Only six US states have genetically sequenced more than 1% of their total coronavirus cases during the pandemic, compared to a national average just over 0.3%, according to data posted this week by the US Centers for Disease Control and Prevention.

These states include Hawaii (2.8%), Washington (2.1%), Maine (1.7%), Wyoming (1.6%), Utah (1.5%) and Oregon (1.2%).

Meanwhile, nearly half of states have sequenced less than one tenth of one percent of their confirmed cases – 24 in total.

These are the states who preformed the highest raw number of genetic sequences:

  • Texas: More than 15,000
  • California: More than 11,000
  • New York: About 7,600

Fourteen states report fewer than 100 sequences each.

These numbers come from sequences in a publicly accessible database from January 2020 to January 2021 and may not represent the full number of samples that have been analyzed.

US labs have submitted 92,000 sequences of the coronavirus – around 0.3% of total cases – to a genomics database known as GISAID. In comparison, the UK has submitted nearly 197,000 – just over 5% of its total cases.

The US has been ramping up its sequencing efforts and is on track to process at least 7,000 samples per week, according to CDC Director Dr. Rochelle Walensky.

Experts have previously told CNN that the US should aim to sequence 5% to 10% of cases, in line with sequencing efforts in the UK. Given cases over the past seven days, this would amount to roughly 50,000 to 100,000 sequences in a week.
