60% of people infected by SARS-CoV-2 on the Theodore Roosevelt displayed no symptoms
After one crew member tested positive for COVID-19 on a United States aircraft carrier, 94% of the 4,800 crew members were tested. More than 600 tested positive, yet the majority experienced no symptoms.
In total, 60% of those aboard the Theodore Roosevelt who tested positive for SARS-CoV-2 reported no symptoms.
It is worth noting that the individuals aboard this ship were all young adults and, therefore, not indicative of the U.S. population; also, some of the 60% may go on to develop symptoms. However, 60% is significantly higher than other estimates, which range from 25–50%.
