The cold we usually say refers to the common cold, commonly known as cold, is a type of acute upper respiratory tract infections, often caused by viral infections, manifested as nasal symptoms, such as sneezing, nasal congestion, watery nasal discharge, but also may be manifested as a cough, dry throat, pharyngeal itching, 2-3 days after the nasal mucus becomes thick, may be accompanied by a sore throat, headache, tearing, hoarseness, loss of taste, chills, fever, general body aches and pains, malaise and so on, usually takes 5-7 days to recover from. Generally, it takes 5-7 days to recover, and the condition of those with complications can be prolonged. Clinicians often diagnose acute upper respiratory tract infections in addition to the common cold as a clinical type, but also includes acute viral pharyngolaryngitis, acute herpetic pharyngitis, acute pharyngoconjunctivitis and acute pharyngotonsillitis, manifesting different degrees of damage to specific areas. The current misunderstanding of the cold are: 1, “cold is influenza” influenza is referred to as influenza, is an acute respiratory infectious disease caused by pandemic influenza virus, and the common cold is different. Performance of high fever, headache, fatigue, conjunctivitis and generalized muscle aches and pains and other obvious symptoms, while the respiratory tract nasal congestion and runny nose and other symptoms are mild. Mainly through contact and air droplet transmission, can be distributed, sometimes small-scale epidemics, when the virus mutation can appear large-scale outbreaks. 2, “hang a drip on the fast” This is the consensus of many Wenzhou people, but also many people think that the results of personal experience, the reason for this, most patients may be sick early in the oral medication to see if it is not good enough to go to the infusion, and then the symptoms soon disappeared, in fact, this time the improvement is not a credit to the infusion, but the time to recovery! The general view is that for most patients, the medical practitioner will be able to help them to recover! It is generally believed that, for most patients, medical personnel are encouraged to drink more boiled water in order to play the effect of infusion, for those who eat significantly less due to colds, high fever and a lot of sweating, and those who have related underlying diseases, medical personnel will consider discretionary infusion. 3, “colds must use anti-inflammatory drugs” because most of the colds are caused by viral infections, so in the early stage of the antibiotic class of drugs (that is, the so-called folk anti-inflammatory drugs), but the choice of antiviral drugs, or more vitamin C to increase the ability of antiviral, and only when there is a white blood cell elevation, pharyngeal pus, coughing up yellow sputum, and other bacterial infections, then use antibiotics. Antibiotics should only be used when bacterial infections such as elevated white blood cells, pus in the throat and yellow sputum are present. 4, “a high body temperature with fever-reducing drugs” temperature is the body’s resistance to foreign disease-causing viral or bacterial infection of a defensive method, therefore, should not be artificially interrupted this defense, only in the body temperature of more than 39 ° C or the patient more than a certain temperature and have a very clear sense of discomfort before the discretion to lower the temperature, lowering the temperature can be used to wet compresses, ice and oral medications such as Tylenol. Tylenol and other oral medications, the effect is not obvious when the use of intramuscular injection cooling drugs, try to avoid the use of Anacin and other drugs with side effects. At the same time, we should recognize that a cold temperature is not once or twice with the drug can be reduced, it needs a 3-5 days of the process, do not because of 1-3 days of repeated rise and fall of the body temperature and make a fuss. 5, “the last time is also similar symptoms, the doctor said it is a cold, this time should also be a cold” Many diseases such as measles, polio, etc., in the early stages of the disease is manifested as a cold with similar symptoms, the doctor to see the patient from the current symptoms and signs of the discovery or exclusion of a variety of clues to determine or exclude the diagnosis of pneumonia, meningitis, myocarditis, etc., and in accordance with the condition of the appropriate treatment. The doctor should find or exclude various clues from the patient’s symptoms and signs to determine or rule out the diagnosis of pneumonia, meningitis, myocarditis, etc., and carry out the corresponding examination according to the condition. Therefore, don’t be self-righteous to think that you are suffering from cold because of the similar symptoms; the patient should explain to the doctor the onset of the disease, the symptoms, the treatments and the effects in a detailed and methodical manner, so the doctor will be able to diagnose and examine the disease faster and more accurate. 6. “Cold viruses are airborne, so hand hygiene doesn’t matter” It is true that cold viruses are airborne, but they can also be spread by contaminated hands and utensils, so hand hygiene is very important for people who suffer from colds and those who come into contact with them. For the most part, the common cold is not a serious illness, but there are many variables that go into a person with the common cold, and there are many more things to look for in a person diagnosed with the common cold: 1. Does the headache persist as the body temperature drops? One of the main differential diseases of the cold is meningitis, the patient performance in the body temperature drop after the headache still persists, so for patients with the cold, if the headache does not reduce or aggravate after the temperature drop should go to the hospital again, the cerebrospinal fluid examination to clarify the diagnosis. 2.After 3-5 days of treatment, is the body temperature not decreasing and there is obvious cough and pus sputum? Another complication of cold is pneumonia, which is prone to occur in people with especially low immunity. If respiratory symptoms such as cough and purulent sputum worsen significantly after 3-5 days of treatment, patients with colds should be seen again and X-rays should be taken to determine whether pneumonia exists. 3. Are there any new symptoms, such as black stools and difficulty in breathing? Cold symptoms are not very specific and can be an early manifestation of many diseases, therefore, patients should seek medical attention when symptoms different from those at the beginning appear.
