Preventing communicable diseases requires good hygiene, vaccination, and healthy habits. Washing hands regularly with soap reduces the spread of germs. Covering your mouth while coughing or sneezing prevents infections from spreading. Vaccinations protect against diseases like measles, flu, and COVID-19. Safe food practices, clean drinking water, and proper sanitation help prevent illnesses. Avoiding close contact with sick individuals minimizes exposure. A strong immune system, maintained through a balanced diet, exercise, and adequate sleep, helps fight infections. Using insect repellents and protective clothing prevents mosquito-borne diseases. Simple precautions and awareness can safeguard health, reducing the risk of disease outbreaks.
