Low grade fever (37.2°C – 37.8°C or 99°F - 100°F) is a symptoms of Rubella. Fever is one of the body's defense mechanisms against infection, as the heat kills off microorganisms causing the disease.  When the body’s immune system senses foreign bodies, pyrogens (substances that cause fever) are released and travel to the hypothalamus (part of the brain which regulates body temperature). The pyrogens now bind to the receptors in the hypothalamus and the body’s temperature starts to rise, resulting in fever. When you are suffering from enlarged lymph nodes, the back of the neck, behind the ears and the base of the skull is tender and a lump can be felt. This is the hallmark of rubella.  Lymph nodes help the body fight infection by sending out disease-fighting cells and compounds and carrying white blood cells around the body. The lymph nodes themselves are small, bean-shaped glands that are distributed in different parts of the body such as the neck, groin and armpit. Viruses, bacteria and other foreign bodies are trapped in the lymph nodes (causing the swelling) and are destroyed by lymphocytes, which are special white blood cells. One of the main symptoms of rubella is an itchy rash that typically begins on the face and spreads rapidly to trunk and extremities.  At the end of the 2nd day, the rash begins to fade in the order that it appeared and by the 3rd day the rash has usually disappears. The medical term used to describe this type of rash is maculopapular - which is a combination of both flat, red patches and raised red bumps. Rubella infection triggers the occurrence of headaches, as the body struggles to fight the infection. However, it's not entirely clear why the pain signals causing the headache are triggered in the first place. Rubella infection sometimes alters a person's normal eating habits of. When higher body temperatures occur (above 98.6 degree F) the link between a person's taste buds and the brain stops working, leading to a loss of taste. Without a sense of taste, people tend to lost their appetites. With rubella, the lining of the eyelids and eyeballs sometimes becomes inflamed. This happens as a result of the same bacterial emboli (free flowing blood clot) that causes the maculopapular rash. Conjunctivitis results in inflamed eyelids and eyeballs. Whenever rubella infection is present, an aching joint pain can usually be felt. This is due to the secretion of inflammatory chemicals by the immune system, which causes muscles and joints to swell. Pain receptors in these muscles and joints then send pain signals to the brain, causing an aching sensation. Due to the presence of the rubella infection, a runny nose may occur. A runny nose keeps germs, dirt, pollen and bacteria from getting into your lungs by stopping them in your nose. When you blow your nose, the germs, dirt, bacteria and other microorganisms trapped in the mucus are expelled.
