Since entering winter, the proportion of patients with colds in the emergency clinic has increased significantly, especially the elderly and children, and I found that many of them were families coming together to see the cold during the night shift in the emergency department of pediatrics. In the pediatrics to see the child and then go to the internal medicine department to see their own, why are so many people infected? Experts say there are several reasons. First: the cold virus in the door handle can survive 2 days Some researchers have found that the cold virus can usually survive two days or even longer, and the study also found that some patients often contact with the area, such as refrigerator doors and door handles have a 40% chance of retaining the cold virus. Ear, nose and throat experts have done a study confirming that after a guest with a cold leaves a hotel, a large number of cold viruses remain on the remote control of the TV set and the power switch in the hotel room. The next guest who stays in the room may get a cold as a result. This means that if you have a person with a cold in your home, try not to touch door handles, remote controls, and other items that are frequently used by multiple people. Other items in this category include light switches, bathroom faucets, telephones, and so on. Second: do not have a cold close contact with people family members who have a cold, must try to avoid close contact with the child, such as kissing the child’s face, and the child mouth-to-mouth talk and so on. Third: keep warm over the head also want to suffer from colds Why are infants and young children prone to colds? Why are babies and young children prone to colds? The reason is that children are young and their resistance is weak. However, it is more often caused by human beings, such as keeping warm too much. Recently, the weather has started to get cold, some young parents think that their children are too young to be afraid of the cold, so they put on coats and jackets for their children and keep them too warm. In fact, this is a good intention to do a bad thing, but more likely to cause the child to catch a cold, the child would have been active, metabolism is also fast, too many clothes too thick, the child will be easy to sweat. Sweat becomes cold, wet and wet on the child’s skin, it is easy to catch a cold. Therefore, parents should be appropriate according to climate change for the child to increase or decrease the clothes, rather than the more thicker the more insurance. Fourth: “Hand washing” is the best prevention method Hands are one of the main ways of respiratory virus transmission. To prevent influenza, it is imperative that you wash your hands frequently. You should try to wash your hands with warm or hot water, and use soap, not only to coat your fingers and palms, but also the lower part of your nails, around your wrists and between your fingers. Rub your hands against each other long enough before washing them with water. When office colleagues or family members have a cold, the telephone, door knob, remote control and towels that they touch may be contaminated with influenza virus because, in addition to the spread of influenza virus through the air, saliva and droplets, the things touched by people with colds are also important infectious substances, and the virus can survive on these objects for several hours. So develop the good habit of hand washing, you can reduce the virus in the hands of the time to stay, to avoid infection. Fifth: open the window, drink more water The air does not circulate, there is no fresh air replacement, if there is a cold, the number of viruses in the room must be quite a lot, in such an environment, the virus is easy to be breathed into the body. Open the windows from time to time to let the air flow and disperse the virus to minimize the chance of spreading the cold. Drinking plenty of water helps to protect the skin mucous membrane barrier and also helps the body to flush out metabolic wastes and toxins.
