Infection: Definition, Sources, and Nature
What is an Infection?
An infection is the invasion and multiplication of harmful microorganisms (bacteria, viruses, fungi, protozoa, rickettsia) in the body, causing disease. It can be localized (affecting one area) or generalized (spreading throughout the body).
Common Symptoms of Infection:
- Pain
- Swelling
- Redness
- Fever (high temperature)
- Increased pulse rate
- Leukocytosis (high white blood cell count)
Sources of Infection
1. Human Sources:
- Infected individuals (patients, healthcare workers, visitors)
- Carriers (people who harbor pathogens without symptoms)
- Normal flora (microbes normally present in the body but can become infectious)
2. Environmental Sources:
- Soil (e.g., anthrax, tetanus)
- Water (e.g., cholera, hepatitis viruses)
- Food (e.g., salmonella, contaminated pork)
- Insects (e.g., malaria, dengue)
- Inanimate objects (fomites) (e.g., hospital equipment, contaminated surfaces)
Nature of Infection
1. Infectious Agents: Microorganisms that cause diseases are called pathogens. If they spread easily from person to person, they are called communicable diseases.
2. Colonization vs. Infection:
- Colonization: Microbes grow on/in the body but do not cause disease.
- Infection: Microbes invade tissues and cause harm.
3. Body’s Defense Mechanisms Against Infection:
- Skin: Acts as a protective barrier; constantly sheds dead cells.
- Mucous Membranes: Trap microbes and prevent entry.
- Tears & Saliva: Wash away harmful particles.
- Stomach Acid: Kills bacteria in food.
- Cilia in Airways: Remove microbes before they reach the lungs.
- Immune System: Fights off infections through white blood cells and antibodies.
Routes of Infection Entry
- Skin (cuts, wounds, insect bites)
- Respiratory System (airborne infections like tuberculosis, COVID-19)
- Digestive System (contaminated food and water, causing cholera, typhoid)
- Urinary & Genital Tract (sexually transmitted infections)
- Bloodstream (through needles, transfusions, or insect bites)
Prevention of Infections
- Hand hygiene (washing hands with soap)
- Proper food handling (avoiding contaminated food/water)
- Vaccination (protecting against communicable diseases)
- Use of protective equipment (gloves, masks, sterilization in healthcare settings)
- Safe sex practices (using protection to prevent STDs)
- Insect control (mosquito nets, repellents to prevent malaria, dengue)
Chain of Infection
A susceptible host or the presence of a pathogen alone does not guarantee an infectious process. The chain of infection describes how an infectious process develops. It involves an interaction between the agent, host, and environment. Several essential elements, or “links in the chain,” must be present for microorganisms to be transmitted and cause infection. Understanding this process helps in controlling or eliminating microorganisms by breaking the links in the chain.

Links in the Chain of Infection:
- Infectious Agent
- Reservoir
- Portal of Exit
- Mode of Transmission
- Portal of Entry
- Susceptible Host
1. Infectious Agent
The infectious agent is the microorganism responsible for causing disease. Its ability to thrive depends on three factors:
- Virulence: Severity or harmfulness of the microorganism.
- Invasiveness: Ability to enter tissue.
- Pathogenicity: Ability to produce or cause disease.
Types of Infectious Agents:
- Viruses: Obligate intracellular agents requiring host machinery for replication. Classified by their nucleic acid type (DNA or RNA) and capsid shape.
- Bacteria: Unicellular organisms without chlorophyll, possessing both DNA and RNA. Classified by shape as cocci (spherical) or bacilli (rod-shaped).
- Fungi: Eukaryotic organisms lacking chlorophyll, reproducing by budding or spore formation. Types include molds, yeasts, yeast-like fungi, and dimorphic fungi.
- Protozoan Parasites: Single-celled eukaryotes that cause diseases and are often transmitted by insect vectors.
- Helminths: Multicellular parasitic worms with complex life cycles. Includes roundworms, flatworms, and flukes.
2. Reservoir
A reservoir is a place where microorganisms can thrive and reproduce. It can be:
- Animate: Humans, animals, birds, and insects.
- Inanimate: Soil, water, food, feces, intravenous fluids, and medical equipment.
Types of Carriers:
- Healthy Carrier: Harbors the pathogen without symptoms.
- Convalescent Carrier: Recovered but still carries the pathogen.
- Incubatory Carrier: Infectious before symptoms appear.
- Inapparent Carrier: Transmits infection without developing symptoms.
- Chronic Carrier: Recovered but continues to carry the pathogen.
Human Reservoirs and Transmission:
Reservoir | Transmission Vehicle | Infectious Agent |
---|---|---|
Blood | Needle stick, contaminated equipment | Hepatitis B, C, HIV/AIDS, S. aureus |
Tissue | Wound drainage | S. aureus, E. coli, Proteus species |
Respiratory Tract | Airborne droplets | Influenza, SARS, Klebsiella, S. aureus |
Gastrointestinal Tract | Vomitus, feces, saliva | Hepatitis A, Shigella, Salmonella |
Urinary Tract | Urine | E. coli, Enterococci, Pseudomonas |
Reproductive Tract | Urine, semen | N. gonorrhoeae, T. pallidum, Herpes simplex, Hepatitis B |
3. Portal of Exit
The portal of exit is the path through which pathogens leave the reservoir. Examples include:
- Respiratory Tract: Exhaled droplets (coughing, sneezing, talking, breathing).
