The correct answer is antibiotics, vaccinations, hygiene, antiseptics/disinfectants, and food preservation. These methods help prevent the spread of diseases. Antibiotics are used to treat bacterial infections, while vaccinations help build immunity against specific diseases. Practicing good hygiene, such as washing hands regularly, can prevent the transmission of pathogens. Antiseptics and disinfectants kill or inhibit the growth of microorganisms, reducing the risk of infection. Lastly, food preservation techniques, such as refrigeration or canning, help prevent the growth of bacteria and other harmful microorganisms in food.
