RSV1

RSV1 is a designation that appears in several fields and does not have a single, universal definition. In virology and infectious disease literature, RSV most commonly refers to respiratory syncytial virus, a negative-sense RNA virus in the family Pneumoviridae that causes respiratory disease, particularly in young children and older adults. The label RSV1 is not an official taxonomic term; when used, it typically indicates the first isolate, clone, or sample identified within a particular study or dataset, and may be superseded by accession numbers or full strain names in databases.

In other contexts, such as plant virology, RSV is used as an abbreviation for Rice stripe virus, a plant pathogen transmitted by planthoppers. In such cases, RSV1 likewise would denote a specific isolate or gene label used within a study, rather than a standardized designation.

In data resources and software projects, RSV1 may appear as a version code, model identifier, or sample label. The precise meaning is entirely dependent on the source.

For clarification, it is best to consult the specific publication, database entry, or dataset that uses the term RSV1. See also RSV (disambiguation), Rice stripe virus, and respiratory syncytial virus.
