Write an essay in 500 words on "Covid 19 :a warning bell
Answers
Answer:
COVID-19 could well be nature’s warning against climate change because microbes are the first to ring an alarm and this could just be the first wave of the pandemic with bigger outbreaks likely to follow.
The outbreak of coronavirus disease 2019 (COVID-19) has created a global health crisis that has had a deep impact on the way we perceive our world and our everyday lives. Not only the rate of contagion and patterns of transmission threatens our sense of agency, but the safety measures put in place to contain the spread of the virus also require social distancing by refraining from doing what is inherently human, which is to find solace in the company of others. Within this context of physical threat, social and physical distancing, as well as public alarm, what has been (and can be) the role of the different mass media channels in our lives on individual, social and societal levels?
Mass media have long been recognized as powerful forces shaping how we experience the world and ourselves. This recognition is accompanied by a growing volume of research, that closely follows the footsteps of technological transformations (e.g. radio, movies, television, the internet, mobiles) and the zeitgeist (e.g. cold war, 9/11, climate change) in an attempt to map mass media major impacts on how we perceive ourselves, both as individuals and citizens. Are media (broadcast and digital) still able to convey a sense of unity reaching large audiences, or are messages lost in the noisy crowd of mass self-communication? Do social media provide solace or grounds for misinformation, (de)humanization, and discrimination? Can we harness the flexibility and ubiquity of media technologies to increase the public's adherence to the safety measures suggested by global health organizations to combat the spread of COVID-19? How can different media industries and channels for mass communication promote adaptive responses to foster positive health attitudes and adherence to preventive measures? How media impact the dynamics in the private domain (e.g. strengthen family bonds versus domestic conflict and violence)?
An Essay on “Covid-19 Pandemic”
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.3
Modes of Transmission
It is proven that the virus is transmitted by airborne droplet infection and through contact with infected surfaces. Furthermore, although it has been demonstrated that the live virus has excreted from the human body through feces within 12 days of the onset of the disease, it has not been proven to be transmitted that way.3 The live virus has not been demonstrated in blood and urine and does not exhibit infectious properties. The disease is not transmitted by blood and blood products, or by mosquitoes or other bloodsucking parasites.4 Yet it is transmitted from person to person, and infectiousness begins even when the person who is sick has not yet developed symptoms.5 There is no consensus on the effects of climate and weather conditions on the contagiousness of the disease. There are scientific studies indicating that increased air temperature and humidity reduce the speed of propagation of the disease.6 However, some authors report that this would not be effective.4
