Study Notes
Infectious Diseases
Definition and Types
- Infectious diseases: illnesses caused by the presence of pathogens such as bacteria, viruses, fungi, or parasites in the body
- Types:
- Bacterial infections (e.g., tuberculosis, pneumonia)
- Viral infections (e.g., influenza, HIV)
- Fungal infections (e.g., candidiasis, ringworm)
- Parasitic infections (e.g., malaria, tapeworm)
Transmission and Spread
- Modes of transmission:
- Direct contact (e.g., touching, kissing)
- Indirect contact (e.g., contaminated surfaces, food, water)
- Airborne transmission (e.g., coughing, sneezing)
- Vector-borne transmission (e.g., mosquitoes, ticks)
- Factors influencing spread:
- Poor hygiene and sanitation
- Lack of vaccination
- Weakened immune system
- Global travel and commerce
Prevention and Control
- Methods:
- Vaccination
- Improved hygiene and sanitation
- Use of personal protective equipment (PPE)
- Vector control (e.g., insecticides, mosquito nets)
- Quarantine and isolation
- Importance of:
- Handwashing
- Proper food handling and storage
- Avoiding close contact with infected individuals
Vaccine-Preventable Diseases
- Examples:
- Measles, mumps, and rubella (MMR)
- Influenza (flu)
- Hepatitis A and B
- Human papillomavirus (HPV)
- Pertussis (whooping cough)
- Importance of vaccination:
- Reduces disease incidence and transmission
- Protects vulnerable populations (e.g., young children, elderly)
- Helps prevent outbreaks and epidemics
