Even though Science has made huge progress because of which there is a vaccine for almost all of them, but there are some underdeveloped countries in the rural areas who are completely clueless about these diseases. Many of these diseases can be prevented by educating, public awareness and health practices. Making the scenario watchful we have come up with the list of Top Pandemics that shook the world.
Here we bring to you some of the pandemics that have occurred over the years:

During that period WHO reported that around 250,000 to 500,000 died because of seasonal flu annually. Its first outbreak was in North America. Confirmed cases were around 700 million to 1.4 billion.
This is a contagious disease caused by bacteria which mainly infects the lungs and also later affects the organs as well. The symptoms of this disease involve fever, sweating, fatigue and weight loss. This may show up right away or in some cases it takes years.
In the year 2011, there was a death toll of 1.4 million people died due to this disease. Prevention is done on vaccinating infants who are mostly at the increased risk of being exposed and also of those who are with TB.
