So in decision, we will talk about waters an outbreak.

We will talk about the various types of outbreak.

I'm understanding the friend of Mexico, Garrity and Eggs.

So let's first understand outbreak.

When you have more than expected number of cases that recorded in area we call, it does outbreaks.

It's more than the expected number.

Whatever we consider it on this outbreak and before they're classified and do three heads.

Now, this is very, very important.

It is endemic Britta Mink or Brenda Ming.

So we would be understanding the storms.

One Bible.

Very important in line off the reason Corona virus news that is coming up now.

These three types that be classified as in the Make Brenda make on a pretty make our definitely can be contagious or known contagious.

So if we talk about endemic and the bank means it is a specific toe, a region or an area.

So there is a very high proportion of that disease found in a specific return.

For example, yellow fever.

So it's endemic to the bonds off Africa.

So what is hyper endemic hyper in the MiG means at this persistent on has very, very high level off occurrences that could be seen so further sub classifications on the endemic could be our is hyper endemic understanding the very basics off the storm endemic.

So let's say ding you is endemic.

Disease on it is endemic to the region where you have higher proportion off mosquitoes at a scene.

But in a recent case, it was witness that there was an outbreak off this disease and big island off of I.

How about how I do not have the population for the thank you.

Thank you.

Mosquitoes.

Now what actually happened was you had one of the persons who traveled to the region of heaven by on at that point there wa ce the local chain of transmission that gained moment them so this endemic disease slowly and gradually waas no more on and the make because it was you doing outbreak off the important disease that was seen from another nation.

So what happens in this case is slowly and gradually tones in tow.

Epidemic epidemic means many people are attacked or are affected.

We could see at the same time on get this bridge true on in and around different communities.

So what happens during an endemic s you have usually two weeks or less duration in which that disease spreads on this create numerous concerns across the globe.

So so far past 20 then we have a witness.

Nearly 14 epidemic diseases that have come up.

One of the most important once was Ebola.

So Ebola in Africa was one of the major ones that we talk about the next roars You had the outbreak off SARS savior acute respiratory syndrome that was seen in 2000 and three on.

If we want to classify this epidemic, we can say this epidemic could be both.

It could be known and pictures as Vela's infections.

So infectious good example, were beating you.

As we said Northern Pictures, you would have diabetes obesity, which is very intimate to specific reasons where you have higher standards of living culture.

Sedentary lifestyle.

We could say our higher stress levels now coming on, Do the infectious forms off epidemic.

This infectious form of a Britta Mick.

You can understand that what are the factors that affected first is you have increasing the amount of violence or the agent which is causing this virus.

The next er's you are trying to introduce a setting where the things are much more off easily transmitted from a susceptible person toe.

Another person I'm there is also changing the susceptibility that has seen.

So that is where we focus our epidemics.

Now this epidemic can again be classified.

And don't various criterias point so separate, um, it means that it would have been one incubation Beat it.

You would have a group that would be exposed to, let's say, ah, group off.

The students went to a restaurant for dinner on there was a food poisoning.

So what would happen?

That would be a pouring swords in the epidemic story on.

That would mean that all those persons who are affected by that food would be affective.

So this is a point towards you have very brief period off exposure that the scene, uh, you have one Incubation, Peter.

Dr C.

The next is common source.

Common source means the same case when you have bean seeing that there is exposure for ah longer duration.

So it could be days.

It could be weeks, or it could be even months that could be seen.

We say it is a common source outbreak on.

There is a range of incubation period that as witness in this propagated outbreak, means it is transmitted from one person to another person.

So you would have one person on that one person could be able to transfer to do another person on.

That is where we say it is a propagated out outbreak.

That scene usually Derek person to person call.

That is where we have the propagated outbreaks.

The next is mixed.

Outbreak makes out breakers one where you have both the propagated outbreak as well as the common tours outbreak.

Uh, this is for Lord, even by secondary explosion from person to person.

It's not like a North Eric person to person contact, but as well a second record act that could be seen on this is where we say it is a mixed outbreak.

So this are the classification for epidemic.

The next s pandemic.

No borders, pandemic men and disease spread throughout the globe.

We say it is up in the make disease.

In the history we have seen small box, we have seen tuberculosis, black death as some of the examples which hard kill nearly 75 million population in back and 13 fifties.

So those were other diseases which were considered as endemic in 2000 and nine.

We witness each one and then swine flu on that was also categorized as pandemic because of killing nearly 14,000 plus people across the group.

1918 was a very weird example.

Where you hard Spanish flu, that desperate.

Now this.

