    Dee, a full answer to your 3-part question would take a few books. Let me use one disease with all 3 connections. Consider rubella, a disease caused by a virus. It is most serious in pregnant females because it can harm their unborn baby. It is also called German measles or 3-day measles.

    Rubella can affect anyone who has not had the disease or who has not been immunized against it.

    Rubella is spread through the air by coughing, sneezing or talking.

    In children the disease usually begins with a rash. The rash appears on the face and neck. The rash lasts about 2 or 3 days. In older children and adults there may be a low-grade fever, swollen glands in the back of the neck and an upper respiratory infection (URI) before the rash begins.

    A doctor can confirm that an illness is rubella through a blood test.

    What are the complications associated with rubella? For most children and adults rubella is relatively mild. However, if a women is in her 1st trimester of pregnancy catches the disease her baby has up to a 90% chance of being born deaf, blind, mentally retarded, with heart defects or stillborn. These conditions are referred to as Congenital Rubella Syndrome (CRS).

    Is there a treatment for rubella?

    There is no specific treatment for rubella.

    Can rubella be prevented?

    Yes. Rubella vaccine given in combination with Measles and Mumps (called MMR vaccine) is recommended for all children at 12-15 months of age and at 4-6 years of age. The two doses of vaccine normally provide life long immunity.

    Does a past infection with rubella make a person immune for life? Yes

    I hope this info will be of help.

    ordinary. An expression does not have an answer and an equation does. Expression- 9+A Equation- 9+A=10 No, you are able to't remedy a variable in an expression, because of the fact there is not any answer to an expression! definite, you are able to remedy for a variable in an equation, because of the fact it has a answer!
