👉 Channels of infection are the pathways through which pathogens, such as bacteria, viruses, fungi, and parasites, enter the body and cause disease. These channels include the respiratory tract (airways), gastrointestinal tract (mouth, stomach, intestines), urinary tract, skin, and mother-to-child transmission routes during pregnancy or childbirth. Each channel represents a potential route for pathogens to invade host tissues and multiply, leading to infection. For example, respiratory droplets can spread viruses like influenza through the air, while contaminated food or water can transmit pathogens via the gastrointestinal tract. Understanding these channels is crucial for implementing effective prevention and control measures, such as hand hygiene, vaccination, and sanitation practices, to reduce the risk of infection.
