What is ‘infection’.

When a foreign body or organism enters our body and causes harm, they result in an infection or a disease. This foreign organism uses our body’s healthy cells to colonize, sustain and reproduce itself. These infection causing organisms are known as pathogens and examples include viruses, bacteria, prions and fungi. Pathogens can adapt to our body’s conditions easily and multiply quickly. Bacteria and Virus are two such ‘foreign bodies’ that can lead to infection and diseases in humans.

What is a Virus and Viral Infection?


Almost every ecosystem on earth has viruses. They are the most plentiful biological system on this planet. Infection that is caused by a virus in the body is a viral infection. Different viruses can infect and cause a viral infection in nearly any type of body part or tissue, from the skin to the brain, depending on the virus and your state of health. Common cold, flu and warts are some well-known infectious diseases caused by viruses. On the other hand, severe ailments like smallpox, Ebola and even HIV/AIDS can also result from viruses. Virus attacks normal living cells and use those cells to reproduce other viruses, and ultimate result in a viral infection.
