Warts are viral infections of the Human Papillomavirus (HPV) family. The condition is a result of the virus coming in close contact with the skin. Warts mostly appear on damaged skin where the virus can easily penetrate it and cause infection. You stand at a higher risk of infection if you come in close contact with an infected person or have a weak immune system. Generally, warts aren’t life-threatening , but they are a sore sight for eyes, highly contagious and at times, they can also be painful. However, they are not cancerous. Common warts, plantar warts, and genital warts are some of the types of warts that infect people.

What are common warts?

What-are-common-wartsCaused by the Human Papillomavirus, common warts are a widespread variant of the wart, also known as Verruca Vulgaris. Though they can be found elsewhere in several cases, such warts commonly appear on hands, fingers, cuticles and beneath the fingernails.

Common warts are round, grainy, rough, and slightly raised from the skin’s surface. They can be transmitted to any other area of the body and even to a healthy person through touch or other forms of direct contact. After the virus has infected the site, it usually takes around two-six months for warts to develop and appear on the skin. Common warts usually disappear within six-18 months and do not require any treatment. However, people prefer to take medical assistance when home remedies don’t work.

What causes common warts?

What-causes-common-wartsThe HPV is the leading cause for most wart outbreaks. The common strains responsible for causing common warts are HPV1, HPV2, HPV3 and HPV 4. These are non-cancerous, but can make a weak immune system their host. People with inadequate nutrition, high stress levels are often direct victims of HPV.

What are the symptoms of common warts?

What-are-the-symptoms-of-common-wartsPeople often confuse common warts with corns as they have similar symptoms. But the difference is that corns aren’t caused by a virus and aren’t infectious. The following are the common symptoms of warts:

  • Small, round, grainy, and hard lumps on the surface of the skin
  • Clotted blood vessels
  • Rough to touch
  • White, pink, or flesh-colored
  • Painful

What are the risk factors of common warts?

Children or young adults are more prone to contract the infection as their immunity is not as strong as that of regular adults. At times, the genetic make-up or a compromised immune system makes certain people more vulnerable to the infection. AIDS and diabetes patients, or those who have had organ transplants are at a higher risk as well.

How can you treat common warts?

There are several ways to treat common warts. The primary goal is to knock out the warts completely and stimulate a stronger immune system to fight the virus. While treating warts, people often opt for self-treatment using salicylic acid as it’s the least painful or a home remedy. But this is usually not enough to get rid of warts. So, depending on the severity of the warts, experts suggest patients to go for other treatments like cryotherapy, laser surgery, or other medications.

•  Salicylic acid

Salicylic-acidSalicylic acid is available in the form creams/ointment, patch, or gel. This treatment helps in getting rid of warts as it peels off layers of the skin and also helps to shrink the wart. However, the salicylic acid could also harm healthy skin cells around the wart, so caution must be practised by the patient.

•  Duct tape

Duct-tapeA duct tape is applied on the wart for around six days. After six days, the infected area is soaked in water, and the dead tissue is plucked out using sterile forceps or emery board.

•  Cryotherapy

CryotherapyThis treatment is carried out by applying liquid nitrogen to the wart, which forms a blister under and around the wart. The dead tissue comes off a week later. The treatment has a few drawbacks, including pain or discoloration of the skin, and is not recommended for children.

•  Surgery/curettage

•  Laser surgery

Laser-surgeryIf none of the treatments work, a laser beam is used to remove the wart. The pulsed-dye laser treatment injects the tiny blood vessels, and the infected tissue eventually dies.

How can you prevent common warts?

How-can-you-prevent-common-wartsAs warts spread through contact, here are few precautions that can reduce the chances of either contracting warts or spreading them:

  • Avoid direct/close contact with an infected person
  • Maintain good hygiene
  • Avoid biting nails as warts usually occur in areas with broken skin
  • Avoid using the same nail clipper and nail file on your warts. This can contaminate healthy skin and nails
