Does not have serological evidence of past asymptomatic SARS-CoV-2 infection in medical history or Tier 1 testing, AND 3. Lives in the same communities or recruited from the same sources as those in the SARS-CoV-2 infected cohort, AND 4. Either not hospitalized for any reason in prior 3 months, or hospitalized (with or without ICU stay) within the prior 3 months 5. Uninfected individuals may participate independent of their vaccination status 6. Uninfected individuals who develop SARS-CoV-2 infection during the study period will be reassigned to the SARS-Cov-2 infected group and will be considered to have been enrolled prior to SARS-CoV-2 infection. Children (≤3 years of age) born in and out of the context of maternal SARS-CoV-2 infection during pregnancy. 1. Children ≤3 years of age born to a childbearing parent with history of suspected, probable, or confirmed SARS-COV-2 infection during pregnancy (according the same criteria listed for the infected child cohort) will be enrolled in the study from existing research cohorts at the maternal fetal medicine sites in the RECOVER. network. 2. Children ≤3 years of age born to a childbearing parent without history of SARS-COV-2 infection during pregnancy (according to the same criteria listed for the non-infected child cohort) will also be enrolled from the same existing research cohorts at maternal fetal medicine sites in the RECOVER network. Children with MIS-C Children/young adults with SARS-CoV-2 infection who have history of MIS-C meeting the CDC definition: 1. An individual aged \<21 years presenting with fever\*, laboratory evidence of inflammation\*\*, and evidence of clinically severe illness requiring hospitalization, with multisystem (\>2) organ involvement (cardiac, renal, respiratory, hematologic, gastrointestinal, dermatologic or neurological); AND 2. No alternative plausible diagnoses; AND 3. Positive for current or recent SARS-CoV-2 infection by RT-PCR, serology, or antigen test; or exposure to a suspected or confirmed COVID-19 case within the 4 weeks prior to the onset of symptoms. * Fever \>38.0°C for ≥24 hours, or report of subjective fever lasting ≥24 hours \*\*Including, but not limited to, one or more of the following: an elevated C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), fibrinogen, procalcitonin, d-dimer, ferritin, lactic acid dehydrogenase (LDH), or interleukin 6 (IL-6), elevated neutrophils, reduced lymphocytes and low albumin Young adults with past history of MIS-C with current ages 22-25 years are eligible to participate.

Primary Caregiver Entry Criteria 1. A primary caregiver is defined as an individual, such as a family member (biological or nonbiological) or legal guardian, who is responsible for the care of the enrolled child and resides in the same household as the child. When possible, the primary caregiver identified at study entry will remain in the same role throughout the study. 2. The primary caregiver is the caregiver who spends the most time with the child or young adult, has substantial responsibility for taking care of him/her on a daily basis, and is most knowledgeable about him/her. 3. If two or more persons share equally in the caregiver responsibilities for the child or young adult, the person selected by the family to fill out study forms both about themselves and the child will be considered the primary caregiver. 4. If a biological family member primary caregiver has not reached the legal age of majority in their jurisdiction, the parent/legal guardian for the minor primary caregiver will provide consent for participation, with assent provided by the minor caregiver. 5. A nonbiological primary caregiver or legal guardian serving as primary caregiver must be above the legal age of majority in their jurisdiction. 6. The primary caregiver cannot be a babysitter or other childcare provider who receives money to care for the child. Biological Parent Entry Criteria \- If the primary caregiver is a biological parent of the child or young adult who is participating in the study, the other biological parent may be enrolled to provide a home sample of saliva for DNA analysis. Exclusion Criteria An individual who meets any of the following criteria will be excluded from participation in this study: 1. Any child, young adult, caregiver, or other biological parent who in the opinion of the site investigator may be at increased risk of adverse events during participation in the study, or who may not be able to complete study procedures due to co-morbid disease or disability. 2. Any young adult age above the age of majority who lacks capacity to provide consent 3. Nonviable neonates and neonates of uncertain viability as determined by the treating physician 4. Any child, young, adult, or caregiver with co-morbid illness with expected survival \<2 years 5. Any child who is being given up for adoption or is a ward of the state 6.
