From: Small but mighty: old and new parvoviruses of veterinary significance
Number of animal parvoviruses discovery by year. Graph showing the number of new ICTV-recognized non-human, vertebrate animal parvoviruses [20] discovered between 1958 and 2019. Viruses discovered since 2019 have not been consistently added to the ICTV taxonomy and are, thus, excluded. Note the marked increase in viral discovery in the last 20 years due to the use of metagenomics and high-throughput sequencing
