An Adenovirus Outbreak Associated with a Swimming Facility

Adenovirus is a double-stranded DNA virus that infects hosts across a broad spectrum of vertebrates [1]. Since its first isolation from human adenoid tissue and named for the tissue of origin in 1953, there have been more than 50 genotypes identified worldwide [2,3]. Adenovirus infection causes a variety of diseases with some genotype predisposition, including conjunctivitis, gastroenteritis, respiratory tract infection, and cystitis [4,5]. The clinical presentation ranges from mild self-limited illness to fatal infection [6]. A primary adenovirus infection may convey genotypespecific lifelong immunity to the human host [7].
