We present biological insights into the co-infection of chikungunya and dengue to elucidate the phenomena clearly. Therefore, we develop a mathematical model to conceptualize the intricate dynamics of chikungunya and dengue co-infection. We investigate the models of dengue fever and chikungunya separately, examining their local and global asymptotic stability. It has been shown that these models have a unique endemic steady state. Moreover, we demonstrate that both diseases are uniformly persistent when the reproduction parameter exceeds one. The endemic indicator, which is the reproduction value of the co-infected model, is computed as the maximum of the reproduction values of dengue and chikungunya. Moreover, the theory of optimal control is implemented using four distinct strategies to reduce infection levels: prevention through insect repellents, control via vaccination, and vector reduction through larvicides and adulticides. Finally, we investigate the system numerically to illustrate the overall dynamics of co-infection under optimal control measures and to assess the effectiveness of these control policies.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A8008524">Cited in <strong>2</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A92D30" title="MSC2020">92D30</a> </td> <td class="space"> Epidemiology </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Aco-infection+model">co-infection model</a>; <a href="/?q=ut%3Adengue%2Fchikungunya">dengue/chikungunya</a>; <a href="/?q=ut%3Astability+analysis">stability analysis</a>; <a href="/?q=ut%3Aoptimal+control">optimal control</a>; <a href="/?q=ut%3Anumerical+simulation">numerical simulation</a>; <a href="/?q=ut%3Apublic+health">public health</a></div>  <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;">  </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function">  <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 08008524" data-ciurl="/ci/08008524" data-biburl="/bibtex/08008524.bib" data-amsurl="/amsrefs/08008524.bib" data-xmlurl="/xml/08008524.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/08008524.pdf" title="Zbl 08008524 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.3934/dcdss.2024109" aria-label="DOI for “Modeling the co-dynamics of vector-borne infections with the application of optimal control theory”" title="10.3934/dcdss.2024109">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">B.
