In healthier patients, the same virus may be mostly uncomfortable though it is fatal in more immunocompromised patients.
What is a Virus Made of? What is a Basic Characteristic of a Virus?
Trying to dissect the issues leads many to wonder what is a virus made of? They consist of a core of RNA or DNA genetic material with a protective coating of protein called a capsid. Capsids occasionally have a spikey protective coat called an envelope.
Knowing what a virus is made of, what is a basic characteristic of a virus? They are acellular, meaning that they do not have cytoplasm or organelles. They do not have a metabolism, and require this of a host’s machinery, which is how they reproduce. While they may have DNA or RNA, they do not have both.
What is a Syndrome? What is the Difference Between Virus and Syndrome?

So, what is a virus? An organism that causes disease in the host body it infects as a means of surviving and reproducing, neither of which it can do on its own. What is a syndrome? A collection of symptoms caused by a particular disease, which may be viral infection, bacterial infection, or even caused by other means. What is the Difference Between Virus and Syndrome?
