Saudi Arabia closed off air and sea travel to 14 countries affected by the new virus Monday, while Israel ordered two weeks of home quarantine for anyone arriving from overseas. Mideast stock markets tumbled over fears about the widening outbreak’s effect on the global economy. In Saudi Arabia, shares of state oil giant Saudi Aramco dropped 10 percent, forcing a halt to trading of the company on Riyadh’s stock exchange.

In the Mideast, there have been over 7,600 confirmed cases, with the vast majority in hard-hit Iran. The country’s health ministry said Monday the new virus killed another 43 people, pushing death toll to 237 amid 7,161 confirmed cases. Experts worry Iran may be under reporting its cases.

The drop in the markets came as global oil prices suffered their worst losses since the start of the 1991 Gulf War. Other Mideast markets fell as well as the new coronavirus has affected global energy prices and OPEC failed to make a production cut deal with Russia last week.

Saudi Arabia

Coronavirus concerns led Saudi Arabia on Monday to cut off air and sea travel with Bahrain, Egypt, France, Germany, Iraq, Italy, Kuwait, Lebanon, Oman, Spain, South Korea, Syria, Turkey and the United Arab Emirates. The kingdom had earlier closed off its land borders as well.

Abu Dhabi’s long-haul carrier Etihad, which operated 12 flights daily to Saudi Arabia, said three flights had been airborne at the time of the Saudi announcement. When those planes landed in Dammam, Jiddah and Riyadh, only Saudi citizens could disembark, with others having to return to Abu Dhabi, the airline said.

Saudi Arabia already shut down access to the holiest sites in Islam over concerns about the virus and the COVID-19 illness it causes. The virus usually leaves people with only mild to moderate symptoms, but because it’s new, experts can’t say for sure how far it will ultimately spread and how much damage it will do, both in terms of health and the global economy.

Separately, Saudi Arabia said it donated $10 million to the World Health Organization to help it combat the virus.

Israel

The outbreak in Israel has been largely contained, but it has begun to gain pace in recent days, with a total of 42 cases diagnosed. An additional 26 cases have been detected in the neighbouring West Bank.

Israel had earlier ordered residents returning from several European and Asian countries into 14 days of home quarantine. On Monday, Prime Minister Benjamin Netanyahu announced the measure would now apply to anyone entering the country from overseas.

“This is a difficult decision, but it’s necessary to protect public health. Public health comes before everything else,” Netanyahu said, announcing the decision after hours of consultations with senior Cabinet ministers, security officials and public health officials. He said the order would remain in effect for two weeks.

Moshe Bar Siman-Tov, director general of the Israeli Health Ministry, told Channel 13 TV that foreign tourists arriving on flights would have to show proof they have a place to stay for two weeks of home quarantine, or they would be barred entry. He said tourists already in the country should exercise caution and immediately contact authorities if they feel ill.

The move comes just ahead of the Passover and Easter holiday seasons, when Israel is flooded with overseas visitors. It was sure to deal another blow to the already struggling tourism industry. Netanyahu said the government, which has already approved a relief fund for hard-hit businesses, was working on other measures to protect the economy.

Qatar

The tiny, energy-rich neighbouring country of Qatar meanwhile has cut off travel to 15 nations including Bangladesh, China, Egypt, India, Iran, Iraq, Italy, Lebanon, Nepal, Pakistan, Philippines, South Korea, Sri Lanka, Syria and Thailand. That’s affected its long-haul carrier Qatar Airways, which has already been hurting from a years-long boycott by four Arab nations including Saudi Arabia over a political dispute.

Qatar separately announced via its state-run news agency it would shut down schools and universities beginning Tuesday until further notice.

Iran

In Iran, the judiciary’s Mizan news agency said authorities had temporarily released some 70,000 prisoners over concerns about the virus spreading in the country’s prisons, up from the 54,000 previously announced.

Bahrain

The island nation of Bahrain, which has seen 109 confirmed cases, ordered government officials not to travel abroad for two weeks.

Egypt

Meanwhile, authorities in Egypt’s southern tourist hub of Luxor announced the city would close to tourists Monday until medical experts could examine all hotel guests and cruise ship passengers in the area. Two cruise ships on the Nile River have been quarantined there in recent days.

Egypt’s prime minister also announced a temporary ban on large public gatherings and all events involving people’s movement between cities.
