Here are the definitions for the key terms in your infection control list. These explanations are written to be clear and easy to understand for your homework.

1. Asepsis
The state of being free from disease-causing microorganisms (like bacteria and viruses). In healthcare, it refers to practices used to prevent infection, such as washing hands or using sterile tools during surgery.

2. Autoclave
A machine that uses high-pressure steam to sterilize equipment. It gets hot enough to kill all bacteria, viruses, fungi, and spores on surgical instruments and other medical tools.

3. Bacteria
Tiny, single-celled living organisms. Some bacteria are helpful (like those in our stomachs), but others can cause diseases and infections. They are one of the most common types of germs.

4. Blood borne pathogens
Germs (such as viruses or bacteria) that are present in blood and can cause disease if they enter another person’s body. Common examples include Hepatitis B, Hepatitis C, and HIV.

5. Carrier
A person or animal that has a disease-causing germ in their body but does not show symptoms of being sick. Even though they feel fine, they can still pass the disease to others.

6. Chain of infection
The series of steps that must happen for an infection to spread. It usually includes: the infectious agent (germ), the reservoir (where it lives), the portal of exit (how it leaves), mode of transmission (how it travels), portal of entry (how it gets in), and the susceptible host (the person who gets sick). Breaking any link in this chain stops the infection.

7. Communicable disease
An illness that can be passed from one person to another, or from animals to people. Examples include the flu, chickenpox, and measles.

8. Compromised host
A person whose immune system is weak and cannot fight off infections well. This could be due to age (very young or very old), illness (like cancer or HIV), or medications (like chemotherapy).

9. Contaminated
Something that is dirty because it has come into contact with harmful germs, chemicals, or radioactive material. For example, a bandage with blood on it is considered contaminated.

10. Direct contact
When an infection spreads through physical touching between two people. This includes kissing, shaking hands, or touching body fluids like blood or saliva directly.

11. Fomite
An inanimate (non-living) object that can carry germs and spread infection. Common fomites include doorknobs, towels, utensils, and toys. If a sick person touches a doorknob, and then you touch it and rub your eyes, the doorknob acted as a fomite.
