a new host comes. When the new host comes and drinks from the water source, the pathogens take this opportunity to enter the host. Once the pathogens enter the body, the host would be infected. Besides transmitting disease through everyday drinking water and the air, another way of transmitting diseases are by contact. Chicken Pox and Small Pox are some of the many diseases that can be caused by contact Venereal diseases like gonorrhea and syphilis can also be transmitted by contact. An example of a disease that can be transmitted if there is a wound would be our very familiar Tetanus. An example of how someone would acquire tetanus from a wound would be like this: The construction worker moves around a lot and works very hard. Down on the floor is a tetanus-infected nail. As the worker is too busy caring for his job, he accidentally steps on the nail and gives the tetanus bacteria a chance to get into the body. The tetanus would be successful from coming from the nail and going to the host. As the wound would close very quickly, this provides an oxygen free atmosphere in which the tetanus bacteria could start to get active. Immune carriers can be classified as those who have recovered from a certain disease and is immune to it, but still carries the pathogens. The immune carriers show no indication of a disease with any symptoms, but this carrier can still transmit these pathogens to others. One major disease carrier is the Anthropoid. They pick up the pathogens in their food, where they walk and other places. As they carry the disease, they move to other places either for food or shelter purposes. When they bite or sting other organisms, the disease is transmitted through the anthropoid and infects a new host. The skin is the main protector from pathogens. The first line of defense is the structure of the skin itself. It is almost impossible for pathogens to pass the skin layer. Those who do would go through the pores in our skin. ...
