Table 1.
The table illustrates the prevalence of Human T-lymphotropic virus type I (HTLV-I) in various cohorts, as well as the percentage of HTLV-I Western blot (WB) seroindeterminates in the respective cohort and the percentage of these seroindeterimates that were HLTV-I PCR positive.
| Country [Reference] | Number Screened | HTLV-I EIA Reactive | HTLV-I WB + (% of Total EIA Reactive) | HTLV-II WB + (% of Total EIA Reactive) | WB Seroindeterminate (% of Total EIA Reactive) | * HTLV-I PCR + (% of WB Serondeterminates) |
|---|---|---|---|---|---|---|
| Argentina [17] | 86,238 | 0.17% | 20% | 8.0% | 61% | 13.8% |
| Brazil [19] | 351,639 | 1.22% | 24% | Not Shown | 52.2% | 9.2% |
| Iran [17] | 79,687 | 6.4% | 50.7 % | 3.1% | 25.4% | 12.5% |
| Taiwan [35] | 1,122,879 | 0.1% | 41% | 1.0% | 22% | Not Shown |
| US [36] | 267,650 | 0.89% | 3% | Not Shown | 16% | 0.00% |

PCR results were obtained from a subset of WB Indeterminate samples for each cohort, as all samples were not available for further analysis.
