First, you can make sure you are up to date on all vaccine-preventable diseases like measles, mumps, rubella, and varicella .
Making a clinical diagnosis, and, in particular, differentiating smallpox from varicella , is difficult even when those concerned are seeing both diseases regularly.
Unlike varicella , herpes zoster is a sporadic disease with an estimated lifetime incidence of 10 to 20 percent.
The varicella virus is communicated easily through saliva.
Alternatively, the faculty might have contagious diseases, such as tuberculosis or varicella , and could infect patients.
Pneumonia is a known complication of rubeola, varicella , and pertussis.
Although a small percentage of vaccinated children contract varicella each year, these illnesses are much less severe than those occurring in unvaccinated children or adults.
For example chickenpox and shingles are both caused by the same herpes virus - varicella zoster virus.
Chickenpox is caused by the varicella zoster virus, and the main symptoms are a high fever and itchy red spots that blister and develop a crust.
Later the virus, now known as the varicella zoster virus, was identified and isolated, and the researcher responsible received a Nobel prize.
