Where coronavirus variants emerge, surges follow – new research suggests how genomic surveillance can be an early warning system

By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.

Genomic surveillance: What it is and why we need more of it to track coronavirus variants and help end the COVID-19 pandemic

The US lags in testing coronavirus samples from COVID-19 patients, which can help track the spread of the virus and the emergence of new variants. But labs are ramping up this crucial surveillance.

The scene from Cuba: How it’s getting so much right on COVID-19

Cuba's access to internationally produced vaccines was nearly impossible due to the U.S. blockade. Its decision to make its own vaccines stands to pay off handsomely.

South Africa’s immunisation record risks being dented by anti-vaccination views

Vaccine hesitancy has resulted in multiple vaccine-preventable disease outbreaks. Research on vaccine hesitancy in South Africa is limited. But growing evidence suggests that it's becoming a problem.
