Preventing children's diseases is a comprehensive solution to maintain the health of the future generation children are more sensitive and vulnerable to diseases than adults due to their physical, mental and environmental characteristics. Their immune system is not yet fully formed and in many cases they still do not have enough experience to deal with pathogens. Therefore, prevention of children's diseases is one of the most important responsibilities of the family, doctors and society, which helps to maintain the health and improve the quality of life of children. The importance of disease prevention in children Children's diseases include a wide range of infectious, respiratory, digestive, skin and chronic diseases, some of which can have long-term effects on a child's health and development. Preventable diseases such as measles, diphtheria, tetanus, and polio have been greatly reduced by vaccination, but viral diseases, allergies, and nutritional problems are still common. Timely prevention prevents serious complications, hospitalization and even death of children. Methods of preventing children's diseases ### 1. Regular and timely vaccination Vaccines play a key role in creating immunity and preventing infectious diseases in children. According to the national vaccination program, the child must receive necessary vaccines at a certain age so that the immune system can be protected against pathogens. Some of the most important vaccines are: - Measles, Mumps and Rubella (MMR) vaccine - Polio vaccine - Tetanus vaccine - Hepatitis B vaccine - Influenza vaccine In addition to individual protection, vaccination also reduces the transmission of diseases in society. ### 2. Healthy nutrition and strengthening the immune system proper nutrition is the basis of healthy growth and resistance to diseases. Children's nutrition should contain all the major food groups including proteins, carbohydrates, healthy fats, vitamins and minerals. Breast milk is recommended as the best source of nutrition until at least six months of age because it contains natural antibodies that strengthen the baby's immune system. Improper nutrition can lead to malnutrition, anemia and weak immune system, which makes the child susceptible to many diseases. ### 3. Compliance with personal and environmental hygiene Personal hygiene, such as regular hand washing with soap and water, using tissue when sneezing and coughing, and avoiding contact with sick people are the most important principles of prevention. Children should be taught how to maintain hygiene from an early age. In the living environment, the cleanliness of the place of residence, proper ventilation, preventing the accumulation of insects and disease-carrying animals are other important factors. Using a mask in crowded spaces or during the outbreak of infectious diseases can help reduce the transmission of viruses. ### 4. Maintaining mental health and teaching healthy behaviors Children's mental health and reducing stress have an undeniable role in strengthening the immune system. The family environment should provide a safe, loving and supportive environment for the child. It is also very important to teach healthy behaviors such as avoiding contact with allergenic substances, preventing unhealthy habits such as nail biting or putting objects in the mouth. ### 5. Physical activity and adequate sleep Regular exercise improves blood circulation, strengthens muscles and improves immune system function. Children should have enough time during the day for active games and physical activity. Adequate and regular sleep helps to restore the body and increase resistance to diseases. Lack of sleep weakens the immune system and increases the risk of infections. ### 6. Prevention of environmental damage Exposure of children to cigarette smoke, air pollution, chemicals and pollutants can make their respiratory system and the whole body vulnerable. It is very important to prevent these factors, especially in the home and school environment. ### 7. Regular visits to the doctor and periodical examinations Baby examination by Dr. Mehdi Afshari helps to identify diseases early and provide timely treatment.
