Introduction

Diarrhoea diseases remain a major public health threat with nearly 1.7 billion cases annually worldwide occurring in all age groups. In Ghana diarrhoea kills about 14,000 children under five years annually. We therefore analysed data to determine the morbidity pattern of diarrhoea diseases in the Central Region of Ghana.

Methods

Health facility morbidity data was reviewed from 2008-2012. Monthly data on diarrhoeal diseases were extracted from District Health Information Management System database by sex, age group and districts. Data for bloody diarrhoea were extracted from monthly surveillance report forms. Data was analysed descriptively and expressed as frequencies and proportionate morbidity rates (pmr). Aberrations were determined using C2 threshold.

Results

The total cases of all morbidity from 2008 to 2012 were 7,642,431. Diarrhoea diseases formed 4% (306854/7642431) of total morbidity. Children under one year (pmr= 8.4%) and males (pmr= 4.4%) were the most affected. Bloody diarrhea formed 2.2% (6835/306854) of diarrhoea cases with 0.7 %(45/6835) laboratory confirmed. Diarrhoea cases peaked from January to March throughout the study period with highest frequency 9.3% (28511/306854) in June. The mean monthly distribution of diarrhoea cases was 25571.17±1389.91. Poorest districts had significantly lower odds of getting bloody diarrhoea than non-poorest districts OR = 0.73 (95%CI = 0.70-0.77).

Conclusion

Diarrhoea characterized 4% of total morbidity presenting at health facilities in the region from 2008 to 2012. The diarrhoea morbidity rate decreased with increased age. Diarrhoea was higher among non poorest districts. The rate was highest in the month of June over the five year period. Bloody diarrhoea cases were mostly untested. We recommended that stool samples should be taken for laboratory testing for bloody diarrhoea cases.
