How long does a low-grade fever last?

For the human body, there will be no inexplicable fever symptoms. The occurrence of fever indicates that the human immune system is continuing to work, which is often caused by some viral or bacterial infection. In the early stages of AIDS, a low-grade fever often occurs, which indicates that the body's immune system is trying its best to eliminate the virus, resulting in such low-grade fever symptoms. The duration of a low-grade fever can also vary, from a few weeks to longer.

In fact, most people's symptoms will last for about 1 to 4 weeks, and generally will subside within 2 months. If the situation is serious, treatment is required. If you use fever-reducing medication indiscriminately, you may make it more difficult for the immune system to defeat invaders. However, high body temperature can also cause damage to the body by changing the body's enzymes. Perhaps, this paragraph has confused you.

1. You may wonder:

Is human "fever" a disease or an immune response? The correct answer is: immune response. Relatively speaking, the human body's immune cells are afraid of cold but not heat. Coldness can make immune cells inflexible, while appropriate temperatures allow the cells to move freely. To use a vivid analogy: if a person stays in a cold place for a while, his hands, feet and even the whole body will become stiff. Why is this so? Because the human body is made up of cells. When the cells are exposed to the cold, their activity is greatly reduced, so people become slow and stiff.

2. High temperature antibacterial

After the human body is invaded by bacteria and HIV, our immune system will instinctively and automatically adjust the body's mechanisms to create a high-temperature environment to facilitate our own immune cells to act flexibly to eliminate the enemy. At the same time, the high temperature environment inhibits the reproduction of the enemy.

Of course, when there is no enemy invasion, our body temperature is normal, and immune cells do not need to be blindly overly tense and active. They only need to warm up when the enemy comes. Now, do you understand what "fever" means?

3. It requires energy.

This energy is not an antibiotic, not a hormone, not a diuretic, not alcohol. Instead, it is an immune-nutrition food rich in phytonutrients, antioxidants, and polysaccharides. Many patients with early AIDS symptoms have persistent low-grade fever. In order to help the early AIDS symptoms subside, the patient's nutrition needs to be strengthened.

Testing can be done, but there is no guarantee that there will be enough antibodies during this period to detect HIV. Because the current AIDS test detects viral antibodies, the time it takes to produce these antibodies is called the "window period", and it can be detected after the window period. Testing can be started 2 weeks after infection in order to gradually relieve the pressure. You can rest assured if the result is negative after 6 weeks. A very small number of people may need 3 months. It is recommended to have a follow-up check after 3 months. Of course, if you feel too stressed and need to relieve stress, testing once a week is also feasible. You can decide the time for HIV testing based on your own situation.
