“For patients who do not display the classic COVID-19 symptoms, which usually involve a combination of respiratory problems and a fever, the common nasal swab test is also problematic, according to Patel. “As the virus migrates … into other parts of your body, you might not have a nasal swab that’s always positive, which is why it’s not a perfect test itself,” she said.
The worst-case scenario, both for the Theodore Roosevelt and for society at large, would be if the individuals who tested positive after recovering from COVID-19 had actually been reinfected, because that would not only mean they are capable of infecting others, but it would also imply that recovery from the disease confers little to no immunity against reinfection. In the case of the sailors on the carrier, that possibility is “less likely” because of how soon after testing negative the crew members reported symptoms, Omer said. “The time period is fairly short for it to be the more plausible scenario.”
Patel also sounded an optimistic note about the other reports of COVID-19 survivors who have retested positive. “I haven’t seen global evidence of reinfection,” she said. It might be a plausible explanation in some cases, she added, “but given how infectious this virus is, I would expect there to be more.”
