As high-consequence pathogens can potentially infect subjects through airborne particles, aerobiology has been increasingly applied in pathogenesis research and medical countermeasure development. We present a detailed visual demonstration of aerobiology procedures during an aerosol challenge in nonhuman primates in an animal biosafety level 4 maximum containment environment.

Performing viral assays in a BSL-4 laboratory is more involved compared to work in a BSL-2 laboratory due to required additional safety precautions. Here, we present an overview of practices and procedures used inside a BSL-4 laboratory illustrating proper Class II biosafety cabinet usage, waste management/disposal, and sample removal.

Here, we present an overview of the preparation and animal handling procedures required to safely perform medical imaging in an animal biosafety level 4 laboratory. Computed tomography of a mock-infected guinea pig illustrates these procedures that may be used to evaluate the disease caused by a high consequence pathogen.
FAQs
Directional airflow is an engineering control that supports containment by managing how air moves within the laboratory. Used alongside controlled access and other safeguards, it helps reduce the chance that infectious material will spread beyond designated work areas. This layered design is especially important when studies involve agents capable of causing serious disease through inhalation.
Each safeguard addresses a different route of exposure or release. Engineering controls provide facility-level containment, personal protective equipment adds a barrier between researchers and infectious material, and validated decontamination procedures address contaminated surfaces, materials, or waste. Combining these measures creates layered protection rather than relying on a single control that could fail or be insufficient on its own.
Controlled access limits laboratory entry to activities and personnel appropriate for the work being performed. This principle helps reduce unnecessary exposure and supports accountability within the containment environment. In immunology and infection research, restricting access also helps preserve consistent experimental conditions while protecting people outside the work area from accidental contact with infectious agents.
Validation demonstrates that decontamination procedures are suitable for preventing infectious material from remaining in the laboratory environment. These procedures form part of the facility’s release-prevention strategy and complement airflow management, protective equipment, and access controls. Their importance extends beyond routine cleanup because effective decontamination helps maintain containment throughout experiments and when materials leave designated work areas.
The facility supports studies of pathogen biology, host immune responses, transmission, and therapeutic or vaccine candidates. Researchers can therefore examine both the infectious agent and the biological responses or interventions associated with it under controlled conditions. This combination makes the setting useful for connecting mechanistic infection studies with questions about prevention, diagnosis, and treatment.
Work in this setting allows investigators to study how pathogens interact with hosts while maintaining safeguards appropriate to high-risk infection research. Findings can clarify immune responses, inform evaluation of vaccine or therapeutic candidates, and improve understanding of transmission. The resulting evidence supports broader efforts to develop strategies for infectious disease prevention, diagnosis, and treatment.
