Hi. Just to expand a little on the issue of dengue viruses. As I understand it, four different dengue viruses exist.
I've had dengue twice, each time caused by a different virus and have gained immunity against them. therefore, I can get dengue two more times (2 + 2 = 4) and gain immunity against those types also. But also my chances of escalating to a hemorrhagic dengue stage increases with each event.
I believe most of LM locals have had all four dengue types and they don't fall prey again to those pesky dengue spreading mosquitos like we do.
Now we face the new Chikungunya and we are all equally susceptible, locals and newbies. Cruz
