Nonenveloped viruses (such as adenoviruses) usually leave an infected cell by lysing it. For enveloped viruses (such as retroviruses), the nucleocapsid is enclosed within an envelope derived from cellular membranes, making these viruses more labile to heat, drying, detergent, and other harsh treatments.
