Explosive Smallpox

Structure of a Virus

All viruses start with DNA or RNA surrounded by a protein coat called a capsid. Some viruses have a lipid membrane surrounding the capsid called an "Envelope".

What Do Viral Diseases Do In Cells

They attach themselves to the host cell that they intend on infecting, whether it's through the Lytic or the Lysogenic Cycle. In both cycles, the virus injects their viral DNA into the cell. In the Lytic cycle, which is the shorter of the two cycles, when the virus injects it's DNA into the cell, it takes over the cell, then it leaves the cell which destroys it. In the Lysogenic cycle, when the virus injects it's DNA into the cell, it incorporates it's viral DNA with the cells DNA, so that when the cell reproduces it will contain the viral DNA. In both cycles, when the viruses are finished with one cell, they seek to find another cell to infect.

Three differently shaped viruses.

Viruses are not living. They are not cellular. They depend on host cells to reproduce, they cannot move, and they don't eat.

Just how small are viruses?

Viruses are very small. They are much smaller than even the bacteria and animal cells that they infect. A Tobacco Mosaic Virus is 10 nanometers, and could fit about 100 of itself in an animal cell.

How do they reproduce?

Viruses cannot reproduce on their own, so they depend on their host cells. When they inject their DNA into the cell, it divides and more viruses are created.


-There are two types of viruses for small pox. One is Variola major and the other one is Variola minor.

-Symptoms: smallpox usually appear 12 to 14 days after you're infected. If you are infected, you will have a high fever, a headache, overall discomfort, severe fatigue and back pain, and possibly vomiting. Few days later, flat red spots will begin to grow on the face and then spread all around the body.

-Spreads: smallpox are very contagious . A person can get smallpox just by standing next to someone who has it. smallpox is spread when a person breathes in and out.

-Fatal?: Smallpox is a fatal disease because some can die from it. This virus is like a bomb and it explodes many of the cell that is in the body. When millions of cells are damaged, it can ruin one entire organ, and you fall apart from the inside.

-Treatments: There is no proven treatment for smallpox. Someone that is a victim of smallpox is isolated and they go through the treatments of replacing fluid lost from fever and skin breakdown. Antibiotics are needed for secondary skin infections. The infected person is kept in isolation for 17 days until the scab falls off.

-Prevent: To prevent yourself from getting smallpox, you can stay alarmed by listening to new and see if smallpox is roaming around your community. Stay away from people who have red rashes on their body. Also wash hands thoroughly and regularly, and avoid touching the mouth, eyes, and nose.
