Pestilence: Over 100 'BSL-4' Bioweapons Labs Now Operate Worldwide

Over 100 'BSL-4' Bioweapons Labs Now Operate Worldwide, With More Under Construction

Over the past few years, the world has entered a new era of high-containment biological research—marked by a dramatic expansion of laboratories capable of working with the most lethal viruses known to man.

These include facilities built to the highest biosafety standard, Biosafety Level 4 (BSL-4), and they carry not only the broken promise of defending us from pandemics but also the danger of enabling bioweapons creation, whether by accident or deliberate misuse.

Strikingly, a May 2025 Journal of Public Health study found that more than 90% of the countries with at least one BSL-3 laboratory lacked oversight or regulation of dual-use research of concern.

Dual-use research refers to experiments that can be used for good (e.g., alleged drug development) but also for harm (e.g., creating a bioweapon).

The Journal of Public Health study aimed to investigate the worldwide distribution of BSL-3 and BSL-4 laboratories.

Alarmingly, it found that:

“No international organization has a comprehensive register or global oversight of Biosafety Level 3 (BSL-3)/BSL-4 laboratories. Different countries use different standards for designation of pathogens and laboratories.”

“More than 90% of the countries with at least one BSL3 laboratory have no oversight/regulations regarding dual-use research.”

BSL-4 laboratories handle the most dangerous and exotic pathogens that often cause fatal diseases with no available vaccines or treatments, such as Ebola and Marburg viruses.

Taken together, the proliferation of BSL-3 and BSL-4 labs around the world raises national security, informed consent, and conflict of interest concerns.

• They raise informed consent concerns because citizens are often unknowingly and/or unwillingly exposed to risks from nearby labs or experimental pathogen releases conducted without public awareness or approval.

• They raise conflict of interest concerns because many of these labs are funded by entities that profit from the development of pathogens and drugs that target those pathogens, meaning they benefit financially from an accidental or intentional lab leak-caused outbreak.

Even former NIAID Director Anthony Fauci has admitted in print that the greatest biosecurity threat regarding dangerous pathogen research is laboratory “insiders who have direct access” to the pathogens or “outsiders who collaborate with or subvert insiders.”

Given the mounting evidence of accidents, secrecy, and conflicts of interest, the continued operation of these bioweapons labs poses an unacceptable threat to humanity’s safety.

The only responsible course is to shut down all BSL-4 facilities worldwide and impose a global moratorium on high-risk pathogen experiments in order to prevent further catastrophe.

But governments all over the world are doing the opposite.

The Journal of Public Health authors warn in their conclusion:

“The number of BSL-3 and BSL-4 laboratories is continually increasing, and many do not have adequate biosafety guidelines.”
