influenza and the rates of hospitalization for respiratory disease among infants and young children.young children may be at increased risk for serious complications from influenzavirus infection. however, in population-based studies it has been difficult to separate the effects of influenzavirus from those of respiratory syncytial virus. respiratory syncytial virus often circulates with influenzaviruses and is the most frequent cause of hospitalization for lower respiratory tract infections in infants and young children. we studied the rates of hospitalization for acute respiratory-disease am ...200010648764

long-term epidemiology of infections with mycoplasma pneumoniae.pneumonia due to mycoplasma pneumoniae was monitored in a large prepaid medical-care group in seattle, washington, between 1963 and 1975. the disease was diagnosed by isolation of m. pneumoniae and/or significant rises in titer of complement-fixing (antilipid) antibody in paired sera. infection was endemic without significant seasonal fluctuations. two epidemics occurred: the first peaked in january 1967, the second late in the summer of 1974. total rates of pneumonia infection in children incre ...1979448195
