Background: The last case of the indigenous Wild Polio Virus in Ondo state was in 2008, and the last Polio compatible infection was in 2010. Poliovirus transmission was stopped thanks to the World Health Organization's (WHO) standards, which included acute flaccid paralysis (AFP) surveillance. We wanted to describe the state's polio surveillance performance during the last five years, from 2016 to 2020, using WHO-recommended measures and find areas where it could improve.Methods: Between January 2016 and December 2020, AFP case-based surveillance data was used to undertake a retrospective examination of records. Microsoft Excel was used for data processing, and Quantum Geographic Information System was used for mapping (GIS).Results: From 2016 to 2020, a total of 1,096 AFP instances were recorded, none of which were confirmed as Poliomyelitis. The bulk of the cases (77.2 percent) were found in children under the age of five. Males made up more than half of the cases (53.4%). More than 89 percent of reported cases received three or more OPV doses. Between 2016 and 2020, there was a 79 percent decline in reported incidents. Between 2016 and 2020, the average Non-Polio AFP rate was 11.2 per 100,000, with a stool adequacy of 98.4%.Conclusion: AFP surveillance in Ondo state met the minimum WHO targets during the study period, according to the findings. However, because of the possibility of poliovirus being imported from endemic countries, which might threaten Nigeria's polio-free status, all surveillance actors' sensitization and active case search should be strengthened, particularly in underperforming local government areas (LGAs).

Background: Acute gastroenteritis, a very common disease in humans affecting both children and adults, remains a major public health concern worldwide. Several groups of viruses have been reported as the causative agents of acute gastroenteritis. An outbreak of acute gastroenteritis with a high fatality rate was reported in Ondo State, Southwest, Nigeria, in September 2020. Methods: To provide a descriptive epidemiology of the outbreak, a field investigation was carried out in affected communities in September 2020. Results: Four Local Government Areas (LGA) were affected, with Odigbo LGA having the highest attack rate of 14.9 per 100,000 population. The epidemic curve was propagated in nature. 50 cases were reported with 21 deaths (42%). The outbreak primarily affected 15-year-olds (94%, n=47) and more males (58%, n=29). Conclusion: Poor sanitation, food, and water hygiene conditions in communities of the LGA visited were observed. The spread of the outbreak was probably facilitated by water sellers.
