Human adenovirus infections are caused by a group of DNA viruses that commonly infect the respiratory and gastrointestinal tracts, as well as the eyes and the urinary tract. Antonyms for this medical term would refer to conditions that are not caused by these viruses, or to states of health that are opposite to those associated with adenoviral infections. For example, antonyms for the symptoms of adenovirus infections such as fever, cough, runny nose, diarrhea, or conjunctivitis may include a normal body temperature, absence of respiratory or digestive discomfort, and clear eyes. Similarly, the absence of viral shedding, immunity to adenoviruses, or effective vaccines could be antonyms for the transmission and prevention of these infections.
