Brief summary
Nonhuman primates (NHPs) constitute an important reservoir of infectious agents, some of which have emerged in human populations as deadly pathogens. Human exposure to the biological fluids of NHPs - particularly through bites - can result in the transmission of several viruses. Only the rabies virus is currently targeted by post-exposure prophylaxis following an injury caused by an NHP. The objective of the study is to investigate the prevalence of STLV-1 and SFV infections following a nonhuman primate bite.
Detailed description
Nonhuman primates (NHPs) constitute an important reservoir of infectious agents, some of which have emerged in human populations as deadly pathogens. Human exposure to the biological fluids of NHPs - particularly through bites - can result in the transmission of several viruses. Only the rabies virus is currently targeted by post-exposure prophylaxis following an injury caused by an NHP. Compared to other individuals exposed to nonhuman primates (NHPs), travelers have two unique characteristics. First, they are typically exposed only once to simian infectious agents, in contrast to the repeated exposure experienced by other at-risk groups. If exposure results in an infection event, travelers may spread these infectious agents to geographic areas where they do not normally circulate. To address the following main objective: to study the prevalence of STLV-1 and SFV infections following a nonhuman primate bite. The study plans to include subjects who have been recently bitten as well as those with a history of nonhuman primate bites. Blood and saliva samples will be collected from the subjects.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Study the prevalence of STLV-1 and SFV infections following an NHP bite. | 17 months | Detection of specific antibodies and viral DNA against both viruses in blood. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Identify risk and demographic factors associated with STLV-1 and SFV infection. | 17 months | The study of associations between STLV-1 and SFV infection and demographic characteristics (age, sex) and those linked to the HNP bite (severity of injury, HNP species) will be analyzed by Fisher's exact test and the Mann-Withney test. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Characterize detected STLV-1 and SFV viral strains | 17 months | Determination of complete viral sequences and integration sites in the human genome. |
| Determine the kinetics of appearance of viral markers (viral DNA and antibodies) for each virus | 17 months | Measurement of viral markers (SFV RNA and DNA, STLV-1 DNA, virus-specific IgM and IgG) in blood and saliva. |
