Novel coronavirus is an infectious disease caused by novel coronavirus. According to the research results, novel coronavirus is sensitive to high temperature, 75% alcohol and ultraviolet rays.

At the high temperature of 56℃, the virus can only survive for half an hour; Novel coronavirus can also be effectively inactivated after spraying 75% alcohol; Ultraviolet radiation for 30 minutes can kill novel coronavirus.

However, no research shows that lemon can inactivate novel coronavirus. If residents are infected with novel coronavirus, they need to go to the hospital for treatment in time. They can't resist novel coronavirus by eating lemons and drinking lemonade, so as not to delay treatment.

Lemon is rich in citric acid and vitamin C, in addition to limonin, carotenoids, folic acid, vitamin B6, flavonoids and potassium. Some of these ingredients are considered to have anticancer effects, but there is no scientific experiment to prove that lemon can kill COVID-19.

Prevention and treatment of pneumonia in COVID-19 must rely on scientific and effective methods:

1, reducing opportunities for going out. Although many enterprises have resumed work now and most people have to go to work, they still try to stay at home after work and reduce going out. Never go to any crowded places, don't attend banquets, and don't attend parties.

Being able to drive a private car to work is the most ideal way to travel. If you don't have a private car, you must wear a mask and do personal protection when you take the bus or subway.

3. Wear a mask correctly when going out. Before wearing a mask, be sure to wash your hands and avoid touching the inside of the mask with your hands to avoid polluting the mask.

4, reasonable exercise, enhance physical fitness. You can choose some aerobic but not strenuous exercise at home, such as Baduanjin and Tai Ji Chuan. This is a traditional health preserving skill in China. Yoga is also a good choice.
