Washington resident dies from avian influenza after cattle exposure

Washington state health officials reported the death of a Yakima County resident who was hospitalized with severe illness after contracting avian influenza through exposure to infected dairy cattle. The individual had underlying health conditions, according to the Yakima Health District.

Andrew Pekosz, professor and vice chair of the W. Harry Feinstone Department of Molecular Microbiology and Immunology at Johns Hopkins Bloomberg School of Public Health, said the virus has persisted in dairy cattle for several years and continues to spread. He noted that the genetic sequence of the virus shows it remains active.

The state has recorded three avian influenza cases this year, all linked to people working on or contacting dairy farms. Pekosz emphasized that the risk to the general public is low and that most people need not be concerned, though the death underscores the need for continued vigilance.

Dr. William Schaffner, professor of preventive medicine at Vanderbilt University Medical Center, warned that while the virus does not currently transmit easily between humans, it could potentially mutate to do so. He urged people, especially those with chronic illnesses, to receive the seasonal influenza vaccine, noting that flu activity is already elevated in Washington and across the country.

Both experts recommended vaccination as a precautionary measure during the ongoing flu season, which is expected to continue through the winter months.
