The correct options are 3. Up-to-date immunizations and 4. Encouraging your sick friends to hang out with you.
1. Washing hands: Washing hands is actually a preventive measure to reduce the spread of infectious diseases. It helps remove bacteria, viruses, and other pathogens from hands, limiting their transmission.
2. Practicing food safety: While practicing food safety is important to prevent foodborne illnesses, it does not directly contribute to the spread of infectious diseases.
3. Up-to-date immunizations: Immunizations help prevent the spread of infectious diseases by providing immunity to individuals. When a significant portion of the population is vaccinated, it establishes herd immunity, reducing the overall transmission of the disease.
4. Encouraging your sick friends to hang out with you: This is a behavior that can actually help spread infectious diseases. Being in close contact with sick individuals increases the risk of transmission, especially for respiratory diseases like colds, flu, and COVID-19.
So, options 3 and 4 are the correct answers.
