New relapse paper published in Malaria Journal
A new SEEG paper, Geographical variation in Plasmodium vivax relapse by KE Battle et al published in Malaria Journal, provides a comprehensive assessment of the evidence of P. vivax relapse weeks to months after initial infection.
The results indicate that relapse periodicity varies systematically by geographic region and are categorized by nine global regions characterized by similar malaria transmission dynamics. This indicates that relapse may be an adaptation evolved to exploit seasonal changes in vector survival and therefore optimize transmission.
This research will inform clinicians treating individual infections, epidemiologists trying to infer P. vivax burden, and public health officials trying to control and eliminate the disease in human populations.
