Mirrored: Argentina has extensive medical experience with ivermectin. Before the COVID-19 pandemic, it was used to treat dengue fever, which is endemic in Argentina.
Early in the pandemic, Dr. Hector Carvallo, a retired medical professor in Argentina, devised two ivermectin trials to assess the drug’s usefulness against SARS-CoV-2. His treatment protocols are used in five Argentinian provinces. In one province, the death rate was reduced to one-third in less than a month, in the middle of the outbreak.
When used preventatively, ivermectin is administered in conjunction with carrageenan, which also has antiviral properties.
When treating mild cases, ivermectin is administered with aspirin; in moderate cases with aspirin and corticosteroids, and in severe cases, ivermectin is given with enoxaparin, an anticoagulant drug.
These drug combinations were selected based on what was known about other viruses that cause similar health effects as SARS-CoV-2, such as the rhabdovirus’ effect on neurology, the paramyxovirus, which causes hyperinflammation in the lungs, and the dengue virus, which overamplifies the immune system.
