Last spring, both "chicken" and "milk" made headlines in the U.S. and India.
The reason? Avian Influenza (H5N1), better known as bird flu.
A virus that once only affected chickens has now reached cows—and even humans.
Which raises the question:
"Isn’t this just an animal disease?"
Well, judging by the current situation, it’s clearly more than that.
What exactly is bird flu?
Bird flu is caused by avian influenza viruses, which mostly spread among birds. The H5N1 strain is classified as highly pathogenic, with a high mortality rate and rapid spread potential.
It typically affects poultry like chickens and ducks. Human infections used to be rare, but in recent years, cases have steadily increased, and the ways the virus spreads are changing, raising global concern.
Recent developments
- WHO reports: 986 confirmed cases and 462 deaths globally (approx. 47% fatality rate)
- USA (2025): A dairy worker was infected
- India (2025): Human infection confirmed after exposure to infected birds
- Experts warn: Potential airborne transmission is under investigation
How does it spread?
- Direct contact with infected birds, their droppings, feathers, or bodily fluids
- Consuming undercooked poultry or eggs: Cooking thoroughly is safe, but risk exists before preparation
- Airborne transmission? Some scientists now believe the virus may spread through dust or air in farms
What are the symptoms in humans?
- High fever, cough, sore throat, muscle aches
- In severe cases: pneumonia, respiratory failure, kidney problems
- Delayed treatment can increase risk of death
Is there a vaccine?
There is no commercial vaccine currently available to the general public. Some vaccines exist for high-risk groups or for research purposes only.
However, candidate vaccines are under development in the U.S. and Europe in preparation for a possible pandemic.
How to protect yourself
- Avoid eating raw or undercooked poultry and eggs
- Do not touch live birds in markets or farms
- Practice good hygiene (wash hands, wear masks)
- Seek medical attention if symptoms appear
- Report suspicious animal deaths to health authorities
Bird flu isn't just a poultry problem
When we hear “bird flu,” we usually picture chickens or ducks. But recent developments show us that this virus is crossing boundaries.
A virus that spreads to humans is not just a health issue—it’s a test of our global response systems and preparedness.
“Knowledge and preparation are the best vaccines.”
It’s not the virus we should fear the most—it's ignorance and indifference.
Science gives us the tools to predict and prevent outbreaks. Don’t scroll past the headlines—understand what's happening, and take steps to protect your family and your community.
Bird flu might not be a full-blown crisis yet,
but the warning signs are loud and clear.
