Steps to follow:


The first thing to understand if you want to know what are the causes of warts, is that warts are caused by the human papilloma virus, the virus responsible for causing these skin growths. There are 70 different strains of this virus that cause the skin cells to multiply rapidly, resulting in growths on the skin. They aren't malignant but can be painful and highly contagious. Different strains of the virus cause different variations of the disease, from plantar warts (foot warts) to genital warts, and flat warts.


Normally, an outbreak of warts is experienced when you have had a weakened immune system or have been in poor health. This can make it more likely for you to catch the virus and, once you have it, may make it more likely for them to appear.

HPV is a virus for which there is no cure. Once in your body, you probably have it for life. It can cause warts to appear any time when your immune system is weakened. In some cases, warts only appear one year after HPV infection, and in other cases, the virus remains in the body without ever making an appearance.

Warts are highly contagious and are spread through skin contact. Foot warts are commonly caught in gym showers, where the virus can live due to the warm, moist environment.

On a separate note, genital warts are transmitted through genital contact. Many people with genital warts do not know that they have them as they are often asymptomatic, especially in a woman, who can have warts on her cervix or in the vulva without ever knowing. For men, warts appear on the tip or shaft of the penis, making them more noticeable. It is possible to spread genital HPV and warts to other areas, like mouth, throat and hands, during oral sex.

It is important to mention that although condoms offer some protection from genital warts, they are not 100% effective, as they still allow for some skin-to-skin contact.


In short, the reason behind the causes of warts is coming into contact with HPV, the virus that causes these skin growths to appear. The main reason for catching this virus is due to improper protective measures and having a temporarily weakened immune system. This is why it is important to strengthen it in order to avoid catching this virus.


You can strengthen your immune system through a proper food and a healthy lifestyle; in other words, a balanced diet and regular exercise. In this OneHowto article we show you how to boost your immune system.
