Pathogens vary significantly in size depending on their type. Bacteria typically range from 0.5 to 5 micrometers, while viruses are much smaller, usually between 20 to 300 nanometers. Fungi can be larger, with some species forming structures that can be several millimeters in size. Overall, pathogens are microscopic and cannot be seen without a microscope.
