What is a viral fever?

In medical terminology, an increase in body temperature due to viral infection is called viral fever. A real virus that causes fever may or may not be identifiable. Viral fever can be accompanied by other symptoms and symptoms such as runny nose, red eyes, malaise, irritability, joint and muscle pain, enlarged lymph nodes and rash. The viral fever is usually solved after three to seven days and is considered benign and restrictive. However, it can cause complications, especially among very young, very old and immunocompromised. Some viruses spread through direct inoculation or sexual contact. Viruses can affect a certain organ and medical symptoms can locate to this organ. For example, Adenovirus and Rinovirus affect the upper resporine, causing the upper respiratory tract infection, while Rotavirus and Norovirus affect the gastrointestinal tract, causing gastroenteritis or diarrhea. After the virus is located locally, it is transported to the blood or lymph andFinally, they are afraid of the immune system.

Viral fever occurs because substances such as prostaglandins, interleukin-1 (IL-1) and tumor necrosis (TNF) are released by activated lymphocytes and macrophages. Fever occurs when these substances stimulate the hypothalamus to reset the body temperature settings at a higher level. Paracetamol, aspirin and non -steroidal anti -inflammatory drugs are able to reduce fever because they prevent prostaglandin synthesis.

In addition, the viral fever plays an important role in helping to reduce viral infection. It is assumed that with an increase in body temperature with special proteins called heat shock proteins (HSP) are activated to strengthen lymphocyte reaction to the infection. Fever between 38 to 39 ° C (100.4 to 102.2 ° Fahrenheita) is classified as a low -degree fever and between 39 to 40 degrees Celsius (102.2 and 104 degrees Fahrenheit) is classified as a fever. The main fever docIt throws when body temperature exceeds 40 degrees Celsius (104 degrees Fahrenheit). Hyperpyrexia occurs when body temperature reaches 42 degrees Celsius (107.6 degrees Fahrenheit) and above.

viral fever may be beneficial, but fever classified as a slight degree or high degree is a reason for concern. The patient should be given a temperature reduction measures such as the use of antipyretic medicines and a cold bath. In particular, hyperpyrexia is considered to be medical emergency because it reaches the limit of what is compatible with life.
