Garlic is a healthy food that contains allicin, which has some antibacterial properties against some bacteria, but it has no effect on viruses and cannot inactivate and kill the new coronavirus, so eating garlic cannot prevent the infection of the new coronavirus. The use of garlic has not been shown to protect people from novel coronavirus infection based on epidemiological and research data. The best precautionary measures to prevent the spread of novel coronavirus infection are to reduce unnecessary travel, avoid travel to infected areas, and wear a mask when you go out. It is important to maintain good living habits and a nutritious diet, and to strengthen your resistance through proper exercise to reduce the chances of contracting the new coronavirus.
