Viruses and Bacteria
Explanation:
Bacteria are single-celled, prokaryotic microorganisms that exist in abundance in both living hosts and in all areas of the planet. By their nature, they can be either "good" or "bad" for the health of plants, humans, and other animals that come into contact with them. A virus is acellular (has no cell structure) and requires a living host to survive; it causes illness in its host, which causes an immune response. Bacteria are alive, while scientists are not yet sure if viruses are living or nonliving; in general, they are considered to be nonliving.
Infections caused by harmful bacteria can almost always be cured with antibiotics. While some viruses can be vaccinated against, most, such as HIV and the viruses which cause the common cold, are incurable, even if their symptoms can be treated, meaning the living host must have a strong enough immune system to survive the infection.

General
Speed and Velocity are similar in that they both measure d/t (distance over time), however, speed only measures d/t. Velocity is d/t+D (direction).
Examples
Your speed could be 50m/h, your velocity could be 50m/h north.
