Chickenpox (
varicella), a viral illness characterised by a very itchy red rash, is one of the most common infectious diseases of childhood.
It is spread by droplets from a sneeze or
cough, or by contact with the clothing, bed linens or oozing blisters of an infected person. The onset of symptoms is 10 to 21 days after exposure. The disease is most contagious a day or two before the rash appears and until the rash is completely dry and scabbed over.
Chickenpox is already contagious one or two days before the typical rash is visible. People usually also have
headaches and joint pain. Chickenpox remains contagious until the final blisters have dried up and the scabs have all fallen off.
It is a little unlikely that you might get infected by the grandson, but i would recommend you to get vaccinated for chickenpox.
Varivax, a two-dose
vaccine for chickenpox, is highly recommended for healthy children, adolescents, and adults who did not have the disease during childhood.Those aged 13 and over who do not have evidence of immunity should get two doses of the vaccine four to eight weeks apart.
