They are manifestation or evidence that suggest the presence of a disease, not a particular disease. Eg. A headache, Cough
They are distinct for particular diseases and provide information about the presence of a particular disease.
Diseases that last only for a short period of time. Eg. Common cold, Typhoid, Cholera
When the diseases last for a long time even as much as lifetime and have a drastic effect on the health of the individual and the patient can never fully recover. Eg. HIV-AIDS, Cancer, Elephantitis, TB
These are abnormalities of diseases that have been present in the induvidual since birth. They can be caused by a genetic mutation. Eg. Diabeties
Diseases that have developed after birth are called non-congelital or accquired diseases.
Diseases that occur due to external factors like pathogens and spread from infected to a healthy person.
Diseases that occur due to internal factors, caused by factors other than pathogens and cannot spread from infected to healthy people.
Causes of a disease which directly affect the sufferer for eg. microorganisms.
Causes of a disease which indirectly contribute to the disease. For eg. malnourishment, genetic factors like defective genes.
Level 3 Cause
Causes of a disease which are due to circumstances. For example poverty or lack of public cleanliness.
Categories of Pathogens
i) Bacteria ii) Viruses iii) Fungi iv) Protozoa v)Worm
When an infected patient sneezes or coughs, little droplets are thrown out containing pathogens. When these droplets are inhaled microbes get a chance at starting a new infection. Eg. Pneumonia, common Cold, TB
When safe drinking water is not available it becomes the means of spread for water-borne diseases. Eg. Cholera.
When the food is not properly cooked, i.e. raw meat acts as a way to spread diseases. Eg. Salmonella

i) Sexual Contact, ii) Blood Transfusion, iii) During pregnancy or breastfeeding iv) Needles or blades
When an animal carries an infection from a sick person to a potential host. These animals are intermediators. Eg. Malaria
they are chemicals capable of killing bacteria. They target the bio-chemical pathways important for bacertia.
It is a process in which an active immune system recruits many cells to the affected tissue to kill off the disease causing microbes.
This treatment provided to us which helps in the reducing of symptoms. Eg. i) fever reducing pills and painkillers or bedrest to conserve energy. It does not kill the infecting microbe.
Specific Method Treatment
In this kind of treatment, we use medicines that kill the microbes. It is very important to categorize the microbes so that the proper medicine can be used. Eg. Antibiotics cannot deal with viruses.
General Method Prevention
It mostly refers to preventing exposure. Eg. For airborne diseases, it can be done by living in less crowded places. Waterborne by providing safe drinking water
Specific Method Prevention
It relates to a peculiar property of the immune system that usually fights off microbial infection.
The immune system remembers every microbe that fights off, this helps it fight the microbe better next time. A vaccine injects a close relative of the microbe in the body so that the immune system knows how to fight off that particular microbe.
