Profiling the immunity status of children with non-polio acute flaccid paralysis who had not received any doses of oral polio vaccine in the South-South region, Nigeria 2011-2014.

OBJECTIVES: To demonstrate the immunity status of children with non-polio acute flaccid paralysis (NP AFP) reported through the AFP surveillance system in the South-South region of Nigeria. STUDY DESIGN: A retrospective study was conducted using AFP surveillance data collected routinely between January 2011 and December 2014 by the Disease Surveillance Department of the regional health service and the World Health Organization (WHO)-accredited regional reference polio laboratory. All cases of AFP reported to the Disease Surveillance Network from all six zones during this period were included in the study. METHODS: In total, 5111 cases of AFP in children aged ≤15 years were reported between 2011 and 2014. These cases were investigated and verified by WHO surveillance officers using a standard questionnaire, which captured the number of doses of oral polio vaccine (OPV) received by the child. Two stool samples were collected for each case, 24-48 h apart, within 14 days of the onset of paralysis, and transported to the national polio laboratory under reverse cold chain storage. Data retrieved were stored in an AFP database hosted by the WHO server. EPIINFO software was used to query the database and extract the information required for analysis in this study. RESULTS: The percentage of children who had received at least three doses of OPV (which serves as a threshold to measure immunity status) decreased from 87% in 2011 to 82% in 2014. The percentage of children who had not received any doses of OPV decreased from 2% in 2011 to 1% in 2014. Forty-eight percent of the children who had not received any doses of OPV were aged <1 year. CONCLUSION: Given the decrease in OPV immunity status, the region risks re-introduction of poliovirus. Swift steps should be taken to improve the immunization coverage, which would boost immunity status in Nigeria.

Characterization and management of solid medical wastes in the Federal Capital Territory, Abuja Nigeria.

BACKGROUND: Medical establishment such as hospitals and research institutes generate sizable amount of hazardous waste. Health care workers, patients are at risk of acquiring infection from sharps and contamination of environment with multiple drug resistant microorganisms if wastes are not properly managed. OBJECTIVES: To characterize types and evaluate waste disposal techniques employed in the management of solid medical wastes in five selected hospitals in the Federal Capital Territory, Abuja. METHODS: This was a cross section study involving the use of questionnaires, in-depth interview, meetings, discussions and participant observed strategy. It also involved the collection, sorting (segregation), identification and characterization and weighing of waste types from wards and units in the selected hospitals. RESULTS: The average waste generation rate per bed/day was determined and found to be 2.78 kg of solid waste, 26.5% of the total waste was hazardous in nature. Waste segregation was found not to be practiced by any of the hospitals surveyed, 18.3% of the hospitals incinerated waste in a locally built brick incinerator; 9.1% bury; 36.3% burn waste in open pits while 36.3% dispose of a waste into municipal dumpsites. CONCLUSION: Waste management officers do not have formal training in waste management techniques; and hospital administrators pay very little attention to appropriate management of medical waste. Therefore, we must educate waste generators of their responsibility to properly manage the waste so that their staff, patients, environment and community is protected.

The problems of indeterminate HIV results in blood transfusion services in Nigeria.

Five hundred sera samples were collected from individuals whose age range was 16-40 years, analysed using Murex 1 and 2 and Capillus HIV kit (Cambridge Biotechnology, Cambridge, UK), and confirmed with Western Blot technique (Biorad). Of these, 186 (37.2%) were repeatedly reactive, 90 (48.4%) were confirmed positive, 55 (29.6%) indeterminate (20 [10.7%] from blood donors) and 44 (22.0%) were negative. The data reveal a significant correlation between indeterminate results and confirmed positive sera (P < 0.05). This demonstrates the high incidence of indeterminate HIV results encountered in blood transfusion services.
