HUMAN HYDATID DISEASE IN NORTHERN KENYA
Hydatid disease or echinococcosis is a parasitic disease. Dogs or other carnivores are hosts for the adult tapeworm. These data are counts of human Hydatid disease in northern Kenya.
These data were abstracted from medical clinic records by Dr. P.B. Gathura, University of Nairobi. Each person was classified by sex and age. In the summary of medical records ages were classified in fifteen, five year intervals: 0-4 years, 5-9 years, ..., 64-69, and >69.
An analysis of the pattern of hydatid incidence is important in helping to both identify and support measures to combat potential risk factors for human infection.

Anomaly in the data
There is a very big difference in the average cyst per person between 0-4 years and
those between 5-9 years, this is unlike the other classes where the differences are not
so drastic.
The difference between the average cyst per gender 0 and 1 is consistent apart from the
ages 0-4 which the difference is extreme and thus suspect. It can be concluded that the
measures on the age group 0-4 years might have had errors.
