AMMAN, Jordan (AP) — The UN refugee agency said on Tuesday it has confirmed two coronavirus cases in the Azraq camp for Syrian refugees in Jordan, which is home to more than 36,000 people who have fled their country’s civil war.

They are the first infections to be detected among Syrians living in refugee camps in Jordan. The UNHCR said the two patients have been transferred to quarantine facilities and their neighbours have been isolated as more testing is carried out.

More than 5.5 million Syrians have fled the country since the war broke out in 2011, with most settling in neighbouring countries where they often live in close quarters and struggle to make ends meet. Coronavirus lockdowns have taken a heavy toll on the region’s economies, making it even harder for refugees to find work.

Azraq is home to some 36,000 Syrian refugees, while the larger Zaatari camp in Jordan houses around 80,000. Jordan hosts a total of more than 650,000 Syrian refugees, most of whom live outside of camps. At least four Syrian refugees living outside the camps in Jordan have tested positive, with three of them recovering.

“This is the first confirmed case of coronavirus in refugee camps in Jordan,” the UNHCR said in a statement. “It is a reminder that everyone has been affected by this epidemic, and solutions must be addressed through international solidarity and cooperation.”

Experts and aid agencies have warned of potentially catastrophic outbreaks in the world’s refugee camps, where sanitation is often poor and social distancing is nearly impossible. Over 70 million people worldwide have fled their homes because of war and unrest, and up to 10 million live in refugee camps and informal settlements.
