Answer:
1. chicken pox
2. infectious disease
3. non-infectious disease
4. pathogens
5. bacteria and viruses
6. vectors
7. immunization
Step-by-step explanation:
An infectious disease, also known as transmissible disease or communicable disease, is a type of disease caused by microorganisms (e.g., bacteria, viruses, fungi, etc) that can be passed from person to person, while a non-infectious disease cannot be spread from person to person but can be genetically inherited across generations (e.g., certain types of cancer). A pathogen is any type of organism that causes diseases to its host, which can be an infectious agent (e.g., a virus). Chickenpox is a contagious (transmissible) disease caused by the varicella-zoster virus (VZV), which is a class of herpes viruses. Chickenpox is spread by the saliva of infected individuals released into the air when breathing, coughing, sneezing, or speaking. Vectors are organisms that do not cause diseases but help in transmitting them (e.g., Aedes aegypti is a mosquito vector that transmits different diseases such as yellow fever and dengue). Finally, immunization refers to the medical procedure that stimulates a person's immune system to produce immunity against a specific disease (e.g., vaccination is a type of immunization).
