Virus is a type of noncellular organism, which is simple in structure, small in size and contains
only one kind of nucleic acid (RNA or DNA). It must be parasitized in living cells and proliferates
by replication. Viruses can infect plants or animals, which leads to many epidemic diseases, such
as the current pandemic COVID-19. Viral infectious diseases have brought serious threats to the
health of people around the world. Natural products are chemical substances that are usually produced
by living organisms and have biological or pharmacological activity. Many of these natural products
show antiviral activity. Based on the increasing importance of antiviral research, this paper focuses on
the discovery and development of antiviral natural products since 2010.
