COVID-19 Known and Unknown After 5 Years

Five Years of COVID-19: How the Pandemic Altered the World and What is Coming Next

In China’s Wuhan region, the world had little inkling that a disease was set to surface and transform the world entirely in just five years. What began as a simple outbreak escalated into a phenomenal pandemic within no time. The world’s perspective towards life, work, and socialization was fundamentally altered. Although COVID does not monopolize news like it used to, its consequences are far-reaching. The virus still propagates and poses a threat to global health and security.

The Origin Debate: Where Did COVID-19 Start From?

Even after all the studies conducted over the years, the origin of SARS-CoV-2 is still not explicitly defined. Most experts believe this virus stemmed from bats, leaving them the most popular outbreak source. From there, the virus would have had to cross over to an intermediary animal, which could easily include raccoon dogs, civet cats, or bamboo rats, before finally infecting humans at a Wuhan market. This phenomenon is not novel; it is how most previous viruses spread around, including SARS in 2002-2003.

The presence of labs that examine coronaviruses in Wuhan has only intensified the debate surrounding the possibility of a lab leak. Global political strains, the lack of essential information, and a worry over the lack of openness of information have only sabotaged the quest for answers. Consequently, a decade’s worth of conversation and ambiguity may stem from the fact that the real cause of the pandemic may always remain unsolved.

The Losses: Understanding the Human Cost

Over 7 million people have died from COVID-19, as reported by the World Health Organization (WHO). On the contrary, researchers suggest that the actual figure could be a lot more than 20 million when taking into consideration those whose cases were never admitted and those who died due to inadequate medical services.

Throughout America, on average, 900 people die a week due to COVID-19. Adults aged 75 years and above are the most vulnerable to the disease, with close to half of all hospitalizations and deaths in that age group. Vaccines and natural defenses certainly helped moderate the virus’s severity, although it is still a danger to those considered most at risk.

The Vaccine Revolution: Changing the Dynamics of Global Health

Perhaps the most notable aspect of the pandemic is conquering its heights through the swift development and distribution of vaccines. Using mRNA technology, scientists integrated effective vaccines within a year. Programs that were developed decades later came into action. Companies such as Pfizer and Modern pioneered the effort, then came Novavax and others.

By the end of 2021, more than 13 billion vaccine doses had been administered globally. Developing nations were more limited in resources initially, but there was a global campaign to provide vaccines to lower-middle countries. Some regions did make notable advancements, only to be slowed down by logistical bottlenecks and vaccine reluctance.

Even though vaccines have proven most effective in minimizing severe disease and mortality, their effectiveness towards infection has gone down over some time. This has resulted in the formulation of new booster shots aimed at new variants. These boosters had significantly aided. However, frustration is felt among those expecting immunity for life from just a single booster. Next-generation vaccines are being developed, including nasal sprays, which are more effective in curbing transmission and increasing the effective duration.

The Variant Puzzle Omicron: The COVID-19 Changes Much like its siblings, SARS-CoV-2 also has its own unique infection spread. Since the first outbreak, many variants of COVID-19 have emerged, each with its own problems. To make life easier, scientists have used Greek letters for identification. Examples include Beta, Gamma, and Delta.

Astute followers will recall the alarming Delta variant that emerged around mid-2021. While Delta had the worst case of severity, hospitalization and infection rates were alarmingly high. It is reasoned that the Omicron variant, appearing late in 2021, rapidly grew to dominate the infection. Omicron did single-handedly cause a global infection spike, but because of the advances in medicine, new infections were thanks to the vaccines and people having developed healthy immunity after getting Delta.

Currently, Omicron’s subvariants are the most frequently encountered. One of the most recent strains in the United States referred to as XEC has nearly claimed half of the infections within the nation. However, a lack of measures such as Booster vaccines has made people vulnerable to XEC infections. Experts claim that these overwhelming infections are easy to control by aiding individuals with enablements that allow combat against said hostility.

Long COVID-19: The Lingering Shadow of the Pandemic

For many, COVID-19 was a temporary illness they could recover from. But for millions of others, it turned into a nightmare that didn’t end. Instead of bouncing back, they found themselves dealing with a long-lasting and often debilitating condition called COVID-19.

Chronic fatigue, brain fog, cardiovascular issues, and more are symptoms that need to be dealt with. The myriad of symptoms make it one of the most puzzling medical challenges.

Though long-term COVID-19 can develop after even mild infections, the probability is higher for those suffering from severe cases. Researchers are working around the clock to try to comprehend the mystery, but some assert that remnants of the virus may persist in the body, triggering prolonged immune responses.

Although vaccination has shown promising results in reducing the chance of suffering from long-term COVID-19, there is no particular cure to solve the problem. Scientists are working tirelessly to find a solution or cure to help make things easier for patients and their long-suffering.

A New Normal: Living with COVID-19 Today, five years after the pandemic began, we have adapted to the COVID-inflicted world. There aren’t substantial mask mandates and lockdowns as frequently, but the lessons learned from the pandemic are still fresh and used to shape other public health strategies.

Problems in the world’s health systems during the pandemic were magnified, almost like an untreated wound. Experts profess that increased surveillance of outbreaks, international vaccine allocation, and inter-country cooperation should be bolstered to counteract future pandemics.

Though COVID-19 is no longer a threat like in the past, it still poses an exigent danger that needs continual readiness and swift strategic adaptation. Retrospectively, we cannot lose sight of how the war against COVID-19 wasn’t just one for mankind to fight; now, we all should come together for this cause and build stronger inter-nation connections.

What next?

The war and conflict that stemmed from the pandemic were a result of unpreparedness. The imbalance created was unprecedented, and now it is vital to eliminate the backlog of problems caused by this unhealthful phenomenon. Despite the immediate threat of disappearing, COVID-19 still exists in a different form, as new mutations are always possible.

Time will unfold what is to come, but one thing for sure is that healthcare system improvement and access become far too simple to target without collaboration between countries and regions. The UK’s method of changing health policies diversely for each state in case of a pandemic instantly serves as wisdom for the future.

The bottom line is that Covid-19 has significantly impacted the world.
