Summary
What is already known about this topic?
Information about COVID-19 among young adults is limited.
What is added by this report?
Among a convenience sample of 382 young adult U.S. service members aboard an aircraft carrier experiencing a COVID-19 outbreak,
60% had reactive antibodies, and 59% of those also had neutralizing antibodies at the time of specimen collection. One fifth of infected participants reported
no symptoms. Preventive measures, such as using
face coverings and observing social distancing, reduced risk for infection.
What are the implications for public health practice?
Young, healthy adults with COVID-19 might have mild or no symptoms; therefore, symptom-based surveillance might not detect all infections.
Use of face coverings and other preventive measures could mitigate transmission. The presence of neutralizing antibodies among the majority is a promising indicator of at least short-term immunity.
