Acute respiratory infections surveillance system evaluation, Mozambique, June-December, 2021

Background: COVID-19 is a public health emergency with a huge morbidity and mortality impact on the population, and rapid diagnostic testing is essential for controlling the disease. The study evaluated the surveillance system for acute respiratory infections in sentinel posts, Mozambique, from 01 June to 31 December 2021. Methods: We evaluated the surveillance system using the CDC’s Public Health Surveillance Guidelines. Representativeness, acceptability, data quality and timeliness were assessed in 30 sentinel posts in ten provinces of Mozambique, with the exception of Maputo City. The data were analyzed and presented as proportions in text, graphs and tables. Results: The surveillance system captured a large number of suspected cases, totaling 21,238 across 10 provinces. The highest number of suspected cases was registered in females 55% (11,668/21,238) and the 15-49 age group 43% (9,082/21,238). The months with the highest number of cases were November 25% (5,245/21,238) and August 18% (3,885/21,238). Of the 793 forms identified, 76% had a closed result with the rapid antigen diagnostic test, implying unacceptability. The completeness rate for age was 93%, COVID-19 vaccination status was 52%, and test results was 76%; with an overall completeness rate of 74% denoting regular data quality. Of the 42 interviewees, 69% (29/42) reported that the notification and availability of data in the Laboratory Information Management System took less than 24 hours. Conclusion: The system was representative with regular data quality but lacked acceptability and timeliness. There is a need for training and sensitization of professionals in properly completing forms and logbooks.
