What is a coronavirus? Coronaviruses belong to a family known as “Coronaviridae,” and . They’re named for these spikes, which form a halo or “crown” (corona is Latin for crown) around the viral body.  Coronaviruses contain a single strand of RNA (as opposed to DNA, which is double-stranded) within their viral body (or “viral envelope”). As a virus, they can’t reproduce without getting inside living cells and hijacking the machinery within. The spikes on the viral envelope help coronaviruses bind to cells, and then get inside them as if jimmying their way through a locked door. Once inside, they turn the cell into a virus factory — the RNA and a handful of enzymes use the cell’s machinery to produce more viruses, which are then shipped out of the cell and infect other cells. Thus, the cycle starts anew.
