Differentiate between any one pandemic in the past with covid-19 Pandemic.
Answers
An epidemic becomes a pandemic when it spreads over significant geographical areas and affects a large percent of the population.
In short, a pandemic is an epidemic on a national or global level.
Examples of past pandemics are the flu pandemic of 1968, the HIV/AIDS pandemic, and the bubonic plague.
How is a pandemic different:
Affects a wider geographical area, often worldwide
Infects a larger number of people
Often caused by a new virus or a new strain of virus that has not circulated within people for a long time
Humans have little to no immunity against the virus and it spreads quickly
Causes more deaths
Often creates social disruption and economic loss
The terms pandemic and epidemic are never used to indicate the severity of the disease, only the degree at which the disease is spreading.

Answer:
What is the difference between Influenza (Flu) and COVID-19?
Influenza (flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus first identified in 2019, and flu is caused by infection with influenza viruses.
COVID-19 seems to spread more easily than flu. However, as more people become fully vaccinated against COVID-19, the spread of the virus that causes COVID-19 should slow down. More information about COVID-19 vaccines and how well they work.
Compared to flu, COVID-19 can cause more serious illnesses in some people. COVID-19 can also take longer before people show symptoms and people can be contagious for longer. More information about differences between flu and COVID-19 is available in the different sections below.
Because some of the symptoms of flu, COVID-19, and other respiratory illnesses are similar, the difference between them cannot be made based on symptoms alone. Testing is needed to tell what the illness is and to confirm a diagnosis. People can be infected with both flu and the virus that causes COVID-19 at the same time and have symptoms of both influenza and COVID-19.
While more is learned every day about COVID-19 and the virus that causes it, there are still things, such as post-COVID conditions, that are unknown. This page compares COVID-19 and flu, given the best available information to date.
