When the US Department of Agriculture announced late Sunday that it had publicly posted new data from its investigation into a bird flu outbreak in cattle, scientists eagerly searched a well-known platform used globally to share the genetic sequences of viruses. <\/p>\n

The sequences weren\u2019t there. As of Tuesday morning, they still aren\u2019t. <\/p>\n

Researchers looking to track the evolution and spread of H5N1 say the information that was posted \u2014\u00a0raw data on a US server \u2014 isn\u2019t very useful and is anything but transparent.\u00a0They also say the government\u2019s release of information in the outbreak, which was confirmed in cattle almost a month ago, has been painfully slow. <\/p>\n

After Sunday\u2019s announcement by the <\/strong>USDA, Dr. Rick Bright, an immunologist and vaccine researcher who led the Biomedical Advanced Research and Development Authority from 2016 to 2020, said he immediately called his contacts at the database, called the Global Initiative on Sharing All Influenza Data, or GISAID, to make sure he wasn\u2019t missing something. <\/p>\n

\u201cI said \u2018Look, just tell me: Do you have data?\u2019 and they said \u2018No,\u2019\u201d Bright said. <\/p>\n

After checking even parts of the database where people can post rough drafts of sequences prior to full public release, Dr. Lucas Freitas, a Brazilian data scientist who is the GISAID curation lead, confirmed there are no new sequences posted by the USDA since its announcement. <\/p>\n

\u201cWe wouldn\u2019t miss it,\u201d said Peter Bogner, founder and president of GISAID.\u00a0\u201cH5 is the reason GISAID came about to begin with. It raises antennas.\u201d <\/p>\n

The highly pathogenic avian influenza strain H5N1 has decimated bird populations around the world, and in recent years, has moved into a growing variety of mammals, raising concern that it\u2019s a step closer to becoming a virus that can spread efficiently in people. <\/p>\n

When the USDA confirmed that H5N1 had been detected in dairy cows in Texas and Kansas on March 25, the news put infectious disease experts on alert, and they were eager to get more information to see how the virus had changed to target a new host. The USDA\u2019s Animal and Plant Health Inspection Service, or APHIS,<\/strong> says H5N1 has now been found in 32 herds in eight states. <\/p>\n

But weeks have gone by, and little data on the US outbreak has been shared with the global scientific community. <\/p>\n

In its notice posted Sunday, APHIS said it had shared 239 genetic sequences from the H5N1 outbreak \u201cfrom cattle, cats, chickens, skunk, racoon, grackle, blackbird, and goose.\u201d <\/p>\n

The agency said it \u201croutinely publishes\u201d on GISAID, but in the interest of public transparency and \u201censuring the scientific community has access to this information as quickly as possible \u2026\u201d it was \u201calso rapidly sharing\u201d sequences to a US database maintained by the National Library of Medicine. <\/p>\n

The announcement suggested to many scientists that the information would be found in GISAID, which has been <\/strong>critical to tracking the evolution of the virus that causes Covid-19 as it moves around the world. <\/strong>Many countries, including the United States, use GISAID to quickly share genetic sequences \u2014 the exact order of four chemical building blocks that make up the blueprints of each virus. <\/p>\n

Instead, the USDA uploaded raw sequencing data, called FASTQ files, to the National Library of Medicine database, which is available to the public.\u00a0These FASTQ files, however, lack the critical information necessary to help scientists track the evolution of the virus, such as the exact date the sample was collected and what state it came from. <\/p>\n

Scientists do use raw data when tracking the evolution of a virus, but they also typically use it in concert with the type of information that is typically posted to GISAID: consensus sequences, known as FASTA files, which have been refined and cleared of contamination and mistakes. Consensus sequences typically give more information about where the sample was collected and when, helping researchers better understand how a virus is changing over time. <\/p>\n

Researchers say it\u2019s not clear how recently the samples that are the basis for the raw data were taken.\u00a0The only dates posted say \u201c2024,\u201d and the locations are only listed as \u201cUSA.\u201d\u00a0There\u2019s no information on how the samples were obtained \u2014 whether they come from swabs of an animal\u2019s respiratory tract its <\/strong>skin, or somewhere else. <\/p>\n

