Abstract: During the treatment of the coronavirus disease 2019 in 2020, scientists have found out that better effect of antiviral treatment was associated with selenium and folic acid levels in human. The results indicated that the diet with high levels of selenium and folate can effectively enhance human immune function and to cope with the impact of viral diseases. One of the main tasks of plant biofortification is to ensure the intake of selenium and folate effectively through diet. However, there were few reports on the combined biofortification of selenium and folate. This paper reviewed the ways and mechanisms of selenium and folic acid in the treatment of antiviral, as well as the application prospects of selenium and folate in plants, so as to provide the theoretical support for improving nutritional quality and creating crops, vegetables and fruits rich in selenium and folate.
