A Pandemic

The COVID-19 is humanity’s newest foe, having the potential to prematurely affect and end millions of lives. Labs and Virologists around the world are working around the clock to know about their enemy. As many as 213 countries and territories have registered COVID-19 cases, and the entire world is buzzing with uncertainty. Many countries have declared restrictive measures, such as lockdown, shelter in place, or stay at home orders, to contain the pandemic at a local level.Some European countries have reacted sooner to the steep rise in COVID-19 cases than others. On March 10, Italy ordered a strict nationwide lockdown, becoming the first country in Europe to do so.The government banned all travel in the country, and people could only leave their homes for essential reasons — such as to buy food. When going out, people had to carry declaration forms and wear face masks and disposable gloves.

Three important questions are defending this virus. How does it reproduce so quickly once it is inside us? What makes this virus so good at infecting the people? Why doesn’t the virus cause symptoms straightaway, allowing it to spread undetected? Answers to these questions will penetrate this defense and shatter this virus into pieces.

Corona Viruses are a large family of viruses that can cause illnesses ranging widely in severity. The first known severe illness caused by a Corona Virus emerged with the 2003 Severe Acute Respiratory Syndrome (SARS) epidemic. The novel Corona Virus pneumonia (COVID-19), that emerged in the city of Wuhan, China; is an infectious acute respiratory caused by the novel Corona Virus. The virus is a positive-strand RNA virus with high homology to bats. Knowing that it has RNA in its genome helps us understand how we test for the presence of Corona Virus. The scientists analyzed the genetic template for spike proteins on this SARS-CoV-2, hooks on the outside of the virus that it uses to grab and penetrate the outer walls of human and animal cells. More specifically, they focused on two important features of the spike protein: The receptor-binding domain , a kind of grappling hook that grips onto host cells, and The cleavage site, a molecular can opener that allows the virus to crack open and enter host cells. 

After entering into the human body, it attacks on the 1-beta chain of hemoglobin. The attack will cause a huge reduction in amount hemoglobin that can carry oxygen and carbon dioxide, producing symptoms of respiratory distress. Virus attack damages many organs and tissues. Lung cells become toxic and inflammatory due to derivatives produced by the attack , which eventually results in dysfunction of lungs. As a result, causing death of an individual.

As the SARS-CoV-2 entered humans in its current pathogenic form from an animal source, it raises the probability of future outbreaks, as the illness-causing strain of the virus could still be circulating in the animal population and might once again jump into humans and leas to mass destruction. This Homo sapiens species needs to get prepared for these future outbreaks and prevent what is happening now.
