Italy remains the most COVID-19 affected country in Europe, having registered more than 147,000 cases and 18,000 deaths.
Current containment measures include non-essential travel restrictions, a ban on all non-essential activities and the closure of non-essential businesses.
Initially, the lockdown was to end on April 13, but Conte announced that it will now run until May 3.
As Italy extended the lockdown, some countries are mulling a gradual easing of the containment measures.
The World Health Organization (WHO) Director-General Tedros Adhanom warned countries against rushing to return to normalcy.
“I know that some countries are already planning the transition out of Stay Home restrictions. WHO wants to see restrictions lifted as much as anyone. At the same time, lifting restrictions too quickly could lead to a deadly resurgence. The way down can be as dangerous as the way up if not managed properly,” Tedros said in a briefing on Friday.
