A closure of schools and universities, which were shut on March 14 for two weeks, will be extended for a further two weeks, Prime Minster Mostafa Madbouly said.
Most public services and government offices will close their doors to the public during the curfew period and a measure to limit the number of government employees going to work will be prolonged until mid-April.
The government has also allocated one billion Egyptian pounds ($63.69 million) to the health ministry to help it provide supplies, a statement from the cabinet office said.
Egypt has confirmed 366 cases of coronavirus, including 19 deaths, according to Reuters.
It has taken a series of measures to prevent the spread of the illness, including ordering all cafes, shopping malls, sports clubs and nightclubs to shut from 7 p.m. until 6 a.m. since March 19.
It has also grounded commercial flights and shut mosques and churches.
