In the modern times, even though we have developed enough, but there is still a surge, a high level of infectious disease spread.
00:14
So the infectious diseases spreading even though we are living in this modern world.
00:28
There are many factors, many reasons why this is happening in the 21st century.
00:37
Even when we succeeded, we were successful in 20th century experiments.
00:43
There were many experiments, many discoveries that led to many successful attempts in the 20th century.
00:49
But still in 21st century, we are facing infectious diseases.
00:53
These infectious diseases are spreading widely.
00:56
Many reasons one of them is antibiotic resistance in antibiotic resistance what happens is when we overuse overuse antibiotics are basically to resist the bacterial truth when we overuse the bacteria on which this antibiotic was used.
01:22
This bacteria mutates and after mutation it finally evolves and when this evolves this will reproduce and if this reproduce then it is going to multiply and increase and then what happens? resistance happens.
01:48
Happens these bacteria are going to show resistance against the antibiotic so over usage of this antibiotic is going to mutate the some bacteria and these mutated bacteria will finally reproduce and reproduce and a stage will come where almost generally all the bacteria will become resistance towards the antibiotic use another reason for this spreading of infectious disease in 21st in this modern times it can be because of globalization now globalization what is it now traveling has increased traveling and has increased we can blow globally anywhere we want we are interconnected we are are interconnected with each other we can go from one place to another one country to another country now this what this does is it can easily spread diseases so spreading of diseases very easy spreading of disease becomes easy now the traveling portion let's say one person came to travel in some country a and he took a disease with him and he went back to his country so what is going to happen he is going to spread it globally so global spread will happen and this is the very good example to this globalization is covid 19.

In covid 19 the pandemic was due to this only we were so globally interconnected with each other that this virus it spread with a very very high speed third reason is urbanization urbanization almost all the paths not all but almost all the paths are becoming urban now due to urbanization the population is increasing because the population is increasing, there is poor sanitation seen...
