Symptomatic and travel to New World Arenavirus endemic areas or contact to travellers from these areas.

Completed Special Pathogens requisition including sender name, address and telephone number. Patient information including name or identifier, date of birth, and all relevant patient history including clinical diagnosis, underlying diseases, exposure risk and travel history. Indicate type of specimen collected and all specimen information. Select all required tests. If possible, attach lab results that have already been done at local or provincial laboratories.

All patient history must be included; sample without adequate patient history to justify testing are subject to rejection. Contact Special Pathogens prior to submission of sample to ensure appropriate shipping documentation is generated.

For diagnosis of New World Arenavirus infection to be confirmed, one or more of the following diagnostic markers must be positive: (i) presence of antibodies to New World Arenaviruses, (ii) presence of New World Arenavirus RNA by RT-PCR, and (iii) isolation of New World Arenavirus. Turnaround
