Passage 1 - Infectious Disease
An Infectious Disease Is A Clinically Evident Illness Resulting From The Presence Of
Pathogenic Agents, Such As Viruses, Bacteria, Fungi, Protozoa, Multi-Cellular Parasites,
And Unusual Proteins Known As Prions. Infectious Pathologies Are Also Called
Communicable Diseases Or Transmissib Diseases, Due To Their Potential Of Transmission
From One Person Or Species To Another By A Replicating Agent (As Opposed To A
Toxin).
Transmission Of An Infectious Disease Can Occur In Many Different Ways. Physical
Contact, Liquids, Food, Body Fluids, Contaminated Objects, And Airborne Inhalation Can
All Transmit Infectin

Agents.
Transmissible Diseases That Occur Through Contact With An Ill Person, Or Objects
Touched By Them, Are Especially Infective, And Are Sometimes Referred To As
Contagious Diseases. Communicable Diseases That Require A More Specialized Route Of
Infection, Such As Through Blood Or Needle Transmission, Or Sexual Transmission, Are
Usually Not Regarded As Contagious.
The Term Infectivity Describes The Ability Of An Organism To Enter, Survive And Multiply
In The Host, While The Infectiousness Of A Disease Indicates The Comparative Ease With
Which The Disease Is Transmitted. An Infection However, Is Not Synonymous With An

Infectious Disease, As An Infection May Not Cause Important Clinical Symptoms.
1. What Can We Infer From The First Paragraph In This Passage?
a. Sickness From A Toxin Can Be Easily Transmitted From One Person To Another.
b. Sickness From An Infectious Disease Can Be Easily Transmitted From One Person To
Another.
c. Few Sicknesses Are Transmitted From One Person To Another.
d. Infectious Diseases Are Easily Treated.
2. What Are Two Other Names For Infections’ Pathologies?
a. Communicable Diseases Or Transmissible Diseases
b. Communicable Diseases Or Terminal Diseases
c. Transmissible Diseases Or Preventable Diseases
d. Communicative Diseases Or Unstable Diseases
3 . What Does Infectivity Describe?
a. The Inability Of An Organism To Multiply In The Host
b. The Inability Of An Organism To Reproduce
c. The Ability Of An Organism To Enter, Survive And Multiply In The Host
d. The Ability Of An Organism To Reproduce In The Host
4. How Do We Know An Infection Is Not Synonymous With An Infectious Disease?
a. Because An Infectious Disease Destroys Infections With Enough Time.
b. Because An Infection May Not Cause Important Clinical Symptoms Or Impair Host
Function. C. We Do Not. The Two Are Synonymous.
D. Because An Infection Is Too Fatal To Be An Infectious Disease.

, A Virus (From The Latin Virus Meaning Toxin Or Poison) Is A Small Infectious Agent That
Can Replicate Only Inside The Living Cells Of Other Organisms. Most Viruses Are Too
Small To Be Seen Directly With A Microscope. Viruses Infect All Types Of Organisms, From
Animals And Plants To Bacteria And Single-Celled Organisms.
Unlike Prions And Viroids, Viruses Consist Of Two Or Three Parts: All Viruses Have Genes
Made From Either DNA Or RNA, All Have A Protein Coat Thatnursylab.Com - The Marketplace To Buy And Sell
Your Study Material Protects These Genes, And Some Have An Envelope Of Fat That Surrounds
Them When They Are Outside A Cell. (Viroids Do Not Have A Protei Coat And Prions
Contain No RNA Or DNA.) Viruses Vary From Simple To Very Complex Structures. Most
Viruses Are About One Hundred Times Smaller Than An Average Bacterium. The Origins
Of Viruses In The Evolutionary History Of Life Are Unclear: Some May Have Evolved From
Plasmids— Pieces Of DNA That Can Move Between Cells—While Others May Have
Evolved From Bacteria.
Viruses Spread In Many Ways; Plant Viruses Are Often Transmitted From Plant To Plant By
Insects That Feed On Sap, Such As Aphids, While Animal Viruses Can Be Carried By
Blood-Sucking Insects These Disease-Bearing Organisms Are Known As Vectors. Influenza
Viruses Are Spread By Coughing And Sneezing. HIV Is One Of Several Viruses
Transmitted Through Sexual Contact And By Exposure To Infected Blood. Viruses Can
Infect Only A Limited Range Of Host Cells Called The “Hos Range”. This Can Be Broad As

When A Virus Is Capable Of Infecting Many Species Or Narrow.
5. What Can We Infer From The First Paragraph In This Selection?
a. A Virus Is The Same As Bacterium
b. A Person With Excellent Vision Can See A Virus With The Naked Eye
c. A Virus Cannot Be Seen With The Naked Eye
d. Not All Viruses Are Dangerous
6 . What Types Of Organisms Do Viruses Infect?
a. Only Plants And Humans
b. Only Animals And Humans
c. Only Disease-Prone Humans
d. All Types Of Organisms
7 . How Many Parts Do Prions And Viroids Consist
Of? A. Two
b. Three
c. Either Less Than Two Or More Than Three
d. Less Than Two
