during times when there is significant circulation of these viruses.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Viral dynamics (primary outcome):

* Be within 5 days of symptom onset


-Any individual in the same household (i.e. household contacts, defined as residing at the same address) as the individual testing positive by PCR for influenza, RSV, SARS-CoV-2, mycoplasma pneumoniae, or bordetella pertussis


-Any individual in the same classroom (i.e. classroom contacts) as the individual testing positive by PCR for influenza, RSV, SARS-CoV-2, mycoplasma pneumoniae, or bordetella pertussis (i.e. case identified through the THS program)