We would be covering in a separate lecture where we are discussing about Corona virus on influence a pandemic.

So we were talking about the Spanish flu in the day there.

However, Justin on Spanish flu is nothing to do with its origin in the Spain.

It most raised very much before it foreseen and the speed.

But it was just because off the world war going on, Spain being a neutral country and it did not had its restrictions or censorship.

It was finally declared that this was being a spread in Spain and therefore it was JI name as a Spanish flu on this waas one off the sea, various fluids because it was believed that during World War one you had nearly 17 million people like were killed.

However, this is Spanish flu killed 15 million people, which Woz nearly 1/5 off, 1/3 off.

Those who were infected on the infected population was nearly 1 50 million.

The next is 1957.

When you heard the Asian flu that aspirin on in 1968 you had the Hong Kong flu that spread on these flu are also call a scientifically gold has influence.

Also, pandemic occurs in Viv's.

It's not a kind of continuous transmissions odyssey, but let's say it was one country that was exposed to her.

I'm.

A few days later it moved to another country, and there was a certain boast off that disease in another country.

So water becomes is a V shaped Martin.

It's not always that all the parts of the globe would be affected, but yes, a lot off the global be affected.

So influenza as a pandemic if we talk about has been categorized under six phases.

The first fees is off phase, where the virus has no known infections in human beings.

So you do not have, uh, any idea that this species would be infecting human beings?

The second stage is a stage where flu virus has infected the human being.

Now most off the influence of iris are zoonotic.

Zoonotic means they have a tendency to spread from animals to human beings.

So in the second phase, we say it is infected.

The human beings that infected the turkeys is a sporting Dickie's.

Oh, what a cluster case that means in a specific area you would see Lord off cases where you would have influences that would be seen are sporadic means irregular random cases across the globe.

Very would see this influence are growing up.

The four keys is the risk for pandemic is higher but nor peered certain, so it's believed that it could spread, warned bite.

But it has nor being yet assured, that it would have spread worldwide.

The next phase talks about the spread of their disease from one country to another.

Now, at this point, we have proved that the disease is spreading from one point to another on the blue.

Actual classifies this as the most important piece.

Finally, you have Feast Six very would have the community level outbreak that a scene in atleast one country bridges in addition to the country that was recognize right, a blue adorned for his fight.

So every time you would have a new country that would, in turn into you would say it's part off a global pandemic.

He's six.

Now what other important indicators that we consider first off all the number of people that are affected by the virus.

The signal is the severity of their disease that has taken in broken the terrorists of a little urban population who are all are expected to be affected by it.

On the last runners border the effectiveness.

Oh, are the preventive steps that are taken?

Don't mitigated.

The next is how can we actually prevent the influence up endemic.

So some of the most common types say, is washing your hands regularly avoiding overcrowded place covering washing your hands.

Covering your face while coughing or sneezing are depending on the severity, we say the use or face mask is also recommended in certain cases.

On, if possible, try to minimize the outdoor activities.

Minimize the contact home.

Learning these activities in case of students is encourage.

Extra food supplies could be kept at home in orderto take out a pandemic that is is spreading now.

Water the severity.

CDC classifies the pandemic severity index under five categories from Category one to a Category five on Borders.

The similarity.

This is based on the number off expected debts that our cause because off the spirit of the enemy.

So when you're talking about influenza or corona virus as of now as a pandemic for gov consider is anti virals now what is the difference between India by They can in divine indeed, buy tickets given in a bacterial infection, and the viral is given an hour viral infection and dividers.

I'm difficult in idea or in terms, we could say, because virus mutates at a very frustrating.

So when you have a very first rate of mutation, either you would have to create influence a virus influence of vaccination that could understand or deal with all the strains that have mutated on that is yet in progress.

So, so far, the common and dividers that are considered are the following.

Compositions that are given on definitely thes are important in case the pandemic CVRD spreads.

It's also important for preparedness and planning by the local authorities.

The next type that beyond this town, this cluster on the sporting pleasure as visa is accumulation into small groups at the particular given time and space.

So it is accumulation into certain smaller groups groups.

But that accumulation ISS higher or more than the expected number that could be found in that reason on, That's where the seeds up cluster approach the next census Sporting sporting means.

It's even infrequent on that scene, irregularly in different parts of the world.

On that's where we call it as a supporter.

So do they be understood Waters outbreak, And that makes everything make spending me the categorization under epidemics, the types of Epidemics on Dependent Exit Garrity.

Next, this topic is very, very important in line with the recent guru know it s a spray the foot recovering another class where we would be talking about few night fluids.

Some of the major terms and organizations associated with the epidemic.
