ABSTRACT
OBJECTIVE: On 24th October 2016, the Central Regional Health Directorate received report of a suspected cholera outbreak in the Cape Coast Metropolis (CCM). We investigated to confirm the diagnosis, identify risk factors and implement control measures. DESIGN: We used a descriptive study followed by 1:2 unmatched case-control study. DATA SOURCE: We reviewed medical records, conducted active case search and contact tracing, interviewed case-patients and their contacts and conducted environmental assessment. Case-patients' stool samples were tested with point of care test kits (SD Bioline Cholera Ag 01/0139) and sent to the Cape Coast Teaching Hospital Laboratory for confirmation. MAIN OUTCOMES: Cause of outbreak, risk factors associated with spread of outbreak. RESULTS: Vibrio cholerae serotype Ogawa caused the outbreak. There was no mortality. Of 704 case-patients, 371(52.7%) were males and 55(7.8%) were aged under-five years. The median age was 23 years (interquartile range: 16-32 years). About a third 248(35.2%) of the case patients were aged 15-24 years. The University of Cape Coast subdistrict was the epicenter with 341(48.44%) cases. Compared to controls, cholera case-patients were more likely to have visited Cholera Treatment Centers (CTC) (aOR=12.1, 95%CI: 1.5-101.3), drank pipe-borne water (aOR=11.7, 95%CI: 3.3-41.8), or drank street-vended sachet water (aOR=11.0, 95%CI: 3.7-32.9). Open defecation and broken sewage pipes were observed in the epicenter. CONCLUSION: Vibrio cholerae serotype Ogawa caused the CCM cholera outbreak mostly affecting the youth. Visiting CTC was a major risk factor. Prompt case-management, contact tracing, health education, restricting access to CTC and implementing water sanitation and hygiene activities helped in the control. FUNDING: This work was supported by Ghana Field Epidemiology and Laboratory Training Program (GFELTP), University of Ghana.

BACKGROUND: Loss of human immunodeficiency virus (HIV)-positive patients to follow-up increases HIV-related morbidity and mortality. This study identified the factors associated with loss to follow-up (LTFU) in an urban health facility in Ghana. METHODS: A 12-y retrospective study was conducted using routinely collected data from the National Acquired Immune Deficiency Syndrome (AIDS) Control Programme (NACP) on persons living with HIV/AIDS (PLWHA) who initiated antiretroviral therapy (ART) from 2006 to 2017 at the Greater Accra Regional Hospital. Convenience sampling was used to select the study area. All gathered data were exported to Stata 14 statistical software for analysis. RESULTS: A total of 4330 PLWHA initiated ART between January 2006 and December 2017. Of these, 1166 (26.9%) were lost to follow-up over the 12-y period. The factors associated with LTFU included being a Muslim (adjusted hazard ratio [aHR] 1.31 [95% confidence interval {CI} 1.05 to 1.65]), having CD4 <250 cells/ml (aHR 1.45 [95% CI 1.21 to 1.76]) and completing adherence counselling (aHR 1.58 [95% CI 1.31 to 1.92]). Having other sources of health care funding and disclosure of one's disease status were found to be protective (aHR 0.74 [95% CI 0.58 to 0.94] and 0.80 [95% CI 0.65 to 0.98], respectively). CONCLUSIONS: Some of the determinants of LTFU in the hospital are comparable to those found in other parts of Africa and could be addressed using existing interventions.
