Weill Cornell Medicine May 16 2025 Researchers at Weill Cornell Medicine have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body's immune system, sometimes for years. It turns out that the parasite, Plasmodium falciparum, can shut down a key set of genes, rendering itself "immunologically invisible." "This finding provides another piece of the puzzle as to why malaria has been so difficult to eradicate," said Dr. Francesca Florini,
