Maybe Earl should have added "Get chickenpox vaccine" to his infamous list. Actor Jason Lee, star of the TV comedy "My Name is Earl" is reportedly ill with chickenpox. While Lee's performance as a reformed jerk is hilarious, getting the viral infection known as varicella as an adult is no laughing matter. While kids suffer high fevers, extensive itchy blisters and the potential for permanent pock marks, grown-ups can have an even rockier ride. Viral pneumonia and encephalitis (brain infection) make rapid treatment paramount. We are not aware of the details in Lee's case, but production of the show has been shut down until he recovers. Antiviral pills like Valtrex can stop the virus in its tracks, allowing folks like Earl to get back to charitable deeds. Anyone unsure if they had the childhood rash can get a blood test to see if they are immune. If not, the varicella vaccine can safely prevent this happening to others. Once again, with his example, "Earl" can help humanity.
