STI- HPV

What causes Human Papillomavirus (HPV)?

When a papillomavirus infects a human.


How can HPV be transmitted?

HPV is typically transmitted through sexual contact. It can be transmitted through all the same ways that any other STI can be transmitted. Through sexual activity, mixing of blood from an infected person.


What are the signs and symptoms?

Genital HPV usually has no symptoms, unless it is a type that causes genital warts. Genital warts may appear within weeks or months after contact with a partner who has HPV. More rarely, genital warts may show up years after exposure.

Most people will never know they have HPV because they have no symptoms and the body's immune system causes the virus to become inactive. In about 90% of cases, the body's immune system clears the HPV infection within 2 years. This is true of both high-risk and low-risk HPV types. A small number of people with HPV will have the virus for a longer time. These people can develop cell changes that over many years may lead to cervical or other genital or anal cancers.

What are the ways to treat it?

HPV has no known cure. The virus will usually be cleared from the body with the help of the body's immune system within 2 years. However, HPV can lead to other types of cancer. However, these types of cancer can be treated.

How can HPV be avoided?

The only way is to abstain from all sexual activity. It is usually not possible to know who infected persons are. However, HPV infections are so common that most ways of preventing other STIs do not guarantee that you won't get it. They will reduce the risk though.
