Eating garlic does not prevent the new coronavirus. Garlic is only a kind of food, and allicin extracted from garlic has certain antibacterial activity, but there is no research evidence to show that consumption of garlic has an inactivating effect on the new coronavirus, and consumption of garlic cannot prevent the new coronavirus infection. There is no specific method or drug to prevent the new coronavirus, but you can pay attention to the following aspects: for example, injecting the new coronavirus pneumonia vaccine, avoiding the epidemic areas and places where the population gathers, washing and disinfecting hands diligently and paying attention to hand hygiene, paying attention to rest, strengthening nutrition, strengthening exercise to improve the immune system, going out to wear masks, and strengthening the indoor ventilation and other measures. Prevention of the new coronavirus need to talk about science, do not blindly listen to methods that are not based on science. Tip: “New coronavirus pneumonia and new coronavirus pneumonia” mentioned in this article have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
