life science Maturity 11-13 Next article →

A herpetic whitlow is a skin sore. It usually happens on a finger or thumb. It can also happen on toes. This sore is caused by a virus. The virus is called herpes simplex virus. We call it HSV for short. There are two types of this virus. They are HSV-1 and HSV-2.

Children often get it by sucking their thumbs. This can spread the virus from their mouth. Adults may get it from contact sports. Some workers also get it. This includes dentists and doctors. They may touch things with the virus on them.

The finger may get red and puffy. It can feel very sore. Small, clear bumps called vesicles may form. These bumps can join together. They might look cloudy. Some people may also have a fever. This can happen if the infection is bad.

The sore usually heals in two to three weeks. The bumps will dry out or burst. Most people do not get scars. The virus can stay in the body. It can hide in the nerves. This means the sore might come back. About 20 to 50 percent of people see it again.
