猪流感比季节性流感更具有传染性
在伦敦的研究者近日发表了有关甲型流感的第一份详尽的报告。报告估计猪流感病毒要比普通季节性感冒病毒更具传染性。
Millions of children across Mexico have returned to their classrooms following a nationwide school closure to prevent the spread of swine flu. Many people were still wearing surgical masks as they entered disinfected school buildings. Researchers in London have published the first detailed analysis of the global spread of swine flu. They say initial estimate showed that the virus is much more infectious than seasonal flu. Our science correspondent Pallab Ghosh reports.
通常，季节性流感会传染十分之一的人，而至今为止，猪流感的传染率为三分之一。研究认为，猪流感的致死率约在4‰到14‰之间。
Seasonal flu normally infects one in ten people, so far swine flu has infected a third of the people that have come into contact with the disease. This confirms that millions of people across the world are likely to become infected. The estimate of the proportion of people is likely to kill though is less clear. The study suggests that this might be anything from four in a thousand to fourteen in a thousand. All this confirms what health experts have suspected that we are seeing the early stages of a global pandemic.
