Preventing Diseases Through Water:
- Water is cleaned and purified at the waterworks before it reaches homes to make it safe for drinking.
- Chlorination is commonly used in cities to disinfect drinking water and remove harmful pathogens.
- Filtration systems, such as sand filters and RO systems, help remove impurities and contaminants from water.
- In small towns and villages, bleaching powder is added to common water sources, like wells, to kill germs and make the water safe.
- If there is an epidemic of diseases like gastro or jaundice, people are told to boil water before drinking to kill any harmful germs.
- Proper sewage disposal prevents contamination of water bodies and reduces the spread of waterborne diseases.
Preventing Mosquito-Borne Diseases:
- To stop diseases like malaria, we must make sure there is no stagnant water (standing water) around, as mosquitoes breed in it.
- If we cannot get rid of stagnant water, we use insecticides to kill mosquito larvae before they grow into adult mosquitoes.
- Keep surroundings clean by not letting water collect in open containers, tires, or flower pots.
- Cover water storage to stop mosquitoes from laying eggs.
- Use mosquito nets and repellents to avoid mosquito bites.
- Put small fish in ponds because they eat mosquito eggs.
- Spray insecticides to kill mosquitoes in areas where they breed.
- Tell everyone about the importance of keeping water sources clean to prevent diseases like malaria and dengue.
Quarantine for Serious Infectious Diseases:
- People with serious infectious diseases, such as tuberculosis or swine flu, are kept separate from others. This is called quarantine.
- Hospitals have special wards where only patients with infectious diseases stay to prevent the disease from spreading to others.
- The clothes and utensils used by the patient are cleaned with germicides (special chemicals that kill germs).
- People with tuberculosis collect their spit in a container with a germicide-like phenol to kill the germs.
Preventing Airborne Diseases:
- Diseases that spread through the air, like the flu, can be prevented by covering the mouth when sneezing or coughing.
- People should avoid spitting in public places to stop the spread of germs.
- If someone needs to be near someone with an infectious disease, they should wear a mask to cover their nose and mouth for protection.
- If someone in your family gets an infectious disease, it is important to inform the government health department.
- The health department will take the necessary steps to prevent the disease from spreading to other people.
