Hantaviruses, RNA viruses from rodents, cause severe diseases like Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS). Early ribavirin may aid treatment for these significant public health threats.

Area of Science:

  • Virology
  • Infectious Diseases
  • Public Health

Background:

  • Hantaviruses are enveloped RNA viruses in the Bunyaviridae family, transmitted by rodents.
  • Infection in rodents is asymptomatic and lifelong, with no known human-to-human transmission.
  • Two main disease forms exist: Hemorrhagic Fever with Renal Syndrome (HFRS) and Hantavirus Pulmonary Syndrome (HPS).

Purpose of the Study:

  • To summarize the characteristics of hantaviruses and the diseases they cause.
  • To differentiate between HFRS and HPS presentations and associated viruses.
  • To outline current management strategies for hantavirus infections.

Main Methods:

  • Literature review and synthesis of existing data on hantaviruses.
  • Classification of hantaviruses based on geographic distribution and disease presentation.

  • Description of clinical manifestations and treatment approaches.
  • Main Results:

    • HFRS is caused by Hantaan, Seoul, Puumala, Porogia, and Belgrade viruses, with varying severity and geographic prevalence.
    • HPS, caused by Muerto Canyon Virus, is a severe respiratory illness with high mortality.
    • Hantaan virus is common in the Far East, Puumala in Western Europe, Porogia/Belgrade in the Balkans, and Seoul globally.

    Conclusions:

    • Hantavirus infections present as HFRS or HPS, requiring distinct management strategies.
    • Geographic location and specific virus strain influence disease presentation and severity.
    • Supportive care, including dialysis, and potentially early ribavirin are key to managing hantavirus infections.
