HPV is actually a group of very common viruses that affect the skin and cells which line your body cavities.
There are around 100 different types, and it’s thought that around 8 in 10 people will be infected with the virus in their lifetime. Most people won’t even know they have it, but some types of HPV in some people can go on to cause problems.
Those problems can include things like genital warts, and some kinds of cancer.
