BackgroundGlobally, non-attendance for immunization appointments remains a challenge to healthcare providers. A review of the 2011 immunization coverage for Kadoma City, Zimbabwe was 74% for Oral Polio Vaccine (OPV), Pneumococcal and Pentavalent antigens. The immunization coverage was less than 90%, which is the target for Kadoma City. Adoption of short message services (SMS) reminders has been shown to enhance attendance in some medical settings. The study was conducted to determine the effectiveness of SMS reminders on immunization programme for Kadoma City.MethodsA randomized controlled trial was conducted at Kadoma City clinics in Zimbabwe. Women who delivered and were residents of Kadoma City were recruited into the study. In the intervention group, SMS reminders were sent at 6, 10 and 14 weeks in addition to routine health education. In the non-intervention no SMS reminders were used, however routine health education was offered. Data were collected using interviewer administered questionnaire. Data were analyzed using Epi Info 7™, where frequencies, means, risk ratios and risk differences were generated.ResultsA total of 304 participants were recruited, 152 for the intervention group and 152 for the non-intervention group. The immunization coverage at 6 weeks was 97% in the intervention group and 82% in the non-intervention group (p < 0.001). At 14 weeks immunization coverage was 95% for intervention and 75% for non-intervention group (p < 0.001). Those who did not delay receiving immunization at 14 weeks was 82% for the intervention and 8% for non-intervention group. Median delay for intervention was 0 days (Q1 = 0; Q3 = 0) and 10 days (Q1 = 6; Q3 = 17) for non-intervention group. The risk difference (RD) for those who received SMS reminders than those in the non intervention group was 16.3% (95% CI: 12.5-28.0) at 14 weeks.ConclusionImmunization coverage in the intervention group was significantly higher than in non-intervention group. Overall increase in immunization coverage can be attributed to use of SMS.Trial registrationISRCTN70918594. Registration Date: 28 August 2014.

IntroductionThe Notifiable disease surveillance system (NDSS) was established in Zimbabwe through the Public Health Act. Between January and August 2011, 14 dog bites were treated at Kadoma Hospital. Eighty-six doses of anti-rabies vaccine were dispensed. One suspected rabies case was reported, without epidemiological investigations. The discrepancy may imply under reporting of Notifiable Diseases. The study was conducted to evaluate the NDSS in Sanyati district.MethodsA descriptive cross sectional study was conducted. Healthcare workers in selected health facilities in urban, rural, and private and public sector were interviewed using questionnaires. Checklists were used to assess resource availability and guide records review of notification forms. Epi InfoTM was used to generate frequencies, proportions and Chi Square tests at 5% level.ResultsWe recruited 69 participants, from 16 facilities. Twenty six percent recalled at least 9 Notifiable diseases, 72% correctly mentioned the T1 form for notification, 39% correctly mentioned the forms completed in triplicate and 20% knew it was a legal requirement to notify. Ninety six percent of respondents indicated willingness to participate, whilst 41% had ever received feedback. Three out of 16 health facilities had T1 forms.ConclusionNDSS is useful, acceptable, simple, and sensitive. NDSS is threatened by lack of T1 forms, poor feedback and knowledge of health workers on NDSS. T1 forms and guidelines for completing the forms were distributed to all health facilities, public and private sector. On the job training of health workers through tutorials, supervision and feedback was conducted.

