Dengue Virus is Hyperendemic in Nigeria from 2009 to 2020: A Contemporary Systematic Review.

Infect Chemother 2021 Jun;53(2):284-299

Department of Nursing Science, Maryam Abacha American university of Niger, Maradi, Niger Republic.

Backround: Data on Dengue virus (DENV) infection prevalence, geographic distribution and risk factors are necessary to direct appropriate utilization of existing and emerging control strategies. This study aimed to determine the pooled prevalence, risk factors of DENV infection and the circulating serotypes within Nigeria from January 1, 2009 to December 31, 2020.

Materials And Methods: Twenty-one studies out of 2,215 available articles were eligible and included for this systematic review. Relevant articles were searched, screened and included in this study according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) criteria. The risk of bias in primary studies was assessed by Cochrane's method. Heterogeneity of pooled prevalence was calculated using the chi-square test on Cochrane's Q statistic, which was quantified by I-square values. The random-effects analyses of proportions were used to determine the pooled prevalence of DENV antibodies, antigen and RNA from eligible studies.

Results: Of these, 3 studies reported co-circulation of all the 4 serotypes, while 2 separately reported co-circulation of DENV-1 &2 and DENV-1 to -3. All the antibody-based studies had significantly high heterogeneity (I² >90%, <0.05), while the NS1 and PCR-based studies had low heterogeneity (I² <25%, >0.05). The pooled prevalence of DENV IgM, IgG, RNA, NS1 and neutralizing antibodies were 16.8%, 34.7%, 7.7%, 7.7% and 0.7%, respectively. South-east Nigeria had the highest pooled DENV-IgG seropositivity, 77.1%. Marital status, gender, educational level and occupation status, the proximity of residence to refuse dumpsite, frequent use of trousers and long sleeve shirts were significantly associated with DENV IgG seropositivity ( <0.05).

Conclusion: Based on these findings, it can be inferred that Nigeria is hyperendemic for Dengue fever and needs concerted efforts to control its spread within and outside the country.

The pattern of human papillomavirus infection and genotypes among Nigerian women from 1999 to 2019: a systematic review.

Ann Med 2021 12;53(1):944-959

WHO National Polio Reference Laboratory, University of Maiduguri Teaching Hospital, Maiduguri, Nigeria.

Background: There are no robust national prevalence of Human Papillomavirus (HPV) genotypes in Nigerian women despite the high burden of cervical cancer morbidity and mortality.

The Objective Of Study: This study aims to determine the pooled prevalence and risk factors of genital HPV infection in Nigeria through a systemic review protocol.

Methods: Databases including PubMed, Scopus, Google Scholar and AJOL were searched between 10 April to 28 July 2020. HPV studies on Nigerian females and published from April 1999 to March 2019 were included. GRADE was used to assess the quality of evidence.

Results: The pooled prevalence of cervical HPV was 20.65% (95%CI: 19.7-21.7). Genotypes 31 (70.8%), 35 (69.9%) and 16 (52.9%) were the most predominant HPV in circulation. Of the six geopolitical zones in Nigeria, northeast had the highest pooled prevalence of HPV infection (48.1%), while the least was in the north-west (6.8%). After multivariate logistic regression, duration (years) of sexual exposure (OR = 3.24, 95%CI: 1.78-9.23]), history of other malignancies (OR = 1.93, 95%CI: 1.03-2.97]), history of sexually transmitted infection (OR = 2.45, 95% CI: 1.31-3.55]), coital frequency per week (OR = 5.11, 95%CI: 3.86-14.29), the status of circumcision of the sexual partner (OR = 2.71, 95%CI: 1.62-9.05), and marital status (OR = 1.72, 95%CI: 1.16-4.72), were significant risk factors of HPV infection ( < 0.05). Irregular menstruation, post-coital bleeding and abdominal vaginal discharge were significantly associated with HPV infection ( < 0.05).

Conclusion: HPV prevalence is high in Nigeria and was significantly associated with several associated risk factors. Rapid screening for high-risk HPV genotypes is recommended and multivalent HPV vaccines should be considered for women.
