The weather in Guangzhou is really changeable. I caught a cold yesterday, and I feel dizzy and have a high fever today. There should be no big problem!

Cold and fever are a causal relationship, and "feeling" means feeling, feeling; "Rash" refers to "uncomfortable symptoms", such as stuffy nose, runny nose, dizziness, sore throat, tears and fever. Fever is also a symptom after a cold.

Causes of colds and fever:

1. Whole body fever-Every fever of human body is caused by some virus and bacteria. In order to protect itself, the body will raise its body temperature to cooperate with immune cells-white blood cells to destroy viruses and bacteria. Bacteria entering our bodies are generally only suitable for survival at constant temperature, and all living things (including viruses and bacteria) are not easy to survive in high temperature environment. The extreme temperature of all life on the earth is about 42 degrees. At this temperature, the tolerance time of each living species is different, and this tolerance time is proportional to the volume of the species. At the same high temperature, the larger the volume, the longer the endurance time, which is related to the speed of heat transfer. Volume, medical disinfection measures, only high temperature disinfection is the most thorough. Some regulations, such as high-pressure disinfection of medical devices, strictly stipulate tens of minutes or even hours, which is a waste of resources. It is estimated that no microorganism, including viruses and bacteria, can tolerate 1 minute at the high temperature of 90- 100 degrees on the earth.

2. Inflammatory fever-major physical trauma and organ inflammation may lead to bacterial invasion and cause fever.

3. Repeated fever-if you change your place of residence frequently, you will have a greater chance to meet different kinds of viruses and bacteria, and you will have the opportunity to have repeated fever; If it is a fixed activity place, it is basically caused by the same kind of bacteria, indicating that the body does not have the immunity of this virus and bacteria.

Everything has advantages and disadvantages. In order to kill bacteria and viruses to raise body temperature, it will inevitably lead to our discomfort, but "discomfort" is much more important than killing viruses. For example, for the treatment of cancer, there are drugs specially used to raise body temperature.

Treatment:

For a general fever, if you take medicine as soon as you have a fever, both bacteria and immune cells will be killed at the same time, and immune cells will not have a chance to identify bacteria. Once you encounter the same bacteria in the future (there are more opportunities to encounter this kind of bacteria), you will also have a fever. This is what we call decreased immunity (which pathogen immunity refers to). If this fever can be tolerated, that's the best. In the hot season, use physical cooling. If the climate is not hot, there is no need to cool down. Whether to treat depends mainly on the patient's mental state. If not, it must be treated.

For inflammatory fever, it is best to treat it because it is an "abnormal" virus invasion.

Treatment:

1. Oral drugs-low efficacy. Because it is absorbed in the stomach first, the range of effective components entering the blood is about 10-30%. Considering the safety of the stomach and other organs, the dosage of oral drugs is very low, which is why many people take medicine for about a week or even longer to recover. In fact, not all drugs are derived from.

2. Infusion drugs-high efficacy, directly into the blood to kill bacteria and viruses, no ineffective absorption link, as long as the bacteria and viruses are within the scope of drug killing, as long as the dosage is appropriate, very uncomfortable patients can feel comfortable even after infusion, which shows that the drugs have played a role, as long as they are symptomatic, they can be cured by general infusion 1-2 times. At present, infusion therapy generally uses broad-spectrum antibacterial drugs, which can produce many known viruses and bacteria. The discovery of a new virus is what we often call an "epidemic". The "several generations of drugs" formed by antibacterial drugs are all based on the discovery of viruses, and the types of viruses are also increasing.
