The risk of transmission to non-immune individuals can be as high as 90% following close contact [10]. Therefore, when a case of varicella occurs in an environment with many young children, the risk of transmission is an important concern for parents.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt; color: #000000;\">Varicella vaccination schedule consists of 2 doses:<\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt; color: #000000;\">Dose 1: from 12 months old<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt; color: #000000;\">Dose 2: 3 months after dose 1 (at least 4 weeks apart) [9]<\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt; color: #000000;\">The best way to prevent varicella is through vaccination.
