variola minor virus
Definition
Noun: A strain of the variola virus that causes variola minor, a milder form of smallpox characterized by a less severe rash and a significantly lower mortality rate (approximately 1%) compared to variola major.
Examples of Usage
- The variola minor virus was responsible for the less deadly form of the disease, which helped survivors develop immunity against the more lethal strain.
- Scientists studied the genetic differences between the variola minor virus and variola major virus to understand their varying levels of virulence.
- Due to its lower fatality rate, outbreaks caused by the variola minor virus were often less devastating to populations.
Advanced Usage
- In epidemiological history, the co-circulation of variola minor virus with its more virulent counterpart complicated disease surveillance and control efforts.
- The term is used in virology to specifically denote the subtype of the variola virus, distinguishing it from other orthopoxviruses.
Variants and Related Words
- Variola minor (n): The disease caused by the variola minor virus.
- Alastrim (n): Another name for the variola minor virus or the disease it causes.
- Variola virus (n): The virus species that includes both variola major and variola minor viruses.
- Smallpox virus (n): A common term for the variola virus.
Synonyms
- Alastrim virus
Notes on Meaning
This term refers specifically to the biological agent (the virus), not the disease itself. The key distinction from 'variola major virus' lies in its attenuated pathogenicity and the clinical outcome of the infection it causes.
Noun
-
a type of smallpox virus that has a fatality rate of about 1 percent
