Shocking!!

Measles is suspected to be associated with a form of immunity amnesia. Having had the disease can cause a patient’s immune response to other diseases to fall short.

“The measles virus can deplete previously acquired immune memory by killing cells that make antibodies, and thus weakens the immune system, which can cause deaths from other diseases. Suppression of the immune system by measles lasts about two years and has been epidemiologically implicated in up to 90% of childhood deaths in third world countries, and historically may have caused rather more deaths in the United States, the UK and Denmark than were directly caused by measles. Although the measles vaccine contains an attenuated strain, it does not deplete immune memory.”

Also, measles is one of the most contagious diseases known for a variety of reasons.

He was 10 years old. First he had Measles in late spring. Then when he was OVER the Measles, his weakened immune system allowed a fatal pneumonia in June.

That was a common pattern in those days before safe and effective vaccines.

George Washington was sterile. Never had children of his own. Measles when he was 19. Measles can make males sterile.

Today the South Carolina Department of Public Health (DPH) said the state’s outbreak total is now 876, after adding 29 more cases since January 30 in an outbreak report.

“DPH has also confirmed a case of measles in a Sumter County resident. At this point in the investigation, it is not yet clear whether this new case is linked to the Upstate outbreak centered around Spartanburg County or if the case may have been exposed where measles is occurring in other locations,” DPH said in its report.

Most of the new cases are close case contacts, but multiple sites of possible public exposure are listed on the DPH website, including restaurants and grocery stores in Sumter County.

There are currently 354 people in quarantine and 22 in isolation in South Carolina. Among confirmed cases, 800 case-patients are unvaccinated against measles. Only 22 are fully vaccinated, and 16 are partially vaccinated against the virus. Vaccination status is unknown for 38 patients. Almost two-thirds of cases (555) have occurred in patients ages 5 to 17, 233 cases are in children under the age of 5 years, 71 cases are in those 18 or older, and 17 have unknown age.
