Health is defined as a state of complete physical, mental, and social well-being, allowing one to have a positive outlook and cope well with stress. Disease impairs the normal functioning of the body and is a response to various environmental, infectious, or inherited factors. There are two main types of diseases: those present since birth due to genetic or organ abnormalities, which are generally permanent and inheritable; and acquired diseases after birth, which include infectious diseases spread between people or non-infectious diseases due to dietary or tissue degeneration issues.

2. Health has been described as the
state of complete physical, mental
and social well being.
Thus, being healthy means that
you have a positive outlook and
are able to cope up with any kind

the vital functions and is a
response to environmental
factors to specific agents to
inherent defects of the organisms
or to combination of these
factors.

5. 
These diseases are present since
birth. They are caused due to
genetic abnormality or due to
metabolic or malfunctioning of any
organ.
They are permanent and cannot be
easily curable and may be inherited
to the children.

6.  These diseases are those which
develop after birth.
Acquired diseases are broadly divided
into
Two typesInfectious diseases
Non infectious diseases

7. 
These diseases are caused by some
biological agents or pathogens such
as viruses, bacteria, helminthes and
fungi.
These diseases can rapidly spread
from one person to another by various
means such as by physical contact,
water, air, food and insects

9. Symptoms

Headache and typhoid fever which rises
maximum in the afternoon.

High fever in the second week. Fever gradually
declines.

In nutshell symptoms of typhoid include
continuous fever often with delirium, slow
pulse, diarrhoea with water-green stools.

10. Prevention
 Proper sanitation and disposal of
faecal matter prevents infection.
 TAB-vaccination provides
immunity for 3 years.
 Typhoral oral vaccine also
prevents typhoid.

11. 

These diseases are restricted only to those
persons who are suffering from them. These
are not spread from infected person to
healthy person.
These diseases may be caused from the
lack of certain essential substances in our
diet; general degeneration of tissues;
uncontrolled growth of tissues (cancer);
defects in the metabolic reactions; and
injury and damage to any part of the body
part.

13. Providing
vaccines at right
time.
