CDC Warns of Undetected Bird Flu Infections Among U.S. Farm Workers

A recent study reveals asymptomatic cases, prompting calls for expanded testing and protective measures.

A CDC study found that a number of H5N1 infections in dairy farm workers went undetected, with some workers showing antibodies despite recalling no symptoms.
Experts emphasize the need for more aggressive testing and enhanced personal protective equipment (PPE) for farm workers exposed to the virus.
The CDC maintains that the current strain poses a low risk to the general public, with no evidence of human-to-human transmission so far.
New recommendations include testing all exposed farm workers regardless of symptoms and offering antiviral treatment to high-risk individuals.
Challenges persist due to resistance from farmers, difficult working conditions, and limited healthcare access for many farm workers.
