Correction to: Nature Immunology https://doi.org/10.1038/s41590-020-0648-y, published online 20 April 2020.

In the version of this article initially published, in Table 2, “virus” was used rather than “pathogen” in the row “International travel and trade,” under the heading “Globalization and environment,” and in the row “Research,” under the heading “Public health systems.” The error has been corrected in the HTML and PDF versions of the article.
