It occurs when another organism enters your body and causes disease. The organisms that cause infections are very many they can include things like viruses, bacteria, fungi or parasites.
You can acquire an infection in many different ways, such as directly from a person with an infection, through contaminated food or water, and even through the bite of an insect.
Let’s look at infections, the types of organisms that cause them, and actions you can take to help prevent becoming seriously sick.
Viruses are tiny infectious organisms. They are even smaller than bacteria. A virus is composed of a piece of genetic material that’s surrounded by a protein shell. Some viruses may have an additional envelope and other features on their surface.
Viruses are parasitic and require a host body in which to carry out their life cycle. Once the virus has entered the host cell, will be able to use cellular components to reproduce. New viruses are released from the host cell, a process will sometimes causes the host cell virus, examples:
- Lassa fever,
- Common cold,
- Mononucleosis infectious,
- Viral meningitis,
The treatment of viral infections centers on relieving symptoms until your immune system clears the infection.
In some cases, antiviral drugs may be available to help treat a viral infection. Some examples of viral infections for which antivirus are available include HIV, Hepatitis C and Herpes.
Note that antibiotics are not effective in treating a viral infection.
