Rumor identification: Antibiotics cannot prevent new coronavirus infections. Rumor Analysis: 1. Antibiotics and other antibacterial agents have antibacterial or bactericidal effects, but the pathogen of new coronavirus infections is a virus. The virus does not have a cell wall, nucleases, ribosomes, all functions are dependent on the host cell to complete, therefore, antibiotics can not kill the virus. 2. Although patients infected with novel coronavirus are sometimes co-infected with bacteria, they will receive antibiotics at this time. But antibiotics need to be used under the guidance of a doctor, because the abuse of antibiotics will not only lead to strong toxic side effects and harm to the human body; but also make the bacteria resistant, and even harm the normal flora inside the body, thus allowing pathogenic bacteria to take advantage of the situation. Special Note: To date, there are no drugs specifically designed to prevent and treat novel coronavirus infections. Therefore, patients who are suspected of having a novel coronavirus infection should not take medication on their own. You should protect yourself, such as wearing a mask, and then go to a regular hospital for examination. If you are diagnosed with novel coronavirus, you should receive regular treatment under the guidance of your doctor.
