How do pathogens enter the body?

Pathogens, such as disease-causing bacteria, viruses, and fungi, can enter the body through various routes. The most common way is through inhalation, where pathogens are inhaled into the respiratory system, especially if the person comes into contact with contaminated droplets from coughing or sneezing. Ingestion is another common route, where pathogens enter the body through contaminated food or water that is consumed. Pathogens can also enter through open wounds or breaks in the skin, providing a direct entry point. Additionally, some pathogens can be transmitted through sexual contact or from mother to child during pregnancy or childbirth. It is important to maintain good hygiene practices and take necessary precautions to minimize the risk of pathogens entering the body and causing infections.
