What Are Viruses?

Viruses have been hitting the headlines a lot recently. A virus is simply a tiny submicroscopic viral agent that replicates within the living cells of a living organism. Viruses can infect all forms of living organisms, from plants and animals to humans and microorganisms, such as bacteria. They can also invade the living tissues of other organisms through a process called infection, where they replicate and spread throughout the body.

What are viruses made of? In order for the viruses to replicate themselves and continue they require a living host. For example, the influenza virus replicates in the lungs of people who are suffering from the condition, and then it is able to spread throughout the body, and affect other areas.

Whilst antibiotics are used in the fight against bacterial infections, viruses are tougher to defeat. There are antiviral medications but these don’t work for every viral infection. Vaccines remain an essential tool in the fight against viruses, for example, the successful flu vaccine that is rolled out every autumn.

Viruses are tiny, microscopic even and much smaller than bacteria. They also cannot survive very long outside of a living host. Despite their bad reputation for being behind outbreaks of disease, viruses are highly useful for scientists in furthering research.
