MSRA is a different animal, altogether. And the fact that we are dealing with it here should be an indication that it was born here.
Hydrogen Peroxide is the best killer of MRSA that I know of.
FYI, I don’t think there are any vaccines for dengue fever. It is carried by a mosquito, which has to bite a sufferer and then quickly bite a healthy person, a lot like malaria. But with dengue, a sufferer must treat the symptoms and hope for the best as the disease “runs its course.” Good food, clean water and plenty of rest are the best ways to treat dengue. And if you do happen to develop dengue, as my husband did, be prepared for extreme depression to set in. It takes around 6 months for all of the symptoms to disappear.
