Insights
Diarrhoea diseases are a significant public health issue in Ghana, particularly affecting children under one year old. The study found that diarrhoea accounted for 4% of all illnesses and was more prevalent in non-poorest districts.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Diarrhoea diseases represent a major global public health challenge, causing nearly 1.7 billion cases annually.
- In Ghana, diarrhoea is a leading cause of mortality in children under five, with approximately 14,000 deaths each year.
Purpose of the Study:
- To analyze the morbidity patterns of diarrhoea diseases in Ghana's Central Region.
- To identify demographic and socioeconomic factors associated with diarrhoea incidence.
Main Methods:
- Retrospective review of health facility morbidity data from 2008 to 2012.
- Extraction of monthly diarrhoea data by sex, age, and district from the District Health Information Management System.
- Analysis of bloody diarrhoea data from surveillance reports using descriptive statistics and C2 threshold for aberrations.
Main Results:
- Diarrhoea diseases constituted 4% of total morbidity (306,854 cases out of 7,642,431).
- Infants under one year (8.4% proportionate morbidity rate) and males (4.4% pmr) were most affected.
- Bloody diarrhoea represented 2.2% of cases, with low laboratory confirmation rates (0.7%). Cases peaked in June, and were higher in non-poorest districts.
Conclusions:
- Diarrhoea significantly contributed to the overall disease burden in the Central Region of Ghana.
- Morbidity rates decreased with age, and were higher in non-poorest districts.
- The high proportion of untested bloody diarrhoea cases necessitates improved diagnostic practices, including stool sample testing.
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.
