Abstract: The first confirmed victim of COVID-19 in Sri Lanka was identified in the latter part of January 2020. There was no vaccine in the world for COVID-19 at that time, the Government of Sri Lanka encouraged the people to strictly adhere to the social distancing to prevent the decline of the public health sector like other countries, for the prevention of the second wave, and to control the spread of the disease. Similar to all other countries, the Government of Sri Lanka either abandoned or postponed all important events, ordered all educational activities including schools and universities to be closed and controlled the operation of workplaces in the state and private sectors, and implemented work from home. From mid-March to June 2020 strict lockdown operations were carried out in Sri Lanka. On March 20, 2020, a nationwide police curfew was imposed without an emergency order, and inter-district travel was also soundly restricted.
