Malaria is a major public health concern. Among the two most important causes of human malaria, Plasmodium vivax is the hardest to eliminate, owing largely to its ability to relapse (cause recurrent blood-stage infection following the activation of dormant liver-stage parasites called hypnozoites). Recurrent vivax malaria can also follow a failure to treat a preceding blood-stage infection (recrudescence) and, in endemic settings, a new infectious mosquito bite (reinfection). Understanding the cause of recurrent vivax malaria is critical for disease control efforts, e.g., to estimate the efficacy of a hypnozoiticidal drug, relapse needs to be separated from reinfection and recrudescence. In this report we describe the Pv3R statistical model designed to estimate using P. vivax genetic data the probability that a recurrent P. vivax blood-stage infection is a relapse, reinfection or recrudescence (the Pv 3Rs).

Matching journals

The top 6 journals account for 50% of the predicted probability mass.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
