The symptoms of a cold include sneezing, coughing, nasal congestion, runny nose, sore throat, chest tightness, etc. Most of them have no fever or only show low fever (37.3-38 degrees Celsius). Moreover, the symptoms of this disease do not last long and are often self-limiting. .
Common colds are usually caused by viral infections. You must know that many viruses can enter the nasal cavity, mouth, throat, etc., causing symptoms in related parts, such as nasal congestion, runny nose, sore throat, etc. There are many types of these viruses, such as rhinovirus, respiratory syncytial virus, adenovirus, etc. Because these viruses are very prevalent and the human body lacks effective vaccines and antibodies to resist the viruses, the probability of being infected is very high.
At the same time, winter and spring are the preferred living climates of the above-mentioned viruses. At low temperatures, the virus survives longer. In addition, there are fewer windows for ventilation in winter and less air circulation, which prevents the virus from spreading and diluting. Therefore, it seems “Colds are caused by colds” and “sometimes cold and sometimes love colds”.
Common colds are usually caused by viral infections and are less likely to cause serious illness, but special groups need to be treated with caution. For example, elderly people over 65 years old, children under 5 years old, pregnant women, patients with chronic underlying diseases (such as COPD, asthma, bronchiectasis, malignant tumors, uremia, cirrhosis, diabetes, etc.).
If the above-mentioned people have a long-term cough or have obvious symptoms such as difficulty breathing, hemoptysis, or persistent fever, they need to seek medical attention as soon as possible.
Get medical help as soon as possible if your child is confused or unresponsive, has trouble breathing or is labored to breathe.
If your child has the following conditions, please see a professional as soon as possible:
1. Loss of taste or smell, or unwillingness to eat usual foods.
2. Severe sore throat.
3. Refusing to drink anything for a long time.
4. Age is less than 4 months.
5. Fever and abnormal behavior.
6. The cough lasts for more than 2 weeks without getting better or worse.
7. Nasal congestion or runny nose worsens or does not improve after 10 days.
8. Eyes are red or secrete yellow sticky substance.
9. Ear pain, pulling on the ear, or other signs of infection such as ear suppuration.
first,No medicine can prevent colds. For example, existing high-quality scientific research on probiotics and vitamins (including vitamin C, vitamin D, vitamin E, etc.) has not proven that additional supplementation of such drugs can reduce the incidence of upper respiratory tract infections.
Secondly, if it is an upper respiratory tract infection with a known cause, such as influenza, vaccination is the most effective measure, especially to protect key groups, and has a clear effect on reducing severity.
Finally, learn to wash your hands correctly and frequently. Upper respiratory tract infections are common due to contact with virus-containing droplets and secretions that enter the nose and mouth through the respiratory tract. Proper hand washing can reduce the risk of infection and protect key groups. Washing your hands frequently with soap and water can help prevent the spread of other illnesses such as the flu.
What needs to be specially reminded is that drinking more hot water, juice, and soup when you are sick can make up for the fluid loss caused by runny nose or fever and sweating. Maintaining indoor ventilation and maintaining indoor humidity can relieve nasal congestion and make breathing easier. Maintaining a regular schedule and getting enough sleep are good ways to improve cold symptoms.
