Answer:
When the propagation of an infectious disease gets reduced, people stop getting their children or themselves getting vaccinated for the infectious disease.
But what we forget is somebody out there might be an asymptomatic carrier of the disease and can spread the disease. As a result, if many people are not vaccinated for the particular disease, then there might be an outbreak of the infectious disease again and it can be deadly.
Not everyone has the exact same number of cells in their body, but we all have trillions. I hope this helps cx
All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. Unlike bacteria, most viruses do cause disease, and they're quite specific about the cells they attack.
