About

The goal of this project is to understand the household level transmission dynamics and factors that predict transmission of SARS-COV-2 between pediatric and adults in the household. The novel coronavirus SARS-CoV-2 has spread all around the world and testing has posed a challenge globally. Not much is known about who does and does not acquire SARS-CoV2. It is also unknown who will show symptoms or progress severe disease or death from COVID-19. Children tend to have milder symptoms or none at all. Therefore, few children have ever been tested, so it is unknown if they get the infection as much as anyone else. Health care providers are highly exposed, and they do not get tested unless they show severe symptoms. If groups like children and health workers are infected, they can unknowingly spread SARS-CoV-2, unless they practice behaviors like self-isolation very strictly. The investigators aim to measure the prevalence of SARS-CoV-2 in children and health care workers at a large urban health center. The investigators will also measure how many people in the household of the positive children and health care workers also get SARS-CoV-2 infection. Lastly, the investigators will see what other risk factors affect who acquires SARSCoV-2 from inside or outside of the household clusters.

Full description

The rapid spread of the novel coronavirus SARS-CoV-2 has resulted in pandemic levels and a global challenge in diagnosing infection. Little is known about transmission and disease presentation of COVID-19. Children tend to present with mild or no symptoms, and only a minority seem to progress to severe disease. Therefore, fewer have been tested. Health care providers who are highly exposed are under tested for their level of exposure. Under diagnoses in these groups can result in onward transmission of SARS-CoV-2 if non-pharmaceutical interventions like self-isolation are not strictly practiced. The investigators aim to assess the prevalence of SARS-CoV-2 in a pediatric, health care worker and other individuals sample in a large urban health center; Estimate the household secondary attack rate of SARS-COV-2 from the pediatric and adult index case SARS-COV-2 identified through the prevalence survey; and identify risk factors that affect transmission from within and outside of the household clusters. This is an observational prospective cohort study of pediatric patients, New York Presbyterian (and affiliates) health workers, and any individuals who have been exposed to SARS-CoV-2 cases and their household contacts residing in New York City. Child index and their household members who consent to participate will be enrolled and tested for SARS-CoV-2. Households will be followed prospectively for a minimum of 15 days from the date the last household member testing positive. Daily clinical symptom reporting, social distancing behaviors within and outside of the household, emotional and mental health factors such anxiety, stigma and disclosure (among SARS-CoV-2 diagnosed) will be reported by adult household members and minors over the age of 7. Adults will report signs and symptoms for minors under the age of 7. SARS-CoV-2 negative household members will be re-tested around the day of onset of symptoms and baseline negative household members will be tested at the end of the observation period. A proportion of SARS-CoV-2 positive household members will be sampled serially for viral shedding and would be sampled on the day of onset of exposure. Households where all members are positive at baseline visit will be excluded from participation.

Trial design

374 participants in 2 patient groups

Index Case
Description:
a) minor testing positive for SARS-CoV-2; b) symptomatic health workers or any individual with a history of exposure to SARS-CoV-2 confirmed positive patients; c) health workers or any individual who tests positive regardless of symptoms. Index case must be living in a multi-person household that includes at least one child with a history of exposure to SARS-CoV-2 positive patients
Household Contact
Description:
Anyone residing in the house for at least 24 hours at the time of the index case diagnosis or study enrollment.
