1. Direct contact: This mode of transmission occurs when an infected person comes into physical contact with a susceptible person, allowing the disease-causing microorganism to be passed from one person to another. This can include touching, kissing, or sexual contact.
2. Indirect contact: In this mode of transmission, the disease-causing microorganism is passed from an infected person to a susceptible person through a contaminated object or surface. This can include touching contaminated surfaces, sharing personal items, or using contaminated medical equipment.
3. Airborne transmission: This mode of transmission occurs when infectious droplets containing the disease-causing microorganism are released into the air and inhaled by a susceptible person. This can happen through coughing, sneezing, or talking.
4. Vector-borne transmission: In this mode of transmission, disease-causing microorganisms are transmitted to humans through the bites of vectors such as mosquitoes, ticks, or fleas. These vectors can carry and transmit the pathogens from infected animals to humans.
5. Waterborne transmission: This mode of transmission occurs when disease-causing microorganisms are transmitted through contaminated water sources. This can happen through drinking contaminated water, swimming in contaminated water, or consuming contaminated food washed in contaminated water.
6. Foodborne transmission: In this mode of transmission, disease-causing microorganisms are transmitted through contaminated food or beverages. This can happen through consuming food that has been contaminated during preparation, storage, or handling.
7. Fecal-oral transmission: This mode of transmission occurs when disease-causing microorganisms are transmitted through contact with fecal matter. This can happen through poor sanitation practices, contaminated food or water, or inadequate hand hygiene.
