Introduction:
Diseases can be classified into two types: infectious and non-infectious. Both types of diseases have different causes, symptoms, and treatments.

Infectious Diseases:
Infectious diseases are caused by pathogenic microorganisms such as bacteria, viruses, fungi, and parasites. These microorganisms can spread from one person to another through direct contact, contaminated food or water, or inhaling airborne particles. Examples of infectious diseases include:

- Common cold
- Influenza
- Tuberculosis
- Malaria
- HIV/AIDS
- Ebola

Symptoms of Infectious Diseases:
Symptoms of infectious diseases can vary depending on the type of disease, but can include:

- Fever
- Chills
- Cough
- Fatigue
- Diarrhea
- Vomiting
- Skin rashes

Treatment of Infectious Diseases:
Treatments for infectious diseases can include antibiotics, antiviral medications, antifungal medications, or antiparasitic medications. In some cases, vaccines can also prevent infectious diseases.

Non-Infectious Diseases:
Non-infectious diseases are caused by genetic factors, lifestyle choices, or environmental factors. These diseases cannot be spread from one person to another. Examples of non-infectious diseases include:

- Cancer
- Diabetes
- Heart disease
- Stroke
- Alzheimer's disease
- Parkinson's disease

Symptoms of Non-Infectious Diseases:
Symptoms of non-infectious diseases can vary depending on the type of disease, but can include:

- Fatigue
- Pain
- Numbness
- Weakness
- Memory loss
- Difficulty breathing

Treatment of Non-Infectious Diseases:
Treatments for non-infectious diseases can include medications, surgeries, lifestyle changes such as diet and exercise, or therapies such as chemotherapy or radiation.

Conclusion:
Infectious and non-infectious diseases differ in their causes, symptoms, and treatments. It is important to understand the differences between the two types of diseases in order to prevent their spread and effectively treat those who are affected.
