| Seroprevalence data may indicate that many more than those who present with overt disease have latent melioidosis and may be at a risk of a relapse. |
| Andaman Islands is a highly endemic area for leptospirosis 4,5-8 with more than 50 per cent seroprevalence. |
| In endemic areas such as Africa, Asia, and South America there is a relatively high seroprevalence of antibodies to the organism. |
| If one assumes the inhabitants sampled were representative, the seroprevalence provides an estimate of surviving past or recent hantavirus infections in the area. |
| We conducted studies of hantavirus ecology in the Czech Republic and hantavirus seroprevalence in the Czech population. |
| In addition, because HIV infection was a risk factor for serious adverse reactions, incidence may be higher in populations with higher HIV seroprevalence. |
