Topic:

  • Among a convenience sample of 382 service members aboard the USS Theodore Roosevelt, 60% had reactive antibodies to SARS-CoV-2, 59% of whom had neutralizing antibodies. In several participants, neutralizing antibodies were still detectable >40 days after symptom onset. Of those with previous or current SARS-CoV-2 infection, 20% were asymptomatic. Service members who reported taking preventive measures, such as wearing face coverings and observing social distancing, had lower risk of infection.
