How do virus die?
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 genetic instructions..
What was the first human virus?
The first human virus to be identified was the yellow fever virus. In 1881, Carlos Finlay (1833–1915), a Cuban physician, first conducted and published research that indicated that mosquitoes were carrying the cause of yellow fever, a theory proved in 1900 by commission headed by Walter Reed (1851–1902).
Are viruses created?
According to this hypothesis, viruses originated through a progressive process. Mobile genetic elements, pieces of genetic material capable of moving within a genome, gained the ability to exit one cell and enter another.

How do viruses infect humans?
At the molecular level, viruses invade cells and manipulate them to replicate, survive, and cause disease. Since they depend on human cells for their life cycle, one way viruses co-opt cellular machinery is through protein-protein interactions within their cell host.
How do viruses leave the body?
Mucus is designed to trap offending viruses, which are efficiently and quickly expelled from the body through coughing and sneezing. Fever—Fevers fight influenza viruses. Because viruses are sensitive to temperature changes and cannot survive above normal body heat, your body uses fever to help destroy them.
Can a virus be transmitted from human to human?
Avian influenza can also be spread through exposure to water and surfaces contaminated by bird droppings. Influenza viruses spread from human to human via aerosols created when an infected individual coughs or sneezes.
