i think its because of the weather recently + world cup fever + lots of late nights + no sleep + late night gathering ( spread the viruses faster as there are gatherings at mamaks for WC games)....these are a FULL PACKAGE to these illness.....80% of my colleague got these symptoms for the past 2 weeks....i guess there are notmuch differences in other places....take more rest and vitamins.....that should boost up our body's immune system...cheers
