Final answer:
A communicable disease that can be easily transmitted from person to person is referred to as a contagious disease. These are illnesses caused by pathogens and can spread through air, contact, food, or vectors. It differs from chronic, acute, and autoimmune diseases in its transmissibility.
Step-by-step explanation:
A communicable disease that can be easily transmitted from person to person is a contagious disease. Communicable diseases, often known as infectious diseases, are illnesses caused by pathogens such as viruses, bacteria, parasites, and fungi. These diseases can spread through various means such as air (when an infected person coughs or sneezes), physical contact, contaminated food or water, and also through vectors like mosquitoes. Examples of highly contagious diseases include measles and the common cold.It is important to differentiate between different types of diseases. Chronic diseases are long-term or lifelong diseases such as type 1 diabetes or cardiovascular diseases, which can sometimes be controlled but not always cured. On the other hand, acute diseases tend to be short-term, such as the flu.
Lastly, autoimmune diseases are conditions where the immune system mistakenly attacks the body, like in the case of lupus or rheumatoid arthritis.A communicable disease that can be easily transmitted from person to person is c) Contagious disease.An infectious disease is any disease caused by the direct effect of a pathogen. Some infectious diseases are also communicable, meaning they are capable of being spread from person to person through either direct or indirect mechanisms. Some infectious communicable diseases are also considered contagious diseases, meaning they are easily spread from person to person.For example, measles is a highly contagious viral disease that can be transmitted when an infected person coughs or sneezes and an uninfected person breathes in droplets containing the virus.
