Summary

The WHO reiterated calls for China to provide data on COVID-19 origins, five years after the virus emerged in Wuhan.

The lack of transparency has hindered understanding of the pandemic’s early stages. Initial theories pointed to animal-to-human transmission via Wuhan’s wet market, but speculation about a lab leak persists.

A 2021 WHO-China report deemed a lab leak “extremely unlikely,” though no firm conclusions were reached. China has rejected further investigations.

While most scientists favor natural origins, debate remains, complicating efforts to prevent future pandemics.
