Abstract : Surveillance studies to determine the etiologic agents of acute respiratory disease (ARD) in basic combat trainees (BCTs) were conducted during fy '72. A total of 7,296 ARD hospitalized trainees at 8 training forts, were included in these studies. Viral isolations and serological studies indicated 42.4% of ARD hospitalizations were caused by Adenoviruses, 6.2% by influenza A and B, Mycoplasma and polio, and 51.6% by agents that were not determined. Efficacy evaluations of a 1971-72 lot of type 7 adenovirus vaccine which was administered at the 8 BCT forts during the upper-respiratory-disease season indicated this vaccine was not effective in preventing adenovirus 7 disease. Laboratory titrations of virus in the vaccine pills indicated a level below that recommended for an effective pill. A newly standardized bivalent influenza vaccine (A2/Ai chi/68; B/mass/66) was administered during the fiscal year. However, most of the 8 BCT forts experienced considerable influenza, 111 flu A and 47 flu B total infections. It is envisioned that with continued use of adenovirus 4 and 7 vaccines, and decline of these viruses with continued use of adenovirus 4 and 7 vaccines, and decline of these viruses as a cause of ARD, the unknown agents will occupy a larger area of ARD cause. Rhinoviruses probably occupy a portion of this undetermined group. (Author)
