Colds are a common acute upper respiratory infectious disease with high incidence. Perhaps it is too ordinary and common, so that the cold has become the most common discomfort in the various forms of medical treatment, and it is also a hot search term in the online retrieval. But it is not that there are "colds" when sneezing, runny nose, etc. are "cold"! Today, I will tell you the things about colds.

The symptoms of colds include sneezing, cough, nasal congestion, runny nose, sore throat, chest tightness, etc. Most of them are not fever, or they only show low fever (37.3 to 38 degrees Celsius), and the symptoms of this disease do not durate for a long time, often with self -limit Essence Because the above symptoms are easily confused with diseases such as influenza, pneumonia, sinusitis, and asthma, when the patient is medical, the doctor asked "where is uncomfortable" or "what symptoms", and the patient is not recommended to answer "I just have a cold" "I have a cold for a month", but should describe the symptoms, such as "the throat has been painful for a few days", "runny nose, sneezing, and cough for a while" and so on.

Why is a person easy to catch a cold

Ordinary colds are usually caused by virus infections. You must know that many viruses can enter the nasal cavity, oral cavity, throat, etc., causing symptoms of related parts, such as nasal congestion, runny nose, and throat pain. These viruses are very rich, such as rhinovirus, respiratory tract hyperthythral virus, adenovirus, and so on. Because these viruses are very popular and the human body lacks effective vaccines and antibodies to resist the virus, the probability of being infected is high. At the same time, winter and spring are the "preferences" survival climate of the above viruses. In the low temperature state, the virus survives longer, plus less ventilation of windows in winter, and less air circulation, resulting in the virus cannot spread and dilute. Therefore, it seems to seem to be "Colds are frozen" "Suddenly cold and love a cold."

Regardless of the public and medical workers, they need to understand the differences between ordinary colds and popular colds (referred to as influenza) and new crown virus infections. Influenza and new coronal virus infection is a strong infectious disease, so rapid identification in the early stage will help the control of the disease and curb the spread of social scope. Influenza virus infection usually has more than 38.3 degrees Celsius, accompanied by severe sore throat and muscle soreness. In severe cases, there will be obvious dyspnea and hemoptysis. Lares by taste or loss of smell.

Who needs to pay more attention to colds

There are really fewer cases of severe colds, but special groups need to be treated with caution. For example, elderly people over 65 years old, children under 5 years of age, maternal mothers, chronic basic diseases (such as slow obstruction, asthma, bronchial dilatation disease , Patients with malignant tumors, uremia, cirrhosis, diabetes, etc.). If the above -mentioned population has long cough or obvious dyspnea, hemoptysis, and fever does not retreat, you need to seek medical treatment as soon as possible.

If the child has the following situations, please take a medical treatment as soon as possible: blurred consciousness or no response, difficulty breathing or exhaustion.

If the child has the following situations, please take him to the general outpatient medical treatment or contact the community medical staff: 1. Lost taste or smell, or do not want to eat food that usual consumes usual. 2. Severe sore throat. 3. Refuse to drink anything for a long time. 4. Age less than 4 months. 5. Hot and abnormal behavior. 6. The cough lasts for more than 2 weeks and does not improve or worsen. 7. Nasal congestion or runny nose worse or no improvement after 10 days. 8. The eyes are red or there are yellow viscous substances. 9. Ear pain, pulling the ears or other signs of infection in the ear.

Special people should pay attention to cold or cold -related symptoms, and inform the doctors' basic symptoms in time. They are neither over anxiety nor blindly confident. This is a rational approach.

Is there a way to prevent colds

First of all, no medicine can prevent colds. For example, probiotics, vitamins (including vitamin C, vitamin D, vitamin E, etc.), the existing high -quality scientific research has not proved that additional supplementation of such drugs can reduce the incidence of upper respiratory tract infection.

Secondly, if it is an upper respiratory tract infection, such as influenza or new coronal virus infection, vaccination is the most effective measure, especially to protect key groups and clearly affect the severe role.

Finally, learn to wash your hands correctly and to wash your hands frequently. Drums and secretions containing viruses and enter the nasal cavity and oral cavity through the respiratory tract. The upper respiratory tract infection caused by the respiratory tract is more common. Correctly washing hands can reduce the risk of infection and protect key groups. Washing hands with soap and water often helps to prevent the spread of other diseases such as influenza and new coronal virus infections.

It is necessary to remind everyone that drinking more hot water, juice, and soup when you are sick can make up for liquid loss caused by runny nose or fever sweating. Keeping indoor ventilation and keeping indoor humidity can relieve nasal congestion and smooth breathing. Keeping regular schedules and ensuring sufficient sleep is a good way to improve cold symptoms.
