Micrographs of DENV2 (IMAGE) Duke-NUS Medical School Caption Micrographs of DENV2 with different distribution of smooth and bumpy surfaced particles when incubated at different temperatures to mimic the physiological temperature in the mosquitoes (29°C, left panel), human host (37°C, middle panel) and when humans are experiencing high fever (40°C, right panel). Colour gradient from blue to red shows the rise in temperature.
