Recently, there is a saying circulating in the circle of friends and WeChat group that lactobacillin tablets have therapeutic effect on new coronavirus. However, the effect of lactacystin is similar to yogurt, which may have a certain effect on intestinal flora, but it can’t do anything for the virus. There is no specific medication for novel coronavirus, and symptomatic support is the main treatment. Novel coronavirus pneumonia can present as mild, moderate and severe. For mild to moderate patients, because the viral infection is self-limiting, only isolation and symptomatic treatment are required.
