What is a whitlow?
A whitlow is a painful and highly contagious infection on the fingers caused by the herpes simplex virus. It is also known as herpetic whitlow.
There are two types of herpes simplex virus—type 1 and type 2—and both can cause herpetic whitlow. A whitlow can occur when broken skin on your finger comes in direct contact with body fluids infected with the herpes simplex virus. These body fluids may come from you or someone else.
A whitlow can cause pain, itching, redness or swelling on your fingers. Your fingers may also develop small blisters. Whitlow may be accompanied by more general symptoms, such as fever, enlarged lymph nodes or red streaking on the hands or arms. These symptoms may indicate a serious infection.
A whitlow often resolves without treatment in two to three weeks. However, your health care provider may prescribe medications to reduce symptoms such as pain or itching. If you experience frequent or severe cases of whitlow, your heath care provider may prescribe antiviral medications to prevent or limit the severity of future infections.
Whitlow is rarely associated with a serious medical condition. However, seek immediate medical care (call 911) if your whitlow, or that of someone you are with, is associated with a high fever (higher than 101 degrees Fahrenheit), confusion, or loss of consciousness for even a brief moment.
Seek prompt medical care if your whitlow is persistent, recurrent, or causes you concern.
