Description

Measles, also known as rubeola, is a highly contagious viral infection caused by the measles virus. When the body encounters the measles virus, it produces antibodies, including immunoglobulin G (IgG), as part of the immune response. Measuring measles IgG antibodies in the blood can help determine whether someone has been previously infected with the measles virus or has received the measles vaccine.

A positive IgG antibody test indicates either past infection with the measles virus or immunity due to vaccination. In individuals who have been vaccinated against measles, the presence of IgG antibodies indicates protection against future measles infections. In regions where measles vaccination rates are high, routine screening for measles IgG antibodies can help assess population immunity and guide public health efforts to control outbreaks.
