Paronychia herpetic whitlow is a viral infection of the finger caused by the herpes simplex virus. It typically occurs in healthcare workers who come into contact with patients who have herpes infections or in individuals who have a weakened immune system.
The infection begins as a red, painful bump on the finger, often near the nail bed. Over time, the bump may fill with pus and develop into a blister. The blister may burst, leaving an open sore that is prone to infection. The infection can spread to other fingers or other parts of the body if not treated promptly.

Symptoms of paronychia herpetic whitlow
The symptoms of paronychia herpetic whitlow typically start with redness and pain around the nail bed, and can include:
- Tenderness and swelling around the affected area.
- Formation of fluid-filled blisters, which may appear clear or cloudy, and can be painful.
- The blister may break open, exposing the raw skin underneath, which can be painful and may bleed.
- Redness and inflammation of the surrounding skin.
- Numbness or tingling in the affected finger.
- Swollen lymph nodes in the neck or armpit, particularly if the infection spreads beyond the affected finger.
These symptoms may develop slowly or quickly, and they can vary in severity depending on the individual's immune system and the stage of the infection. In some cases, people with paronychia herpetic whitlow may also experience fever, chills, and fatigue.
It is important to seek medical attention if you suspect you have paronychia herpetic whitlow or if you develop symptoms of a finger infection, as early treatment can help prevent complications and reduce the risk of spreading the infection to other parts of the body.
Causes of paronychia herpetic whitlow
Paronychia herpetic whitlow is caused by the herpes simplex virus (HSV). This virus is highly contagious and can be spread through direct contact with a person who has an active herpes infection or by touching an object contaminated with the virus. The virus can enter the body through small cuts, breaks or cracks in the skin around the nail bed.
Certain factors can increase the risk of developing paronychia herpetic whitlow, including:
- Healthcare workers who come into contact with patients who have herpes infections, particularly those with weakened immune systems.
- People with weakened immune systems, such as those with HIV/AIDS or those undergoing chemotherapy.
- People with a history of herpes infections, as the virus, can become reactivated in the body.
Once the virus enters the body, it can remain inactive for long periods of time, and then reactivate, leading to the development of paronychia herpetic whitlow. It is important to take precautions to prevent the spread of the virus, including practising good hand hygiene and avoiding close contact with people who have active herpes infections.
Diagnosis of paronychia herpetic whitlow
The diagnosis of paronychia herpetic whitlow is typically made by a healthcare professional based on a physical examination and a discussion of symptoms and medical history. In addition, laboratory testing may be done to confirm the presence of the herpes simplex virus.
The following are some of the diagnostic methods used to diagnose paronychia herpetic whitlow:
- Physical examination of the affected finger
- Review of medical history and recent exposure to the herpes virus
- Sample collection and laboratory testing of fluid from the affected area for viral culture or polymerase chain reaction (PCR) testing to confirm the presence of the herpes simplex virus.
It is important to seek medical attention if you suspect you have paronychia herpetic whitlow or if you have symptoms of a finger infection. Other conditions, such as bacterial or fungal infections, can cause similar symptoms and may require different treatments. An accurate diagnosis is important to ensure proper treatment and prevent complications.
Treatment of paronychia herpetic whitlow
The treatment of paronychia herpetic whitlow typically involves antiviral medication to help fight the herpes simplex virus. The medication may be taken orally or applied topically to the affected area. Examples of antiviral medications that may be used to treat paronychia herpetic whitlow include acyclovir, valacyclovir, and famciclovir.
In some cases, antibiotics may also be prescribed to prevent or treat a secondary bacterial infection. Pain relievers may be recommended to help manage discomfort.
In addition to medication, self-care measures can help relieve symptoms and promote healing, such as:
- Soaking the affected finger in warm water for 15-20 minutes several times a day to reduce pain and swelling.
- Keeping the affected finger clean and dry to prevent infection.
- Applying a cold compress to the affected finger to reduce swelling and pain.
- Avoiding touching or picking at the affected area to prevent the further spread of the virus.
- Wearing gloves or a protective covering over the affected finger reduces the risk of spreading the infection to others.
It is important to follow the treatment plan recommended by your healthcare professional and to take all medication as directed, even if symptoms improve. If the infection does not improve or worsens despite treatment, seek medical attention as soon as possible to prevent complications.
Paronychia herpetic whitlow is a painful infection that can be caused by the herpes simplex virus. It is important to seek prompt medical attention if you suspect you have this infection, as early treatment can help prevent complications.
By following proper hand hygiene procedures and taking steps to protect yourself from the herpes virus, you can reduce your risk of developing this condition.
