A year after discovering the SARS-CoV-2 virus, the pandemic’s end seems just beyond the horizon as more and more hold out hope that a highly effective vaccine may soon be widely available. Returning to a Covid-free reality is a yearning we all share, but there’s reason to believe we may never be Covid-free again because of the genuine possibility that Covid-19 will become an endemic disease; people once infected may become reinfected.
We still know little about Covid-19 reinfection incidence. There have been official cases across continents and undoubtedly many more that have gone unreported. A Lancet report confirmed that in mid-October, the virus reinfected a man in Nevada. His symptoms were more severe during the second infection, but he has since recovered. Whether symptoms are worse on the first or second infection seems to vary from case to case.
