GABON – Libreville, the capital of Gabon, has recently become the epicenter of concern as the World Organisation for Animal Health (WOAH) confirmed a resurgence of the highly contagious H5N1 avian influenza, commonly known as bird flu.

This marks the first reemergence of the virus in the country since 2022.

The resurgence of the H5N1 strain in Gabon is alarming, particularly given its devastating impact on poultry worldwide.

Over the past few years, this virulent form of bird flu has decimated poultry populations globally, resulting in the death or culling of hundreds of millions of birds.

The virus’s increasing ability to cross species boundaries, with cases now confirmed in mammals such as cows in the United States, adds to the growing concerns.

Gabonese authorities traced the source of the outbreak to the Mont Bouet poultry market in Libreville.

Routine surveillance activities detected the H5N1 virus in samples collected from the market.

However, the report to WOAH highlighted a significant issue: the infected birds came from farms that could not be identified, indicating a critical lapse in biosecurity measures.

This lack of traceability complicates efforts to determine the outbreak’s origin, hindering effective containment strategies.

The challenge in tracing the virus’s source poses a major obstacle in controlling its spread.

Without knowing how the virus entered the market, implementing targeted control measures becomes problematic.

Experts warn that the virus could further spread through wild bird populations or infect additional farms, leading to extensive damage.

In response, the Gabonese government is expected to enact several measures to curb the outbreak.

These measures may include establishing quarantine zones around the affected market, restricting the movement of poultry and poultry products, and possibly culling infected birds.

Strengthening biosecurity protocols at poultry farms will also be essential to prevent future outbreaks.

The international community is closely monitoring Gabon’s response to this bird flu incident. Effective containment strategies could serve as a model for other countries facing similar threats.

Additionally, ongoing research into the interspecies transmission of H5N1 is crucial to mitigate the risks posed by this zoonotic virus, which can potentially jump from animals to humans.
