As all the types of social, economic, industrial and urbanization activity suddenly shut off, nature takes the advantages and showed improvement in the quality of air, cleaner rivers, less noise pollution, undisturbed and calm wildlife. This research aims to discuss the COVID-19 effect on the global environment. The outcome of this research SAYS that “Although coronavirus vaccine is not available coronavirus itself is earth's vaccine and us humans are the virus”.Keywords: COVID-19, Lockdown, Environmental impact, Air quality index, Pollution, WildlifeGraphical abstractUnlabelled Image1. IntroductionCOVID-19 is a new dangerous infectious disease that causes illness in animals or humans. History provides a record of epidemics such as plague, smallpox, measles, cholera, influenza, Ebola, AIDS, severe acute respiratory syndrome (SARS) and now COVID-19 (David, 2020). 2003 was the first known year of SARS illness caused by coronavirus in China as acute respiratory syndrome. A second outbreak was in 2012 in Saudi Arabia as Middle East respiratory syndrome (MERS). World Health organization (WHO) in Dec 31, 2019 named it SARS-COV-2 and the disease as COVID-19 (Cui et al., 2019; Lai et al., 2020; Peiris et al., 2004; WHO, 2020). Genetically the virus of COVID-19 and Severe Acute Respiratory Syndrome (SARS) are related to each other but disease caused by them is quite different.World Health Organization gave the name of the disease as COVID-19 on Feb 11 2020. In the name of the disease COVID-19, CO stands for ‘Corona’, VI stands for ‘Virus’ D stands for ‘Disease’. This disease is the first time introduce in the year of 2019 that is why it is called COVID-19. Again, this virus has not previously seen in humans so it is also called “Novel corona virus”. The SAR-COV is a member of the β-coronavirus sub-group from coronaviridae family (Pyrc et al., 2007). The virus having crown like spikes on the outer surface of it that's why we called as corona virus. Its size ranging from 65 to 125 nm in diameter. The effect of the virus is an acute lung jury and respiratory distress syndrome that ultimately causes pulmonary failure and causes a fatality. The virus of COVID-19 is transmitted through contact with respiratory droplets instead of air. The main spreading way of this virus is through respiratory droplets expelled by the person suffering from cold and cough. By touching these droplets present on the surface around the person with COVID-19 is a strong reason for catching this disease. So it is very important to maintain a distance of around 1 m (3 ft) away from person who is sick. The symptoms of this disease are dry cough, fever, difficulty in breathing. Infants, older people and those with medical problems like high B.P., cancer, diabetes, heart problem, asthma are more prone to DEVELOP this disease (Arabi et al., 2019; Ashour et al., 2020; Dong et al., 2020; Zhou et al., 2020). As virus spreads COVID-19 so antibiotics do not work. Without much clinical experience, some already medicines such as hydroxychloroquine, azithromycin, lopinavir, ritonavir, corticosteroids, paracetamol, ibuprofen and certain nucleotide are proposed for the treatment of COVID-19 |
