A spike in cases in the Gulf helped push infections in the Middle East for the novel coronavirus past 10,000 cases on Thursday, with most infected people either in Iran or having recently traveled there.
Countries in the region have imposed varying levels of restrictions on travel, from the wholesale halting of all commercial flights in Kuwait, to Saudi Arabia banning travel to 39 countries.
Regional stock markets were down, reflecting investor concerns and nerves felt worldwide as oil prices plunge and tourism revenue is eroded by the virus. The World Health Organization on Wednesday officially designated the outbreak as a "pandemic."
Multiple top officials in Iran - from its senior vice president to Cabinet ministers, members of parliament, Revolutionary Guard members, health workers and health ministry officials - have contracted the virus. Some of those officials have died.
Iran says the virus has killed 354 people and infected some 9,000 people nationwide. There are concerns that the number of infections across Iran is much higher than the confirmed cases reported by the government, which is struggling to contain or manage its spread. The rising casualty figures each day in Iran suggest the fight against the novel coronavirus is far from over.
For most people, the coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The vast majority of people recover from the virus and the COVID-19 illness it causes.
There is still no vaccine available for the pathogen, so countries are implementing tough measures to restrict its spread, as well as the impact an outbreak could have on emergency rooms and intensive care units.
This week, Qatar reported a massive jump in the number of people who have tested positive for the virus late Wednesday with 262 now infected. More than 200 new cases had been found in people under quarantine.
In the Gulf Arab island nation of Bahrain, confirmed cases also rose by nearly 70% this week to 189 confirmed cases, after 77 new cases were confirmed on a flight returning from Iran.
Kuwait on Thursday closed all workplaces and non-essential businesses for two weeks, including restaurants, cafes and health clubs. Schools and universities have already been suspended. All commercial flights are being halted to Kuwait starting Friday. The country has over 70 confirmed cases.
Saudi Arabia, meanwhile, has also announced a surge in the number of cases from 21 to 45 late Wednesday, among them 12 Egyptians under quarantine in Mecca. The government has suspended pilgrimage to Islam's holiest sites, barring entry of all pilgrims to Mecca and Medina to curb the spread of the virus. It has also cordoned off the eastern province of Qatif, where more than a dozen cases are confirmed among its mostly Shi'ite population from people who recently visited Iran.
Iran has one of the world's highest death tolls outside of China, the epicenter of the outbreak. Outside of Iran, only Iraq, Egypt, and Lebanon have recorded deaths from the virus in the Middle East.
