1. Presentation On
•Why do
we fall ill?

2. Chronic Diseases
• Chronic Disease
is a long-lasting
condition that
can be
controlled but
not cured.

3. Acute illnesses
are those that will
eventually
resolve without
any medical
supervision
(colds,
teething).

4. Infectious diseases
• Infectious diseases are
disorders caused by
organisms — such as
bacteria, viruses, fungi or
parasites. Many
organisms live in and on
our bodies. They're
normally harmless or
even helpful, but under
certain conditions, some
organisms may cause
disease.

5. Non infectious diseases
 Commonly known as
non-communicable
diseases, abbreviated
as NCDs, non-
infectious diseases are
those that are caused
by factors such as
genetics, environment,
and lifestyle, and not by
disease-causing
organisms. Non-
infectious diseases do
not pass on from one
person to another.

6. Infectious agents and diseases caused
by them
Virus
• A virus is a small infectious
agent that replicates only
inside the living cells of
other organisms. Viruses
can infect all types of life
forms,
from animals and plants to
bacteria and archaea.

7.  The common cold) is
a viral infectious
disease of the upper
respiratory
tract which primarily
affects the nose.

8. INFLUENZA
 Influenza, commonly
known as "the flu", is
an infectious
disease caused by
the influenza
virus. Symptoms can be
mild to severe.The most
common symptoms includ
e: a high fever, runny
nose, sore throat, muscle
pains, headache, coughing
, and feeling tired. These
symptoms typically begin
two days after exposure to
the virus and most last
less than a week.

9. BACTERIA
 Bacteria constitute a
large domain of prokaryotic micr
oorganisms. Typically a few
micrometres in length, bacteria
have a number of shapes,
ranging from spheres to rods
and spirals. Bacteria were
among the first life forms to
appear on Earth, and are
present in most of its habitats.
Bacteria inhabit soil,
water, acidic hot
springs,radioactive waste,and
the deep portions of Earth's
crust. Bacteria also live
in symbiotic and parasitic relatio
nships with plants and animals.
They are also known to have
flourished in manned
spacecraft.

10.  Typhoid fever — also
known simply
as typhoid— is a
common worldwide
bacterial disease
transmitted by the
ingestion of food or
water contaminated
with the feces of an
infected person, which
contain the
bacterium Salmonella
enterica subsp. enteric
a, serovarTyphi

11. Cholera
 Cholera is an
infection of the small
intestine caused by
the bacterium Vibrio
cholerae.

12.  A fungus is any member
of a large group
of eukaryotic organisms
that includes
microorganisms such
as yeasts and molds (Briti
sh English: moulds), as
well as the more
familiar mushrooms.

13. Athlete Foot
 Athlete's foot is a
common and
contagious dermato
phytic fungal
infection of the skin
that causes scaling,
flaking, and itching
of the affected
areas.

14.  Dermatophytosis is a
clinical condition
caused by fungal
infection of the skin
in humans, pets such
as cats, and
domesticated
animals such as
sheep and cattle.

15. Protozoa
• In some
biological taxonomy sch
emes, Protozoa are a
diverse group of
mostly motile unicellula
r eukaryotic organisms,
but the term is no
longer commonly used
in modern taxonomy.

16. MALARIA
 Malaria is a mosquito-borne
infectious disease of humans
and other animals caused by
parasitic protozoans of
the Plasmodium type. Malaria
causes symptoms that typically
include fever, fatigue, vomiting
and headaches. In severe cases
it can cause yellow
skin, seizures, coma or death.

17. Kala Azar
• Visceral
leishmaniasis (VL), also
known as kala-azar, black
fever, and Dumdum
fever,is the most severe
form ofleishmaniasis.
Leishmaniasis is
a disease caused
by protozoan parasites of
the Leishmania genus.

18.  A worm is an
elongated soft-
bodied invertebrate
animal, most
commonly
the earthworm.

19. Elephantiasis
• Elephantiasis is a
symptom of a variety of
diseases, where parts of
a person's body swell to
massive proportions.

20.  Helminths also
commonly known
as parasitic worms, are
large multicellular
organisms, which when
mature can generally be
seen with the naked
eye. They are often
referred to as intestinal
worms even though not
all helminths reside in
the intestines; for
example Schistosomes are
not intestinal worms, but
rather resides in blood
vessels.
