PANDEMIC DISEASES
Diseases are a natural part of life on earth. If there were no diseases, the population would grow too quickly, and there would not be enough food or other resources, so in a way, diseases are natural ways of keeping the Earth in balance. But sometimes they spread very quickly and kill large numbers of people. For example, in 1918, an outbreak of the flu across the world, killing over 25 million people only in six months. Such terrible outbreaks of a diseases are called pandemics.
Pandemics happen when a diseases changes in a way that our bodies are not prepared to fight. In 1918, a new type of flu virus appeared. Our bodies had no way to fight this new flu virus, and so it spread very quickly and killed large numbers of people. While there have been many different pandemic diseases throughout history, all of them have a new thing in common.
First, all pandemics diseases spread from one person to another very easily. Second, while they may kill many people, they generally do not kill people very quickly. A good example of this would be the Marburg virus. The Marburg virus is an extremely infectious diseases. In addition, it is deadly. About 70%-80% of all people who get the Marburg virus died from the diseases. 
However, the Marburg virus has not become a pandemics because most people die within three days of getting the diseases. This means that the virus does not have enough time to spread a large number of people. The flu virus of 1918, on the other hand, generally took about a week to ten day to kill its victims, so it had more time to spread.
While we may never be able to completely stop pandemics, we can make them less common. Doctors carefully monitor new diseases that they fear could become pandemics. For example, in 2002, and 2003, doctors carefully watched SARS. Their health warming may have prevented SARS from becoming a pandemic.
