A Study on the Impact of Covid-19 on Students Learning Experiences with Special Reference to Madurai City
Corona viruses are a large family of viruses, causing less severe common cold to more severe diseases such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). The SARS-CoV-21 is a corona virus very similar to the one that caused SARS. There is evidence that the SARS-CoV-2 has also been transmitted from bats. Like other corona viruses, SARS-CoV-2 virus particles are spherical and have mushroom-shaped proteins called spikes protruding from their surface, giving the particles a crown-like appearance. The spike binds and fuses to human cells, allowing the virus to gain entry. Researchers at the University of Texas at Austin and the National Institutes of Health, U.S., have produced a 3D atomic-scale map of the protein of the SARS-CoV-2 that binds to and infects human cells. Mapping the 3D structure of the protein - spike (S) glycoprotein - will allow a better understanding of how the virus binds to the human cells. Knowing the structure of the spike protein will, in turn, allow scientists to develop vaccines and antivirals against the virus and even better diagnostics. The World Health Organisation has declared COVID-19 to be a pandemic4. The symptoms of COVID-19 appear within two to 14 days after exposure and include fever, cough, a runny nose and difficulty in breathing. This paper provides a comprehensive review of the COVID-19 and how this great pandemic has bothered the ordinary life of every citizen, with more focus on the economic imbalance created in India. This study has also attempted to know the students learning experiences and their attitude due to this lockdown period amidst the demanding end of the semester requirements in the year 2020. It also attempts to know their expectations, anxieties, plans and problems encountered by them about COVID-19 by being at home, having in mind their career development.
