What is COVID-19? As COVID-19 a Real Threat to Human Life? Impacts of COVID-19 on Environment, Education, Internet Usage, Sports, and Mental Health of Human Beings Especially on Health Care Staff

In December 2019, a cluster of patients with pneumonia of unknown cause was linked to a seafood wholesale market in Wuhan, China and were admitted in hospital. The etiology was later verified as a novel, the coronavirus genus (2019-nCoV) and was subsequently named COVID-19 by the World Health Organization (WHO) on 11 February 2020. It is spread by human to human transmission via droplets or direct contact. Among patients with pneumonia caused by SARS-CoV-2 fever was the most common symptom, followed by cough, pain and runny nose. The disease rapidly spread all over the world and as of 5 August 2020, data from the World Health Organization (WHO) have shown that more than 18 354 342 confirmed cases have been identified in 213 countries/regions. America is currently at the top, followed by Europe. Based on the facts of an increasingly growing frequency of infections more than half of the global population is under some form of lockdown due to which decrease in environmental pollution takes place. Data released by NASA and ESA indicates that pollution in some of the epicentres of COVID-19 such as Wuhan, Italy, Spain, South Korea and USA, etc. has reduced up to 30%. COVID-19 inhibits the process of learning due to which millions of students and teachers were affected across the globe. The introduction of an online learning system has brought significant improvements in learning of the students. The responses to online education vary widely depending on the level of income. Due to COVID-19 Internet traffic is 25 to 30 percent higher than the average, which has a significant effect on in-house social media consumption worldwide and gives a big boost to apps. It is also a major source of fear, stress and anxiety as well as a main element affecting people’s health globally, especially of health carrying a staff which suffered more avoidance behaviours than the general public, and it leads them to sadness and depression. Misinformation and misleading facts from local news sources, lack of daily routine, decrease of social and physical interaction cause severe stress. The COVID-19 global epidemic impacted the sports industry badly. Many professional leagues all around the world banned their seasons and events have been rescheduled, which cause a huge loss to the economy
