The US has seen no reported cases of bird flu in humans for three months, sparking concern among health officials and experts. While there are possible explanations, including a natural decline in infections due to seasonal migration patterns of wild birds, some believe that government cuts and concerns over immigration may be contributing factors.
Jennifer Nuzzo, director of the Pandemic Center at Brown University, says “we just don’t know why” there haven’t been any new cases. Despite the fact that 70 people have been infected in the US since last year, mostly with mild symptoms, officials are urging vigilance and calling for increased testing.
The H5N1 bird flu virus has spread widely around the world, including the US, where it has affected farm workers and cattle. However, cases among humans have declined significantly, with only three people tested in March, April, and May this year, compared to at least 50 tests per month in late 2024.
Some experts believe that government cuts may be affecting the ability to detect mild infections, as well as concerns over immigration may be deterring immigrant farm workers from coming forward for testing. However, others argue that a natural decline in cases due to seasonal patterns may also be contributing to the lack of new infections.
The Centers for Disease Control and Prevention (CDC) still considers the risk to the general public low, but warns that bird flu could evolve into a more severe form if not addressed. Research is ongoing to better understand the virus and its potential for pandemic spread.
Recent studies have found evidence suggesting some cases may be going undetected, with one study finding that 7% of dairy workers had antibodies to H5N1. Experts are calling for increased surveillance to detect mild infections and prevent further spread of the virus.
