I.  Text

Text : Human infections

  Human infections are caused by either bacteria or viruses. Bacteria are tiny single-celled organisms, thought by some researches to be related to plants. They are among the most successful life forms on the planet, and range in habitat from ice slops to deserts. Bacteria can be beneficial for instance, gut bacteria help us digest food-but some are responsible for a range of infections. These disease-causing varieties are called pathogenic bacteria. Many bacterial infections can be treated successfully with appropriate antibiotics.

   A virus is an even smaller micro-organism that can only reproduce inside a host cell. It is very difficult to kill a virus. That is why some of the most serious communicable diseases known to medical science are viral in origin.

   To bring about a disease, pathogenic bacteria must gain access into the body. The range of access routes for bacteria includes contaminated food or water, close contact with faces, often of an infected person, breathing in the exhaled droplets when an infected person cough or sneezes.

   Virus are spread from one person to another by cough, sneezes, bites from infected animals or insects, exposure to infected bodily fluid.
