Nine diseases can be prevented by childhood immunisation such as diphtheria, tetanus, whooping cough, poliomyelitis (polio), measles, mumps, rubella, Haemophilus influenza type b, and hepatitis B. All of these diseases can cause serious problems and sometimes death if the body is not immune to them. When young the body has fewer antibodies making the body venerable to all these diseases the body builds antibodies to fight these diseases and viruses overtime as the virus is exposed to more viruses . When children are not immunised their risk to these diseases is very high and can cause severe reactions . For example in picture 5 the picture is of a six month old baby named Kailis Smith, who is in hospital because of a severe case of whopping cough. Whooping cough is a contagious disease that causes violent coughing fits that make it hard to breathe. It spreads easily when someone with the disease coughs or sneezes. The symptoms can last for months over exposing lung of babies leading to deaths. Kailis caught the disease from a person in his community who had not yet been immunised. About 29,000 children under the age of five – 21 each minute – die every day, mainly from preventable causes. Getting immunised potentially means stopping the spread of these disease from one to the other and lowering the rate of deaths in children.
One of the most common ways of catching a disease is through the spread of infected people being in contact with others physically or the spread of particles through the air. Some of the most common contagious viruses include Rhinovirus (the common cold), mumps, chickenpox, ringworm, scarlet fever, tinea, and the human swine flu. In 2009 there was a worldwide flu pandemic the second involving the influenza virus the first of them was the 1918 killing Between 50 and 100 million people, making it one of the deadliest natural disasters in human history. In April 2009 the virus was found to be a Reassortment (mixture) of bird, flu and human flu viruses combined with a Eurasian pig flu virus, (a newly mutated version of the old virus). Viruses know that once they
