Safety and Laboratory Supplies for Protection Against Zika

Biological Safety Levels

Zika and dengue viruses are classified as Biosafety Level (BSL) 2 pathogens. BSL-2, building upon BSL-1, is suitable for work involving agents that pose moderate hazards to personnel and the environment.

It differs from BSL-1 in three ways:

1. Laboratory personnel have specific training in handling pathogenic agents and are supervised by scientists competent in handling infectious agents and associated procedures.
2. Access to the laboratory is restricted when work is being conducted.
3. All procedures in which infectious aerosols or splashes may be created are conducted in BSCs or other physical containment equipment.
