Hi @reddust
When foreign objects are contaminated into the human body. These foreign objects are germs, viruses, fungus or parasites. These organisms are transmitted by infection from another person, animals, contaminated food, or exposure to any environmental factors that are contaminated with any of these objects.

These infections have many symptoms on the body, including high body temperature and aches, in addition to other symptoms vary depending on the location of infection, type and severity of infection. It is possible to develop an infection that causes mild illness, and therefore requires no more treatment than home treatment. In contrast, there are serious cases that may cause death.
