What does mean by pandemic?

 A pandemic means disease which spread worldwide its called pandemic.

A pandemic is an epidemic of disease that has spread across a large region, or worldwide.

A pandemic is the global outbreak of a disease.

There are many examples in history, the most recent being the COVID-19 pandemic.

It can be stateas such by the World Health Organization on March 12, 2020.

Pandemic meaning

Apandemic is state as “an epidemic occurring Global , or over a very wide area,

Crossing international boundaries and usually affecting a large number of people”.

Preventing pandemic

It is important to try to prevent an epidemic from developing into pandemic.

This requires nation to act early and be get ready.

There are several ways to control virus it can also be affective.

  1. Quarantine – separate individuals who has infection from contact with others can send for incubation for some days.
  • Isolate – separate individuals who has infection contact with others.
  • Protect- protect themselves from other infected person through mask .

Stages of pandemic

The WHO (world health organization) defines 6 phases as follows.

Phase 1 – A virus is shown in animals but has not been shown to infections in humans.

Phase 2 – A known animal virus has caused an infection in humans

Phase 3 – Isolated incidence of cases or small clusters of the disease occurring in humans.

Phase-4- Possible cases of human-to-human transmission but not at a level to cause community-level outbreaks.

Phase 5 – Human to human transmission at a rate that causes an outbreak in communities.

Phase 6 – The spread of the disease between humans is now evident in more than one country.

Global pandemic meaning

pandemicis basically a global epidemic  an epidemic that spreads to more than one country.

The coronavirus, which emerged in China in December, has spread around the world,

Locking down entire nations, closing schools .It also includes the largest global recession .

forcing the postponement of events and concerts across the world.

Thepandemichas resulted in significant global social and economic disruption.

It has led to widespread supply shortages like panic buying, agricultural disruption, and food shortages.

Pandemic vs epidemic

PandemicEpidemic
pandemic is a kind of epidemic which has spread across a wider geographic range .An epidemic is an outbreak of disease that spreads quickly and affects many individuals at the same time. 
A pandemic affects large number of people.An epidemic, which has affected a significant portion of the population.
 Pandemic is an epidemic that’s spread over multiple countries or continents. Epidemic is a disease that affects a large number of people within a community, population, or region.

Pandemic history

There have been a number of pandemics since the beginning of the 20th century.

1918/19=Spanish flu

1957,1968=Flu pandemics

2009= H1N1

2019/20=COVID

Among the best-known pandemics is the Black Death, a plague which spread across Asia and Europe in the middle of the 14th century.

The deadliestpandemic in history was the Spanish flu of 1918. The virus infected an estimated one-third of the world’s population.

Andit was responsible for causing between 20 million and 50 million deaths that’s an estimated 1% to 3% mortality rate.

The virus didn’t develop in Spain, but the country was the first to report on the outbreak, so people began calling it the Spanish flu (the Spanish thought it started in France and called it the “French flu”).

What is endemic?

When a disease exists all the time in a specific region or among a particular population, it’s known as endemic.

Endemic is something that belongs to a particular people or country.

What’s the difference between epidemic and endemic?

An epidemic is actively spreading new cases of the disease .

More broadly, it’s used to describe any problem that’s out of control, such as “the opioid epidemic.”

 An epidemic is often localized to a region, but the number of those infected in that region is remarkably higher than normal.

For example, when COVID-19 was lean to Wuhan, China, it was an epidemic. The geographical spread turned it into a pandemic.

How long do pandemics last

The best therapies and vaccines in the world, this virus is almost certainly going to be with us forever, even after the pandemic phase has passed.

To eliminate a virus from the human population is incredibly difficult.

We’ve only ever done it with one human pathogen, and that’s smallpox. To do that, you need a global vaccination strategy.

On top of that, you need a vaccine that provides essentially 100 percent protection against the virus.

The pandemic “likely won’t be stop until 60% to 70% of the population is immune”, the report said.

The worst of the three scenarios they outline involves a third, larger wave of coronavirus infections this fall.

Covid-19 would have a seasonal pattern, spreading in the winter months when kids are in school and when we spend more time indoors in proximity to each other. 

The coronavirus pandemic may last until 2022, according to a report published.

COVID-19 cases worldwide, as of June 24, 2021. 

June 24, 2021, the coronavirus disease (COVID-19) outbreak occurred in more than 210 countries. The virus has infected more than 180 million people around the world and in some deaths of approximately 3.9 million. The most severely affected countries, particularly the United States, Mexico, Brazil, and India. 

