List of Pandemic Diseases Polio was a pandemic disease in the 1950s. Due to a subsequent world effort, it was considered eradicated until the 1980s when countries ceased immunizing children against the disease. WHO's efforts to bring polio under control have reduced the number of cases from 350,000 in 1988 to less than 1,200 in 2005.

Endemic Disease in Certain Populations Endemic diseases are often confused with epidemics. However, an epidemic refers to an outbreak of a disease that is spreading through one or more populations. In contrast, an endemic disease is one that is constantly present in a group or geographic area. Pandemics are world wide epidemics. Under certain circumstances, an epidemic can lead to a disease becoming endemic.

The Difference Between an Epidemic and a Pandemic A pandemic differs greatly from an epidemic. Like an epidemic, a pandemic refers to a contagious, infectious or viral illness that spreads. However, unlike an epidemic, a pandemic is not limited to one specific geographic region. Instead, a pandemic has the potential to include millions of people in many areas and countries across the globe, according to the World Health Organization's description.

- What is pandemic influenza? An influenza pandemic occurs when a new strain of influenza emerges to which most of the human population has not been previously exposed. This means that immunity within the community is low, allowing rapid infection and transmission of the new strain amongst people on a global scale.nfection with influenza virus, or immunisation, induces the body to produce antibodies to the strain(s) of virus encountered. Antibodies against the haemagglutinin are the most important for protecting us against influenza virus infection.

List of Pandemic Diseases The threat of new pandemics increases in an age where people travel by air. Photo Credit muratart/iStock/Getty Images. The World Health Organization (WHO) defines key terms used in the discussion of pandemic diseases: A disease epidemic occurs when there are more cases of that disease than normal. A pandemic is a worldwide epidemic of a disease..

Music Theory/Chords When a chord is referred to as simply a seventh chord, usually the dominant seventh is meant, which is a major triad with a minor seventh, for instance, C-E-G-B♭. It is called the dominant seventh because the V chord, or dominant chord in the Latin naming system, is the only major chord in the major scale that can naturally contain a minor seventh. Because all sevenths are dissonant intervals, any seventh chord is dissonant, in other words, a seventh chord is more tense than a major or minor chord.
