Causes of Viral Infection Rash
Viral fever with rash occurs because the immune system reacts to the virus or to the agent acting on skin cells.
For example, when infected with the measles virus, the immune system detects foreign antigens moving in the circulatory system and releases chemicals to destroy them. However, these substances also cause inflammation of the skin, leading to a rash.
Shingles, on the other hand, is related to the reactivation of the chickenpox virus lying dormant in the nerves. Once there, the virus begins to travel down the nerves and into the skin. Then they multiply here and a shingles rash will form.

- Measles
- Chicken pox
- Rubella
The route of infection is usually through contact with respiratory secretions in the air when talking directly or with secretions from the nose and throat of an infected person. Note that people who have been infected with the virus can pass it on to others before the rash appears
However, some other viral diseases are transmitted by vectors such as mosquitoes, ticks, and fleas, such as the Dengue virus.
