Five years after the COVID-19 pandemic began, the question of the origin of the SARS-CoV-2 virus still remains without a definitive answer. Did the virus spread to humans naturally, or did it leak from a laboratory? In recent months, the topic has regained prominence, particularly in the context of changes in information policy in the United States. Let us look at the latest findings and controversies surrounding the source of the pandemic.
Current positions of US intelligence
In January 2025, the Central Intelligence Agency (CIA) published an assessment stating that it is more likely that COVID-19 originated from a laboratory than from a natural reservoir, such as the market in Wuhan. However, the agency noted that it has “low confidence” in this assessment, based on existing data rather than new evidence .
Other intelligence agencies, such as the FBI and the US Department of Energy, have also expressed support for the laboratory leak theory, though with varying degrees of certainty. Even so, the lack of conclusive evidence means the topic remains open and controversial.
Changes in US information policy
In April 2025, the administration of President Donald Trump made a significant change in how information about COVID-19 is presented. Official government websites, such as covid.gov and covidtests.gov, were redirected to a new page promoting the laboratory leak theory as the only true source of the pandemic .
The new page contains accusations against former public health officials, such as Dr. Anthony Fauci, and international institutions, including the World Health Organization (WHO). Critics argue that this presentation of information is one-sided and may mislead the public.
The position of the scientific community
Many scientists still believe that the most likely source of SARS-CoV-2 is a natural transmission of the virus from wild animals to humans. Studies suggest that the virus may have originated in bats and spread to people through an intermediate host, such as pangolins or other animals sold at the Wuhan market .
However, the lack of full cooperation from China and limited access to data from the early period of the pandemic make it difficult to definitively determine the source of the virus. Consequently, the scientific community calls for further independent research and greater transparency.
The impact of politics on the debate over the virus's origin
The debate over the origins of COVID-19 has become highly politicized, especially in the United States. Changes in information policy and public accusations against specific individuals and institutions may affect how society perceives the facts.
Experts warn that politicizing scientific issues can lead to disinformation and undermine trust in public health institutions. They also stress the need to separate scientific research from political influence in order to ensure the objectivity and reliability of findings.
The origin of the SARS-CoV-2 virus remains an unresolved question. Although some intelligence agencies lean toward the laboratory leak theory, the lack of conclusive evidence means the natural transmission theory is still considered probable. However, politicization of the debate may hinder objective research and understanding of the source of the pandemic.