However, in India COVID active cases are 643,194 recoverd cases are 28,994,855 deaths are 390,660 total vaccination done are29,46,39,511.these data are till date of 24 june 2021.

The first case was detected in China’s Hubei province, in late December 2019. The virus is highly transmissible, and thousands of new cases are being reported around the world every day. 

Coughing and sneezing are the most common modes of transmission, which is similar to that of the SARS coronavirus outbreak, which is spread through cough and sneeze droplets that are released into the air by infected people. 

Coronaviruses are a family of viruses that can be transmitted between animals and humans, causing diseases that can range from the common cold to more serious respiratory diseases. 

In February 2020, the International Committee on Taxonomy of Viruses, and the World Health Organization announced the official names of both the virus and the disease: SARS-CoV-2, COVID-19, respectively. 

The name of the disease comes from the word on the coronavirus and the disease, while the number 19 in the year it was published. 

The death rate of COVID -19 worldwide as of 24 june 2021.

June 24, 2021, the outbreak of the coronavirus disease (COVID-19) has spread to six continents and more than 3.9 million people have died after contracting the respiratory virus. More than 127,000 of those deaths have occurred in Italy. 

Approximately 215 countries and territories all over the world have been affected by COVID-19. The virus is still circulating in a very dynamic way, and a lot of countries have introduced a lockdown of the rules and regulations to slow down the spread will be registered during the winter months. 

In addition, the new travel restrictions were introduced due to the discovery of new possibilities, in particular, the first has been identified in the united kingdom and South Africa, and so on. 

In other country like USA death are 618294 ,Brazil 507240, India 392014,mexico 231847 ,Russia 130895 ,UK 128027.

What are the symptoms of the virus? 

It may take up to 14 days before symptoms of the disease are beginning to be seen. The most common symptoms are fever and a dry cough, which leads to shortness of breath.

The early symptoms are similar to those of other common viruses such as the common cold or flu. These diseases are more common in the cold months, but there has been no conclusive evidence of the fact that the temperature affects the spread of the SARS-CoV-2 virus. If you have any of these symptoms, you should seek medical advice. 

The SARS-CoV-2 variants 

Since the start of the pandemic who recommend working against virus variants.

 Institutions and scientists are monitoring the evolution of the SARS-CoV-2 since February 2, 2020. 

A variant of the SARS-CoV-2, which meets the VOI definition. 

Increased transmission, or adverse changes in the epidemiology of COVID-19.

 However, this pandemic Reduced the effectiveness of health and social action.

 The incubation period for SARS-CoV-2 is estimated to be around 5.1 days, with 97.5% of the people who develop clinical signs doing so within 11.5 days. 

 Research studies have examined how the SARS-CoV-2 interacting with the host, indicating that the smell-sensitive cells in the nose are an important gateway to the reduced cell infectivity. 

and viral replication moving away from the nasal cavity towards the lungs. 

 The protein called neuropilin-1 on the surface of human cells to facilitate viral infection. 

Where did covid-19 has become a pandemic? 

 The World Health Organization declared the outbreak a public health emergency of international concern on January 30, 2020, and a global pandemic on March 11, 2020. 

 As the COVID-19 pandemic, also known as the coronavirus pandemic, the ongoing global coronavirus disease to be a pandemic of 2019 (COVID-19), caused by severe acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2).

The virus, which was first identified in December 2019 in Wuhan, China. The World Health Organization declared a public health emergency of international concern on January 30, 2020, and then it has been declared a global pandemic on March 11, 2020.

On June 25, 2021, is more than 179 million cases have been confirmed, with more than 3.9 million, which confirmed the deaths attributed to COVID-19, and that’s what makes it one of the most deadly pandemics in the picture. 

 The pandemic has resulted in significant global social and economic disruption, including the largest global recession since the Great Depression of the 1930s. 

 This has led to widespread supply shortages created by panic shopping, as trigger failures and food shortages. However, there was also a reduction in the emissions of pollutants and greenhouse gases .

Conclusion:

Thus, from above we can conclude that this pandemic may last until 2022.till then we must vaccinate our selves and our family members .however we may say that precaution is must for this pandemic .we must take vaccine .it can also shown that people who are taking precaution like wearing mask, do sanitize ,or get vaccinated they are quite safe than other who are not following these. now by june 2021 it seems that cases are decreases in world wide .
