Answers
Answer:
COVID-19, caused by novel coronavirus SARCoV2, is a contagious disease, emerged in the end of December 2019, at Wuhan seafood market, China. This disease is spiraling like a wildfire and rapidly spreading worldwide, overburdening the health system with newly infected cases. As of April 25, 2020, a total of 2,846,536 COVID-19-positive cases and 197,859 total deaths were reported across the globe. This epidemic has exponential growth characteristics in the absence of specific vaccine and treatment for COVID-19. Many countries across the world including India, the USA, China, Italy, and German are implementing the lockdown measures to control the COVID-19 pandemic and to maintain the infection at manageable levels. Keeping the prospectus of future such pandemics, we reviewed; what is lockdown and containment? Does it works? What are the advantages of lockdown and containment in cotrolling the spread of the virus?. The present review answers these questions and tries to spread light on the impact of lockdown. Our review concludes that the implementation of lockdown has forced many countries in flattening the epidemic curve and strengthening the health-care system and improves the environmental quality during the COVID-19 pandemic.

The clinical characteristic of this disease was very much similar to viral pneumonia. Analysis on case samples by the Chinese Center For Disease Control and Communication (CDC) officially declared that pneumonia was caused by novel coronavirus and named it as novel coronavirus pneumonia.[1] Later on January 7, 2020, the World Health Organization (WHO) officially named it as COVID-19. Novel coronavirus belongs to a large family of viruses, family Coronaviridae and subfamily Coronavirinae.[2] According to the WHO, COVID-19 belongs to Group 2 of betacoronavirus, which is similar to severe acute respiratory syndrome coronavirus (SARS-CoV) widespread of 2002–2003 and Middle East respiratory syndrome coronavirus (MERS-CoV) epidemic in 2013–2015. Despite both COVID-19 and SARS-CoV belong to betacoronavirus subgroup.[3] Initially, cases of COVID-19 reported that it may be less severe than SARS and MERS, but later, the virus was transmitting rapidly from human to human, and evidence suggested that novel coronavirus is more a infectious disease than SARS-CoV and MERS-CoV.[4],[5]
COVID-19 is a respiratory disease,[6] which affects many people in different ways, and infected people will get mild-to-moderate symptoms, usually seen after 2–14 days. Common symptoms include fever, cough, sneezing, runny nose, sore throat, exacerbated asthma, and diarrhea.[7] The National Institutes of Health reported that young children, people above 60 years or older, pregnant women, and people underlying disease conditions have a higher risk of getting infected with the disease and prone to mortality. Respiratory infections usually transmit from person to person through droplets varying of different sizes, when the diameter of droplet size >5 μm is called respiratory droplets and <5 μm is called droplet nuclei.[8] According to the WHO, the spread of coronavirus is basically through respiratory droplets and contacts
