    <p>In “Early Detection of Dengue Fever Outbreaks Using a Surveillance App (Mozzify): Cross-sectional Mixed Methods Usability Study” (JMIR Public Health Surveill 2021;7(3):e19034) two errors were noted.</p>
    <p>In the originally published manuscript, the footnotes of Tables 1 and 3 listed incorrect currency conversions. In Table 1, footnote “b” originally read:</p>
    <disp-quote>
      <p>Philippine peso (US $48.10=<inline-graphic xlink:href="publichealth_v7i4e29795_fig1.png" xlink:type="simple" mimetype="image"/>1)</p>
    </disp-quote>
    <p>In Table 3, footnote “d” originally read:</p>
    <disp-quote>
      <p>Philippine peso (US $52.16=<inline-graphic xlink:href="publichealth_v7i4e29795_fig1.png" xlink:type="simple" mimetype="image"/>1)</p>
    </disp-quote>
    <p>In the corrected version of the manuscript, both of these footnotes have been changed to read:</p>
    <disp-quote>
      <p>Philippine peso (US $1=<inline-graphic xlink:href="publichealth_v7i4e29795_fig1.png" xlink:type="simple" mimetype="image"/>50.5; 5-year average rate)</p>
    </disp-quote>
    <p>The correction will appear in the online version of the paper on the JMIR Publications website on April 22, 2021, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories.</p>
