Table

Plasmodium falciparum and P. vivax infections according to age groups of household members in study of P. vivax prevalence in semiarid region of northern Kenya, 2019*

Infection type Age range, y
<5, n = 490 6–15, n = 1,069 16–40, n = 1,324 >40, n = 318
Any Plasmodium sp. 166 (33.9) 368 (34.4) 397 (30.0) 98 (30.8)
P. falciparum only 151 (30.8) 344 (32.2) 373 (28.2) 92 (28.9)
P. vivax only 8 (1.6) 13 (1.2) 13 (0.98) 4 (1.3)
Mixed 7 (1.4) 11 (1.0) 11 (0.83) 2 (0.63)

*Values are no. (%) positive samples for each age group. Total number of samples tested was 3,305. However, 47 tested samples had missing age information, of which 20 were infected with P. falciparum and none with P. vivax; 57 samples were tested for P. vivax but not P. falciparum, of which none were positive for P. vivax. Therefore, the total number of samples in this table is 3,201. P. falciparum PCR methods and results are reported in (3).
