1.Epidemiology is the study and analysis of the distribution, patterns and determinants of health and disease conditions in defined populations. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare.
Epidemiology is a discipline that has a crucial role in describing health status, identifying risk factors, and analyzing relationships between health and different hazardous agents. The classical epidemiological triangle of host-agent-environment describes how individuals become ill.
2. -Wash your hands well. You probably wash your hands after using the bathroom, before preparing or eating food, and after gardening or other dirty tasks. You should also wash up after blowing your nose, coughing, or sneezing; feeding or stroking your pet; or visiting or caring for a sick person
-Cover a cough. Cover your mouth and nose with a tissue when you sneeze or cough, then dispose of it. If no tissue is handy, cough or sneeze into your elbow rather than into your hands.
-,Wash and bandage all cuts. Any serious cut or animal or human bite should be examined by a doctor
-Do not pick at healing wounds or blemishes, or squeeze pimples.
-Don't share dishes, glasses, or eating utensils.
-Avoid direct contact with napkins, tissues, handkerchiefs, or similar items used by others.
Explanation
B.
1.Many people do not realize that microbes can live on surfaces anywhere from a few minutes to several months, depending on the environment and pathogen type.
2.Good hygiene includes not only personal cleanliness but also the age-old practice of covering your mouth when you cough or sneeze. Many respiratory infections are spread by droplets, some of which may be small enough to become aerosolized and travel for long distances
3.Toothbrushes, towels, razors, handkerchiefs, and nail clippers can all be sources of infectious pathogens, including bacteria, viruses, fungi, and parasites. These objects are referred to as fomites (a term used to describe objects or materials that are likely to carry infection, such as clothes, utensils, or furniture)
4.Your immune system is designed to have a "memory" of previous infections, enabling a rapid response (in the form of antibodies, B-cells, and T-cells) should the pathogen ever return.
Vaccination does more or less the same thing, exposing the body to a weakened or killed form of the pathogen so that the same defensive cells are produced.
5.Food-borne illnesses frequently arise from poor food preparation. What many people do not realize is that most cases of gastroenteritis ("stomach flu") in adults are actually food poisoning.
