Now here is a worrying development.... as health authorities in Japan think they might have the answer to tracking and blocking the spread of swine flu - keep an eye on the population through mobile phones!
The idea is to track every individual on their phone's global positioning system (GPS).
Then people can be warned if they have crossed paths with anyone diagnosed with a highly contagious illness.
Radio Australia's Connect Asia program reports the scheme is part of an initiative to promote new uses of internet and mobile technology.
It is funded by the Government and will be carried out by Softbank, a big internet and mobile phone provider.
Trials are due to start in a Japanese school in the next few months, but some people are concerned the technology will not be able to keep up with the mass of data to be collected.
