Coronavirus disease 2019 (COVID-19) is an outbreak of epidemic disease origin in Wuhan city, China. The virus transmits rapidly in worldwide and the rate of fatality also elevated by passing each day. But, action taken by World Health Organization failed to stop outbreak of COVID-19. Wuhan city in China has controlled the pandemic disease with lockdown strategy and present all other countries also followed the same strategy for a month. Hence, present study has been designed to observe the impact of lockdown on COVID-19 in worldwide population and future prophecy with present circumstances. Online database ( www.channelnewsasia.com) was used to ensure that number of COVID-19 cases, death and recovery are recorded in the period of 20 days lockdown (6th - 26th April 2020) in worldwide and as well as country wise population. The data shows significant elevation of COVID-19 cases was observed since 71447, on Feb 18th to 1.3 million by 6th April and then to 2.96 million by 26th April 2020 in worldwide. The fatality rate of COVID-19 were shown to be increased from 2.48% on Feb 18th to 5.51% by 6th April and then to 6.95% on 26th April 2020 in worldwide. We have found increased morbidity (2.21 folds) and fatality (6.95%) of COVID-19 in worldwide and country wise population. In fact lockdown might help to reduce register new cases, but not made zero. However, present situation demands continuation of lockdown and social distance should be maintained with strict rules otherwise probabilities are more to reach unimaginable number of cases in coming days.
