Covid-19 long-term effects: People with persistent symptoms struggle to get care

At the beginning of the Covid-19 pandemic, “the assumption was that
people would get better, and then it was over,” Peluso says. “But we
know from lots of other viral infections that there is almost always a
subset of people who experience longer-term consequences.” He explains
these can be due to damage to the body during the initial illness, the
result of lingering viral infection, or because of complex immunological
responses that occur after the initial disease.
