Study finds stomach viruses cluster together to become more deadly

The video explains how norovirus and rotavirus form clusters called vesicles, which are protected by a membrane. This membrane allows the clusters to evade the immune system and replicate quickly. As the vesicles pass through the immune system, they reach the intestine, where they separate and infect a single cell with multiple viruses.

What happens to the virus clusters as they pass through the intestine?

Describe the process by which the virus infects a single cell.
