What is dry cough and fever?

In modern society, people's daily life rhythm is relatively fast. Many people with low physical fitness will suffer from diseases due to many factors in life. Dry cough and fever is a very common disease. Many patients do not know the cause of their own illness after they develop this disease. Many people do not understand the symptoms of this disease. So, what is dry cough and fever?

First, what is the disease of dry cough and fever? There are many reasons for fever, which can be clinically divided into infectious and non-infectious, with infectious causes being more common. Infectious fever Infections caused by various pathogens (bacteria, viruses, fungi, parasites, etc.) can cause fever. Non-infectious fever (1) Absorption of necrotic substances: such as postoperative tissue damage, internal bleeding, myocardial infarction, cancer, etc.; antigen-antibody reaction: such as rheumatic fever, drug fever, connective tissue disease, etc.; endocrine and metabolic diseases: such as hyperthyroidism, severe dehydration; reduced heat dissipation from the skin: such as extensive dermatitis, chronic heart failure, etc., generally low-grade fever; dysfunction of the body temperature regulation center: such as heat stroke, sleeping pill poisoning, cerebral hemorrhage, etc., manifested as high fever without sweating Autonomic dysfunction: mostly low-grade fever, accompanied by other manifestations

Second, if the fever is caused by bacterial or viral cold and it doesn't get better for a long time, go to the hospital to have a blood test to see if it is viral or bacterial, and prescribe the right medicine. I once had a high fever for a week before I got better, and I had a blood test with X-ray. I also need to pay attention to physical cooling, especially cooling of the head. You can use an ice towel to apply a cold compress. Excessive fever can easily cause convulsions and seizures. Some people's normal body temperature is also higher at night than during the day, so it is normal to have a fever at night. >Cough is mainly a respiratory disease (the most common), but it may also be caused by pleural disease, cardiovascular disease, central nervous system factors, etc. Acute pharyngitis, early stage of acute bronchitis, pleurisy, tuberculosis, mitral stenosis, primary pulmonary hypertension, interstitial pneumonia, pulmonary fibrosis, etc. can all cause dry cough.

What is dry cough and fever? Fever, also known as fever, refers to the situation where pyrogens directly act on the body temperature regulation center, dysfunction of the body temperature center, or various reasons lead to excessive heat production and reduced heat dissipation, resulting in a rise in body temperature beyond the normal range. Everyone's normal body temperature is slightly different and is affected by factors such as time, season, environment, and menstruation. It is generally believed that a fever occurs when the oral temperature is higher than 37.5°C, the axillary temperature is higher than 37°C, or the temperature difference within a day is more than 1°C. Fever is the most common clinical symptom and an important clinical manifestation in the progression of the disease. It can be seen in a variety of infectious and non-infectious diseases. However, sometimes a rise in body temperature is not necessarily caused by disease. In some cases, there may be a physiological rise in body temperature, such as strenuous exercise, premenstrual period and pregnancy, entering a high temperature environment or taking a hot bath, etc., which can make the body temperature slightly higher than usual. These can return to normal through self-regulation.
