Gaza has reported its first cases of Covid-19 in the general population, as authorities confirmed four infections at a refugee camp and security forces declared a full lockdown for 48 hours. The first cases of coronavirus have been detected outside of quarantine facilities within the Gaza Strip, Palestinian officials have announced, a potentially disastrous development given the enclave’s fragile health system.
The four cases were from a single family, according to a government statement. Four people from the same family have so far tested positive for coronavirus, Gaza’s interior ministry said as authorities imposed a 48-hour lockdown.
The closure will affect the entire Gaza Strip, according to an official from Hamas, the Islamist group that rules the territory. “As soon as the virus cases were detected, the leadership of the interior ministry and the crisis unit held intensive meetings. It is currently in session and closely following all the details,” said interior ministry spokesman Iyad al-Bazam.
Until Monday the 360 sq. km. coastal strip, which is home to two million Palestinians living in densely packed cities, towns and refugee camps, had reported no infections outside quarantine centres set up for people returning home from abroad. Hamas authorities urged Gazans to abide by the immediate shutdown, which includes the closure of workplaces, schools and mosques.
Gaza has been under a crippling Israeli blockade since 2007 and access to the enclave was further restricted following the onset of the coronavirus pandemic. Those granted permission to enter the strip have been held in special quarantine centres for three weeks.
There have been 109 coronavirus infections registered among those quarantined, with one death, according to the latest figures from the World Health Organization.
The arrival of coronavirus among the broader population in Gaza, a densely-populated area home to two million Palestinians, has been feared for months.
Suhair Zakkout, a spokeswoman for the ICRC in Gaza, said a coronavirus outbreak would be “catastrophic”.
“The health system is already weakened by the restriction of movement, lack of financial resources, and the Palestinian internal differences,” she told the Guardian.
Gaza is currently facing severe power shortages after Israel cut off fuel supplies in response to incendiary balloons being flown across the frontier, which have set farmland ablaze.
Rockets have also been fired from the enclave this month and the Israeli army has repeatedly struck Hamas targets, sparking concerns of a military escalation.
