Sweeping testing of the entire crew of the USS Theodore Roosevelt may have revealed an important clue about the pandemic: A majority of the sailors who tested positive for COVID-19 showed no symptoms.

The Navy found that out of the 4,800 member crew - about 600 were positive for the virus. 60 percent of those were asymptotic.

The figure is higher than the 25% to 50% range offered by Dr. Anthony Fauci, the top U.S. infectious disease expert on President Donald Trump's coronavirus task force.

Although no ages of the infected crew were available, it is likely that many of them were young people.
