For all their fear mongering about ivermectin, the CDC recommends giving ivermectin to refugees for parasites:
“All Middle Eastern, Asian, North African, Latin American, and Caribbean refugees should receive presumptive therapy with:
Albendazole, single dose of 400 mg (200 mg for children 12-23 months)
AND
Ivermectin, two doses 200 mcg/Kg orally once a day for 2 days before departure to the United States.
All African refugees who did not originate from or reside in countries where Loa loa infection is endemic (Box 1) should receive presumptive therapy with:
Albendazole, single dose of 400 mg (200 mg for children 12-23 months)
AND
Ivermectin, two doses 200 mcg/Kg orally once a day for 2 days
AND
Praziquantel, 40 mg/kg, which may be divided in two doses before refugees depart for the United States.”
