Essay on corona virus 500 words
Answers
Answer:
Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans, these viruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS, and COVID-19. Symptoms in other species vary: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are as yet no vaccines or antiviral drugs to prevent or treat human coronavirus infections.
Coronaviruses constitute the subfamily Orthocoronavirinae, in the family Coronaviridae, order Nidovirales, and realm Riboviria. They are enveloped viruses with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 26 to 32 kilobases, one of the largest among RNA viruses. They have characteristic club-shaped spikes that project from their surface, which in electron micrographs create an image reminiscent of the solar corona, from which their name derives.
Etymology
The name "coronavirus" is derived from Latin corona, meaning "crown" or "wreath", itself a borrowing from Greek κορώνη korṓnē, "garland, wreath". The name was coined by June Almeida and David Tyrrell who first observed and studied human coronaviruses. The word was first used in print in 1968 by an informal group of virologists in the journal Nature to designate the new family of viruses. The name refers to the characteristic appearance of virions (the infective form of the virus) by electron microscopy, which have a fringe of large, bulbous surface projections creating an image reminiscent of the solar corona or halo. This morphology is created by the viral spike peplomers, which are proteins on the surface of the virus.

The unprecedented COVID-19 pandemic spread rapidly across nations and country after country responded with lockdowns, making about 1.5 billion students globally remain at home.
Under these circumstances, and in order to engage students in a constructive reflection on current and forthcoming challenges, UNESCO and Takhte have organized a rolling essay contest entitled ‘Year 1 AC (After Coronavirus): Pan India Online Essay Contest 2020’. Children (aged 11–14 years) and youth (aged 15–24 years) have been invited to unleash the power of writing to combat isolation and stimulate creativity.
During the first month since its launch, hundreds of young participants from across 24 states in India shared their meaningful and provoking thoughts through their essays. As of mid-May, more than 500 submissions were received, from children and youth, ranging from 11 to 24 years. Participants - notably young women accounting for over 67% of the submissions under the Youth category, have voiced their concerns about life after the coronavirus, especially on gender roles and stereotypes.
The contest has captured Indian young people’s desire to express their thoughts during this period, visualizing the future they would like to build after the coronavirus fades away.
Following a thorough screening process, 35 winning essays have been showcased through the UNESCO website and social media channels. Each of the essays has something new and important to say. Here is what some of the young writers had to say
