Transmission vectors

Transmission vectors are methods or routes through which a disease-causing agent, like a virus or bacteria, spreads from one person or organism to another. Think of them as carriers or vehicles, such as insects (like mosquitoes), contaminated water, or objects (like doorknobs), that transfer pathogens. When a vector interacts with an infected individual and then contacts another person, it can transmit the disease. Understanding transmission vectors is essential for controlling and preventing the spread of illnesses by targeting those specific routes or carriers.
