How COVID-19 and other common respiratory viruses affect young children

Official title: SARS-CoV-2 and Respiratory Virus Co-Infections Among Young Children

Funded at Kaiser Foundation Research Institute · NIH-11401570 · Data updated 2026-11-12

Looks at how having COVID-19 at the same time as other respiratory viruses changes illness and complications in infants and young children.

Who could benefit from this research

Could help

Infants and young children, especially those aged 0–2 years, with recent respiratory symptoms, a positive COVID-19 test, or hospitalization for respiratory illness.

Less likely to help

Adults and children without respiratory infections or whose conditions are unrelated to viral co-infections are unlikely to benefit directly from this work.

What this research studies

If your child joins, researchers will compare children who have COVID-19 alone with those who also test positive for viruses like RSV, influenza, or rhinovirus. They will collect medical records, symptom information, and respiratory samples from children seen in clinics and hospitals and run lab tests to identify which viruses are present. The team will follow how sick children become, note complications such as respiratory failure or MIS-C, and measure markers of inflammation to see how co-infections affect outcomes. Findings are intended to show which young children are at higher risk and to inform better treatment and prevention strategies.

Why it matters

Potential benefit: Could help doctors identify high-risk children and guide treatments or prevention to reduce severe respiratory illness.

How similar studies have gone: Prior studies indicate co-infections can worsen illness in very young children, but comprehensive prospective studies combining clinical data and lab testing remain limited.
