Thread🧵on modes of pathogen transmission. #monkeypox
Transmission is messy, and there is no single mode that pathogens employ to invade a body. Indeed, modes can change.
Plague provides a great example of this: it occurs in multiple forms, depending on transmission route. 1/13
All are caused by the bacterium Yersenia pestis
Bubonic plague occurs when infected fleas bite a person, or the bacteria enter through a break in the skin. Infection causes characteristic "buboes"
Preventative strategy would be flea and rat control. 2/13 https://t.co/xR5gdRuK53
Plague can become more widespread via the bloodstream, causing septicemic plague. This leads to black areas of necrosis in the body, hence the term, "Black Death."
As long as it doesn't get to the lungs, prevention is the same as previous - flea and rodent control. 3/13
However if the bacteria set up infection in the lungs, they can now exit the body via respiratory aerosols
This is now pneumonic plague, a highly contagious form of the disease, transmissible by air, with an incubation period of only 1-3 days & 100% fatal without treatment. 4/13
The infection control measures of flea and rodent control are ineffective against pneumonic plague -- isolation and treatment of cases, airborne precautions, and prophylactic treatment and monitoring of exposed individuals are needed. 5/13

Great article from @AsheSchow. I lived thru the 'Satanic Panic' of the 1980's/early 1990's asking myself "Has eveyrbody lost their GODDAMN MINDS?!"
The 3 big things that made the 1980's/early 1990's surreal for me.
1) Satanic Panic - satanism in the day cares ahhhh!
2) "Repressed memory" syndrome
3) Facilitated Communication [FC]
All 3 led to massive abuse.
"Therapists" -and I use the term to describe these quacks loosely - would hypnotize people & convince they they were 'reliving' past memories of Mom & Dad killing babies in Satanic rituals in the basement while they were growing up.
Other 'therapists' would badger kids until they invented stories about watching alligators eat babies dropped into a lake from a hot air balloon. Kids would deny anything happened for hours until the therapist 'broke through' and 'found' the 'truth'.
FC was a movement that started with the claim severely handicapped individuals were able to 'type' legible sentences & communicate if a 'helper' guided their hands over a keyboard.
For three years I have wanted to write an article on moral panics. I have collected anecdotes and similarities between today\u2019s moral panic and those of the past - particularly the Satanic Panic of the 80s.
