The former head Microsoft, Bill Gates, has warned that the world could be great danger bio-terrorism. He said the world could face a catastrophe a virus made terrorists that could kill 30 million people less than a year. Mr Gates, the richest person the world, was speaking the Munich Security Conference in Germany. He said there was a "reasonable" chance that a bio-terrorist could act the next 10 to 15 years. He added that world leaders are not prepared such an attack. He expressed his surprise that very few leaders were even aware it. He asked for global "health security" to become a major part government discussions and policies.

Mr Gates explained that: "The next epidemic has a good chance originating a computer screen." He said a genetically engineered virus was easier to make and could kill more people than nuclear weapons, but no country Earth is ready this threat. He asked governments, "to prepare these epidemics the same way we prepare for war". Gates asked governments to start "germ games" activities to prepare a bio-terrorist attack, like many countries engage war games. He said we needed better monitoring to spot outbreaks early, and systems to quickly develop vaccines - weeks rather than years. "We need a new arsenal weapons, anti-viral drugs, antibodies, vaccines and new diagnostics," he said.
