Common examples of communicable diseases include:

1. Influenza (Flu): Caused by the influenza virus, flu is characterized by symptoms such as fever, cough, sore throat, body aches, and fatigue. It spreads through respiratory droplets when an infected person coughs or sneezes.
2. HIV/AIDS: Human immunodeficiency virus (HIV) attacks the immune system, leading to acquired immunodeficiency syndrome (AIDS). HIV is transmitted through unprotected sexual intercourse, sharing needles, or exposure to infected blood or bodily fluids.
3. Tuberculosis (TB): TB is caused by the bacterium Mycobacterium tuberculosis and primarily affects the lungs. It spreads through the air when an infected person coughs or sneezes, releasing bacteria-containing droplets.
4. Malaria: Malaria is a mosquito-borne disease caused by parasites of the Plasmodium genus. Symptoms include fever, chills, sweats, headache, and body aches. It is transmitted through the bite of infected Anopheles mosquitoes.
5. Hepatitis: Hepatitis is a group of viral infections (hepatitis A, B, C, D, and E) that affect the liver. Each type is caused by a different virus and can be transmitted through various routes, such as contaminated food or water (hepatitis A), blood or bodily fluids (hepatitis B and C), or sexual contact.
6. Zika Virus: Zika virus is primarily transmitted through the bite of infected Aedes mosquitoes. In pregnant women, Zika virus infection can cause birth defects such as microcephaly in newborns.
7. Ebola Virus Disease: Ebola virus disease (EVD) is a severe, often fatal illness caused by the Ebola virus. It spreads through direct contact with the blood, body fluids, or tissues of infected animals or people.
