[Annotation] Case report(s) / study subset [Description] 
Case reports of complete genomic sequences that were submitted to GenBank because of some unusual characteristic unrelated to sequence diversity (e.g. a strain with unique tropism characteristics, or a strain associated with an epidemiologic cluster). A subset of sequences obtained from a large study is not added, if the subset is highly unrepresentative of the larger study.
