The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning.
Chickenpox (varicella) is a contagious illness that causes an itchy rash and red spots or blisters (pox) all over the body. Chickenpox can cause problems for pregnant women, newborns, teens and adults, and people who have immune system problems that make it hard for the body to fight infection.
If your child has had the vaccine, this doesn't make you 100% immune to the virus. Know that the Chicken Pox vaccine is only about 80-90% effective, so your child can still have the virus and still be contagious.o overall, the Chicken Pox contagious period lasts anywhere from 2-3 weeks on average, and much longer in cases where there may be a complication. The best thing to do is to keep your child out of school for that period of time and make sure your child is getting proper care.
