What does the term Pandemic mean?
an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population is known as pandemic.
Compared to an epidemic disease, a pandemic disease is an epidemic that has spread over a large area, that is, it’s “prevalent throughout an entire country, continent, or the whole world.”
Pandemic is also used as a noun, meaning “a pandemic disease.” The WHO more specifically defines a pandemic as “a worldwide spread of a new disease.” On March 11, the WHO officially declared the COVID-19 outbreak a pandemic due to the global spread and severity of the disease.
While pandemic can be used for a disease that has spread across an entire country or other large landmass, the word is generally reserved for diseases that have spread across continents or the entire world. For instance: After documenting cases in all continents except Antarctica, scientists declared the disease a pandemic.
As an adjective, pandemic can also mean “general” and “universal,” also often with a negative connotation. However, pandemic appears to be most commonly used in the context of epidemiology, which is concerned with infectious diseases.
Pandemic also entered English, through Latin, in the 1600s. Like epidemic, pandemic ultimately derives from the Greek pándēmos, “common, public.” Also like epidemic, pandemic was originally used of diseases when in came into English.
Discuss the impact of lockdown due to corona pandemic on the environment.
There’s clear water in the Venice canals, blue skies over Delhi and wild animals are roaming boldly in locked-down cities. The oil industry and airlines are floundering in this new world, and carbon emissions are falling fast.
But there are also mountains of food going to waste that our supply chains aren’t set up to deal with. And, what’s more, the radical changes to daily life that we’re seeing now are not – thankfully – going to be permanent.
History tells us that when emissions have fallen sharply in the past, as they do after recessions, there’s often a rocketing rebound that wipes out any short-term cut in emissions.
In a matter of months, the world has been transformed. Thousands of people have already died, and hundreds of thousands more have fallen ill, from a coronavirus that was previously unknown before appearing in the city of Wuhan in December 2019. For millions of others who have not caught the disease, their entire way of life has changed by it.
The streets of Wuhan, China, are deserted after authorities implemented a strict lockdown. In Italy, the most extensive travel restrictions are in place since World War Two. In London, the normally bustling pubs, bars and theatres have been closed and people have been told to stay in their homes. Worldwide, flights are being cancelled or turning around in mid-air, as the aviation industry buckles. Those who are able to do so are holed up at home, practicing social distancing and working remotely.
It is all aimed at controlling the spread of Covid-19, and hopefully reducing the death toll. But all this change has also led to some unexpected consequences. As industries, transport networks and businesses have closed down, it has brought a sudden drop in carbon emissions. Compared with this time last year, levels of pollution in New York have reduced by nearly 50% because of measures to contain the virus.
