What does adenovirus mean?
An adenovirus is any member of a family of DNA viruses (Adenoviridae) that infect humans and many animals. In people, adenoviruses most often attack the respiratory tract, producing symptoms that resemble the common cold — sore throat, cough, congestion, and fever — but they can also cause conjunctivitis (pinkeye), croup, bronchitis, pneumonia, and stomach or intestinal illness. Because these infections spread readily through close contact, contaminated surfaces, water, and respiratory droplets, adenoviruses are a familiar culprit in outbreaks at schools, military barracks, swimming pools, and daycare centers. The word is primarily used in medical and scientific writing rather than casual conversation, though it appears in news reports about local outbreaks. Beyond its role as a pathogen, the adenovirus has become a valuable tool in biotechnology: weakened or modified adenoviruses serve as vectors to deliver genetic material in gene therapy research and in some vaccines. Its plural is adenoviruses.
nounAny of a group of DNA viruses that infect humans and other animals, commonly causing respiratory illnesses such as colds, sore throats, bronchitis, and pneumonia, as well as conjunctivitis and gastroenteritis.
- Any of a group of medium-sized, non-enveloped DNA viruses of the family Adenoviridae that infect humans and animals, typically causing respiratory, ocular, or gastrointestinal disease.
"The outbreak of pink eye at the school was traced to an adenovirus spreading through shared towels."
"Military recruits are routinely vaccinated against adenovirus because crowded barracks make outbreaks likely."
"Researchers use a modified adenovirus as a vector to deliver genetic material into cells during gene therapy trials."
The standard plural adds -es; it is used when referring to multiple strains or types of the virus.
"Several distinct adenoviruses were circulating in the community that winter."
Adenoviruses were first isolated from human adenoids — the tonsil-like tissue at the back of the nose — which is exactly how they got their name.

Etymology of adenovirus
The word adenovirus was coined in the mid-1950s, shortly after the viruses were first isolated from human adenoids — lymphatic tissue in the nasopharynx removed during tonsil surgery. It combines the Greek-derived element adeno- (from Greek 'adēn', meaning gland) with the New Latin 'virus'. The same Greek root gives English words such as adenoid, adenoma, and adenitis, all referring to glands or gland-like tissue.
How adenovirus is actually used
Adenovirus is a technical term used chiefly in medical, scientific, and public-health contexts; in everyday speech people usually name the illness (a cold, pinkeye) rather than the virus. The plural is adenoviruses. It is frequently encountered in news coverage of outbreaks and in discussions of viral vectors for vaccines and gene therapy.
Easily confused with adenovirus
Influenza is caused by influenza viruses (RNA viruses), whereas adenoviruses are DNA viruses that can cause similar respiratory symptoms but are a distinct family of pathogens.
Rhinoviruses are the most common cause of the common cold, while adenoviruses are a separate virus family that can also cause colds but more often produce fever, conjunctivitis, or gastrointestinal illness.
