A chilling possibility looms: a bird flu pandemic could be far more devastating than COVID-19. This stark warning comes from France's Institut Pasteur, highlighting the potential dangers of the avian influenza virus.
The highly pathogenic avian influenza, often referred to as bird flu, has already caused the culling of hundreds of millions of birds, impacting food supplies and pushing prices upward. But here's where it gets concerning: the virus is now spreading among wild birds, poultry, and mammals.
- The core concern? The virus mutating to spread easily between humans.
Marie-Anne Rameix-Welti, medical director at the Institut Pasteur’s respiratory infections centre, explained that if the virus adapts to humans and becomes transmissible from person to person, it could unleash a pandemic.
The Institut Pasteur played a crucial role in developing and sharing COVID-19 detection tests early in the previous pandemic.
- Why is this bird flu different? Unlike seasonal flu, we have no existing antibodies to protect us from the H5 bird flu strain currently affecting birds and mammals.
Rameix-Welti emphasizes that, unlike COVID-19, which primarily affected vulnerable populations, flu viruses can strike down even healthy individuals, including children. She further warned that a bird flu pandemic could be even more severe than the one we've just experienced.
But there's a silver lining: Compared to the start of the COVID-19 pandemic, we're now better prepared. We have preventative measures, vaccine candidates ready, and the ability to manufacture vaccines quickly. We also have stocks of specific antivirals that could be effective against this avian influenza virus.
There have been cases of human infections with H5 bird flu viruses in the past, often linked to close contact with infected animals. The World Health Organization (WHO) reported nearly 1,000 outbreaks in humans between 2003 and 2025, primarily in Egypt, Indonesia, and Vietnam, with a 48% fatality rate.
Gregorio Torres, head of the Science Department at the World Organization for Animal Health, reassures us that the risk of a human pandemic remains low. He suggests we can still enjoy our lives, including eating chicken and eggs.
Controversially, while the risk is currently low, the potential severity demands constant vigilance and preparedness.
