What is the meaning of pandemic? Write in 100 words. Who will give the answer I will mark it as brainliest answer

Answer:
The word "pandemic comes from the Greek 'pandemos,' which means everybody. Demos means the population. Pan meaning everyone. So 'pandemos' is a concept where there's a belief that the whole world's population will likely be exposed to this infection and potentially a proportion of them fall sick.
Pandemic is the highest level in global health emergencies that warns of a disease spreading at a mass level. At first, WHO has been avoiding calling it a pandemic as it might panic people across the world and classified it as a series of epidemics.

Explanation:
According to the WHOTrusted Source, a pandemic is defined as the “worldwide spread of a new disease.”
When a new disease first emerges, most of us lack the natural immunity to fight it off. This can cause a sudden, sometimes rapid, spread of the disease between people, across communities, and around the world. Without a natural immunity to fight off an illness, many people can become sick as it spreads.
The WHO is responsible for announcing the emergence of a new pandemic based on how the spread of the disease fits into the following 6 phasesTrusted Source:
Phase 1. Viruses circulating among animal populations haven’t been shown to transmit to human beings. They’re not considered a threat and there’s little risk of a pandemic.
Phase 2. A new animal virus circulating among animal populations has been shown to transmit to human beings. This new virus is considered a threat and signals the potential risk of a pandemic.
Phase 3. The animal virus has caused disease in a small cluster of human beings through animal to human transmission. However, human to human transmission is too low to cause community outbreaks. This means that the virus places humans at risk but is unlikely to cause a pandemic.
Phase 4. There has been human-to-human transmission of the new virus in considerable enough numbers to lead to community outbreaks. This kind of transmission among humans signals a high risk of a pandemic developing.
Phase 5. There has been transmission of the new virus in at least two countries within the WHO regionTrusted Source. Even though only two countries have been affected by the new virus at this point, a global pandemic is inevitable.
Phase 6. There has been transmission of the new virus in at least one additional country within the WHO region. This is known as the pandemic phase and signals that a global pandemic is currently occurring.
As you can see above, pandemics aren’t necessarily defined by their growth rate but rather by the spread of the disease. However, understanding the growth rate of a pandemic can still help health officials prepare for an outbreak.
Many disease outbreaksTrusted Source follow a growth or spread pattern described as exponential growth. This means they spread at a rapid rate over a specific period of time — days, weeks, or months.
Think of driving a car and pressing on the gas pedal. The farther you travel, the faster you go — that’s exponential growth. Many initial disease outbreaks, like the 1918 influenza pandemic, seem to follow this growth pattern.
Some diseases also spread sub-exponentially, which is at a slower rate. This is like a car that maintains speed going forward — it doesn’t increase in speed across the distance it travels.
For example, one research studyTrusted Source found that the 2014 Ebola epidemic seemed to follow a much slower disease progression at the local level in some countries even though it spread faster, or exponentially, in others.
When public health officials know how quickly a disease is spreading, it can help them determine how quickly we need to move to help slow that spread.
