Vectorborne and soilborne bacterial and viral diseases - Hantavirus and Hantavirus Syndromes
3 important questions on Vectorborne and soilborne bacterial and viral diseases - Hantavirus and Hantavirus Syndromes
What are the key characteristics of HPS and HFRS caused by hantaviruses?
HPS involves acute respiratory and cardiac symptoms with high mortality. HFRS exhibits renal dysfunction, hemorrhagic complications, and is prevalent in Eurasia.
Describe the transmission of hantaviruses from rodents to humans. What are the symptoms of HPS, and how does it differ from HFRS?
Hantaviruses are transmitted by inhaling virus-contaminated rodent excreta. HPS symptoms include fever, nausea, muscle pain, hemorrhaging, with a high mortality rate. HFRS presents with headache, pain, renal dysfunction, prevalent in Eurasia.
Explain the handling precautions for hantaviruses in laboratories. Why are hantaviruses considered "the worst of the worst" in infectious diseases?
Hantaviruses require Biosafety Level 4 (BSL-4) precautions. They are considered "the worst of the worst" due to the associated danger, alongside Ebola and other BSL-4 pathogens.
