Correction to: Nature Reviews Disease Primers https://doi.org/10.1038/s41572-023-00429-2. Published online 6 April 2023.

In the version of this article initially published, there was an error in the fifth sentence of the “Function is nsPs” subsection, where in the text now reading “sgRNA is translated to produce the structural proteins,” “structural proteins” initially read “nsPs” (non-structural proteins). In Figure 2, step 1, the percentage values “7–13%” on the left and “87–93%” on the right were initially reversed. The third sentence of the Figure 2 legend referred to “micropinocytosis” instead of “macropinocytosis”. The errors have been corrected in the HTML and PDF versions of the article.
