Read the passage and mark the letter A , B , C or D to answer the questions from 1 - 7
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 spread across the world , killing over 25 million people in only six months . Such terrible outbreaks of a diseases are called pandemics
Pandemics happen when a disease 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 pandemic 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 disease . In addition , it is deadly . About 70 - 80 % of all people who get the Marburg virus died from the disease . However , the Marburg virus has not become a pandemic because most people die within three days of getting the disease . 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 days 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 warnings may have prevented SARS from becoming a pandemic .
