Back in January, Bara Vaida, the AHCJ core topic leader for infectious disease, wrote a helpful post on resources for tracking COVID-19 variants. But in the age of COVID, data moves fast enough to give us constant whiplashes, and so much has changed since then. The most significant change is that the number of variants of concern — a term that not yet defined at the time of Vaida’s post — has grown to at least five:
- 1.1.7 (UK)
- 1.351 (South Africa)
- 1 (Brazil)
- 1.427 and B.1.429 (California)
Scientists have also learned a lot more about the individual mutations in each variant, such as what advantage they might give the virus and how these can overlap across variants.
Below is a list of resources that can be helpful for reporting on variants, particularly if you’re trying to go in-depth into the science of mutations. In addition to Vaida’s list of sources, I’ve added my own recommendations for interviews on variants, as well as a Twitter list I’ve created to track those following the nitty-gritty details of them. Some of the resources below duplicate those in Vaida’s list, but I recommend reading her blog post first for its excellent background info.
- CDC SARS-CoV-2 Variant Classifications and Definitions
- CDC US COVID-19 Cases Caused by Variants
- Nextstrain Real-time tracking of pathogen evolution (which tracks many other viruses besides SARS-CoV-2)
- This CoVariants website, developed by a group of scientists (any of whom would be good sources) at the University of Bern in Switzerland, includes a list of all variants and offers soome excellent, colorful, helpful distribution graphs and models of where the mutations are in the virus. The site also features an awesome, colorful matrix of shared mutations across the different variants. (Seriously, this site is gorgeous and a public health/immunology/infectious disease/virology nerd’s dream. It even has a graph of the prevalence of each variant for every single country.)
- Outbreak.info has a detailed lineage tracker.
- The New York Times Tracker of Coronavirus Variants and Mutations is absolutely fantastic, with incredible graphics and multimedia about the major variants and mutations as well as excellent explanations of what you’re viewing.
- Twitter list of folks to follow for discussions of SARS-CoV-2 mutations and variants
