Adenovirus infections

The infections caused by adenovirus are acute febrile disorders characterized by inflammation of the respiratory and ocular mucous membranes, followed by follicular hyperplasia of sub mucosal and regional lymphoid tissue. Adenovirus is also present in the intestinal tract causing pronounced or latent infections in the mesenteric lymph nodes, tonsil and the adenoids. There are over twenty serotypes of adenoviruses.

Signs and symptoms of the infections are usually sudden. They include malaise, fever, and sore throat. There is also noticeable enlargement of regional lymph nodes; sometimes pharyngeal lymphoid hypertrophy is present. Rarely there is secondary Pneumonitis. Other diseases caused by adenoviruses are Acute Respiratory Disease (ARD), Epidemic kerato conjunctivitis (EKC), acute respiratory illness (AFRI), and pharyngeal conjunctiva fever (PCF), and virus pneumonia of infants.
