What's to know about herpetic whitlow? Herpetic whitlow results from infection with the herpes simplex virus. It can occur in adults and children. The main symptom is a painful wound on the index finger or thumb, though it can also develop on the toe. Other symptoms may follow. Here, learn about risk factors, home care, and treatments for herpetic whitlow. Read now
Herpes “triggers” (determining exactly what leads to an outbreak) are highly individual, but with time, many people learn to recognize, and sometimes avoid, factors that seem to reactivate HSV in their own bodies. Illness, poor diet, emotional or physical stress, friction in the genital area, prolonged exposure to ultraviolet light (commonly for oral herpes, such as a beach trip or skiing weekend), surgical trauma, and steroidal medication (such as asthma treatment) may trigger a herpes outbreak.
If not treated immediately, it has potential spread to other parts of the body. Being highly contagious in nature it gets readily transmitted by sharing utensils, clothes, and toothbrush. Maintaining sexual contact, kissing and touching also leads to the spread of virus. It is likely to spread more when the virus is present with physical outbursts. It is less contagious if the virus is present without any outward physical signs.
Varicella-zoster is transmitted though the mucosa of the respiratory system, specifically the upper respiratory tract, or the conjunctiva of the eye. Initial replication takes place in the regional lymph nodes, and then the virus spreads and replication begins in the liver and spleen. The virus is then transported to the skin where the rash develops. The incubation period of varicella is about 10 to 21 days.
Laboratory testing is often used to confirm a diagnosis of genital herpes. Laboratory tests include culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction to test for presence of viral DNA. Although these procedures produce highly sensitive and specific diagnoses, their high costs and time constraints discourage their regular use in clinical practice.
Jamie*, 29, is HSV-positive and contracted herpes from her husband. But, she explains, “He only had one outbreak when he was young and that was it. So he didn't realize what it was.” Jamie was infected three years into their relationship simply because he had outbreaks that infrequently. She says, “I was worried he had cheated on me, but then found similar stories online, and our outbreak patterns underscore that what happened is very possible.”
The herpes virus can be shed from an infected person even when there are no lesions visible. So caution is important. Some may wish to take the daily prophylactic oral drug Valtrex (an antiviral oral medication) to help cut down on shedding. Herpes can also be transmitted on any skin: fingers, lips, etc. Depending on sexual practices, herpes simplex can be transferred to genitals and or buttocks from the lips of someone who has fever blisters. Honesty between partners is very important so these issues can be discussed openly.
After exposure to the virus, many people experience a so called primary infection which is typically associated with sores on or around the genitals or the anus. During a primary infection some people experience pain in the groins or a mild fever. Not all infected individuals experience a primary infection or show any symptoms at all, but they can still pass the disease on to other people.
A 2004 study in the New England Journal of Medicine found that suppressive therapy decreases the risk of HSV-2 transmission from symptomatic, infected partners to uninfected partners by 48%. So “the risk of transmission is significantly reduced, but cannot be eliminated even with suppressive therapy,” Johnston explains, and she stresses that the virus can be passed along even without signs or symptoms.
