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 do norovirus and rotavirus form when they cluster together?

• Cells

• Vesicles

• Bacteria

• Proteins

What is the role of the protective membrane surrounding the virus clusters?

• To help the virus clusters replicate

• To make the virus clusters visible to the immune system

• To protect the virus clusters from the immune system

• To destroy the virus clusters

How do viruses within the vesicles replicate?

• By absorbing nutrients from the host

• By merging with other viruses

• By forming more virus particles inside the membrane

• By splitting into two

What happens to the vesicles as they pass through the immune system?

• They become inactive

• They separate and infect a single cell with multiple viruses

• They remain intact and do not infect any cells

• They are destroyed by the immune system

Where do the vesicles release the viruses to initiate infection?

• In the intestine

• In the bloodstream

• In the lungs

• In the liver
