“…However, there was an overall reduction of 15.9% coverage rate during the pandemic. This reduction may put the state at the risk of yellow fever outbreak bearing in mind its proximity to Kwara state where an outbreak was reported in 2017 [25]. For this reason, a strong epidemiologic watch is duly recommended.…”

“…re-assortment mechanisms, repeated bottlenecks may result in the stepwise accumulation of deleterious mutations in a ratchet-like manner. Each of these mutations has a low probability of direct reversion unless the population size remains above ~10 4 (the reciprocal of the mutation frequency for a given nucleotide). Muller's ratchet has been demonstrated to occur experimentally with several arboviruses 19,20 , which underscores the risk they face if they are subjected to repeated bottlenecks during their transmission cycle (requiring replication and spread in divergent hosts) 21 .…”

“…However, four arboviruses with non-human primate enzootic hosts have initiated human-amplified transmission cycles that last from months to centuries, which increases their ability to infect humans and to cause human disease. These include dengue virus (DENV), which infects nearly 400 million humans annually throughout many tropical and subtropical regions and causes disease in nearly 100 million individuals, thus making DENV the most important arbovirus 2 ; and yellow fever virus (YFV), which despite the availability of an effective vaccine for nearly a century still infects tens of thousands of humans annually, with recent epidemics in Brazil 3 , Nigeria 4 and Angola 5 . In addition, the past 15 years have brought unexpected outbreaks caused by two other human-amplified arboviruses, namely chikungunya virus (CHIKV) and Zika virus (ZIKV).…”

“…In Nigeria, infectious diseases constitute significant disease burden in the country. Prior to the onset of the global pandemic of SARS-COV2 infection, national reports and statistics regarding specific infectious diseases in Nigeria were already alarming, and while plans were being made to mitigate these, the results have been at best moderately effective (1).…”
