Each virus is different in its own nature and the way itaffects the human beings. Viruses are common and they affect all human beingsbut they are not all harmful. Some viruses can be spread through the air andthey get to the orifice inside a human by means of inhalation through thelungs. Some other types can be spread only through body fluids. HIV can bespread by blood contact.

Viruses are often mistakenly compared to bacteria, butthey are totally different organisms. Bacteria are a type of organism that feedsof a host and leads a self sustaining life. Virus is more like a geneticinformation that clings to the cells of a host and exploits the cells for itsown reproduction. The main difference between the bacteria and the viruses isthat the infection caused by bacteria can be efficiently localized whileviruses systematically affects the entire body.

Flu and cold viruses are the most common of them all. Thesetypes of viruses can have minimal to moderate effect on the human body unlessthe patient is an infant that cannot defend the body properly or an old or anill person whose protective capabilities are significantly diminished. Thehuman body is meant to fight bacteria and viruses so when a person experiencesa viral infections, the symptoms are actually the body’s response as it triesto eradicate the virus.

These symptoms usually include a runny nose, sneezing,coughing, loss of energy, swollen lymph glands, flushed face and bodytemperature. When a person suffers from a viral infection the body createsantibodies whose purpose is to find any foreign material in the body anddestroy it. In this case the viruses are that foreign material. When theviruses attack the human body, it is trying to defend itself and the firstsigns of the infection are actually indications of the immune system fighting backand trying to kill the virus off.

Fever is triggered because the human body purposely raisesits temperature for just a few degrees because it helps in killing off thevirus. Runny nose is very common if a person has the flu or a cold. Runny noseconsists of white blood cells. The immune system reacts to the materials thatare supposed to kill the virus and the removal of dead virus materials.

A runnynose makes sure that all those unwanted materials get released from the body.Coughing and sneezing serves the exact same purpose as a runny nose does. Lymphglands get swollen because they work hard to produce the material that issupposed to kill the viruses off. The loss of energy, aching, pain anddehydration occurs because the energy gets diverted from normal bodilyactivities towards killing the viruses more efficiently.
