- Although case numbers in the youngest age group are small, infants are still at risk for developing 2019-novel coronavirus (COVID-19) disease.
- 100% of cases have been linked to family clustering.
Why this matters
- Special protective measures are important, but face masks are not recommended for infants.
- Infants with infected family members should be monitored and evaluated, these authors say.
- Experts advise that adult caretakers should wear masks, wash hands before and after close contact with infants, and sterilize all toys/tableware on a regular basis.
- 9 hospitalized infants (ages, 1-11 months; 7 females).
- Clinical features: 4 had fever, 2 mild upper respiratory tract symptoms, 1 no symptoms (but tested COVID-19-positive because of exposure to infected family members), 2 with no information.
- Time between admission and diagnosis: 1-3 days.
- 9/9 infants had at least 1 infected family member; all infections occurred postexposure.
- 7/9 infants were living in Wuhan or had family member who had traveled there, 1 had no direct Wuhan linkage, and 1 no information.
- None required intensive care or mechanical ventilation or had severe complications.
- Retrospective case analysis of demographic, epidemiological, clinical features in Chinese infants hospitalized with COVID-19 from December 8, 2019 to February 6, 2020.
- Funding: National Natural Science Foundation.
- Small sample size.
- Limited to hospitalized, symptomatic infants.
- Underreporting likely.
