Review of measles notification data within the integrated disease surveillance and response (IDSR) in Nigeria (2012-2016)

Gloria Oiyahumen Anetor

Abstract


Background: Nigeria is among the 45 countries that account for 94% of the global deaths due to measles. This study examined measles data retrospectively for five years in other to ascertain measles trend and epidemiology, focusing on timeliness and completeness of data, attack rate (AR) and Case fatality rate (CFR) in order to proffer solutions to reduce measles cases in Nigeria.

Methodology: A retrospective survey design. Permission granted by Nigeria Centre for Disease Control, Abuja to use existing routine measles and outbreak notification data from 2012 – 2016. Using SPSS 20, the data was collated, analyzed and interpreted using percentages, graphs and Chi square at 0.05 significant level.

Results: A very low rate of laboratory confirmed cases was revealed. There is a significant difference in the number of cases of measles in the age groups (p < 0.05). Children in the age group of 1 – 5 years mostly affected. There is a significant difference in the cases of measles in terms of geopolitical zone distribution (p < 0.05); the northern zones were more affected. There is a significant difference in the number of deaths recorded for measles (p < 0.05); the case fatality rate (CFR) and attack rate (AR) show that deaths from measles were highest among children under 5 years. Timeliness and completeness of reporting data indicate poor quality in gathering measles data.

Conclusion: From data analyzed, IDSR appears to have an ineffective case management system and poor data reporting quality. There is the need for more proactive and efficient surveillance to combat measles.
