The findings described in the two case reports of malaria on pages 8 to 9 of this issue of the MSMR illustrate what has been previously reported about the frequently prolonged latent period between exposure to Korean strains of Plasmodium vivax and the subsequent clinical presentation with overt malaria see pages 8-14.1 Both cases experienced delays of at least fi ve months since leaving Korea and as long as 10 months since their likely exposure to malaria vectors before the onset of their symptoms. Review of their electronic health records uncovered no evidence of prior clinical symptomatology consistent with malaria. Th e length of the latency period may have some basis not only in the strain of P. vivax, but also in the relative youth and general excellent physical condition of these two soldiers. Moreover, it is possible that mild symptomatology was not reported by the soldiers or observed in clinic.
