Urgent Alert: Potential Human-to-Human Avian Flu Transmission Under Investigation in Missouri

2024-09-27

Summary of the Investigation

The CDC has initiated an investigation into eight potential cases of human infection linked to the H5N1 avian influenza virus in Missouri, following the state's first reported case last month.

Details of the Cases

Symptoms have been identified in at least one household member and six healthcare workers who had contact with the initial patient. The rapid development of the situation indicates a heightened risk.

Current Status of H5N1 Cases in the U.S.

So far this year, 14 confirmed human cases of H5N1 have been reported in the U.S., primarily among agricultural workers with direct contact with infected birds or livestock.

Healthcare Protocols Under Review

The CDC plans to conduct antibody testing for healthcare workers who had contact with the index patient before appropriate precautions were taken.

Pending Test Results

None of the individuals connected to the H5N1 case have tested positive yet, but serology testing results are pending.

Broader Context of Respiratory Illnesses

The CDC's updates indicate low seasonal influenza and RSV activity, while COVID-19 metrics have declined.

Vaccine Uptake Concerns

Alarming low vaccine uptake for the flu and COVID-19 among adults raises concerns about community immunity.

Public Health Recommendations

Health officials emphasize the importance of remaining informed and considering vaccination to bolster immunity against potential outbreaks.
