What are the types of diabetes?

Diabetes is a disease in which your body either can't produce insulin or can't properly use the insulin it produces. Insulin is a hormone produced by your pancreas. There are three major types of diabetes. Type 2 diabetes is the most common diagnosis, followed by type 1 diabetes. Gestational diabetes occurs during pregnancy, and is usually temporary. In addition, prediabetes is another important diagnosis that indicates an elevated risk of developing diabetes. Type 1 diabetes is an autoimmune disease and is also known as insulin-dependent diabetes. People with type 1 diabetes aren't able to produce their own insulin (and can't regulate their blood sugar) because their body is attacking the pancreas. People with type 1 need to inject insulin or use an insulin pump to ensure their bodies have the right amount of insulin. People with type 2 diabetes can't properly use the insulin made by their bodies, or their bodies aren't able to produce enough insulin. Type 2 diabetes can sometimes be managed with healthy eating and regular exercise alone, but may also require medications or insulin therapy.

How are viruses made?

A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein. Viruses are capable of latching onto host cells and getting inside them. The virus then uses the host cell’s machinery to replicate its own genetic material. Once replication has been completed the virus particles leave the host by either budding or bursting out of the cell (lysis).
