Detailed explanation-1: -Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). The virus spreads easily from people with chickenpox to others who have never had the disease or never been vaccinated.
Detailed explanation-2: -These red spots-which are about 1/5 inch to 2/5 inch (5mm to 10mm) wide-were once thought to look like chickpeas (garbanzo beans). Another theory is that the rash of chickenpox looks like the peck marks caused by a chicken. But, in case you were wondering, chickenpox can’t be caught from a chicken!
Detailed explanation-3: -Measles is an acute viral respiratory illness. It is characterized by a prodrome of fever (as high as 105°F) and malaise, cough, coryza, and conjunctivitis-the three “C”s-, a pathognomonic enanthema (Koplik spots) followed by a maculopapular rash.
Detailed explanation-4: -Varicella (chickenpox) is an acute infectious disease. It is caused by varicella-zoster virus (VZV), which is a DNA virus that is a member of the herpesvirus group. After the primary infection, VZV stays in the body (in the sensory nerve ganglia) as a latent infection. Primary infection with VZV causes varicella.