BackgroundKadoma City experienced an increase in watery diarrhoea from 27 cases during week beginning 5th September, to 107 cases during week beginning 26th September 2011. The weekly diarrhoea cases crossed the threshold action line during week beginning 5th September at the children’s clinic in Rimuka Township, and the remaining four clinics reported cases crossing threshold action lines between week beginning 12th September and week beginning 26th September. Eighty-two percent of the cases were children less than 5 years old. We conducted a case controlstudy to determine risk factorsfor contracting watery diarrhoea in children less than 5 years in Kadoma City.MethodsAn unmatched 1:1 case control study was conducted in Ngezi and Rimuka townships in Kadoma City, Zimbabwe. A case was a child less than 5 years old, who developed acute watery diarrhoea between 5th September and 1st October 2011. A control was a child less than 5 years old who stayed in the same township and did not suffer from diarrhoea. A structured questionnaire was administered to caregivers of cases and controls.Laboratory water quality tests and stool test results were reviewed.Epi Info™ statistical software was used to analyse data.ResultsA total of 109 cases and 109 controls were enrolled. Independent protective factors were: having been exclusively breastfed for six months [AOR = 0.44; 95% CI (0.24-0.82)]; using municipal water [AOR = 0.38; 95% CI (0.18-0.80)]; using aqua tablets, [AOR = 0.49; 95% CI (0.26–0.94)] and; storing water in closed containers, [AOR = 0.24; 95% CI (0.07–0.0.83). The only independent risk factor for contracting watery diarrhoea was hand washing in a single bowl, [AOR = 2.89; 95% CI (1.33–6.28)]. Salmonella, Shigella, Rotavirus, and Enteropathogenic Escherichia coli were isolated in the stool specimens. None of the 33 municipal water samples tested showed contamination with Escherichia coli, whilst 23 of 44 (52%) shallow well water samples and 3 of 15(20%) borehole water samples tested were positive for Escherichia coli.ConclusionsThe outbreak resulted from inadequate clean water and use of contaminated water. Evidence from this study was used to guide public health response to the outbreak.

Abstract. In 2008-2009, Zimbabwe experienced an unprecedented cholera outbreak with more than 4,000 deaths. More than 60% of deaths occurred at the community level. We conducted descriptive and case-control studies to describe community deaths. Cases were in cholera patients who died outside health facilities. Two surviving cholera patients were matched by age, time of symptom onset, and location to each case-patient. Proxies completed questionnaires regarding mortality risk factors. Cholera awareness and importance of rehydration was high but availability of oral rehydration salts was low. A total of 55 case-patients were matched to 110 controls. The odds of death were higher among males (adjusted odd ratio [AOR] = 5.00, 95% confidence interval [CI] = 1.54-14.30) and persons with larger household sizes (AOR = 1.21, 95% CI = 1.00-1.46). Receiving home-based rehydration (AOR = 0.21, 95% CI = 0.06-0.71) and visiting cholera treatment centers (CTCs) (AOR = 0.07, 95% CI = 0.02-0.23) were protective. Receiving cholera information was associated with home-based rehydration and visiting CTCs. When we compared cases and controls who did not go to CTCs, males were still at increased odds of death (AOR = 5.00, 95% CI = 1.56-16.10) and receiving home-based rehydration (AOR = 0.14, 95% CI = 0.04-0.53) and being married (AOR = 0.26, 95% CI = 0.08-0.83) were protective. Inability to receive home-based rehydration or visit CTCs was associated with mortality. Community education must reinforce the importance of prompt rehydration and CTC referral.

We conducted a matched case-control study for age, sex, and village. Setting: Arural community in Musadzi area of GokweNorth district. Subjects: We interviewed 35 cases and 35 controls. A case was defined as any resident/visitor o f Musadzi, diagnosed with anthrax between 9 September and 10 November 2004. A control was any resident who had not been diagnosed with anthrax and had no lesions suggestive o f anthrax on day o f the interview. Main Outcome Measures: Behaviour factors associated with contracting anthrax. Results: In September 2004, cattle were reported to be dying in Musadzi area. Bacillus anthracis was positively identified in a blood smear from some o f the carcasses. The attack rate among humans was 5%. Risk factors associated with contracting anthrax were: skinning o f animals that had died from unknown causes AOR=3.8 (95% 0 :1.3-10.7); preparation o f the meat for cooking (AOR-3.1 (95% 0:1.16-8-4); preparation o f the meat for drying AOR=2.7 (95% Cl: 1.0081-7.4); belonging to a religious or ethnic sect that allow handling o f meat from animals that had died from unknown causes (AOR=5.2 (95% Cl: 1.8-14.8). Conclusion: The human anthrax outbreak was secondary to an anthrax epizootic occurring in cattle. The Ministry of Health activated the local zoonotic committee, carried out anthrax awareness campaigns, supervised the destruction o f carcasses, disinfected potentially contaminated sites and introduced a participatory health education tool on anthrax. The veterinary department quarantined and vaccinated cattle.
