Journal of Mosquito Research 2024, Vol.14, No.4, 184-194 http://emtoscipublisher.com/index.php/jmr 188 Figure 2 The distributions of chikungunya, dengue, yellow fever and Zika virus infections in humans in Africa (Adopted from Weetman et al., 2018) Image caption: (a) Areas at risk of one, two, three or all four infections; map generated as described in Supplementary Methods. (b) Locations of reported infections (symptomatic and non-symptomatic) of dengue, chikungunya, Zika and yellow fever (Adopted from Weetman et al., 2018) Weetman et al. (2018) found that the spatial distribution of chikungunya, dengue, yellow fever, and Zika virus infections in Africa shows significant overlap, particularly in central and western regions. This overlap suggests that these regions are at a higher risk of multiple disease outbreaks, potentially complicating public health responses. The study highlights the critical need for integrated surveillance and control strategies that consider the co-occurrence of these diseases, especially in areas where the environmental conditions favor the spread of multiple arboviruses. Moreover, the presence of reported infections in both symptomatic and non-symptomatic individuals underscores the challenge of accurately assessing the true burden of these diseases, emphasizing the importance of enhancing diagnostic and reporting mechanisms across the continent. The findings of this study are crucial for informing targeted interventions and resource allocation to mitigate the impact of these diseases in Africa.
