Get to know the HPV virus
What is HPV? How many types are there?
HPV is a group of viruses called human papillomavirus which infects epithelial tissue, causing disorders around genital and anal areas. HPV can be found in both men and women. There are over 100 strands, of which types 16 and 18 are the most harmful.
How is it transmitted and spread?
HPV can be infected through sexual activities involving the vagina, anus or mouth. The virus spread through wounds, scratches on the skin or skin-to-skin contact, as well as through contacts with contaminated items from infected patient. An alarming fact is that pregnant moms who have HPV can pass it on to their baby while giving birth. Thus, infection can occur through direct contact or from sexual activities. Usually, people who have HPV are asymptomatic, therefore, they may unknowingly infect others.
Symptoms of HPV
Most people with HPV are asymptomatic because the immune system can eliminate the virus before it progresses to a wart. Each wart will be different due to type of viruses:
- Common warts – small blisters that grow on the hands, fingers, elbows. Their colors include beige, white, pink, or light brown. The most common sites are hands, fingers and elbows. They may seem harmless but can be painful and the affected area may bleed easily.
- Flat warts – darker in color and look like smooth, flattened or pimply bumps. Any body part can be affected, but legs are the most common site for women, beard for men and face for children.
- Genital warts – cauliflower-like appearance which affects the genital and anus areas of both women and men. They are itchy but not painful.
- Plantar warts – the soles of the feet are most affected. They are hard bumps and painful when walking and standing.
