Plasmodium vivax congenital malaria in an area of very low endemicity in Guatemala: implications for clinical and epidemiological surveillance in a malaria elimination context

Table 1 Plasmodium vivax parasitaemia and molecular results from the different compartments and time points

	At birth					21 days after birth
	Mother at delivery	Cord	Placenta		Newborn	Newborn
			Impression smear	Histology
Microscopy (parasites/μL blood)¹	6429	50	Not assessable	No parasites nor malaria pigment	Negative	2079
RT-PCR^2,3	+	+	+	Not available	Negative	+

¹ Parasitaemia density was estimated using the patients white blood count.
² RT = Real-time PCR: + presence of P. vivax DNA.
³ Molecular analyses were carried out after the detection of the congenital malaria case in hospital. All samples at delivery (maternal, cord, placental and newborn blood) and during admission (newborn) were tested for P.falciparum (microscopy and real-time PCR) and were negative.
