[Morbidity studies in children's nurseries]

In 1986-1988 the indices of absence morbidity taken from monthly reports of crèches were registered in 8 crèches of Dresden and were compared with the real total morbidity, which had been registered with help of a symptom catalogue for one year. The total morbidity amounted to more than the double of absence morbidity, the total of the illness days per case amounted to 8.42 days and the days of absence morbidity amounted 7.3. The description of infection groups with help of quarters (according to Adam) on the basis of the registered total morbidity showed differences with regard to: average illness period per case (children susceptible to infections: 9.33 d; children robust to infections: 6.82 d) and average recurrence period (children susceptible to infections: 15.7 d; children robust to infections: 78.2 d). Probable causes of susceptibility to infections and conclusions hence to be drawn.
