5 Symptoms of Measles

Fever. The disease begins with a sharp rise in temperature to 38-40 degrees. Virus particles enter the blood flow and interact with lymphocytes. Lymphocytes release substances that serve as a signal to the hypothalamus (part of the brain) to increase a body temperature. Fever is a mechanism that helps to create unfavorable conditions for the virus reproduction and accelerates the production of antibodies that can overcome the disease.
