PLEASE FAST!! WILL GIVE BRAINLIEST 30 POINTS!! Imagine you are sitting next to a person who has a very strong body odor on a crowded bus. All you can think about is getting off the bus, so you will not have to smell the person any longer. You know that body odor can mean someone has health problems, so you begin to fear for your own health. You have learned that if a person has significantly poor hygiene, it can cause harm for those around them.
Answer the following questions:
What are the differences between communicable and noncommunicable diseases?
What types of diseases can result from poor hygiene?
Is poor hygiene a symptom of a communicable disease? If so, which one?

Answers

Answer:

Communicable is able to be passed from person to person, for example: the flu, colds, and viruses. However non cummunicable, such as autoimmune diseases, cannot be spread from person to person and are typically inherited. Poor hygine is not a sypmtom of a communicable disease, but is instead a risk factor for a communicable disease.

Explanation:

Communicable diseases are those that may be transmitted from one person to another.

What is a communicable disease?

Noncommunicable diseases are those that cannot be communicated from one person to another, whereas communicable diseases are those that may be transmitted from one person to another.

Athlete's foot and body lice are two examples of the illnesses that can arise from improper hygiene. These relate to many strategies and tactics that restrict the spread of illnesses and preserve a healthy lifestyle.

As a result of the presence of microorganisms in a crowded or unclean environment, poor hygiene can contribute to the spread of infectious diseases.

Therefore, poor hygiene is a regular occurrence in areas of poverty and overcrowding, which encourages the spread of infectious illnesses and is harmful since it puts a load on the local healthcare system.
