Infectious particles without own metabolism containing genetic material in form of nucleic acid. Viruses either have a lipoprotein envelope or no envelope. As they do not carry out metabolic processes themselves, they require host cells to replicate. Enveloped viruses (HIV, hepatitis B or C virus, herpes simplex virus) are inactivated by disinfectants relatively easily. In contrast, nonenveloped viruses (poliovirus, adenovirus) need disinfectants tested for virucidal activity.
The A-to-Z database provides information on each pathogen, the most common infections that it triggers, its main transmission paths and recommendations on disinfection. In the glossary, you will find explanations of infection control terms. Search now!
