Avian flu is once again high on the public health radar. This virus is increasingly being detected in wild birds, poultry, livestock, and even humans. Some dairy workers have reported mild cases, and wastewater surveillance continues to uncover its presence.

Dr. Daniel Teres, a retired faculty member of Tufts University School of Medicine and a critical care physician, explains the current detection approach. Many emergency departments, urgent care centers, and primary care offices use point-of-care testing that screen for COVID, Influenza A, Influenza B, and sometimes RSV. However, when cases test negative for seasonal Influenza A subtypes—especially in hospitalized patients—samples are sent to one of over 100 state virology labs for genetic sequencing. This process takes days, underscoring the urgent need for faster testing.

If human-to-human transmission begins, local outbreaks could follow—and communities are not fully prepared. Senior living communities should take precautions now, ensuring symptomatic residents and staff are screened and isolated as needed. Emergency departments must also work toward separating individuals with suspected avian flu to limit exposure in waiting areas. While vaccine development is underway, the good news is that some sensitive Influenza A tests may detect avian flu since it is a subtype.

Being proactive today can make all the difference. Avian flu may not be widespread among humans yet, but preparation is key. Screen, isolate, and ensure your community is ready.
