'We were in the dark': why the US is far behind in tracking Covid-19 variants
As researchers around the world scramble to understand the dangers of several newly discovered variants of the deadly coronavirus, the US remains woefully behind in its ability to track the mutations, scientists say.
The federal government has had its “head in the sand”, failing to develop a coordinated surveillance system for tracking the genetic footprints of the virus, according to academic researchers, scientific panelists and private entrepreneurs, who say they have been urging US officials for months to make better use of the hi-tech resources already sitting in labs around the country.
Genomic sequencing looks at the entire genetic code – or genome – of viruses obtained from samples from infected patients. The technique allows researchers to watch for dangerous mutations and to track movements of specific variants, like detectives following footprints.
Most genetic variations are inconsequential. But to discover those with functional differences, like more transmissible variants first identified in the UK (B117) and in South Africa (B1351), developed by scientists at the . Some US states have had virtually no surveillance at all.
