The human disease caused by SARS-CoV-2 is called COVID-19. In most cases, COVID-19 presents as a mild to moderate respiratory illness. But it can also be more severe and even lead to death.
The purpose of this study is to:
- Determine the prevalence of SARS-CoV-2 carrier status over time in children and parents
- Determine the prevalence of antibody development over time in children and parents
- Compare carrier status and antibody development for children with asthma and/or other atopic conditions (e.g. eczema) versus children without asthma and/or other atopic conditions
- Investigate the presence of SARS-CoV-2 exposure in historical samples from enrolled participants

| Coronavirus Disease 2019 (COVID-19) SARS-CoV-2 | Procedure: Collection of Biological Samples Procedure: Symptom and Exposure Surveys |
The study population will include children that are participants in NIH-funded cohort studies and their families (household contacts).The intent is to recruit families that have experience with the collection of respiratory samples.
The objective of this surveillance study is to identify the rate of infection in children and what, if any effect, atopy has on the SARS-CoV-2 carrier status.
The initial surveillance interval for participants will be 6 months and, depending upon the findings, may be extended. During surveillance, biological samples will be collected by the family at established intervals and symptom and exposure surveys will be completed remotely via a smart phone, on-line, or phone communications at the time the biological samples are collected.

SARS-CoV-2 Surveillance: Total Group
Participants either currently or in the past, enrolled in National Institutes of Health (NIH)-funded cohort studies, and their families (household contacts). Active surveillance for detection of SARS-CoV-2 for 6 months, beginning with enrollment. During surveillance, biological samples will be collected by the family at established intervals and symptom and exposure surveys will be completed at the time that biological samples are collected. |
Procedure: Collection of Biological Samples
Biological samples will be collected throughout the study at regular intervals (every 2 weeks) in addition to when illness event(s) occur. All biological samples (e.g. nasal swabs, peripheral blood, stool) will be collected by the caregiver at home using materials provided to the family. At the end of study, additional samples (e.g. nasal secretion and/or saliva samples) may be collected by the family or study staff at a site visit, if feasible. Procedure: Symptom and Exposure Surveys Symptom and exposure surveys (questionnaires) will be completed throughout the study at regular intervals (every 2 weeks) in addition to when illness event(s) occur. The primary household contact/caregiver will be the designee for ensuring timely questionnaires completion and submission for all household study participants.

- Cumulative Incidence of SARS-CoV-2 RNA Detection in Nasal Samples Among Index Participants and Their Household Contacts Over the Study/Surveillance Period [ Time Frame: Up to Week 24 ]
Included: Participants currently or in the past enrolled in NIH-funded studies who fulfill inclusion criteria (index participant) and their family/household contacts.
Calculated at the end of surveillance/study follow-up or fate, defined as follows:
-
Time from entry until the first of the following events:
- Tests positive for SARS-CoV-2 RNA in nasal samples
- Is lost to follow-up or withdraws from the study
- End of study (Week 24)
-
Fate at the end of follow-up:
- 1 (positive): If the participant tests positive for SARS-CoV-2
- 0 (censored): If the participant has no evidence of having had disease by the end of follow-up
-
