On Sept. 20, 2022, the University of California, Davis announced that the amphibian decline in Latin America in the 1980s and 2000s had direct health consequences for people.

The study, published in the journal Environmental Research Letters, links an amphibian die-off in Costa Rica and Panama with a spike in malaria cases in the region. At the spikeﾒs peak, up to 1 person per 1,000 annually contracted malaria that normally would not have had the amphibian die-off not occurred, the study found.
