The dissolved oxygen (DO) values were found to 6.8 mg/ml from 3.8 mg/ml which is an improvement of 79%. As per the data of the Central pollution control board (CPCB's) out of 36 various points of the Ganga river, the 27 points are found suitable for the propagation of wildlife and Fisheries. The COVID-19's gift to Ganga was seen within 10 days of nationwide lockdown. During the lockdown period, the Ganga water quality improved remarkably. It has been noticed that over a month in this lockdown, air and water pollution have been declined. So, in the throes of adversity, yet there is a reason to celebrate in COVID-19. The curve can be flattened by social distancing and this has been an incidental boon to the environment.

Social lockdown is considered the most effective measure to control COVID-19 ( Das and Patial, 2020 Paital et al., 2020). Since there is no effective antiviral medicines or vaccine is investigated until now so the most effective way to protect our self by social distancing. However, some traditional or home remedies may improve our resistance power for dealing with this virus. Although there is no evidence that the above-proposed medicine can prevent or cure the disease surely. 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 ( Gautret et al., 2020 Colson et al., 2020 Zhonghua, J. As virus spreads COVID-19 so antibiotics do not work. 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). The symptoms of this disease are dry cough, fever, difficulty in breathing.

So it is very important to maintain a distance of around 1 m (3 ft) away from person who is sick. By touching these droplets present on the surface around the person with COVID-19 is a strong reason for catching this disease. The main spreading way of this virus is through respiratory droplets expelled by the person suffering from cold and cough. The virus of COVID-19 is transmitted through contact with respiratory droplets instead of air. The effect of the virus is an acute lung jury and respiratory distress syndrome that ultimately causes pulmonary failure and causes a fatality. Its size ranging from 65 to 125 nm in diameter. The virus having crown like spikes on the outer surface of it that's why we called as corona virus. The SAR-COV is a member of the β-coronavirus sub-group from coronaviridae family ( Pyrc et al., 2007). Again, this virus has not previously seen in humans so it is also called “Novel corona virus”. This disease is the first time introduce in the year of 2019 that is why it is called COVID-19. In the name of the disease COVID-19, CO stands for ‘Corona’, VI stands for ‘Virus’ D stands for ‘Disease’. World Health Organization gave the name of the disease as COVID-19 on Feb 11 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 (WHO) in 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). A second outbreak was in 2012 in Saudi Arabia as Middle East respiratory syndrome (MERS). 2003 was the first known year of SARS illness caused by coronavirus in China as acute respiratory syndrome. 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). COVID-19 is a new dangerous infectious disease that causes illness in animals or humans.
