2. pathogens enters through through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier
3. important to overall good health, regular exercise keeps your body strong to protect against diseases
ACTIVITY 3
1. Sterilization destroys all microorganisms on the surface of an article or in a fluid to prevent disease transmission associated with the use of that item. While the use of inadequately sterilized critical items represents a high risk of transmitting pathogens, documented transmission of pathogens associated with an inadequately sterilized critical item is exceedingly rare.
2. Pasteurization involves heating liquids at high temperatures for short amounts of time. Pasteurization kills harmful microbes in milk without affecting the taste or nutritional value (sterilization= all bacteria are destroyed).
3. Steam inhalation is one of the most widely used home remedies to soothe and open the nasal passages and get relief from the symptoms of a cold or sinus infection.
Steam inhalation is one of the most widely used home remedies to soothe and open the nasal passages and get relief from the symptoms of a cold or sinus infection.Also called steam therapy, it involves the inhalation of water vapor. The warm, moist air is thought to work by loosening the mucus in the nasal passages, throat, and lungs. This may relieve symptoms of inflamed, swollen blood vessels in your nasal passages
4. Boiling is a very simple method of water disinfection. Heating water to a high temperature, 100°C, kills most of the pathogenic organisms, particularly viruses and bacteria causing waterborne diseases. In order for boiling to be most effective, the water must boil for at least 20 minutes.
5. Disinfecting uses chemicals (disinfectants) to kill germs on surfaces and objects. Some common disinfectants are bleach and alcohol solutions. You usually need to leave the disinfectant on the surfaces and objects for a certain period of time to kill the germs.

Activity 2
1. A pathogen in the oldest and broadest sense, is any organism that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ.
2. Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.
3. Important to overall good health, regular exercise keeps your body strong to protect against diseases such as heart disease, diabetes, bone loss and some cancers.
Activity 3
1. Medical devices that have contact with sterile body tissues or fluids.
2. Beer , Canned goods , Dairy products , Eggs , Fruit juices , Milk , Nuts , Syrup.
3. Foods like vegetables , chikens , and shellfish.
4. Most foods, especially meat, poultry, fish and eggs, should be cooked thoroughly to kill most types of food poisoning bacteria.
5. Surfaces and objects that are touch often.
