Compared to the case incidence in 2016, incidence was approximately five times higher in 2018 [incidence rate ratio (IRR): 4.8; 95% confidence interval (\n                      <jats:italic>CI<\/jats:italic>\n                      ) 1.5\u201315.3] and over 140 times higher in 2019 (IRR: 141.6; 95%\n                      <jats:italic>CI<\/jats:italic>\n                      45.8\u2013438.4). A one standard deviation increase in elevation was associated with a 90% decrease in reported case incidence (IRR: 0.10; 95%\n                      <jats:italic>CI<\/jats:italic>\n                      0.01\u20130.20). However, the association between elevation and reported cases varied across the years. In 2018 there was a cluster of cases reported from high elevation Kaski District of Gandaki Province. Our results suggest that dengue infections are increasing in magnitude and expanding out of the lowland areas to higher elevations over time.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>There is a high risk of dengue outbreak in the lowland Terai region, with increasing spread towards the mid-mountains and beyond as seen over the last 14\u00a0years.
