Can You Get Covid-19 Again? It’s Very Unlikely, Experts Say
Reports of reinfection instead may be cases of drawn-out illness. A decline in antibodies is normal after a few weeks, and people are protected from the coronavirus in other ways.

"People infected with the coronavirus typically
produce immune molecules called antibodies. Several teams have recently reported that the levels of these antibodies decline in
two to
three months, causing some consternation. But a drop in antibodies is perfectly normal after an acute infection subsides, said Dr. Michael Mina, an immunologist at Harvard University.
Many clinicians are “scratching their heads saying, ‘What an extraordinarily odd virus that it’s not leading to robust immunity,’ but they’re totally wrong,’” Dr. Mina said. “It doesn’t get more textbook than this.”
Antibodies are not the only form of protection against pathogens. The coronavirus also provokes a
vigorous defense from
immune cells that
can kill the virus and quickly rouse reinforcements for future battles. Less is known about how long these so-called memory T cells persist — those that recognize other coronaviruses may linger for life — but they can buttress defenses against the new coronavirus.
“If those are maintained, and especially if they’re maintained within the lung and the respiratory tract, then I think they can do a pretty good job of stopping an infection from spreading,” said Akiko Iwasaki, an immunologist at Yale University."
