When do we say that we have a disease? Is this disease spread from viruses or was it bacteria who originated it? If it was a virus then what are its symptoms and if it is a bacteria them how did it eventually give birth to such a disease? All of these are genuine questions, they make a lot of sense and these questions hit hard on a human mind to think that are diseases caused by bacteria or by virus?
So, now without wasting any time, let us jump on to our article
What is a disease?
The disease occurs when the cells of the body start degrading and as a result, you feel illness or restlessness in the body. It is caused when the microbes such as bacteria or viruses start to multiply in the body.
Four types of diseases are infectious disease, Deficiency diseases, Hereditary diseases, and Physiological diseases.
Infectious diseases are the disorder caused to the human body by pathogen microorganisms such as bacteria, viruses, parasites, and fungi.
A disease that is caused by the lack of a particular element in the diet mostly vitamin and mineral.
A disease that is transmitted from one generation to another, genetically. These are transmitted in similar families and chromosomes are responsible for this hereditary disease.
it is a disease where the organs in the body start malfunctioning and cause restlessness and illness. The common examples are Asthma and Diabetes.
Further diseases are classified into two types known as Communicable diseases and non-communicable diseases.
Also known as transmittable and infectious disease, these are transmitted through contact. Some of the communicable diseases are Ebola, Hepatitis A, Hepatitis B, Hantavirus, and the trendy virus that is Coronavirus (COVID- 19).
Non Communicable disease–
These are not transmitted through direct contact, it is a non-infectious health condition disease that is not spread through human to human and is known as a chronic disease. Most commonly it includes cardiovascular diseases and diabetes.
What is a Virus?
A virus is a submicroscopic infectious agent that multiplies itself inside the human body this is because they cannot reproduce outside the host’s body.
What is Bacteria?
Bacteria are microscopic living organisms that are unicellular or one-celled, which is found everywhere in the surroundings.
Bacteria are categorized into two types
Good and bad bacteria, Bad can be dangerous, such as when they cause infection, and beneficial as in the process of fermentation of wine or bread, breaking down food that helps in digestion and that of decomposition.

Virus Vs Bacteria
So, now let us know what are viruses and bacteria,
Latin mean poison and these are the microbes that invade in the body cells. Viruses contain genetic material like RNA (Ribonucleic acid) DNA (Deoxyribonucleic acid) and protein coat. Viruses can opt for any shape and they are very much smaller than bacteria 20- 400 nanometer.
- Viruses cause diseases such as common cold, sinus infection, acute bronchitis, and sore throats.
- Antibiotics cannot kill viruses.
- The virus infects the whole body and its organs.
Bacteria are a one-celled organism. These can live outside our body cells. Bacteria can take any shape like a sphere, round, rods, and spirals. They are found everywhere, in food, dirt, and surroundings. Some of the bacteria are good which helps in digestion while some cause infection. Their size is much larger that is around 1000 nanometer.
Bacteria cause infection such as strep throat, Pneumonia, meningitis, Tetanus, and food poisoning are some of the most common illness caused by harmful bacteria.
Antibiotics kill bacteria.
Bacterial infection infects in a specified location.
So, finally reading everything we can conclude that infection is caused by bacteria while diseases are caused by viruses.
