After the beginning of autumn, the drizzle drizzle also caused the temperature to drop by several degrees instantly; coupled with the temperature difference between morning and evening, "Be careful of catching a cold" is a spoken word for middle-aged people to care about their children and the elderly! Many people think that the virus will invade after the body catches a cold, but in fact, the relationship between the two is not the case.
Is a cold caught a cold? Poor resistance. No matter how much you wear, it will be ineffective.
Whenever the weather gets cold, many people start to 'ah chi...', which seems to be particularly prone to colds. The reason is that when the external environment becomes cold, the virus is more active. When you do not take sufficient protective measures and your resistance is not strong enough, even if you wear too much and keep warm, the virus will still easily invade the body and cause a cold.
In addition to colds, the flu also makes many people very worried. What is the difference between a general cold and an influenza ? Although influenza also has the word "cold", the severity caused by influenza is much greater than that of ordinary colds; the main difference lies in the different "pathogens" of the two, that is, the different types of viruses.
Influenza symptoms are different from general colds. High fever and general soreness are signs.
Generally, there are many types of viruses that cause colds, including rhinovirus , respiratory tract fusion virus, etc., and there are endless discussions; and there are three main types of influenza virus , type A, type B, and type C, among which type A and type B are particularly prone to pandemics.
General cold symptoms usually include cough, runny nose, etc.; the symptoms of influenza are more serious than colds, and are characterized by high fever, which is 39 or 40 degrees, and there will be sore throat, , whole body aches, or fatigue. On the contrary, the symptoms of cough, runny nose, etc. are less obvious.
Severe influenza is common in elderly people, children, and patients with high three-high
The most worrying thing is that once the influenza occurs, it will become severe influenza, which may be fatal. There may be two possible sources of influenza complications, one is caused by the influenza virus itself, and the other is caused by bacterial invasion after the virus destroys the respiratory tract and resistance; common severe influenza symptoms include pneumonia, encephalitis, myocarditis, , etc.
People with poor resistance, such as children under 5 years old, elderly people over 65 years old, patients with chronic diseases such as three highs or diabetes, patients with heart disease, patients with kidney disease, patients with lung disease (especially obstructive pulmonary disease), and people who smoke frequently are high-risk groups who are prone to severe influenza.
