ANTC68 Lecture 5: │1
-in the case of health deterioration (living circumstances more stressful, chronic stress on the
body) = impairment on immune system so that mycobacterium gets reactivated (adult-stage
-granuloma: conc. of bacteria in the lungs
-respitory transmission = easy spread and long-term in humans
-TB will destroy bone (goes to area of RBC prod.); partic. spine and spongy parts of bone - in
the spine Pott’s spine (bent spine), in vertebrae (close to the lung) bone
distingrates/collapses/forms wedge
-first migrants to the New World brought TB
*if TB in hard tissue you already have TB thus not latent form (latent = inactivated)
*called consumption b/c consumed from the inside out (no outward symptoms)
Hist. Perspectives on TB?
-Aggressive public health
-overcrowded conditions from indust. and birth of cities TB loves overcrowding
-sanatoriums; instit’s and spas to treat TB
-holistic treatment: needed rest/relaxation/nurses/HC/pleasing environment
*open to poor too; stress levels reduced in these sanatoriums b/c immune syst’s recovered
-then antibiotics created after WW2; drugs created to kill the bacteria rates of TB
plummeted so public health considered it tackled/handled
-post WW2: we can control TB w/ antibiotics, it’s eliminated; huge segments of the world
didn’t have access to these though even in western communities and so TB lived on e.g. Af.
American free slaves and their children, Hispanics, other minorities went underground and not
effecting majority of pop. in control at the time
TB and Minority/Immigrant Groups
-disease of poor/marg./minority - didn’t have the powr to say that they were still suffering from
-CA: poor/marg./immigrants/Ab’s (similar to US)
-rates a/m first nations are still disporp. higher than anyone else
-66% of TB cases are new immigrants/active confirmed diagnosis; 20% are Ab. first nations
-Ab. less than 4% of pop. but make up 20% of all TB cases; more than 5X risk of TB this
hasn’t changed too much, might have came down, but has been disporp. higher since the
advent of antibiotics
-underserved/deprived communities/no water/sanitation/no access to healthcare because
they live in remote areas
-new immigrants 66: imm’s who come to CA have to follow health guidelines (first one is lung
xray in your country before you come here to check for TB) pass it overseas: don’t have active
form (may have latent) but don’t have it coming to CA (immune systems strong at the time) - 3-5
years a good number of them get TB Why? they come here healthy *not getting it in CA but it’s
a case of re-activation of TB: nutrit./health/enviro. stress; lack of fam./friends -psychosoc. stress;
immigrating stress itself; stress of dietary change; stress of unemployment
Epistemology: how we know what we know; factors that influence what we know and
-HIV/ebola ermerg. is going to be based on official health reports e.g. CDC/WHO; global
health org’s
