Transmission of disease Photo

The microbes enter the human body through various entries also known as the portal of entry which includes the respiratory tract, gastrointestinal tract, mucous membrane, and skin. A carrier is an individual capable of transmitting a pathogen without displaying symptoms of the disease. The transmission of pathogens is by two modes active carrier and passive carrier. The pathogen must have a reservoir before transmitting the disease also a pathogen may have more than one living reservoir. The transmission of microbes into the host body can be through different means such as direct contact, indirect contact, droplet contact, vector transmission, fecal/oral route and acquired infection.
