(NewsNation) — Bird flu may be spreading undetected in humans, according to a recently released report from the Centers for Disease Control and Prevention
Data posted last week in the CDC’s Morbidity and Mortality Weekly Report suggests the spread of bird flu between dairy cattle and humans has gone unchecked, including in states where cattle have not tested positive.
This comes after the Trump Administration froze external communications from the agency, which interrupted the agency’s weekly report.
Researchers analyzed blood samples from 150 veterinarians who worked with dairy and nondairy cattle across the country and found that three of them had antibodies to bird flu, which suggested a recent infection.
None of them reported any flu-like symptoms and did not work with any cattle that were infected, and one reported working with infected poultry.
Bird flu: Human-to-human transmission?
There have been no reported cases of human-to-human transmission so far, but there is concern about variants developing if infections in humans spread.
Nearly 70 people have been infected with bird flu across the country, with one person in Louisiana dead.
