Coloured transmission electron micrograph (TEM) of chikungunya viruses particles. This alphavirus is composed of an RNA (ribonucleic acid) genome (dark brown) enclosed in a protein coat,or nucleocapsid,which is itself surrounded by a lipoprotein envelope. The virus,which is transmitted by mosquitoes,causes a rare form of viral fever. Symptoms include a high fever,rash and arthritic joint pain. There is no vaccine or treatment for the disease,which although often severe is rarely fatal. Magnification: x 98,000 when printed at 10 centimetres wide | |
