Table 2. Characteristics of the Plasmodium-infected individuals in both groups (symptomatic and asymptomatic) .
| Symptomatic N=104 | Asymptomatic N=37 | Total N=141 | p value* | |

| Female (%) | 30 (28.8) | 07 (19) | 37 | |
| Number of previous malaria episodes** | 20 (0-20) | 15 (0-20) | 20 (0-20) | 0.0123 |

| Detectable | 60 | 9 | 69 | 0.0005 |
| Non-Detectable | 44 | 28 | 72 | |
| Plasmodium species | ||||
| P. falciparum | 38 | 9 | 47 | |
| P. vivax | 34 | 15 | 49 | |
| P. malariae | 0 | 2 | 2 | |
| P. falciparum and P. vivax | 32 | 11 | 43 |
Age and number of previous malaria episodes were expressed as median (minimum-maximum). *Statistical significance was determined by Mann Whitney and Chi square tests. **All subjects that reported more than 20 malaria episodes were arbitrarily designated as having 20, this is the reason the maximum value of the number of previous malaria episodes was 20 in either symptomatic and asymptomatic groups.
