Biosafety Level 4 (BSL-4)
As the highest level of biological safety, BSL-4 labs work with highly dangerous and exotic microbes, such as the Ebola and Marburg viruses..
Avoid contact with items that may have come in contact with an infected person's blood or body fluids (such as clothes, bedding, needles, and medical equipment).
Avoid funeral or burial practices that involve touching the body of someone who is suspected or confirmed to have had Ebola disease..
Recommendations for laboratory testing by staff: Any person testing specimens from a patient with a suspected case of Ebola virus disease should wear gloves, water-resistant gowns, full face shield or goggles, and masks to cover all of nose and mouth, and as an added precaution use a certified class II Biosafety .
Specimens from patients under investigation for Ebola disease should only be handled, moved and transported in a certified biological safety cabinet (BSC) or other primary containment device, and never on an open bench.Feb 14, 2023.
A laboratory that provides the top level of security (BSL-4 laboratory) allows scientists to handle pathogens of the highest Risk Group 4, such as Ebola, Lassa and Nipah viruses..
The microbes in a BSL-4 lab are dangerous and exotic, posing a high risk of aerosol-transmitted infections.
Infections caused by these microbes are frequently fatal and without treatment or vaccines.
Two examples of microbes worked with in a BSL-4 laboratory include Ebola and Marburg viruses..
Ebola virus (EBOV) is a highly contagious lethal pathogen.
As a biosafety level 4 (BSL-4) agent, however, EBOV is restricted to costly BSL-4 laboratories for experimentation, thus significantly impeding the evaluation of EBOV vaccines and drugs..

Two examples of microbes worked with in a BSL-4 laboratory include Ebola and Marburg viruses..
The filoviruses Ebola and Marburg are zoonotic agents that are classified as both biosafety level 4 and category A list pathogens.
These viruses are pathogenic in humans and cause isolated infections or epidemics of viral hemorrhagic fever, mainly in Central Africa..

As the highest level of biological safety, BSL-4 labs work with highly dangerous and exotic microbes, such as the Ebola and Marburg viruses.
Infections caused by these types of microbes are often fatal and come without treatment or vaccines..

Controlled activities with ebolaviruses require a Human Pathogens and Toxins Licence issued by the Public Health Agency of Canada and additional security requirements, such as:
Infection control strategies may have to be modified to include:
Importantly, handling of samples from individuals with suspected or confirmed Ebola, or research samples of Ebola virus, should always be done in containment (e.g., biosafety cabinets, BSCs) to protect workers and to prevent contamination of surfaces outside the BSC.
There is no identifiable risk of infection with Ebola in the Broad laboratories.
When samples are brought to the Broad, they consist of purified RNA only without the viral protein machinery necessary for infection, eliminating the hazard.
By itself, viral RNA from Ebola and other hemorrhagic fever viruses is non-infectious.
