حمى الوادي المتصدع "Rift Valley Fever" كيف ينتشر الفيروس وكيف تتم الوقاية؟

Quote: Mortality/Morbidity Ebola and Marburg are considered the most severe VHFs, with 25-100% mortality rates. The infection rate is high, particularly for the Zaire subtype of Ebola virus. During pregnancy, Ebola infection has been universally fatal. The South American HF has a case-infection ratio of more than 50% of those exposed. The mortality rate is 15-30%. Lassa fever is a milder infection, with a fatality rate of 2-15%, and is probably much more common than is recognized. Approximately 1% of individuals exposed to RVF virus become infected, but the mortality rate of persons infected is 50%. CCHF has an infection rate of 20-100% and a fatality rate of 15-30%.
