DISCUSSION ON INFECTION IN THE DORMITORY: Joint Discussion No. 7.

(1) An attempt is made to show that infection in the dormitory is of paramount importance in most of the epidemics which occur in boarding schools and residential institutions. (2) The conditions in dormitories which favour a rapid and easy transmission of infection are: proximity of beds, deficient and not "cross" ventilation, insufficient floor space, "dead" space in ceiling, and "dead" corners. More than two rows of beds are to be deprecated. (3) The occurrence of epidemic tonsillitis or of serious complications of measles and influenza, and, bacteriologically, the presence of high carrier rates of haemolytic streptococci, may indicate the presence of such conditions in dormitories. (4) The minima suggested by the Board of Education (a) for dormitories and (b) for sanatorium wards or sick rooms are important for the prevention of the spread of infection.
