The first sign of a new bird flu might be a dead seabird or marine mammal. Better surveillance of migratory birds and wildlife – and better public awareness – is crucial.
Improving genomic surveillance to better understand new variants as they arise in different parts of the world could prevent threats to vulnerable health systems and populations.
A nationwide genomic surveillance system analyzes positive COVID-19 tests to build a picture of which variants are spreading in the population.
DNA sequencing has allowed researchers to catch new COVID-19 variants hours after receiving the first positive test sample.
A lot has happened since the WHO declared the coronavirus outbreak a pandemic. A portrait in data highlights trends in everything from case counts, to research publications, to variant spread.
By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.
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.
Genomic sequencing of positive COVID-19 samples could help New Zealand pinpoint the source of its new community outbreak. But it only works if all samples are sequenced – and right now, they’re not.
