INTRODUCTION
An infection can be referred to as the invasion of the body tissues of an organism by way of
disease causing agent (like bacterium, fungi, parasite and virus), their growth, together with the
reaction of host tissues upon the infectious agent & toxin produced by them. An infection may
tend to result into not a single symptom and be subclinical or there is even a probability that
infection may result into symptom along with being clinically apparent (Berríos-Torres and et.
al., 2017). Besides this, infection control can be viewed as a chain of steps that are undertaken
within health care facility or hospitals for prevention or control of spread of infections. Some of
the most commonly used ways for controlling or preventing infection spread are isolation,
hygiene practices and drugs or immunisation. The current report seeks to explore information
about infectious diseases and effectiveness of some ways to prevent and control its spread. Also,
it consists of signs and symptoms of three infectious diseases.
Infectious Diseases
Explain what is meant by “Infectious Diseases” (A/C 1.1)
Infectious diseases can be referred to as the disorders that are caused by way of organisms like
virus, bacterium, fungi, parasite etc. There are several organisms which sustain in or over the
human body (Friedman and et. al., 2017). They are assumed to be helpful or, in other terms,
harmless. However, there are several instances whereby they may result into a disease.
Discuss the differences between Bacterial, Fungal and Viral infections (A/C 1.2)
The bacterial, viral and fungal infections tend to possess several differences which are studied in
a brief manner as follow:-
Bacterial infections Fungal infections Viral infections
Bacteria give rise to
bacterial infections.
Fungi tend to cause fungal
infection.
Viral infections are caused
by viruses.
Certain examples of
infections caused by
bacteria include whooping
cough, ear infection,
Urinary Tract Infection
(UTI), strep throat, etc.
Some examples of fungal
infection consists of athlete's
foot, jock itch, ringworm,
yeast infection etc.
Some of the most common
and renowned examples of
viral infection include
common cold, flu, warts etc.
