Everything you need to know about the test, its accuracy, and hantavirus infection.
No. The test is a preliminary risk assessment tool and does not replace a clinical examination, laboratory diagnostics, or medical advice. If you have alarming symptoms — high fever, increasing shortness of breath, severe weakness — seek medical help immediately, without waiting for the test result.
The test is based on clinical criteria for hantavirus infection (HPS and HFRS) and epidemiological risk factors. The extended 50‑question version provides a more detailed result. Keep in mind: the accuracy of any questionnaire is limited. Only PCR diagnostics and IgM serology can confirm or rule out hantavirus in a lab.
No. The test runs entirely in your browser. No answers, results, or personal data are sent to the server or saved. Once you close the tab, all data disappears permanently.
Call emergency services immediately (911 or your local emergency number). While waiting: open a window for fresh air, sit in a semi‑reclined position, avoid sudden movements. Tell the dispatcher and arriving medics about possible contact with rodents or visits to rural areas.
Early symptoms are similar: high fever, weakness, muscle pain. Key differences of hantavirus: characteristic exposure history (contact with rodents/dust), rapidly progressing shortness of breath (in HPS) or decreased urine output (in HFRS), a sharp drop in platelet count. The flu does not cause pulmonary edema as fast as hantavirus pulmonary syndrome.
