Query: Effect of Lockdown on the spread of COVID-19 in Pakistan   A novel coronavirus originated from Wuhan, China in late December 2019 has
now affected almost all countries worldwide. Pakistan reported its first case
in late February. The country went to lockdown after three weeks since the
first case, when the total number of cases were over 880. Pakistan imposed a
lockdown for more than a month which slowed the spread of COVID 19 effectively,
however in late April relaxation in lockdown was allowed by the government in
stages to lift the strain on the economy. In this study, the data has been
analyzed from daily situation reports by the National Institute of Health
Pakistan and the effects of initial strict lockdown and later smart lockdown
have been studied. Our analysis showed a 13.14 Percentage increase in cases
before lockdown which drops down to 6.55 percent during the lockdown. It proved
the effectiveness of lockdown. However, the Percentage Increase in case grows
up to 7.24 during a smart lockdown. If it continues to rise in this manner,
Pakistan may need to enter again into a strict second lockdown.
