  • Background: Malaria re-emerged in Greece since 2009 after >35 yrs, with locally acquired P. vivaxcases. A malaria outbreak was detected in 2011 in Lakonia (36 local cases) with an additional 10 locally acquired cases in 2012. Public health measures were implemented including Proactive Case Detection (PACD) with fever screening, with Reactive ACD in the event of any malaria case, Indoor Residual Spraying (IRS), distribution of Long-lasting insecticide treated Nets (LLINs) and targeted mass antimalarial drug administration (tMDA) to migrants from malaria endemic countries living in the area.

    Methods: An empiric antimalarial course of chloroquine and primaquine was selected targeting P. vivaxhypnozoites after consultation with an intersectoral working group of experts. tMDA was implemented by field teams(1-2 health professionals and a mediator), providing the medicines for free daily under Directly Observed Therapy (DOT). Administration followed a mediator obtained informed consent and G6PD testing. Adverse effects were monitored daily in a structured pharmacovigilance form.

    No haemolysis

    17 migrants in 2013 and 5 in 2014 had moderate or severe G6PD deficiency and were not offered the treatment.

    Conclusion: No cases of P. vivax malaria, locally acquired or imported, were detected in Evrotas either 2013 or in 2014. tMDA proved a safe public health measure, which in combination with the other interventions controlled the re-emergence of malaria in this focus in Greece.
