Abstract
Between August 15 and September 15 1980, an outbreak of infections due to adenovirus type 7b occurred at Children's Hospital and Health Center t San Diego, California. During that timet four of six patients infected with adenovirus type 7b died. All patients with hospital-acquired disease had underlying respiratory compromise. Cultures, adenoviral serology tests, and histories were obtained from 383 (93%) of the 410 hospital employees. All 11 people from whom adenovirus type 7 was cultured were nurses working in a unit with an infected patient. Seven other employees with negative cultures had a fourfold or greater rise in their adenoviral complement fixation titers. This outbreak demonstrates that adenovirus type 7 infections are capable of causing serious and potentially fatal disease in hospitalized patients and suggests that individuals with underlying respiratory diseases are especially at risk.
