Dengue fever virus replication. Coloured transmission electron micrograph (TEM) of dengue fever virus particles (red) replicating in a cell. The many virions are forming in spaces in the cell cytoplasm near to the nucleus (blue,upper right),by a process known as condensation. They will then leave the cell. Dengue is transmitted by mosquitoes,replicating chiefly in the immune system's macrophage cells. It causes fever,headache and joint pain,often with a rash. Severe cases result in haemorrhages and hypovolaemia,a dangerously low level of circulating blood. Magnification: x16,500 at 6x7cm size | |
