When winter arrives, the weather is cold, and it’s time for colds and flu. Today I’ll talk to you about cold and flu tips. What is a cold? Cold is the common cold, commonly known as “cold”. It is a common respiratory disease, caused by viruses or bacteria in the human nose and throat to produce an acute inflammatory response. It is often characterized by nasal congestion, runny nose, sneezing, dry and painful throat, headache, chills, general malaise, and generally low or no fever. 2 to 3 days later, the nasal discharge may gradually become light yellow and sticky-purulent. If the lesion progresses to the lower respiratory tract, symptoms such as hoarseness and cough will appear. If no complications arise, the condition will improve in about a week. What is the difference between a cold and influenza? Influenza is short for influenza. Although the two names are similar, their pathogens and disease characteristics are different. Influenza is an acute respiratory infection caused by the influenza virus. Influenza has a rapid onset and often presents with chills, chills, fever, and symptoms such as headache, generalized aches and pains, fatigue, dry throat, sore throat, cough, cough, and runny nose. In general, flu patients have more severe systemic symptoms and their condition is more serious than that of the common cold. They need to go to the hospital for active diagnosis and treatment. What should I pay attention to when I have the flu? First of all, rest well and do not work with illness. Some friends think it is a small cold and hold on to work, which results in aggravation and complications, which is not worth the loss. Secondly, it is better to go to the hospital to see a doctor for examination and diagnosis, especially in the high season of flu, which needs to be distinguished from influenza. Because the severity of the two diseases, and treatment are different. Third, it is not advisable to take more cold medicine, some people have a cold to buy some cold medicine to eat, or even eat two kinds of cold medicine at the same time, which is not only unhelpful to cure the disease, there will be many side effects. Cold medicine is mainly to alleviate the symptoms of the cold, and can not kill bacteria and viruses, is not the cure, so cold medicine should not take more. Fourth, do not blindly use antibacterial. Most of the upper sense is caused by viruses such as rhinovirus, the use of cephalosporins and other antibacterial agents is ineffective. Fifth, do not superstitiously infusion. Infusion, also commonly known as “hanging saline”. In the general impression, infusion can make the disease “get well faster”, and even some doctors will say so. But the cold is a self-healing disease, no matter what treatment measures are taken, it will not heal immediately, for the general population, the cold can heal itself in about a week. So for the cold this disease generally does not need intravenous fluids. Sixth, special groups of people should pay attention to the cold. Special groups mainly refer to the elderly, children, maternity, and chronic diseases such as chronic obstructive pulmonary disease, coronary heart disease, diabetes. For this group of people need to be alert to the complications caused by the cold, after the cold need to promptly seek medical advice. It is best not to take medication on your own.
