Explain any three preventive measures to control microbial infections.
✓

Answer

Three preventive measures to control microbial infections are as follows:
  1. Avoiding contaminated food and water: Many infections are spread through contaminated food and water, e.g. cholera and jaundice. These infections can be easily prevented by avoiding contaminated food and water. One should use properly filtered and treated water for drinking and cooking. Food from roadside vendors should not be consumed.
  2. Preventing vectors: Malaria and dengue are examples of vector borne diseases. If we can check the breeding of mosquitoes in our surroundings, we can easily minimize the chances of suffering from these diseases. Mosquito repellants and mosquito nets are also effective in preventing mosquito bite.
  3. Maintaining hygiene: Maintaining personal hygiene can help us in avoiding various types of skin infections. Maintaining cleanliness in surroundings can help in avoiding many communicable diseases.
