Early case detection and isolation of patients infected with highly infectious diseases through active case search (ACS) are important for early commencement of treatment and control of the disease within a population. This study aimed to assess the ACS of COVID-19 in healthcare facilities during the third wave of the pandemic in Ekiti State, Nigeria. This cross-sectional study was conducted in all healthcare facilities in Ekiti State. All cadres of local government primary healthcare workers were trained to carry out the ACS using semi-structured interviewer-administered questionnaire uploaded on android phone software open data kit (ODK). ACS was conducted between June and September (epidemiological week 23 to 36), 2021 and the collected data were analyzed using IBM SPSS version 23.0. P-value < 0.05 was taken as significant. The number of ACS visits for COVID-19 increases with epidemiological week progression, but the highest was in week 32 (9.9%). Cases of suspected COVID-19 in the healthcare facilities in the last one week were reported in more than half (58%) of the visits and 57.8% of those reported, documented between 1 - 4 cases. Also, out of those that were reported, 42% of them missed (not line listed) at least one suspected case of COVID-19. The private health facilities missed more cases of COVID-19 (54.3%) than other categories of health facilities (p < 0.001). The health educators and local government immunization officers (LIO) than other cadre of healthcare workers found most missed cases (57.1% and 51.4% respectively) in their visits (p < 0.001). The health educator as well as the LIO detected the highest proportion of missed suspected cases which shows that disease surveillance officers alone may not be adequate for ACS, there is a need to involve other local government team member.

Mpox disease is caused by a double-stranded DNA virus, genus Orthopoxvirus of the family Poxviridae. The incubation period is usually 6 to 13 days but can range from 5 to 21 days while symptoms and signs may persist for 2 to 5 weeks. Although, the clinical features are usually less severe when compared to the deadly smallpox, the disease can be fatal with case fatality rate between 1% and 10%. In Imo State, Nigeria, there has been a changing epidemiology of the disease in the last 6 years and the frequency and geographic distribution of cases have progressively increased. This study aims to conduct a review of the disease epidemiology between 2017 and 2023 and implications for surveillance in Imo State. Surveillance data from the Surveillance Outbreak Response and Management System (SORMAS) was extracted between January 2017 and December 2023 across the 27 Local Government Areas (LGAs) of Imo State. A line list of 231 suspected cases was downloaded into an excel template and analyzed using SPSS® version 20 software. Analysis was done using descriptive statistics and associations were tested using Fischer’s exact at 0.05 level of significance. Of the 231 suspected cases, 57.1% (132) were males, 42.9% (99) were females and the modal age group was between the ages of 0 - 4 (32.5%). Eight (8) LGAs (districts) accounted for 71% (n = 164) of all the suspected cases. 21.2% (49) were confirmed positive, 27 males (55.1%) and 22 females (44.9%) (p > 0.05). Modal age group was 20 - 24 (22.4%, n = 11), 18% (9) were children under 14 years, p > 0.05. Case fatality rate was 8% (n = 4). There was no significant association between mortality and age group. Five (5) LGAs accounted for about 60% (29) of all confirmed cases. These LGAs contribute only 20% to the total population in the State. Only 5.6% and 4% of suspected and confirmed cases, respectively, had knowledge of contact with an infectious source. The study described the epidemiology of Mpox outbreaks between 2017
