Summary Introduction
Introduction:
Immune system of the human body is divided into two main branches namely the innate immunity and the adaptive immunity. Innate or the body’s first defense mechanism is present since birth and this defense mechanism is non-specific, which means it acts as a barrier in for every foreign body irrespective of its structure. Adaptive immunity of the body comes in later stages, when the body is introduced to pathogens. It is a specific type of defense mechanism.

Compared to enveloped viruses, these and other nonenveloped viruses tend to remain infectious outside the body longer, are more likely to be spread by contact with surfaces, and are less likely to be rendered harmless by exposure to hand sanitizer or hand washing. Explain how the lack of an envelope could contribute to these characteristics.arrow_forward
