Pathogens, Diseases and their prevention - JSS1 Physical and Health Education Past Questions and Answers - page 2

Pathogens are microorganisms that cause diseases. The main types are bacteria, viruses, fungi, and parasites.

Three diseases caused by bacteria are tuberculosis, strep throat, and urinary tract infections. Tuberculosis is a serious infectious disease that primarily affects the lungs and can spread through the air when an infected person coughs or sneezes.

Infectious diseases are caused by pathogens and can spread from person to person, while non-infectious diseases are not caused by pathogens and cannot spread from person to person. Non-infectious diseases are typically caused by genetic, lifestyle, or environmental factors.

Vaccinations help prevent the spread of infectious diseases by stimulating the immune system to recognize and fight specific pathogens, thereby providing immunity without causing the disease.
