Measles on the Faroe Islands 1846 • No measles in 65 years on the Faroes • Panum dispatched to study the epidemic and provide medical support by the Danish government as a medical student • 6000 of 7782 residents affected – in some communities 19/20 were affected • Observations were made on the people, and village to village spread involving 52 communities (Each settlement was an isolated community in which the disease could be studied) • His thesis is the first and most complete description of a disease in the history of epidemiology ; he writes the classic ‘Observations Made During the Epidemic of Measles on the Faroe Islands in the year 1846’ published in 1847
Measles in the Faroe Islands(1846) • ‘the circumstances under which the disease was observed were so favourable that similar ones were rarely, if ever, presented to an observer.’ • No miasmatic origin – it spread man to man! • Incubation period was 13-14 days • Begins in a community when the primary case is in the eruptive stage • Could not fined a single case traceable to exposure after the disappearance of the rash
Measles on the Faroe Islands(1846) • Describes the lasting immunity – 98 ‘old persons’ escaped the disease • Has difficulty excluding the part fomites play in transmission of the disease • Not a Zoonotic disease • Thought it spread thru the ‘gaseous emanations’ of the human

McLennan County Medical Community(1982) • There was no Hepatitis B in Waco, Texas (but the hospitals did not test for it) • One hospital had no microbiologist and no instrumentation; the other hospital had an infection control committee run by a medical technologist; ‘quality assurance’ was just beginning to get started • The chief pathologist at one hospital couldn’t spell or pronounce ‘Chlamydia’; the pathologist at the other hospital admitted he knew nothing about microbiology and wasn’t interested in modernizing as long as the other hospital had facilities for ‘those kind of problems’ • Town had many ‘family doctors’ and ‘GP’s’ who were World War II veterans with only GI, Cardiology and Nephrology represented as medical specialties: One hospital did all of the medical specialty procedures (endoscopy, dialysis, and catheterizations) and the other hospital did OB/GYN, and surgical procedures. Most of the physicians thought they knew everything, and all of the older physicians new very little about teamwork. • ‘If you have a “sick patient, you need to get them out of town!’ – Dallas or Houston, not Temple! • ‘Good Old Boys’ network and it extended into the other areas of the community – like the business community and legal community and the clergy!
McLennan County Medical Community(1982) • Baylor University pushes the community to modernize itself – student pressure, academic freedom and discourse, and Turnover • Hospitals were having to compete with Scott and White, …………30 miles south! • Media was becoming more aware of ‘medical stories’; No computers, internet., media, or cell phones • Business was just becoming aware of the medical community as an economic force • Influx of young medical and surgical specialists • Hospital administrators and Community leadership was sincerely committed to improving the community on all levels.

Waco-McLennan County Health District • County has a mandate to put aside a certain amount of it’s budget for health care (10%) • City and county came together and the city funds the health department while the county funds indigent care • Department has a good ‘feel’ for the community because everyone knows one another