\u201cAPHIS typically posts curated sequence data on the GISAID platform. However, in order to make sequence data public as soon as possible, APHIS uploaded these unanalyzed sequence data files to NCBI,\u201d Weir wrote in the emailed response. <\/p>\n

\u201cThese sequences will not be curated before posting, but this approach will allow us the most rapid path to posting sequence information. APHIS will continue to work as quickly as possible to publish to GISAID curated files that incorporate and analyze relevant epidemiologic information along with the sequence data,\u201d Weir said. <\/p>\n

It\u2019s also not clear whether the latest release represents all the genomes the agency has. <\/p>\n

Dr. Michael Worobey, a professor of ecology and evolutionary biology at the University of Arizona, said the USDA was making a mistake by not sharing all the information it has as quickly as possible. <\/p>\n

\u201cThere\u2019s a whole community around the world of people like me and my colleagues, who have a lot of experience with this and often can see things or do analyses that might show something that others have missed,\u201d Worobey said. <\/p>\n

\u201cYou don\u2019t want essentially one group to be the only ones looking at the data. You want everyone, all the experts around the world to be able to do that,\u201d Worobey added. <\/p>\n

Dr. Tom Inglesby, who directs the Johns Hopkins Center for Health Security at the Bloomberg School of Public Health, said USDA\u2019s public release of the raw data was a step in the right direction, but it didn\u2019t go far enough. <\/p>\n

\u201cThe additional information would be quite useful for the public and for scientists and public health agencies, research organizations to understand all of the data that has been collected so far, what farms have been tested, when they were tested, what the sampling strategy is, overall, what kind of testing is going on now, around the country,\u201d he said. <\/p>\n

\u201cNow that we know that there are asymptomatic cows that have tested positive, what\u2019s the strategy to understand the extent to which cows are infected that don\u2019t have symptoms in other herds? Because I think the most important objective here is to get a full picture of the outbreak.\u201d <\/p>\n

Influenza viruses change quickly and have caused some of the most devastating pandemics throughout history. <\/p>\n

\u201cWhat we\u2019re seeing right now is chapter one of <\/strong>the book that keeps people like me and many infectious disease epidemiologists up at night,\u201d said Dr. Michael Mina, who is chief scientific officer of the telehealth company eMed and an expert in the epidemiology, immunology and spread of infectious disease. <\/p>\n

The Covid pandemic was bad, but Mina said a pandemic caused by this virus could be worse. <\/p>\n

\u201cThe genie is not out of the bottle yet, and that\u2019s a good thing,\u201d Mina said, but given the potential consequences of letting the virus spread unchecked, \u201cIt\u2019s a little bit hard to suggest we could be doing too much right now.\u201d <\/p>\n

Scientists have followed H5N1 for roughly two decades as it ripped through populations of wild and domestic birds and more recently marine mammals like sea lions, but human-to-human spread after contact with animals has been sporadic and not sustained, suggesting the virus has not mutated enough to become a fully human pathogen. There\u2019s been no evidence of person-to-person spread in the current US outbreak, according to the U.S. Centers for Disease Control and Prevention. <\/p>\n

\n
    <\/ul>\n<\/div>\n

    Humans have been infected after contact with animals, however \u2014 a chilling reminder that the virus still has us in its sights and requires close monitoring. <\/p>\n

    \u201cIt\u2019s so critical that the US government is being as transparent as they can right now, overly transparent, and sharing all of these sequences and all of this data so the world can look at it and make their own risk assessments and start making their own vaccine if they need to in their own countries instead of waiting for the United States to say what\u2019s good and what\u2019s bad,\u201d said Bright, who is CEO of Bright Global Health in Washington, DC. <\/p>\n

    \u201cWhat would we say if this particular virus did get out of control?\u201d Bright said. \u201cWould we look back on this last two or three months and say: \u2018I wish we would have done something else; I wish we would have been more transparent; I wish we would have shared all these sequences so the world can get ready for this?\u2019\u201d <\/p>\n<\/p>\n
