Nonenveloped viruses

Cell parasites that do not have viral envelopes covering their central Capsid. Noroviruses but also rota- and adenoviruses are typical representatives. In contrast to Enveloped viruses, nonenveloped viruses are characterised by a higher resistance to chemical, physical procedures and other environmental influences and, if applicable, require the use of particularly powerful disinfectants that possess virucidal activity.
