At present, the prevention and control of the new crown pneumonia epidemic is in a critical period. Inaccurate information and rumors appear from time to time, causing confusion in the epidemic prevention and control work. So what are the misunderstandings of daily protection? Are some popular folk remedies effective? Facts have proved that many popular methods of preventing new pneumonia are not effective in preventing new coronavirus.

Rumor 1: Drinking Banlangen and cigarette vinegar can prevent new coronary pneumonia

Radix isatidis is suitable for the treatment of wind, heat, cold and other fevers, but it is unlikely to be effective against the new coronavirus. The concentration of acetic acid in fumigated vinegar is very low and cannot achieve disinfection effect.

Myth 2: "Smoking can prevent new coronary pneumonia"

Smoking not only reduces the body's resistance and increases the probability of infection, but also increases the risk of serious illness once infected.

Rumor 3: Ethanol can inactivate the virus, so heavy drinking can inactivate the new coronavirus

Alcohol cannot fight the new coronavirus. The most effective coronavirus killer is 75% medical alcohol. As for highly distilled spirits, usually between 50% and 60% alcohol concentration, there is no killing effect against the new crown. Covid-19 infection is transmitted through the respiratory tract and alcohol consumption through the digestive tract is unlikely to have an anti-coronavirus effect.

Myth 4: Taking antiviral drugs can prevent new coronary pneumonia

There is currently no evidence that antiviral drugs can prevent pneumonia in Covid-19.

Myth 5: Taking antibiotics can prevent new coronary pneumonia

Pneumonia from Covid-19 is caused by viruses and antibiotics target bacteria. Incorrect use of antibiotics for preventive purposes can increase resistance to pathogens.

Myth 6: Eating garlic can prevent new coronary pneumonia

Garlic is a health food that may have some antibacterial properties. But from the current epidemic, there is no evidence that eating garlic can prevent new coronavirus infection

Rumor 7: Wearing multi-layer masks can better prevent new coronary pneumonia

Just a mask will do. Wearing three or four will leave you breathless because air doesn't enter the nose from the front only from the side and provides no protection. In addition, there is no need to wear N95 masks. Ordinary disposable medical masks can also prevent the spread of droplets.

Myth #8: If you get the flu shot, you're less likely to get Covid-19

Influenza vaccines are mainly for influenza and do not prevent infection with the new coronavirus and may cause severe symptoms.

Rumor 9: Wearing goggles when going out can prevent infection with new coronary pneumonia

Wearing goggles is a protective measure for doctors who have direct contact with patients. Ordinary people do not need to wear goggles when going out.

Myth 10: Gargling with salt water can prevent new coronary pneumonia

Gargle with salt water to help cleanse the mouth and throat and help relieve throat inflammation. But the new coronavirus will attack the respiratory tract and gargle cannot clean the respiratory tract. At present, there is no research to show that normal saline can kill the new coronavirus.

Rumor 11: Spraying alcohol all over the body will kill the new coronavirus.

Spraying alcohol all over your body does not kill viruses that have already entered your body. Spraying may cause damage to clothing or mucous membranes such as eyes and mouth. Alcohol can be used to disinfect various surfaces according to appropriate recommendations. Improper spraying of alcohol may also cause a fire.

Rumor 12: Ultraviolet rays can kill the new coronavirus.

UV lamps should not be used to disinfect hands or other skin areas as UV radiation may damage the skin.

Rumor 13: Hand dryers will kill the new coronavirus

Hand dryers are not effective in killing the new coronavirus. It should only be used to dry off the water left over after washing your hands.

Rumor 14: Taking a hot bath can prevent new coronary pneumonia

A hot bath does not prevent COVID-19. The normal body temperature of a person is 36.5 ~ 36.5 regardless of the temperature of the bath or shower between 37 degrees Celsius. In fact, taking a hot bath when the water temperature is too high can cause harm to the body and may cause burns.

Myth 15: Exposure to sunlight or temperatures above 25 degrees Celsius can prevent catching the new coronavirus.

No matter how sunny or hot the weather is, people can be infected with the new coronavirus. Cases have also been reported in countries with hot weather.
