Killing viruses through high fever is not scientific and has no scientific basis. The causes of high fever are as follows: 1. The most common reason is that bacteria and viruses breed in the body, causing reactions of antigen and antibody complexes, and also releasing inflammatory factors in the body, such as bradykinin, leukotrienes, and tumor necrosis factor. All these substances move up the central neuronal tuning point of body temperature, which leads to high fever. So high fever is not able to kill the virus, but the body’s defensive response. 2, high fever to kill the virus is not scientific, viral infections can lead to high fever, such as viral pneumonia, viral gastroenteritis, and even the emergence of viral urticaria, there will be high fever, so high fever to kill the virus is not advisable.
