The COVID-19 pandemic is considered as the most crucial global health calamity of the century and the greatest challenge that the humankind faced since the 2nd World War. In December 2019, a new infectious respiratory disease emerged in Wuhan, Hubei province, China and was named by the World Health Organization as COVID-19 (coronavirus disease 2019). A new class of corona virus, known as SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) has been found to be responsible for occurrence of this disease. As far as the history of human civilization is concerned there are instances of severe outbreaks of diseases caused by a number of viruses. According to the report of the World Health Organization (WHO as of April 18 2020), the current outbreak of COVID-19, has affected over 2164111 people and killed more than 146,198 people in more than 200 countries throughout the world. Till now there is no report of any clinically approved antiviral drugs or vaccines that are effective against COVID-19. It has rapidly spread around the world, posing enormous health, economic, environmental and social challenges to the entire human population. The coronavirus outbreak is severely disrupting the global economy. Almost all the nations are struggling to slow down the transmission of the disease by testing & treating patients, quarantining suspected persons through contact tracing, restricting large gatherings, maintaining complete or partial lock down etc. This paper describes the impact of COVID-19 on society and global environment, and the possible ways in which the disease can be controlled has also been discussed therein.
Answer:
Coronavirus
Some mutated species of the Coronavirus family, which is commonly accepted as a disease agent in animals, can also cause diseases in humans. We have witnessed examples of this as SARS in 2002 and MERS in 2011, both of them being severe lower respiratory tract infections. The causative pathogen of the disease, which has become a pandemic (a worldwide epidemic) today, is named the SARS-CoV2 virus, and the disease it causes is COVID-19. It causes serious lower respiratory failure, as in previous examples, and may damage the central nervous system in the early period, unlike the previous ones.1 Like other members of the Coronavirus family, this virus has a sheath called the envelope in its fat structure, which has spiky protrusions of its protein structure on its outer surface. Because it looks like a “crown” due to these spiky protrusions, it is referred to as “corona”, meaning crown (figure). The spiky proteins of the SARS-CoV2 virus differ from the SARS virus by 2% and provide much better adhesion to human cells.2 The virus is a non-living pathogen agent with its nucleic acid chain (a kind of helical amino acid chain that carries genetic codes) in the envelope. The virus can replicate itself, cause damage, and spread only when it infiltrates into another cell. For the SARS-Cov2 virus to infiltrate into cells, its envelope structure must be strong. The virus becomes harmless as oil solvents such as soap or detergent damage the envelope structure. It can remain infectious for only a few days if it cannot infiltrate into the cell provided that its envelope structure is strong. The exposed virus is deformed over time and becomes ineffective. When a sufficient number of SARS-CoV2 enters the human body, the infection begins once the virus clings onto the surface epithelium (a skin-like but much thinner, a single layer of cell covering the inner cavities of our body) and then infiltrates the cell.
