Don't spread the 'folk prescription' of epidemic prevention

        Since the outbreak of new coronavirus began to spread, various "epidemic prevention Prescriptions" have been widely spread on the Internet. Many of them even use the names of scholars and experts to write articles. This issue of "legal column" is specially for you to collect the interview contents of the media "Taiwan fact check center" received by the infectious physician of Far Eastern Memorial Hospital, so that there is no hiding of false information.

Rumor 1: the new coronavirus is not resistant to high temperature, and can't survive in the environment of 26-27 degrees, so should we drink more hot water?

Yang Jiarui section chief of Far Eastern Memorial Hospital: Although the virus is not resistant to high temperature, it will still survive when the temperature is 26-27 ℃. In addition, human body temperature will not be changed by drinking hot water, and the new coronavirus is generally infected through the respiratory mucosa, and drinking water is through the gastrointestinal tract, and there is no connection between the two.

Myth 2: the incubation period of new coronavirus is 0-24 days. Many people are asymptomatic at first, and only when they arrive at the hospital, they find that 50% of the lungs have fibrosis. In fact, as long as you can inhale at the maximum depth and close your breath for more than 10 seconds without discomfort, it means that there is no fibrosis in the lung?

Yang Jiarui section chief of Far Eastern Memorial Hospital: after three to four weeks of lung inflammation, the lung will start to fibrosis, which is a chronic process. It is said that the method mentioned is not correct. It is suggested that the public should go to the hospital for pulmonary function examination to confirm.

Myth 3: if you are infected with new coronavirus pneumonia, as long as you take sudafed, Afrin and Neti Pot on time, you can slow down the respiratory symptoms?

Liu Jiaying section chief, integrated medical department of Far Eastern Memorial Hospital: sudafed can relieve nasal obstruction, Afrin can slow down nasal obstruction and rhinorrhea, etc., to Neti Pot is a nasal washer, all of which are common over-the-counter cold drugs abroad, but have no effect on killing viruses or bacteria.

Rumor 4: when you have a cold, if you have runny nose and expectoration, can't it be new coronavirus pneumonia?

Yang Jiarui section chief of Far Eastern Memorial Hospital: the main symptoms of new coronavirus pneumonia are fever and cough, but there are still a few patients with rhinorrhea and runny nose. In order to determine whether it is infected or not, it is necessary to rely on molecular biological diagnosis, and to take samples from nasopharynx or oral cavity to detect whether there is nucleic acid of new coronavirus. In clinical diagnosis, the general physician will check whether the patient has cough, sputum, rhinorrhea and other symptoms, and then ask whether there is a tourism history of the epidemic area.

Rumor 5: put an onion in the room without peeling. There is a real influenza virus on the onion. It can be seen that the onion can absorb the virus and keep the human body healthy. And the onion that absorbs the virus will turn black in the next morning.

Yang Jiarui section chief of Far Eastern Memorial Hospital: influenza is a virus, not a bacterium. There is a mistake in this rumor. Moreover, onion has no effect of virus absorption. It should be caused by oxidative deterioration.

Rumor 6: alcohol can kill the virus in the mouth and throat. After blood absorption, it can kill the virus in the lung. So drinking a little white wine every day will help prevent the new coronavirus pneumonia?

Yang Jiarui section chief of Far Eastern Memorial Hospital: the bactericidal power of alcohol is related to the concentration, not to the total amount of drinking, and the principle of alcohol sterilization is to spray 75% alcohol to the surface of bacteria or virus, and then destroy the bacteria or virus. If it enters the human body and is absorbed by the human body, it has no disinfecting effect. It will only cause problems such as rapid heartbeat, accelerated circulation, nerve excitation, vasodilation, etc. it can not enhance immunity. If it is drunk for a long time, it will have the suspicion of alcoholism.

Myth 7: drinking salt water, black tea and Pu'er tea can resist the new coronavirus?

"Theaflavin in black tea and Puer tea can prevent coronavirus" is said by Yang Jiarui section chief of Far Eastern Memorial Hospital infection department. However, theaflavin content in black tea and Puer tea is not high enough, and has not yet been tested in clinical trials, so the effect cannot be confirmed. Although salt water gargling helps to clean the mouth and throat, the new coronavirus invades the respiratory tract of human body, and the gargle can not clean the respiratory tract, and there is no evidence that salt water helps to eliminate the new coronavirus.

Rumor 8: eating vegetarian, curry, drinking garlic water, vitamin C supplement, etc. can prevent new coronavirus pneumonia?

Yang Jiarui section chief of Far Eastern Memorial Hospital infection department: these statements are lack of research evidence at present. Some foods can only improve immunity, which does not mean they can prevent viruses.

Myth 9: hypertension patients easily infected with new coronavirus pneumonia? Can dogs and cats spread the virus?

Yang Jiarui section chief, infection department of Far Eastern Memorial Hospital: Although according to the statistics of mainland hospital, patients with chronic diseases such as hypertension, diabetes and hyperlipidemia are easy to become severe patients, it does not mean that people with hypertension are particularly vulnerable to infection. Others include: spray alcohol disinfection is easy to cause fire, cats and dogs will spread virus and other rumors, which will make people more panic, and remind everyone not to turn around the sensational news at will, and should check with experts more often, not to be the wrong leader of false news.
