Table 2 Frequency of single and multiple infections. Non-acute specimens were collected at the start (R0) or end (RF) of the training period. Acute samples were collected from individuals who developed an acute upper respiratory tract infection during follow-up. Percentages indicate proportion of specimens in which no microbe, a single, or multiple microbes were detected
