This comes as an addition to the existing travel warning to China, where the virus originated.

The ministry will conduct an official meeting later Sunday regarding the new preventive measures.

The Foreign Ministry slammed the new precautions on Sunday, calling them "unprecedented diplomatic damage."

"The Ministry of Health is causing unprecedented political damage," said an official in the ministry. "Israel is the first in the world to take such a step."

Last Friday, the ministry announced that anyone returning from the countries included in the extended warning is obligated to refrain from appearing in public spaces for 14 days and returning travelers who show possible symptoms are required to arrive immediately to the closest clinic or hospital.

Anyone who answers to the following criteria - was in contact with someone who is a confirmed patient of the coronavirus, visited one of the listed countries in the last two weeks, has a temperature of above 38 Celsius (100 Fahrenheit), cough, heavy breathing or any other respiratory symptom - is required to report in order to get tested.

China raised the death toll from its coronavirus outbreak to 811 on Sunday, passing the number killed globally by the SARS epidemic, as authorities made plans for millions of people returning to work after an extended Lunar New Year break.

Also on Sunday, Israel's flag carrier El Al Airlines has decided to cancel its flights to Hong Kong this week, following the outbreak of the deadly pathogen. The last flight will depart Sunday night. This follows a similar flight ban imposed by the national air service on flights to Beijing last month.

Many of China's usually teeming cities have almost become ghost towns during the past two weeks as Communist Party rulers ordered virtual lockdowns, canceled flights and closed factories and schools.

Even on Monday, many workplaces and schools will remain closed and many white-collar employees will work from home.
