Strains of the influenza virus that primarily infect birds, but can also infect humans.
This type of flu is most often contracted by contact with sick birds. It can also be passed from person to person.
Symptoms begin within two to eight days and can seem like the common flu. Cough, fever, sore throat, muscle aches, headache and shortness of breath may occur. Symptoms may worsen into gut issues, breathing issues, or CNS changes.
The disease can carry a high mortality in humans. Some antiviral drugs, if taken within two days of symptoms, may help.
Bird flu, or avian influenza, has once again captured global attention due to recent outbreaks impacting both wildlife and poultry industries. This highly contagious virus primarily affects birds but has raised concerns due to its occasional transmission to humans. Health authorities worldwide are closely monitoring cases to prevent a potential pandemic. The economic impact has been substantial, with mass culling of birds in affected regions, leading to disruptions in the poultry supply chain. As researchers work to contain the spread, heightened biosecurity measures and public awareness campaigns remain crucial in mitigating the threat posed by this recurring disease.
Bird flu, also known as avian influenza, is a contagious viral disease that primarily affects birds but can also infect mammals, including humans: How it spreads
Bird flu viruses are present in the intestines of wild birds, but usually don’t make them sick. Infected birds shed the virus in their saliva, nasal secretions, and feces, which can contaminate surfaces and excretions. Susceptible birds become infected through contact with these contaminated areas.
Symptoms
Symptoms vary depending on the strain of virus and the species affected. Symptoms in humans include: Difficulty breathing
Fever over 103°F (40°C)
Confusion or altered mental state
Severe fatigue or inability to wake up
Severe headache
Stiff neck
How to prevent
- Wash surfaces that have come into contact with raw poultry, meat, seafood, or eggs with hot, soapy water
- Cook food fully
- Avoid raw dairy products
How to treat
Bird flu is usually diagnosed by testing swabs taken from the nose and throat. Several anti-viral medications used to treat human flu are also effective for bird flu.
