The Magen David Adom rescue service on Thursday flew a first consignment of blood units to Peru after getting the green light from the Lima hospital that is looking after an Israeli traveler left in critical condition by a blood infection.

Zohar Katz, 21, from Kibbutz Yotvata in the southern Arava desert, has been lying sedated in the intensive care unit of the Lima hospital as doctors battle bacteria destroying her red blood cells.

Medical staff have been carrying out intensive dialysis on the young woman but need healthy blood supplies to replace the volumes they remove from her body.

An MDA paramedic, Yonat Daskal, flew with the 100 blood units and plasma and was set to join a senior hematologist from the organization who arrived in the Peruvian capital on Wednesday.

When Katz first fell seriously ill her family appealed via social media for Israelis in the South American country to donate blood.

Many answered the call, but the effort was hampered by strict regulations preventing those vaccinated within the previous six months from giving blood.

Hikers visiting South America usually have a bout of vaccinations three months before their trip.

MDA said said it would fly the necessary blood units to the hospital as soon as it overcame the tricky bureaucracy involved and obtained all the necessary permits.

MDA director general Eli Bin said Thursday, “The MDA doctor and paramedic who have been sent to Peru are doing everything in their power to look after Zohar.”

“We all hope that this will assist in stabilizing her condition, and eventually in bringing her back home.”
