How to prevent infection of viral cold summary of common sense of viral cold prevention
4hw.com.cn: it is very easy to cause colds in winter. What is more afraid of is the infection caused by viral colds. For small partners with poor physical resistance, it is particularly troublesome to infect viral colds, which not only threatens the health of the surrounding and family, but also makes the condition particularly easy to repeat. So how should we prevent viral colds every day? Let's have a look!
Viral symptoms are mainly high fever, lasting for a long time, accompanied by runny nose, sneezing, sore throat and so on. The route of transmission can spread the virus into the air and infect others by sneezing, coughing and speaking. Healthy people can also get sick from using the patient's towel, washbasin or tableware.
Daily prevention of viral cold
Because there is no specific therapeutic drug for colds, and once a cold will have a certain impact on work and life, prevention is particularly important. Enhancing resistance and preventing pathogen invasion are the key to prevention. The main measures include:
(1) On weekdays, we should pay attention to physical exercise and reasonably arrange outdoor activities to adapt to the changes of environment and climate.
(2) Clothing should be appropriate and increase or decrease in time with climate change to prevent cold or overheating.
(3) Control and treat chronic diseases and correct malnutrition.
(4) Pay attention to indoor ventilation and avoid going to crowded and dirty public places.
(5) Avoid inducing factors such as overwork and drunkenness.
(6) Pay attention to personal hygiene and wash hands frequently.
Inducement and prevention of viral cold
It is generally believed that transmission through respiratory droplets is the main mode of transmission of the virus. However, in recent years, some studies have new ideas on its inducement. The following situations are included:
(1) The 'touched' cold virus can survive for about 1 hour on the handkerchief. The temperature of the hand is very suitable for its survival, so that its survival time on the hand can be as long as 70 hours. When cold patients blow their nose or sneeze, they stick the virus to their hands, and then transfer the virus to places that people often contact through their hands, such as door handles, tables and chairs, telephones, etc. healthy people are very vulnerable to infection when they contact these hands or items that pollute the virus.
(2) Many experts at home and abroad have found that bad eating habits are closely related to colds. Eating too much high salt food can reduce saliva secretion, increase oral mucosal edema, congestion and virus, easily cause upper respiratory tract infection, and finally lead to the onset of cold. Eating too much high sugar food can consume nutrients such as water and vitamins in the body, cause dry mouth, low immunity, and then induce a cold. Eating too much high-fat diet, such as cream, meat and broth, can reduce the anti-virus ability of immune cells and easily cause colds. In order to prevent colds, we should stay away from the 'three high' diet with high salt, high sugar and high fat.
(3) The clinical observation of 'sitting' out of the cold found that people who sit in the office, soak in Internet cafes, sit playing mahjong and have less activities have a 2-3 times higher chance of catching a cold than normal people. It is reported that when the only TV Tower in an island country can not work normally, the treatment rate of children with colds has decreased significantly. After investigation and research, in the past, children used to surround the TV all day and have little activity. Now they go back to nature to do outdoor activities, which restores their resistance to the virus.
(4) Some toothbrushes are sealed with a cylinder. Toothbrushes are often in a wet state, and germs are easy to breed. People who can't cure a cold for a long time, in addition to their weak physique and poor resistance, are repeatedly infected because of the gum wound caused by the virus by brushing their teeth.
(5) According to expert research, taking drugs indiscriminately can lead to colds. Pharmacological experiments and clinical studies show that many drugs, especially sulfonamides, antibiotics, anti tuberculosis drugs, anti-cancer drugs, and even antipyretic and analgesic drugs (such as paracetamol) have different degrees of inhibition on the immune system. Regular use of these drugs can reduce the disease resistance of the human body, so that people are easy to catch a cold.
(6) 'worry' comes out of the cold. As the saying goes, 'worry makes your head white', which shows the impact of worry on the human body. Sentimental people tend to reduce their immune function, their ability to kill pathogenic microorganisms and the level of interferon. Accordingly, the respiratory defense function decreases, so that the cold virus can take advantage of it. According to the statistics of foreign scientific research data, people who often worry or worry often suffer from colds 3 ~ 5 times more than normal cheerful people.
(7) Smoking is harmful to health, especially to the organs of the respiratory system. Long term smoking also affects the endocrine system and the metabolism of the whole body, so as to inhibit the immune function and make people easy to catch a cold.
(8) The key to prevent colds is to keep the indoor air clean. When the doors and windows are closed and there is no pollution source such as carbon monoxide, the indoor air will also be polluted with the increase of the number of people and the extension of time. Often open the window, the exhaust gas discharged by the human body and the smoke in the house can float away with the circulating air, which is conducive to the prevention of colds.
Common viruses include rhinovirus, coronavirus, etc. Streptococcus pneumoniae and hemolytic streptococcus are common bacteria. The main symptoms of children with viral cold are fever, high or low body temperature, runny nose, sneezing, coughing, good spirit, loss of appetite, sometimes accompanied by vomiting and diarrhea, and very few children will have high fever convulsion. The main symptoms of children with bacterial cold are fever, especially persistent high fever, purulent runny nose, sore throat, depression, poor appetite, and febrile convulsions in some children.
