Is viral Urticaria caused by the Urticaria virus?
Today we are going to talk about Viral urticaria . Urticaria is a skin rash notable for pale red, raised, itchy wheals or bumps. It is usually caused by allergic reactions, however there are many non-allergic causes.
A large number of people think viral urticaria or urticaria virus is a specific disease. Its not, however some viral infections for instance, acute viral infection, can cause acute urticaria.

Urticaria is a skin rash notable for pale red, raised, itchy wheals, or bumps. It is usually caused by allergic reactions; however, there are many non-allergic causes. Many people think viral urticaria or urticaria virus is a specific disease, but it is not. However, some viral infections, such as an acute viral infection can cause acute urticaria. It is more closely linked to hepatitis, especially hepatitis B and C, which can occasionally induce urticarial vasculitis orhypocomplementemic urticarial vasculitis, but this is probably related more to vasculitis than to true urticaria or viral urticaria.
Most cases of urticaria have an unknown cause, while others are due to an autoimmune disorder. There is a small number of urticaria cases that are caused by other factors, which include friction, pressure, temperature extremes, exercise, and sunlight.
Hepatitis has a close relationship with urticaria due to different viral infections. Acute urticaria is frequently observed in the prodromic stage of hepatitis A as well as hepatitis B and sometimes in hepatitis C. Urticaria is considered one of the pre-icteric symptoms of viral hepatitis and is related to immune-complex deposits. Therefore, urticaria can also be associated with other common disorders, such as arthritis and headache. However, there are many patients with viral hepatitis who do not show any signs of acute or any other form or urticaria.
The case with chronic urticaria is different and quite confusing. There is no convincing evidence in which the hepatitis virus causes chronic urticaria. A recent controlled study has revealed that there is no link between chronic urticaria and hepatitis C. In the case of hepatitis B, not much data is available and there is still a need for research to be carried out. Systematic hepatitis virus investigations in patients suffering from chronic urticaria are usually quite expensive. Hepatitis B or C can occasionally induce urticarial vasculitis, but this is probably related more to vasculitis than to true urticaria.
