Resource-poor countries (including Bangladesh, Sri Lanka and Suriname) process samples faster than the United States.
Dr. Peter Hotz, a virologist at Baylor College of Medicine, said: “This is very sad.”
Hotes said: “When you wait for 85 days, a sequence can change from a rare variant to half of the virus circulating in the population.”
Gene sequencing is the key to finding new mutations. If too much time passes before the sequence is released, it will make it more difficult for scientists to catch new mutations, warn the world and take appropriate steps to control them.
The UK is one of the fastest countries to release gene sequencing, which takes 24 days.
Dr. Nancy Cox, former director of the influenza division of the US Centers for Disease Control and Prevention, said: “When many countries perform well, I think it should tell us that the United States should be united.
An official from the CDC told CNN that the time lag reported on GISAID is “misleading” but “timeliness will be improved.”
GISAID is “a repository of genomic data generated for a variety of purposes, including genome monitoring (the turnaround time for those samples is usually short) and research projects (the time interval from sample collection to submission is very variable),” Gregory Armstrong Ph.D. Director of the Office of Advanced Molecular Testing at the National Center for Emerging and Zoonotic Infectious Diseases of the Centers for Disease Control and Prevention (CDC), he wrote in an email to CNN.
In the United States, the Centers for Disease Control and Prevention, national health departments, private companies and university laboratories submit sequences to GISAID.
Armstrong added: “All this is not to say that turnaround time is irrelevant,” Armstrong added, “We signed a contract with a large laboratory from late December to early January.
Considering that the virus is rampant in the country. To this extent, the United States is not only criticized, but also accused of being too late for sequencing virus samples.
According to GISAID, the United States has mapped and released samples from nearly 70,000 Covid-19 populations. This is second only to the United Kingdom, which has posted more than 150,000 messages.
“With Covid, do we have to go to the end or go to the end?” said Cox, a former official of the CDC. “It’s frustrating to see that we are not doing better when I know we can do better.”
At the end of last year, the United States sequenced about 3,000 samples every week. Earlier this year, the Centers for Disease Control and Prevention set a goal to increase this number to 6,500 samples released by American laboratories every week within two weeks.
Armstrong said that during the week of January 2-8, US laboratories sequenced 10,619 samples. However, he pointed out that the CDC may not be able to provide credit for most of them, and only 1,001 samples were from the previous four weeks.
