Communicable Disease vs. Non-Communicable Disease

The difference between communicable and non communicable diseases is that communicable diseases spread from one person to another person directly or indirectly via water, wind, food, blood, droplets or any other way while non communicable diseases are not transferred from one person to another but they are produced due to allergy, autoimmune process, inherited, chromosomal defects or any other pathological process .

A disease is the manifestation of illness occurring in the body. Broadly diseases are classified into two types, i.e., communicable and noncommunicable diseases. Communicable diseases are those which are transferred from one person to another by direct contact or indirectly by food, water, wind, blood, vectors, droplets or any other way. The underlying cause of communicable diseases is an infection either viral, bacterial, fungal or parasitic. Noncommunicable diseases are those diseases which are not transferred from one person to another rather they occur due to any allergy, autoimmune process in the body, inherited or chromosomal defects, inflammation or any other pathological in the body. Noncommunicable diseases may occur due to infection, trauma or any of the above-mentioned reasons but usually, they are noninfectious diseases.

Communicable diseases are not inherited from one generation to another while noncommunicable diseases can be inherited.

Communicable diseases are usually acute (short duration and severe in nature) while noncommunicable diseases are usually chronic (develops slowly over a period of time and long lasting).

The examples of communicable diseases can be given as TB, AIDS, cholera, malaria, meningitis, influenza, cholera, pertussis, etc. The examples of noncommunicable diseases can be given as allergies, cancer, rickets, osteomalacia, Crohn’s disease, gastritis, heart diseases, and lung or kidney diseases, etc.

The precautions to avoid communicable diseases are to wear a mask, care for your hygiene, hand washing practice, vaccinations and stay away from the source of infection. The precautions for noncommunicable diseases include undergoing medical check-up routinely, to maintain a proper diet and to take proper exercise daily.

Vaccination can be done for communicable diseases but cannot be done for noncommunicable diseases.

The treatment of communicable diseases is done by antibiotics, antiviral, antifungal or antiparasitic drugs accordingly. The treatment of noncommunicable diseases is done by conservative management or by surgical intervention.

Comparison Chart

Basis Communicable diseases Non communicable diseases
Definition They are such types of diseases which are transferred from one person to another by direct contact or indirectly via wind, water, food, blood, droplets, vector or any other source. Noncommunicable diseases are such types of diseases which are not transferred from one person to another. They take place due to any pathological process in the body.
Underlying causes The underlying cause of these types of diseases are infections either viral, bacterial, fungal or parasitic. The basic reasons for these types of diseases are trauma, inflammation, allergies, an autoimmune process, inherited or chromosomal defects.
Inheritance  They are not inherited in the next generation. They may be inherited from one generation to the next one.
Examples Examples can be given as influenza, meningitis, pertussis, cholera, diarrhea, malaria etc. Their examples can be given as chronic heart diseases, kidney or lung diseases, diabetes, allergies, rickets, osteomalacia, pancreatitis or peptic ulcer disease, etc.
Duration They are usually acute (for short duration and severe in nature). They are usually chronic (develop slowly over a period of time and long-lasting.
Treatment Their treatment is done by antibiotics, antiviral, antifungal or antiparasitic drugs accordingly. Their treatment is done by conservative management or by surgical approach.
Vaccination Vaccination for these types of diseases is available. No vaccination is possible for these types of diseases.
Prevention Prevention can be done by wearing mask, good hand washing practice, maintaining hygiene and staying away from the source of infection. These types of diseases can be avoided by maintaining a good lifestyle, by undergoing a routine medical check-up, maintaining a good diet and taking exercise daily.

What are Communicable Diseases?

Communicable diseases are such types of diseases which are transferred from one person to another directly or indirectly. The modes of indirect transmission of such types of diseases are food, water, wind, insects, droplets, blood or other things. Sexually transmitted diseases also fall under this category which is transferred by sexual intercourse. Communicable diseases are usually acute in onset, i.e., they are sudden in onset, severe in nature and of short duration. Signs and symptoms of communicable diseases depend upon the type of infection, but some of the commonly occurring symptoms are diarrhea, malaria, vomiting, fever, rashes on the body, muscle pain, flu, headache, myalgias, running nose, itching, and lightheadedness.  The symptoms of sexually transmitted diseases like syphilis and gonorrhea are itching in the genital area and greenish discharge.

The agents for infectious diseases may be bacteria, virus, fungus or protozoa. The symptom of a bacterial infection is a high-grade fever. There is either no fever or low-grade fever in viral infections. These diseases are treated with antibiotics, antiviral drugs, antifungal or antiprotozoal drugs depending upon the nature of infection.

What are Non-Communicable Diseases?

Noncommunicable diseases are those types of diseases which are not transferred from one person to the other one. The underlying cause of these types of diseases may be inflammation, allergy, an autoimmune process, trauma, inherited or chromosomal defects. Noncommunicable diseases are usually chronic, i.e., they develop slowly over a period of time and long-lasting. The examples can be given as heart diseases, peptic ulcer disease, lung disease, kidney diseases, diabetes, osteomalacia, rickets, etc. The treatment is done by conventional conservative methods or by surgical intervention. These diseases may run in families. Vaccination from these types of diseases is not possible.

Key Differences between Communicable Disease and Non-Communicable Disease

  1. Communicable diseases are those who transfer from one person to another while noncommunicable diseases do not transfer from person to person.
  2. Communicable diseases are acute, e., of short duration while noncommunicable diseases are chronic, i.e., of long duration.
  3. Communicable diseases do not inherent to the next generation while noncommunicable diseases may be inherited.
  4. Vaccination from communicable diseases is available but not possible for noncommunicable types
  5. Communicable diseases occur due to any infection while noncommunicable diseases occur due to any other pathological process.

Conclusion

Diseases can be divided into two types, i.e., communicable diseases and noncommunicable diseases. Both types are common all over the world. The underlying causes and treatment for both types are different. It is mandatory to know the difference between both types of diseases. In the above article, we learned the clear differences between communicable and noncommunicable diseases.
