After all the scabs fall off, people can't get the virus from them anymore!
Humans are actually the only ones who can get Smallpox.
The variola virus goes through the lytic cycle which means that the virus goes inside of a host cell and replicates. After the host cell dies, all the virus inside of the cell is released into the organism and the viruses are free to infect new host cells.
How do you know if someone has the virus?
You can tell if the person is showing symptoms, or if the virus is found in their bloodstream.
What happens if we get it?
Smallpox was eradicated but if there was another outbreak, the US has enough vaccine to protect everyone.
