What is Baltimore classification?

Baltimore classification categorizes viruses 7 groups based on their genome type. All viruses in a class behave in a similar fashion, making it easier for scientists to carry out further research. 

These are the seven classes of viruses in the Baltimore Classification System: 

Class I: Includes double-stranded DNA (dsDNA) viruses such as Adenoviruses, Poxviruses, and Herpesviruses

Class II: Includes single-stranded DNA (ssDNA) viruses such as Parvoviruses

Class III: Includes double-stranded RNA (dsRNA) viruses such as Reoviruses

Class IV: Includes single-stranded RNA (ssRNA) viruses such as Picornaviruses, Togaviruses

Class V: Includes single-stranded RNA (ssRNA) viruses such as Rhabdoviruses and Orthomyxoviruses 

Class VI: Includes positive-sense ssRNA reverse transcriptase viruses such as Retroviruses

Class VII: Includes double-stranded DNA (dsDNA) reverse transcriptase viruses such as Hepadnaviruses
