So we're going to go over a couple different types of diseases in this lesson and build upon microbes So a disease outbreak happens when a disease happens.

When a disease occurs in greater numbers and expected in a community region or during a season.

Sometimes a single disease could be considered an outbreak if it is a new disease in a new place.

So this is a cool slide that shows you global infectious diseases, disease deaths by region.

So if we look across the X axis on the bottom, you look at sub Saharan Africa, South and Southeast Asia, Europe, the Middle East, America's East Asia and Pacific, and then globally at the very right, and then the different colors in the bar represent different types of diseases, um, neglected tropical diseases.

So there's lots of different types of diseases that can happen when you live in the tropics.

So that means somebody got a disease and then didn't get it taken care of of diarrhea is actually considered a disease, and a lot of people die from it.

If you look at it that, like light colored teal that is actually the biggest bar in the global section.

So globally more people die from diarrhea than anything else.

And that's because if diarrhea is left untreated, you can get dehydrated and very quickly die from it.

Vaccine preventable diseases that is the purple color.

That means people are dying from diseases that they could have gotten a vaccine from.

Malaria is the green, and if you look globally, the green global in the green.

Sub Saharan Africa is almost the same size, if not exactly, except for the Middle East has a little bar in Southeast Asia has a little bar.

Um, malaria is caused from mosquitoes, and that is something that can be prevented with proper equipment if you will.

And um, tuberculosis is the red, and then AIDS is the bluish color that is also in sub Saharan Africa.

So if you look at the higher rates of global infectious disease deaths, you condemn finitely notice a correlation between the um, lower deaths in the higher developed countries, the more developed countries and the higher deaths in the less developed countries.

So there's two different types of diseases there are, um, epidemics pandemics.

Both terms referred to the spread of infectious disease in a population.

They refer to the rate of infection and or the area that's infected.

But there have been an epidemic in a pandemic, and that's what we're going to go over in this lesson with an epidemic.

It's an illness or health related issue that showing up in more cases than would normally be expected.

It occurs when an infectious disease spreads rapidly to many people.

UM, it spreads too many people in a certain area, but not it doesn't spread all over the world.

So an example is in 2003 SARS, the respiratory.

Sudden acute respiratory syndrome took the lives of about 800 people worldwide.

Um, malaria can reach epidemic levels in Africa, but is not a threat worldwide, so it wouldn't become a pandemic.

And the prefix pan means all so if it's a pandemic that it's affecting people all over the world in very large numbers in SARS affected people worldwide, but not in very large numbers, 800 people seems like a lot.

But compared to the amount of people in the world, it's not.

This is a great map showing you the spread of disease and how diseases conspire, Ed.

And, um, the main way is by travel, obviously.

So you can see these lines are going thio different places from all over the They're traveling from one place to all of different places all over the world.

And if you have, you know, seven different people going from one place and their seven infected people traveling to seven very different countries and continents, then you are spreading disease really, really fast.

And you can see here by the different arrows att, the bottom in Europe, in Southeast Asia, how quickly the diseases travel pandemic is used to indicate a far higher number of people affected than an epidemic pan means all in refers to a larger region being affected.

Most serious case would be a global ah flu strain can start out as an epidemic but can also become a pandemic.

This is not unusual for a new virus because people's immune systems have not been exposed to it and are not ready to fight it off.

The swine flu started in Mexico City and is now in New Zealand Israel, Scotland and many days.

Another example of a pandemic is the 1918 Spanish flu and the black plague thes air examples of extreme extreme examples of pandemics.

Keep in mind that a pandemic does not necessarily mean millions of deaths.

It does mean, though, that a dude that it is geographically widespread epidemic so a lot of more than an epidemic.

 And this is actually a picture from the 1918 flu.
