There is major confusion in this country between varicela and vireula (spelling might be off on these, sorry). Many times, varicela (chickenpox) is referred to as vireula (smallpox) here in the DR. I am not sure why, perhaps the similarity in spelling, pronunciation and/or general confusion.
The chickenpox make their way around the city of Santiago every spring, slowly spreading their way through the schools and taking a lot of kids out during final exam week, great timing! Typically the bumps appear first on the stomach or back, then begin to spread over the body. If caught early, you can get a pill (do not know the name) from your doctor to lessen the severity of the illness. An adult friend of mine recently did this and ended up with only abour 15 spots, in total. Since varicela is a form of herpes zoster, the virus lays dormant in your body for up to 2 weeks before the spots become visible. Those infected are contagious during this two-week period as well as 10-14 days after the spots come out. Most doctors will tell you to lay low at home for 2 weeks, in order to avoid spreading this itchy little beast.
If a young one contracts it, put socks on their hands to prevent major itching and scarring as well as infection, strip them down to their undies to avoid irritation caused by clothing, and stick them in front of a fan (feels good!). Taking baths with oatmeal and baking soda can be helpful as well as applying calamine and or a paste made from baking soda and water. Anti-allergy pills are good for the itching and even little ones can take low doses of benadryl. Tylenol is good for the occasional fevers that it brings. Other than that, rest, relaxation, and lots of fluids are helpful as well. Sulphuric soap is good to use on the scars once the virus is gone, although beware of the stinky smell!
The vaccine does not prevent the virus, it only lessens the severity. There is no reason to keep your kids away from the virus, as most are bound to get it at some point and it is better to have it at a younger age when it is deemed less risky.
As for the Vicks, if it isnt hurting anybody, let them rub it all over the place. This is all mind over matter and in the end, does it really matter....? At least their sinuses will be clear!
