The paper's results, published August 8 in Cureus, found a 74 percent reduction in excess deaths in 10 states with the most intensive ivermectin use over a 30-day period following peak deaths during the pandemic. When analyzing data across 25 states in Peru, researchers found these reductions in excess deaths correlated closely to ivermectin use during four months in 2020.

When ivermectin was available without restriction, there was a fourteenfold reduction in nationwide excess deaths. Once access to ivermectin was restricted by the government, a thirteenfold increase in excess deaths was observed in the two months following the limitation of its use. The findings align with summary data from the World Health Organization for the same time period in Peru.

Ivermectin is a widely-known and inexpensive treatment against parasitic diseases. Scientists believe the drug can also bind to the spike protein of the SARS-CoV-2 virus, limiting its morbidity and infectivity.
