Study Notes

Modes of Transmission and Infection

  • Respiratory tract serves as the portal of entry for infections.
  • Airborne transmission occurs through the evaporation of respiratory droplets, involving the respiratory tract.
  • Fomites or indirect contacts involve contaminated objects as a mode of transmission for infections.
  • Normal flora, a common source of infection, is characterized by the presence of microorganisms that colonize the body but do not cause disease in healthy individuals.
  • Airborne transmission involves the evaporation of respiratory droplets during cough or sneezing, allowing the infection to spread.
  • Respiratory tract serves as the portal of exit for infections.
  • Normal flora is a source of infection characterized by the presence of microorganisms that colonize the body but do not cause disease in healthy individuals.
  • Fomites or indirect contacts involve contaminated objects as a mode of transmission for infections.
