Actually, the most common portal of entry for pathogens is the respiratory tract, not the skin. Pathogens often enter the body through the air we breathe, in droplets from coughs or sneezes, or on dust particles. The skin, while it can be a portal of entry if it is broken or punctured, is generally quite resistant to infection thanks to its physical barrier and the presence of antimicrobial substances. Other common portals of entry include the gastrointestinal tract (through contaminated food or water) and the urogenital tract.
