After entering the host cell by fusion, the viral genome is immediately translated into new viral proteins. Following genome replication in the cytoplasm, new virions are assembled in the cytoplasm and continuously bud from the host to spread the infection. Based on this information, describe the basic characteristics of this virus.

Question

Quizplus · Accepted Answer

The description of the virus entering the host cell by fusion and budding from the host to spread the infection indicates that it is an enveloped virus. The immediate translation of the viral genome into new viral proteins suggests that the genome acts as mRNA, characteristic of a positive-sense RNA virus. Therefore, the correct answer is an enveloped virus with a single-stranded positive-sense RNA genome.
