It doesn't matter if it's acknowledged as a health risk or not. They're doing their best to find out what it is- bacterial or viral.
Beyond that, there is no remedy... well, unless you wanna start injecting bleach in your veins.
Seriously though, either your immune system is up to snuff and you can fight this-- or you can't.
Take a lot of vitamin C & Zinc, drink a lot of liquids, eat chicken soup, wait 2 weeks.
If you are REALLY worried, don't take cold/flu medicine or drink alchohol as they both will slow your body down and make it more difficult to fight the infection. Just drink chamomile tea (hey, it works) for your aches and sore throat.
Now if a new form of the bubonic plague comes around, or HIV/AIDs becomes airborne, THEN we got problems.
