About This Worksheet
Diseases are health conditions that can affect our body and may be caused by germs such as bacteria, viruses, fungi, and parasites. Some diseases are communicable, meaning they can spread from one person to another through air, water, food, direct contact, or insects. Tuberculosis (TB) is a bacterial disease that mainly affects the lungs and can spread through the air when an infected person coughs or sneezes. Influenza (flu) is a viral disease that commonly spreads through respiratory droplets and close contact. Swine flu, commonly associated with the H1N1 influenza virus, is also a respiratory infection that can spread from person to person. Bacterial diseases such as typhoid and cholera can spread through contaminated food or water. Many infectious diseases can be prevented by following simple health and hygiene practices. Washing hands regularly, drinking safe and clean water, eating properly cooked food, maintaining cleanliness, covering the mouth and nose while coughing or sneezing, and avoiding close contact with infected people can reduce the risk of infection. Vaccination is another important method of preventing several infectious diseases. The worksheet associated with this topic helps students identify different diseases, understand the germs that cause them, learn how they spread, and match each disease with appropriate preventive measures. By completing the worksheet, students can strengthen their understanding of disease prevention and develop healthy habits in everyday life.
