communicable diseases

• What is the main topic discussed in the material?

  Communicable disease
• What are pathogens?

  Microorganisms that enter the body and cause disease
• What types of organisms can be infected by pathogens?

  Both plants and animals
• How do pathogens cause communicable diseases?

  They cause diseases that can easily spread
• What are bacteria described as in the material?

  Very small living cells
• How small are bacteria compared to human body cells?

  About 1/100th the size
• What can bacteria do inside the body?

  Reproduce rapidly
• What can bacteria produce that affects the body?

  Toxins that damage cells
• What are viruses described as in the material?

  Not cells and much smaller
• How do viruses reproduce?

  Inside the host's cells
• What is the size comparison of viruses to bacteria?

  Viruses are about 1/100th the size
• What do viruses do inside the body?

  They replicate using the host's machinery
• What happens to the host cell after a virus replicates?

  The cell bursts, releasing new viruses
• What is the effect of cell damage caused by pathogens?

  It can make you feel ill
• What type of cells are protists described as?

  Single-celled eukaryotes

  Fungi can be parasitic
• How do fungi reproduce?

  They can reproduce through spores
• What is a characteristic of parasitic fungi?

  They live on or inside other organisms
• How do parasitic fungi cause damage?

  By harming their host organisms
• What is the role of vectors in disease transmission?

  They transfer pathogens to hosts
• How do vectors affect the spread of diseases?

  They facilitate the transmission of pathogens
• How do vectors contribute to the life cycle of pathogens?

  They help pathogens reach new hosts

  They have unique mechanisms of infection
• What is the relationship between pathogens and their vectors?

  Vectors facilitate the transmission of pathogens
• How do the characteristics of pathogens influence disease spread?

  Pathogen characteristics determine transmission methods
• What role do environmental factors play in the spread of communicable diseases?

  They can enhance or inhibit disease transmission
• How can understanding pathogens lead to better health outcomes?

  It allows for targeted prevention and treatment
• What is the importance of studying the life cycle of pathogens?

  It helps identify intervention points for control
• How do pathogens adapt to their hosts?

  They evolve mechanisms to evade immune responses
• What strategies can be employed to control the spread of communicable diseases?

  Vaccination and public health measures
• How can public awareness impact the spread of diseases?

  It can lead to better prevention practices
