Background:- Public health surveillance (PHS) is the continuing organized gathering, investigation, elucidation, and well-timed distribution of health-related information for activities and program evaluation. Conducting a surveillance system evaluation is crucial for monitoring the efficacy and effectiveness of intervention programs in health care systems. This study aimed to Evaluate the Trends of Malaria in the hotspot and Ivermectin mass-drug administration Zone of Amhara Regional State, Ethiopia, 2020.
Methods: - A descriptive prevalence study design was used to evaluate the surveillance system of the Awi zone selected woreda. 25 study sources were incorporated in the survey (5 District Health Offices (5HOs), 10 Health Centers (10HCs), and 10 Health Posts (10 HPs). Purposive sampling techniques were utilized. Data were obtained by communicable diseases control the standard format of systematic evaluation of four surveillance units from January to August 2020 through observation, document review, and interviewing surveillance officers and focal persons using a semi-structured Survey.
Results: - Average report fullness and aptness were 97.9% and 96% respectively. The average annual malaria incidence rate was a decline from the year 2015 to 2019 with an average reduction rate of 5.5% and the average annual parasitic incidence rate was 52 (22-199). In 2019/2020, 43131 Malaria cases were reported in the zone. Supervisions were made as integrated supportive supervision in the last six months. However, there was no program specific supportive supervision of public health emergency management. Data analysis was not routinely practiced in both visited districts and was not used for decision making.
Conclusions: This result revealed that the malaria incidence rate showed a remarkable decline. However, the annual parasitic incidence rate remains constant. This indicates that ivermectin did not affect malaria elimination. The structure of the surveillance information transfer as of Kebel to Zone was well organized. However, coordination and supervision of the surveillanc activities were not frequent. From those supervised health facilities, most of them are not receiving feedback. There was no budget line, written feedback, epidemic and preparedness, and a response plan regular based on supportive supervision at all visited health facilities. Depending on this, we recommend that districts and sub-city health offices should conduct regular surveillance data analysis, perform supportive supervision, avail budgets and mitigate resource constraints and improve data quality on the job training and supportive supervision. Further laboratory investigations should be done to investigate the effect of ivermectin on the parasites under laboratory conditions.
