WHO’s Alarm

Seattle – The recent surge in bird flu cases, particularly among dairy cows, has raised alarms with the World Health Organization (WHO). The WHO expressed concerns over the potential transmission of the bird flu to other animals and humans.

Understanding Avian Influenza

Avian influenza, commonly known as bird flu or the H5N1 virus, is caused by infection with avian Type A influenza viruses. These viruses primarily circulate among wild aquatic birds worldwide but can also infect domestic poultry and other animal species.

Evolution of the Outbreak

Initially affecting ducks and chickens when it emerged in 2020, the current outbreak has expanded to include cows and goats. Recently, the WHO reported the first human case of bird flu transmission from contact with an infected mammal in Texas. The patient experienced conjunctivitis (pink eye) as the only symptom and is currently recovering.

Global Concerns

Health officials have labeled the H5N1 bird flu as a global zoonotic animal pandemic, highlighting its potential to evolve and acquire the ability for human-to-human transmission, although such transmission has not yet occurred.

Rare Human Infections

According to the Centers for Disease Control and Prevention (CDC), human infections with bird flu are rare, as these viruses typically do not infect people. However, exposure to infected birds’ saliva, mucous, or feces can lead to human infections, particularly among those in close contact without proper protection.

Symptoms and Severity

Symptoms of bird flu in humans vary, ranging from mild flu-like symptoms to severe respiratory illnesses like pneumonia, with some cases resulting in death. Common symptoms include fever, cough, sore throat, and muscle aches, while less common ones include diarrhea and seizures.

Host Species and Transmission

Bird flu viruses have been isolated from over 100 species of wild birds globally, with dabbling ducks considered primary hosts. While many host species may not exhibit symptoms, the virus is highly contagious among birds and can spread through direct contact or contaminated surfaces.

Conclusion: Staying Informed and Protected

As bird flu cases continue to emerge across the country, staying informed about the virus’s transmission and symptoms is crucial. Proper precautions, including avoiding contact with infected birds and practicing good hygiene, can help mitigate the risk of human infections.
