Hi friends, hope you're fine. Today let us understand three confusing terms
0:04
epidemic, pandemic and endemic within three to five minutes. WHO classified diseases as epidemic, pandemic or endemic based on diseases rate of spread
0:18
Remember it's not based on the severity of a disease. Let's begin with epidemic
0:24
The word origin epidemic epi means upon whereas demic or demos means people or
0:32
population. Let's take an example Ebola outbreak in West Africa. So epidemic just
0:40
like this a disease with sudden increase in rate of number of a disease in a
0:46
specific geographical area or a population is called as an epidemic disease or a disease outbreak in a specific geographical area or a population. Other examples
0:58
include 1949 smallpox epidemic in USA, yellow fever epidemic etc. Second term pandemic. Pan means
1:07
all whereas demic means people or population. Now we are familiar with the term COVID-19 pandemic
1:15
A disease with a sudden increase in number of disease cases spreading several countries or all over the world is termed as pandemic
1:26
Or in other words, first a disease outbreak starts as an epidemic
1:32
If it spreads several countries or continents or all over the world then the disease is called as pandemic Other examples include 2009 swine flu pandemic 1918 Spanish flu
1:48
pandemic, HIV AIDS pandemic etc. And the final one is endemic. N means in
1:57
whereas demic means people or population. Let's take an example to understand this
2:03
term endemic. Panda is endemic to China that means the geographical distribution
2:09
of panda is limited or restricted within China. Just like that an endemic
2:18
disease is a disease that is constantly present in a population or a region with
2:24
a relatively low spread rate and the disease rates are predictable. Examples
2:30
include malaria in Africa, Asia, Latin America and Middle East, Chagas disease in Mexico, South and
2:37
Central America and the diseases are often seasonal or periodical, constantly reappearing in a
2:44
population. Let me summarize. An epidemic is a disease outbreak in a specific geographical area
2:51
or a population whereas pandemic is a disease outbreak spreading across several continents or
2:57
countries or all over the world. Whereas an endemic disease is a disease that is
3:03
constantly present in a population with a relatively low spread rate and is
3:09
often seasonal or periodical. Hope you understand these terms. Thank you so much
