Q. Ebola virus is an example of a pathogen associated with which risk group?

A). Risk group-1

B). Risk group-2

C). Risk group-3

D). Risk group-4

Answer: Risk group-4

Explanation: The members of the genus Ebolavirus are considered to be Risk Group-4 (RG4) human pathogens and RG4 animal pathogens. Ebolavirus is also represented as a security-sensitive biological agent (SSBA).

Risk group-1

The microorganisms that do not cause infection in healthy adult humans are considered to be risk group-1 microbes.

Example: Some E. coli strains, Lactobacillus spp., some Bacillus spp., and Saccharomyces spp. (yeast).

Risk group-2

The organisms are responsible for the treatable or preventable diseases are classified as risk group-2 microbes.

Example: Herpes virus, Hepatitis A, B, C, D, and E viruses, All human papillomaviruses, Paramyxoviruses, Cladosporium bantianum, Streptococcus spp., Amycolata autotrophica, Yersinia enterocolitica, Salmonella spp., Neisseria gonorrhoeae, Mycobacterium spp, Staphylococcus aureus, Helicobacter pylori, Vibrio cholerae, etc.

Risk group-3

The organisms that cause more harm to humans are considered to be risk group-3 microbes. However, the treatment options and vaccines for these diseases may available.

Example: Coronaviruses, Arenaviruses, Semliki forest virus, Chikungunya virus, Pasteurella multocida, Yersinia pestis, Rickettsia spp., Brucella spp., Bartonella spp., Coccidioides immitis, Histoplasma spp., etc.

Risk group-4

The microbes that are responsible for the deadly diseases in humans are classified as risk group-4 human pathogens. The transmission rate of these microbes from one person to another is very high. No treatment options or vaccines are available for these diseases.

Example: Ebolavirus, Junin virus, Marburg virus, Machupo virus, Lassa virus, Bunyaviruses, Polyomavirus, Bovine papillomavirus, Feline leukemia virus, Gibbon leukemia virus, etc.
