Addressing media persons, Khan said: "The coronavirus cases are expected to increase from May 15 to May 20. The hospitals as we were predicting earlier would have been under pressure April 15 onwards. However, that has moved forward by a month to May 15."
He also said that a bigger crisis of coronavirus was averted due to the lockdown that the government initiated mid-March.
He said: "50,000 cases were expected by April 25, but we were saved from the disaster as we implemented lockdown in March when there were only fewer cases in the country."
Prime Minister Khan also stressed that unemployment and hardships of daily wage labourers remain a challenge for his government.
"The biggest problem is that labour workforce is not registered in our country," he said.
"The government opened the construction industry to protect people from unemployment and hunger," he said.
