Are you talking about INSIDE the infected cell, or outside? Secondarily, are they really alive anyway, and how do you define life? A virus is essentially a particle of DNA or RNA, and an envelope or microscopic ‘machine’ to deliver it into cells, ...


Strictly speaking, viruses can’t die, for the simple reason that they aren’t alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can’t thrive independently. Instead, they must invade a host organism and hijack its ...


There are many myths and misconceptions about how long human immunodeficiency virus (HIV), the virus that causes AIDS, lives and is infectious in the air or on a surface outside the body.


Since viruses lack many of the basic structures and functions necessary to be considered a living organism, they technically cannot die. Since most viruses are deactivated at temperatures between 165 and 212 degrees Fahrenheit, food scientists advise to heat up meat to at least 165 degrees before serving. These temperatures kill bacteria, as well.


This year's flu season is off to a killer start — literally. The Centers for Disease Control and Prevention (CDC) reported that rates of hospitalizations and deaths from the virus are higher ...


A virus is a small infectious agent that replicates only inside the living cells of an organism. Viruses can infect all types of life forms, from animals and plants to microorgani


Most viruses do not cause serious diseases and are killed by the body's immune system—its network of natural defenses. In many cases, people never even know they have been infected. But unlike bacteria, which can be killed by antibiotics, most viruses are not affected by existing medicines. ...


The host cell is now no longer useful to the virus, therefore the cell often dies and the newly produced viruses must find a new host. The process by which virus progeny are released to find new hosts, is called shedding. This is the final stage in the viral life cycle. Viral latency


How Long Does It Take For Shingles to Heal? The varicella-zoster virus never leaves your body once you have picked it up. For approximately two-thirds of people, after their childhood chickenpox trauma, they never see a resurgence of the virus. The other unlucky few may have shingles pop up for them later in life, especially after the age of 50.


There are viruses recovered from egyptian mummies that still functions! So to answer your question, viruses do "die" as part of their life cycle inside a host (because it gets destroyed after it inserts DNA/RNA, or another way of saying is that it's just a protein capsule left there doing nothing).
