Did the COVID-19 Outbreak Really Start from Eating Pangolins?

Did the COVID-19 Outbreak Really Start from Eating Pangolins?
The COVID-19 pandemic has sparked widespread debate regarding its origins. One of the most prominent theories points to the Pangolin as a potential intermediate host that transmitted the virus to humans. But is this actually true?

The Genetic Connection
Research into the SARS-CoV-2 virus (the virus that causes COVID-19) revealed that its genetic sequence is highly similar to coronaviruses found in bats. However, because bats and humans rarely come into direct contact in a way that would trigger a massive outbreak, scientists looked for an "intermediate host"—an animal that could have contracted the virus from bats and then passed it on to humans.

Pangolins became the primary suspects when researchers discovered a coronavirus in Malayan pangolins that shared approximately 90% to 91% of its genome with SARS-CoV-2. More importantly, the Receptor-Binding Domain (RBD)—the part of the virus that allows it to "unlock" and enter human cells—was found to be nearly identical (around 99% similarity) to the version found in humans.

Consumption and the Wildlife Trade
The theory gained more traction because pangolins are among the most trafficked mammals in the world. Despite being protected, they are often sold in "wet markets" for their meat, which is considered a delicacy in some cultures, and their scales, which are used in traditional medicine.

If an infected pangolin was handled or consumed in a market setting (like the one in Wuhan, China), it could provide the perfect environment for the virus to jump from animal to human.

Is it Fact or Still a Theory?
While the genetic evidence is compelling, scientists remain cautious. Here are the key points to consider:

Missing Link: Although the pangolin coronavirus is very similar, it is not identical enough to be the direct ancestor of SARS-CoV-2.
Other Possibilities: Other animals, such as civets or even domestic pets, were also studied, but pangolins showed the closest match in the specific area that affects human infection.
The "Spillover" Event: Most experts agree that the virus likely originated in bats, but whether it went through a pangolin, another animal, or directly to humans is still a subject of ongoing scientific investigation.
Conclusion
While it cannot be stated with 100% certainty that eating a pangolin started the pandemic, the pangolin remains a "strong candidate" for the intermediate host. This situation serves as a stark reminder of the risks associated with the illegal wildlife trade and the consumption of exotic animals, which can lead to the emergence of new zoonotic diseases.
