STDs, or sexually-transmitted diseases, are infections that are contracted and spread through sexual contact. There are different types of STDs today, and they are caused by different things.

 

1. Chlamydia is a common STD among young people. It is more likely to infect females than males. It is caused by bacterium known as Chlamydia trachomatis. It is ranked number one in Canada's list of most prevalent STDs.

 

2. Hepatitis B is an STD that attacks the liver. It is caused by the Hepatitis B virus. It does not have a cure, but it can be prevented by getting a Hepatitis B vaccine.


3. Gonorrhea is caused by the bacterium Neisseria gonorrhea. It is the number two most common STD in many countries, and it is very prevalent among teenagers and young adults. 


4. HIV, or the Human Immunodeficiency Virus, is a virus-caused STD that can infect anyone. It has no cure, and those diagnosed with this infection are given treatment that can slow down or control the spread of the virus around the body. If not detected and treated right away, it can progress to AIDS, which is the last stage of HIV and is fatal.


5. Syphilis is caused by bacteria. It was a lot more widespread a few decades ago, but it is still very common in some parts of the world today. 


6. Genital herpes is caused by a virus that can live inside your body for your entire lifetime. It can cause sores or lesions on the mouth, genitals, and other parts of the body.
