COVID-19 origins, highlighting zoonotic spillover as most likely but emphasizing missing data from China.">
an expert panel convened by the World Health Organization (WHO) to probe the origins of the COVID-19 pandemic has released its final report, but definitive answers remain elusive [1], [3]. The WHO Scientific advisory Group for the Origins of Novel Pathogens (SAGO), comprised of 27 independent, international experts, published its findings, pointing towards zoonotic spillover as the most probable origin, while stressing that crucial information is still outstanding.
SAGO’s Findings and Recommendations
The SAGO report, released on Friday, June 27, 2025, considered available evidence for the main hypotheses surrounding the origins of COVID-19. While the report suggests that the “weight of available evidence…suggests zoonotic spillover…either directly from bats or through an intermediate host,” it also acknowledges that a comprehensive evaluation of all hypotheses is hindered by the lack of complete data.
Did You Know? The first known case of COVID-19 can be traced back to Wuhan,China,in late 2019. Understanding the virus’s journey from its source to humans is crucial for preventing future outbreaks.
Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, expressed gratitude to the SAGO members for their dedication and emphasized that “all hypotheses must remain on the table, including zoonotic spillover and lab leak.” He reiterated the WHO’s appeal to China and other nations possessing relevant information to share it openly,for the sake of global pandemic preparedness.
Data Gaps and China’s Role
A important obstacle in the investigation has been the lack of access to key data. The WHO has requested that China share hundreds of genetic sequences from individuals infected early in the pandemic, detailed information about animals sold at Wuhan markets, and data regarding laboratory work and biosafety conditions in Wuhan. To date, this information has not been shared with SAGO or the WHO.
Pro Tip: Openness and international collaboration are essential for effectively investigating the origins of novel pathogens and preventing future pandemics.
The WHO’s efforts to understand the origins of COVID-19 began with a resolution adopted by Member States at a Special Session of the World Health Assembly in late 2020. This led to a joint mission between international and Chinese experts to china in early 2021, resulting in a report published in March of that year.
the Ongoing Quest for Answers
Dr. Marietjie Venter, Chair of SAGO, emphasized the moral and ethical imperative of understanding the origins of SARS-CoV-2. “understanding the origins of SARS-CoV-2 and how it sparked a pandemic is needed to help prevent future pandemics, save lives and livelihoods, and reduce global suffering,” she stated.
The WHO remains committed to the investigation and welcomes any further evidence regarding the origins of COVID-19. SAGO stands ready to review any new information that may become available. The search for the definitive origin story continues, with the hope of strengthening global defenses against future pandemics.

Evergreen Insights: Understanding COVID-19 Origins
The investigation into the origins of COVID-19 is not just about assigning blame; it’s about understanding the complex interplay between humans, animals, and the environment that can lead to pandemics. Identifying the source of the virus allows for the development of targeted interventions to prevent future outbreaks, such as improved surveillance of animal populations, enhanced biosecurity measures in laboratories, and stricter regulations on wildlife trade.
Furthermore, understanding the origins can help address misinformation and conspiracy theories that have plagued the pandemic response. By providing a clear and evidence-based narrative, public health officials can build trust and encourage adherence to preventative measures.
Frequently asked questions About COVID-19 Origins
What is the most likely origin of COVID-19?
The WHO’s SAGO report suggests that zoonotic spillover, the transmission of the virus from animals to humans, is the most likely origin. However, further investigation is needed to confirm the exact animal source and the mechanisms of transmission.
Why is it so difficult to determine the exact origin of COVID-19?
Several factors contribute to the difficulty, including the time elapsed since the initial outbreak, the lack of complete data from the early stages of the pandemic, and the complexity of tracing the virus’s journey through animal populations.
What can be done to prevent future pandemics?
Improved surveillance of animal populations, enhanced biosecurity measures in laboratories, stricter regulations on wildlife trade, and increased international collaboration are crucial steps in preventing future pandemics.
What role does international cooperation play in investigating disease origins?
International cooperation is essential for sharing data, expertise, and resources, which are all necessary for effectively investigating the origins of novel pathogens and preventing future outbreaks.
How can the public stay informed about the latest findings on COVID-19 origins?
Rely on reputable sources of information, such as the WHO, national public health agencies, and peer-reviewed scientific publications.Be wary of misinformation and conspiracy theories circulating online.
