Understanding Highly Pathogenic Avian Influenza (HPAI)
What is HPAI?
Highly Pathogenic Avian Influenza (HPAI), commonly known as bird flu, is a severe viral infection that primarily affects bird species. It is caused by avian influenza viruses, with the H5N1 strain being particularly lethal.
Which Species are Most Affected?
Waterfowl: Species like swans, geese, and ducks often carry HPAI without showing symptoms.
Raptors: Birds of prey such as eagles, hawks, and owls are highly susceptible and often suffer severe illness.
Domestic Poultry: Chickens and turkeys can experience rapid disease progression and high mortality rates.
How is HPAI Transferred?
HPAI spreads through direct contact with infected birds or their secretions, including feces and respiratory droplets. Contaminated environments and objects can also facilitate the spread of the virus. The virus thrives in cold and damp conditions, which can extend its survivability outside of a host.
Impact on Humans
While HPAI predominantly affects birds, it can pose a risk to humans.
Human infections can result in severe respiratory illness.
Activities that increase the risk of exposure include handling infected birds,
cleaning bird feeders, and visiting areas with a high density of birds.
It is recommended to avoid handling wild birds and to practice good hygiene,
such as washing hands thoroughly after any potential exposure.
Impact on Domestic Birds
Domestic birds are highly susceptible to HPAI. Symptoms in domestic birds include respiratory distress, decreased egg production, and sudden death (CDC) (NCCID). Implementing strict biosecurity measures on farms and keeping domestic birds away from wild birds are crucial steps in preventing outbreaks.
Impact on Pets and Other Mammals
HPAI can also infect mammals, including pets such as cats and dogs, though this is less common. Mammals can contract the virus through close contact with infected birds or contaminated environments. In rare cases, HPAI can be severe or fatal for pets. To protect pets, it is advisable to keep them away from wild birds and ensure they do not interact with bird feeders or bird baths.
Our Commitment
At the Ojai Raptor Center, we prioritize the health and safety of our birds; both patients and ambassadors with heightening our biosecurity measures to protect against Highly Pathogenic Avian Influenza (HPAI). New patients are initially examined in an outdoor examination room before being admitted to our hospital, ensuring early detection. We are also constructing a separate quarantine enclosure for observing suspected cases before they integrate with other patients. All cleaning and sanitization practices follow guidelines from the CDC and NCCID, ensuring effective virus elimination. To further safeguard our ambassador birds and educational team, we have established stricter protocols to separate and protect their living and preparation areas, including their enrichment items. These measures ensure the wellbeing of all our avian residents and visitors.
