From: Determinants of relapse periodicity in Plasmodium vivax malaria
In infections of volunteers with the St Elizabeth strain of P. vivax[71], there was no evident relationship between the occurrence or duration of the primary illness and the long-latency interval before illness (left panel), whereas there was an inverse relationship between sporozoite inocula (assessed semi-quantitatively from sporozoite numbers in the salivary glands and number of infectious bites) and the latency interval.
