“…In our previous studies we established the presence of arboviruses capable of causing human diseases and belonging to three of the four virus families already highlighted [12,13,14,15,16]. As our findings suggest, DENV is highly prevalent in Nigeria [13].…”

“…Worrisome however, is the neglect of arboviral infections in Nigeria, as well as in some other countries. For instance, based on our findings in 2016, we accentuated the imminence of yellow fever outbreak in Ilorin, Nigeria, owing to the nonchalance of people towards receiving vaccination, low anti-YFV IgG seropositivity, and the speculated circulation of the wild-type YFV [12]. If adequate attention had been given to the early warning, the outbreak of YV experienced in Ilorin, Nigeria, in 2017 [40], may have been averted.…”

“…Our previous study assessed the prevalence of anti-yellow fever virus (anti-YFV) immunoglobulin G (IgG) antibodies, providing evidence for past exposure to yellow fever virus (either the wild or vaccine strains). It was recorded that regardless of vaccination status of subjects, 21.6% of the subjects enrolled in the study were found to be seropositive to anti-YFV IgG antibodies [12]. This implies that in every five subjects there is approximately one subject who is seropositive for anti-YFV IgG antibodies.…”

“…The revelation is quite alarming for an infection that has a vaccine. However, our study did not record any positive cases of YFV RNA following RT-qPCR [12]. In a study conducted in Central African Republic, 37% of the participants (including people who reported previous yellow fever vaccination) were confirmed to have YFV antibodies [18].…”

“…Few of the vaccinees had evidence of a yellow card in support of their claim of been vaccinated. There was an overall low anti-YFV IgG seropositivity within the study population, and there seemed to be a delay in the YF outbreak within the study area in several years until after our study was concluded in 2016 [12]. This could be because of herd immunity against yellow fever [17].…”

The Neglect and Fast Spread of Some Arboviruses: A Note for Healthcare Providers in Nigeria

Arboviruses are distributed worldwide and constitute significant health burden globally. Outbreaks of arboviruses have been reported in Africa and beyond. In Nigeria, like in many other countries, arbovirus infections are more often than not neglected. As the early clinical features of arbovirus infections are generally nonspecific, most healthcare providers mistake them for other diseases. Outbreaks have been reported in Africa and beyond. The consequence of missed diagnosis of diseases cannot be overstated. In this review, some epidemiological data, classical syndromes, and risk factors for five human arboviruses (yellow fever YF, dengue DENV, chikungunya CHIKV, Rift Valley fever RVF, and West Nile virus WNV) found in Nigeria are presented. Health practitioners should ensure in-depth analysis rather than a superficial diagnosis of diseases before declaring a course of treatment.

The 2019 and 2020 sporadic outbreaks of Yellow fever (YF) in Sub-Saharan Africa (SSA) countries had raised a lot of global health concerns. This article aims to narratively review the vector biology, YF vaccination program, environmental factors and climatic changes, and to understand how they could facilitate the re-emergence of YF. This study comprehensively reviewed articles that focused on the interplay and complexity of YF Virus (YFV) vector diversity/competence, YF vaccine immunodynamics, and climatic changes impacts on YFV transmission as they influence the 2019/2020 sporadic outbreaks in Sub-Saharan Africa (SSA). Based on available reports, vectorial migration, climatic changes, and YF immunization level could be reasons for the re-emergence of YF at the community and national levels. Essentially, the drivers of YFV infection due to spillover are moderately constant. However, changes in land use and landscape have been shown to influence sylvan-to-urban spillover. Furthermore, increased precipitation and warmer temperatures due to climate change, are likely to broaden the range of mosquitoes' habitat. The 2019/2020 YF outbreaks in SSA is basically a result of inadequate vaccination campaigns, YF surveillance and vector control. Consequently, and most importantly, adequate immunization coverage must be implemented and properly achieved under the responsibility of the public health stakeholders.
