请给出一个传染病通用模板，准备一个一分半钟的英语口语topic

Hello everyone, today I'd like to talk to you about infectious diseases. Infectious diseases are caused by microorganisms such as bacteria, viruses, fungi, and parasites. They are spread from one person to another through direct contact, through the air, or through contaminated food and water.

One of the most common infectious diseases is the flu, which is caused by the influenza virus. Symptoms include fever, cough, and body aches. Another common infectious disease is tuberculosis, which is caused by the bacterium Mycobacterium tuberculosis. This disease primarily affects the lungs and can be spread through the air when an infected person coughs or sneezes.

Other infectious diseases include HIV/AIDS, malaria, and hepatitis. Prevention is key to controlling the spread of infectious diseases, and measures such as vaccination, hand washing, and safe sex practices can help reduce the risk of infection.

In conclusion, infectious diseases are a global health concern and it is important to educate ourselves on the prevention and treatment of these diseases. Thank you for listening.
