There is a context for fear of infectious diseases, and history can inform. I found this quote by Helen Keller’s grand-niece:
"In the 1800s…Helen's illness was diagnosed by her doctor as "acute congestion of the stomach and the brain" or "Brain Fever," as it was sometimes called. Doctors today feel that it was most likely a case of scarlet fever or meningitis. Another possibility is a virulent strain of rubella, since Alabama was experiencing an epidemic around the time of Helen Keller's illness."
~ Keller Johnson-Thompson, Helen Keller's great-grandniece
Being vaccine free and knowing about rubella and how homeopathy can help is essential.
