Zvirwere zvinogona kuiswa mumapoka zvichienderana nesero ravanorwara naro: mavhairasi emhuka, mavhairasi emiti, mavhairasi ehonye, uye mabhakitiriya (mavhairasi anorwara nebhakitiriya, ayo anosanganisira mavhairasi akaomesesa). Imwe nzira yekumisikidza inoshandisa chimiro chechimiro che capsid yavo (kazhinji helical kana icosahedron) kana chimiro chehutachiona (semuenzaniso kuvapo kana kusavapo kwehomwe yemvura). Mavirusi ane saizi kubva pa30 nm kusvika pa450 nm, zvinoreva kuti mazhinji acho haagone kuonekwa nemicroscopes yechiedza. Chimiro uye chimiro chehutachiona chakadzidzwa neelectron microscopy, NMR spectroscopy, uye X-ray crystallography. Mubvunzo: Ndeapi maviri maumbirwo ejometri ari macapsid?
