Bird flu surges in these US states with reports of new outbreaks

The spread of Avian influenza A (H5N1), commonly known as bird flu, continues to pose a threat in the United States, with Hawaii being the latest state to report cases of the virus. The Hawaiian Department of Agriculture (HDOA) recently confirmed bird flu in a backyard flock of various birds in Central Oahu, where at least 10 birds, including ducks, geese, and a zebra dove, were found dead.

Highly pathogenic avian influenza (HPAI) causes severe illness with a high mortality rate among affected birds, according to the HDOA. The presence of bird flu in Hawaii was detected through the National Wastewater Surveillance System, marking the first confirmed detection in the state. As a result, a quarantine order has been issued for the infected site, requiring the depopulation of all birds on the property and thorough cleaning and disinfection.

The strain of bird flu found in Hawaii is the same one that has infected dairy cows and domestic poultry in mainland states like California. California has reported 27 human cases of bird flu, with 335 dairy farms in Central California affected by the virus. The California Department of Public Health (CDPH) is closely monitoring the situation and distributing protective gear to individuals who work closely with poultry and cows.

In addition to Hawaii and California, Arizona reported its first bird flu outbreak in poultry at a commercial farm in Pinal County. Experts believe that the surge in bird flu cases is linked to the Pacific Flyway, where birds migrate south for the winter. While the potential for human infection is low, precautions are being taken to prevent the spread of the virus.

The CDC has warned that human infections are rare but can occur through contact with infected animals or contaminated surfaces. Symptoms of bird flu in humans can range from mild respiratory issues to more severe complications like pneumonia and seizures.

Experts like Sam Scarpino, PhD, and Dr. Jacob Glanville are urging for decisive action to be taken to prevent further spread of the virus. This includes increased testing and surveillance, vaccination of dairy cows, and education for healthcare professionals on how to differentiate bird flu cases from seasonal influenza.

In conclusion, the ongoing outbreak of bird flu in the U.S. is a cause for concern, but with proper precautions and proactive measures, the spread of the virus can be controlled. It is essential for individuals to avoid contact with sick or dead birds and animals and to stay informed about the latest developments in the outbreak.
