This study was carried out on 1998 workers of Esco Spinning and Weaving Company at Shoubra El-Kaliubia Governorate during one year (January 1986 - December 1986) to study the impact of parasitic diseases on productivity.
The results showed that most examined workers were males, married, living in rural areas with low level of education. The age group 30-39 years showed the highest prevalence of parasitic diseases (76.5%), the lowest mean number of working days per month (23.4 + 2.5 days) and lowest mean payment by production per hour (0.078 + 1.02 Egyptian pounds).
Schistosoma infections (haematobioum and mansoni), Ancylostoma duodenale and mixed infections affected the productivity of workers in the form of lowering the mean number of working days per month, the mean payments by produ tion per hour and the mean incentives per month whereas other infections did not interfere.
