Hantavirus Hemorrhagic Fever with Renal Syndrome
Hantavirus Hemorrhagic Fever with Renal Syndrome (HFRS) is a severe, acute viral disease caused by Hantavirus species that are mainly transmitted by rodents. Pronounced as Han-ta-vi-rus Hem-o-rrhag-ic Fe-ver with Re-nal Syn-drome, the term Hantavirus is derived from the Hantan River in South Korea, where the virus was first isolated.
Symptoms
The symptoms of HFRS can be divided into five phases: febrile, hypotensive, oliguric, diuretic, and convalescent. The febrile phase is characterized by sudden onset of fever, chills, headache, backache, abdominal pain, and nausea. The hypotensive phase may lead to shock. The oliguric phase is characterized by kidney failure, while the diuretic phase involves excessive urination. The convalescent phase is the recovery period.
Transmission
HFRS is primarily transmitted to humans through direct contact with rodent urine, droppings, or saliva of infected rodents. It can also be transmitted through inhalation of aerosols and possibly by ingestion of contaminated food or water.
Treatment
There is no specific treatment for HFRS. However, early recognition and hospitalization can greatly improve a patient's prognosis. Supportive therapy, including rehydration and correction of electrolyte imbalances, is important.
Prevention
Prevention of HFRS primarily involves avoiding contact with rodents and taking precautions when handling rodents or cleaning areas where rodents have been present.
