Problems solved by technology

[0003] At present, some western medicines are commonly used to prevent and treat influenza virus. Western medicine is mainly symptomatic treatment, one component is aimed at one symptom, and western medicine often has some side effects. For example, oseltamivir can convert the esterase in the intestinal tract into active metabolites, thereby Interfering with the spread of the virus, but not suitable for patients who have symptoms of lower respiratory tract infection; Peramivir, as the only intravenous neuraminidase inhibitor, is more effective than other neuraminidase inhibitors, and is more effective than oral neuraminidase inhibitors.
