Overview

• The WHO’s Scientific Advisory Group on New Pathogens (SAGO) presented findings that did not conclusively determine whether the virus emerged through animal spillover or a laboratory incident.
• Tedros Adhanom Ghebreyesus emphasized that the investigation is ongoing and that all leading hypotheses on COVID-19’s origin remain on the table.
• The WHO called on China to provide unshared raw data from early Wuhan cases, including virus samples and detailed patient records.
• Most scientists support a zoonotic spillover via an intermediate host; US agencies such as the FBI and Department of Energy continue to consider a laboratory leak scenario.
• Officials warned that resolving these unanswered questions is crucial for preventing future pandemics and addressing the evolving global impact of COVID-19.