- Gastrointestinal Tract: Stool, vomit (e.g., Hepatitis A).
- Skin: Wound drainage or lesions.
- Blood: Transmission through transfusion or direct contact.
4. Mode of Transmission
The mode of transmission describes how the infectious agent moves from the portal of exit. It travels to the portal of entry of a new host. The five primary transmission modes include:
a) Contact Transmission:
- Direct Contact: Physical transfer via touching, kissing.
- Indirect Contact: Transfer through contaminated objects like linens, dressings, and medical equipment.
b) Droplet Transmission:
- Infectious droplets from sneezing, coughing, or talking.
- Occurs within a 3-foot range.
c) Airborne Transmission:
- Inhalation of droplet nuclei or dust particles containing infectious agents (e.g., tuberculosis, measles, varicella).
d) Vector Transmission:
- Transmission by insects like mosquitoes (e.g., malaria) and fleas (e.g., plague).
e) Vehicle Transmission:
- Contaminated food, water, milk, drugs, or blood (e.g., hepatitis, HIV via blood transfusion).
5. Portal of Entry
The portal of entry is how the infectious agent enters a new host. Entry occurs through:
- Natural Orifices: Mouth, nose, vagina, urethra, ear, rectum.
- Artificial Orifices: Tracheostomy, ileostomy, colostomy.
- Mucous Membranes: Eyes, nasal passages, oral cavity.
- Skin Breaks: Cuts, wounds, invasive procedures.
- Ingestion & Inhalation: Swallowing contaminated food/water or breathing in infectious particles.
6. Susceptible Host
A susceptible host lacks immunity or has a weakened immune system, allowing infection to develop. Factors influencing susceptibility include:
- Age: Infants and the elderly have weaker immune responses.
- Chronic Diseases: Conditions like diabetes, cancer, and HIV/AIDS.
- Immunosuppressive Therapy: Chemotherapy, steroids, organ transplants.
- Malnutrition: Poor nutrition weakens the immune system.
Breaking the Chain of Infection
Preventing infection involves breaking any link in the chain:
- Eliminate Infectious Agents: Proper sterilization, hand hygiene, and disinfectants.
- Control Reservoirs: Isolate infected individuals, ensure food safety.
- Block Portals of Exit: Cover coughs and sneezes, use PPE.
- Interrupt Transmission: Hand hygiene, safe injection practices.
- Protect Portals of Entry: Proper wound care, safe catheter insertion.
- Boost Host Defenses: Vaccination, healthy lifestyle, adequate nutrition.
Types of Infection
- Acute Infection: Sudden onset, rapid progression, and severe symptoms lasting no more than six months.
- Chronic Infection: Slow progression with symptoms developing gradually over weeks or months and slow to resolve.
- Primary Infection: The initial infection in an otherwise healthy individual.
- Secondary Infection: Occurs during or after treatment for another infection due to immune system changes.
- Localized Infection: Restricted to a specific region in the body with local symptoms.
- Systemic Infection: Spreads throughout the body, affecting multiple regions.
- Clinical Infection: Shows observable and diagnosable signs and symptoms.
- Subclinical Infection: Few or no obvious symptoms; may be an early or mild stage of infection.
- Opportunistic Infection: Occurs more frequently in individuals with weakened immune systems.
- Nosocomial Infection: Acquired in a hospital environment.
- Focal Infection: Localized but can spread to other organs or structures.
- Cross Infection: Transmitted between patients via people, tools, or equipment.
- Iatrogenic Infection: A type of nosocomial infection caused by medical procedures.
- Endogenous Infection: Caused by infectious agents already present in the body.
- Exogenous Infection: Caused by pathogens from the external environment.
- Latent Infection: Remains dormant in tissues and becomes active when host resistance is lowered.
Stages of Infection
- Incubation Period: Time between exposure to the pathogen and the first symptoms.
- Prodromal Stage: Non-specific symptoms appear before more specific symptoms develop.
- Illness Stage: The acute phase with the most severe symptoms.
- Convalescence Stage: Symptoms disappear, and recovery begins.
Factors Increasing Susceptibility to Infection
- Age: Infants and older adults have weaker immune defenses.
- Sex: Some infections affect different sexes at varying frequencies.
- Heredity: Genetic factors influence susceptibility to infections.
- Stress: High stress levels weaken the immune system.
- Nutritional Status: Poor nutrition impairs immune function.
- Current Medical Therapy: Certain treatments weaken immune responses.
- Medications: Some medications suppress immune activity.
- Cancer: Certain cancers increase infection risk.
- Preexisting Medical Conditions: Chronic diseases can weaken immunity.
- Radiation: Destroys immune cells, increasing vulnerability to infection.
