If someone has been exposed to measles , how does public health determine if they are immune ? A blood test is the most reliable method. Wrong frame with this question. The claim is more that the people who can not be vaccinated ( immune system issues, too young etc) are at risk.

I am vaccinated and run no risk from an unvaccinated person. People who have been appropriately vaccinated (or who have had the disease) and who are exposed to a patient with measles do not need to do anything. If an unimmunized person is exposed to a patient with measles , they should receive the vaccine as soon as possible. This may prevent the disease if given within hours of exposure.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. During a measles infection, a person has fewer protective white blood cells. It is possible to catch measles simply by being in a room where another person who has the disease has been.

People who have measles are infectious from about days after they have been exposed to the virus until days after the rash appears. Other people who are considered immune by the CDC include those who had a laboratory-confirmed case of the measles , those who had a lab test that confirmed they were immune and those born before.

For people having had measles , it is rare to ever have a symptomatic reinfection.

The measles virus can kill cells that make antibodies, and thus permanently weaken the immune system. The trademark symptom is a blotchy, red rash. The silenced dendritic cells and macrophages, do what they always do when there is an invading pathogen: they travel to nearby (or draining) lymph nodes.

Once there they pass the measles virus to other immune cells, cell-to-cell.
