What is a Pandemic?

A pandemic is the spread of an infectious disease, globally, as defined by The World Health Organization. It occurs when an infection is widely spread by bacteria or viruses. The disease behind the pandemic can cause serious illness and can easily spread from one person to another. The epidemic is limited to a city, region, or country, but the epidemic is spreading beyond national borders and around the world. Authorities consider it an epidemic when the number of infected people in a certain area exceeds the estimated number, and if the infection spreads to several countries at once, it can develop into a pandemic.

As of March 2020, the world is grappling with the global outbreak of COVID-19. On March 11, the World Health Organization (WHO), a reliable source, reported that the disease was showing signs of a pandemic. Many governments had restricted freedom of movement and isolated residents to prevent the spread of the pandemic.

A new strain or subtype of the virus that can be easily transmitted between people could cause a pandemic. Bacteria that have become resistant to antibiotic treatment can also cause rapid spread. Epidemics sometimes occur when a new disease develops the ability to spread rapidly, such as the plague or bubonic plague. People may have little or no immunity to the new virus. Often, new viruses cannot spread between animals and humans. However, if the disease changes or mutates, it can easily spread and cause a pandemic.

Epidemics of seasonal influenza (flu) usually result from virus subtypes already circulating in the human body. On the other hand, new subtypes usually cause pandemics. This subtype has not previously cycled in humans. Pandemics affect more people and can be more deadly than epidemics. It can also lead to great social upheaval, economic loss and general misfortune.

The COVID-19 Pandemic : Then

Since March 2020, the current pandemic has had an unprecedented impact around the world. COVID-19 is a disease caused by a type of coronavirus infection. The virus started causing infections in Wuhan, China before it spread around the world. According to WHO recommendations, more than a third of the world's population was under quarantine. Several countries including the US, UK, India and China had closed their borders, affecting travel and industry around the world.

In many countries, people lost their jobs as "non-essential" businesses had to be closed to contain the spread of the virus. Restaurants, fitness studios, places of worship, parks and offices were closed in many places. The pandemic also put pressure on the healthcare system, increasing demand for certain treatments. People with severe symptoms of COVID-19 were using more ventilators and beds in intensive care units. As a result, resources were not  sufficient for others who needed this equipment.

However, countries had to take steps to resolve this problem. For example, the US government asked companies such as Ford and General Motors to begin manufacturing ventilators, ventilators and face coverings to meet growing demand. The authorities hoped that these emergency production measures and movement restrictions, which have global economic and social consequences, would slow the spread of the disease. Countries jointly purchased medical equipment and developed vaccines.

Covid in 2022 : Now

As the coronavirus pandemic enters its third year, many local governments are easing public health restrictions. While most of the Indian population is now thought to be immune to SARS-CoV-2, either through vaccination or natural infection, experience and data show that new mutations are emerging causing localized outbreaks and unexpected consequences for control strategies. prevention and treatment.

A common question in almost everyone’s mind is when will life return to normal. This question is very difficult to understand and various predictions have been made. In this study, global and COVID-19 mortality were analyzed using non-linear regression analysis. Analysis suggests that the COVID-19 pandemic may end in 2022, but by 2023, COVID-19 could be one to two times more deadly than seasonal influenza. The forecast takes into account the possibility of the emergence of new strains of SARS-CoV. 2 and is confirmed by the properties of the Omicron variant and other facts. Because herd immunity to COVID-19 from natural exposure and mass vaccination varies from country to country, COVID-19 may be slightly more deadly than expected in some countries over the next few years. The future of COVID-19 will provide many opportunities, but these statistical projections can help you make informed decisions and provide examples of projections.
