Shingles/Herpes Zoster – Dealing it with Generic Valtrex
Shingles is an extremely painful skin rash caused by the Varicella zoster virus that causes chickenpox. In people who have had chickenpox, the virus is never cleared completely. It remains dormant in the nerve tissues and when the immune system of the body weakens, the virus re-activates and spreads along the nerve tissues to the particular area of the skin supplied by the involved nerve called a dermatome. This is also called as Herpes zoster or Zona. It also occurs more commonly in normal people. This disease is characterized by a painful skin rash with blisters, often in stripe.

Headaches, malaise and fever are considered to be the earliest symptoms of herpes zoster. These symptoms are nonspecific and it may result in wrong diagnosis. The earliest symptoms are followed by hyperesthesia, itching and burning pain. After one or two days skin rashes appear. The rashes mostly occur on the torso and also on the face eyes and other parts of the body too. Rashes starts appearing in stripe like pattern that is limited to one side the body. As the fever and general malaise continues, the rash looks like vesicular forming small blisters filled with serous exudates. These painful vesicles slowly become cloudy as they get filled with blood. It gets crust over within a week to 10 days and the crust usually falls off and the skin heals. At times after the severe blistering, the scarring and discolored skin remains. Depending on the dermatome involved the herpes zoster show additional symptoms. Keratitis, uveitis, conjunctivitis, and optic nerve palsies are the other symptoms. Shingles is contagious and can be spread from an affected person to children or adults who have not had chickenpox.
Shingles heal completely and well and so the problems are few. Sometimes the blisters formed due to shingles can be infected with bacteria and causes a bacterial infection of skin called cellulitis. If cellulitis occurs the infected area becomes reddened and firm and warm forming red streaks around the wound. In this case health care professionals should be contacted immediately. If the shingles affect the face or nose, there is a possibility it attacking the eyes which may lead to loss of vision. There are laboratory tests available to diagnose shingles. A VZV-igm antibody is detected in blood. This antibody appears only when there is chickenpox or shingles and not when the virus is dormant. Lymph collected from the blisters is tested using the polymerase chain reaction for VZV DNA, or it examined with electron microscope for virus particles. Lesions from the skin, eyes, and lung can be test with real-time PCR or with viral culture to detect VZV. Zostavax is the approved vaccine which can be used by adults aging 60 and above. The single-dose vaccines are more than 60% effective in reducing shingles. Patients with mild to moderate pain can be treated with over-the-counter analgesics like calamine lotions and to avoid pain medicine like morphine can be used. Vaccination against VZV is now available for children and so the chickenpox has been reduced. Thus it is expected that the shingles in adults will also be reduced simultaneously.
