A.        Ventilation is better than incense

　　Physical air disinfection can be divided into two types of disinfection, physical disinfection and chemical disinfection. Physical disinfection includes ultraviolet light irradiation, electrostatic adsorption and air filtration methods. Chemical disinfection includes fumigation with disinfectants, such as fumigation or spray peracetic acid, ultra-low volume spray disinfectants with chlorine, and peracetic acid, and disinfection by the chemical factors that immediately come from the use of some disinfection equipment, and could do air disinfect by the ozone.

　　Some people think that fumigation lactic acid, vinegar fumigation and incense can effectively kill the coronavirus, which has no scientific proof. Talking about the sanitizing effect, the best method is to let the window and door open wide, keep ventilation; this could be simple and affordable. However, Hopeople should not directly face the ventilated place to avoid cold. When there are more guests in the family, disinfect by peracetic acid fumigation or ozone after the guests leave and no one is in the house.

　　Second, proper concentration is better than higher of the sterile water

　　Some people think the higher concentration the sterile water is, the better the effect is. Actually, if the sterile water concentration is too high, it is easy to form a protective layer in the surface of the virus, thus will not kill germs. Furthermore, high concentrations sterile water stimulates people's oral, nasal mucosa for a long time, lead the respiratory damage easily, vulnerable to pathogens, and could not meet the purpose of preventing respiratory tract disease. At the same time, the chlorine volatile rapidly, and has strong corrosive, the excessive concentration will simulate the body, causing poisoning. Therefore,do according to the instruction when use the chemical method, produce the sterile water in proper concentration, and do ventilation after disinfection. Mastered the correct way of disinfection method, long-term disinfection will not damage health.

　　Third, have meals separately is better than that together

　　Previously, at the time of gathering of friends and relatives, many people like to have dinner outside in restaurants, lively, and also facilitate the exchange of feelings.However, in order to ensure the health, sanitation, it is better to have meal separately. This way could we avoid SARS infection in the meal; it could show respect to others and our own lives safety. If do not want to cook, can order meals from restaurants, heated by microwave. It is I also necessary to pay attention not to eat and drinking too much, and have too much fat, be regulated, and mainly light.

　　Fourth, keep pets’ health is better than abandon them

　　Now the scientists suspected that the "SARS virus came from animals". This is just a suspicion, yet to be confirmed. However, as some people heard that the SARS virus may come from animals, they abandon their pets promptly, this practice is not necessary, and it is wrong. Pets been abandoned in the street, has no one tube, would be unsanitary, and more easily to be transmitted diseases, but maintain your pet sanitation is very important. Because many viruses, such as AIDS, bird flu, is spread from animals to humans.If your cats and dogs like to walk in the community, "go to see neighbors", the owners must enhance preventive awareness, and control their freedom, and use the specialized "bath liquid" to have the family pets get regularly bathe, this could do sterilization as well as disinfection.

　　Fifth, telling the truth to the children is better than avoid speaking clearly

　　Some parents believe that there is no need or should not tell their children about the situation of SARS, to avoid causing them be unnecessary fear. In fact, avoid telling clearly to the children the topic of SARS is not advisable. For the information is so developed in the modern society, it is almost impossible to get children had no contact with SARS information, if do not directly tell the children, would make the child to mistrust, causing unnecessary psychological pressure. Parents and teachers should frankly tell the children about the danger of the existed SARS. Through the introduction of SARS, adult could teach the children some knowledge of health, for example, some children usually do not like to wash their hands, but now talk about the importance of washing hands to these children can be played effective roles. In addition, children can learn some knowledge in the fields of science, medicine and the natural, and could have the feelings of the strength of science. In the child's growth process, SARS is a important test, let the children participate and learn, at the same time feel love and respect in the struggle against SARS, they will become stronger, and growth healthier in sudden incidents.
