There was a world-wide scare when avian flu broke out in Asia last year. In Kenya, where I reside, there has been a recent outbreak of Rift-valley fever, which has killed almost 150 people in less than four months. This is more than Avian flu has killed so far. While avian flu affects mostly birds, Rift valley fever affects animals like cows, goats etc.. Both are viral, and both at times infect humans. In either case, human fatalities on infection is not a must. Why isn't there a similar concern with Rift valley fever as there was with avian flu? Is one less virulent, or less dangerous than the other? What makes avian flu more dangerous?
