Notable Diseases
AP Environmental Science
Slide2Malaria
Pathogen and/or VectorProtozoa carried by mosquitosHealth ImpactsFever, chills. Kills millions each yearOther important informationMedicine will cure, but hard to get in Africa. Mosquito nets prevent infection. DDT also prevents.
Slide3West Nile Virus
Pathogen and/or VectorVirus carried by mosquitosHealth ImpactsFever, chills. Can be deadlyOther important informationDead birds are 1st indicators of disease. “Newer” disease in USA
Slide4Cholera
Pathogen and/or VectorBacteria in waterHealth ImpactsDiarrhea and deathOther important informationEliminated in USA, but still in developing countries without clean water to drink
Slide5Giardia
Pathogen and/or VectorProtozoa in waterHealth ImpactsDiarrhea and sometimes deathOther important informationIn rivers and streams in USA. Hikers/backpackers need to filter water
Slide6Tuberculosis
Pathogen and/or VectorBacteria in airborne droplets (coughs/sneezes)Health ImpactsCough (possibly with blood), chest painOther important informationPartially preventable by vaccine
Slide7HIV/AIDS
Pathogen and/or VectorVirus in blood and bodily fluidHealth ImpactsAttacks the immune system. DeadlyOther important informationWorldwide, but epidemic in Africa
Slide8Food-borne illness
Pathogen and/or VectorE. Coli and Salmonella are two kinds (bacteria)Health ImpactsVomiting, diarrhea, occassional deathOther important informationAffects 48 million each year in USIncreasing due to industrialized agriculture
Slide9Yellow Fever
Pathogen and/or VectorVirus carried by mosquitosHealth ImpactsFever, chills, and death. Damages liver (turns people “yellow”)Other important information“older disease” used to kill lots of people in tropical countries
Slide10Cryptosporidium
Pathogen and/or VectorBacteria with hard capsule or shellHealth ImpactsDiarrhea and deathOther important informationCannot be killed by chlorine. Needs to be “zapped” with ozone or UV. Killed 69 people in Milwaukee in 1993 with 400,000 sick.
Slide11Hepatitis A,B,C
Pathogen and/or VectorVirus in blood and fecesHealth ImpactsJaundice –liver damage. Possible deathOther important informationVaccines available
Slide12Influenza
Pathogen and/or VectorVirusHealth ImpactsFever, chills. Kills thousands in USA each year (usually elderly)Other important informationH1N1 (swine flu) tends to infect young people
Slide13Pertussis (Whooping Cough)
Pathogen and/or VectorBacteria—highly contagiousHealth ImpactsUncontrollable, violent coughing, inability to breath.Other important informationVaccines highly effective to prevent, but has resurgenced due to non-vaxxers.
Slide14Measles
Pathogen and/or VectorVirus—highly contagiousHealth ImpactsSevere respiratory disease with entire body rashOther important informationSame as pertussis
Slide15Schistosomiasis
Pathogen and/or VectorParasitic Worms carried by freshwater snails, spread through contaminated waterHealth ImpactsA rash, itchy skin, fever, chills, cough, headache, belly pain, joint pain, and muscle achesOther important informationTreatable with medication
Slide16Urban Ecology has lead to higher disease risk
Use Services
Day Care, cleaning services, food prep service, spa and
beauty
Restaurants and pre-made food
Increased dramatically. Levels of food-borne illness have skyrocketed despite better refrigeration and food preservation.
Slide17Urban Ecology has lead to higher disease risk
Beauty parlor/Barbershops have increased services
Each extra service (waxing,
mani
/
pedi
, facial etc.) adds to additional reservoirs of pathogens, vectors and transmission risk
.
Health clubs and gyms
Mycobacterium is found in indoor pools and hot tubs.
Many pathogens are now chlorine-resistant.
Slide18Urban Ecology has lead to higher disease risk
Globalization
Allows pathogens to “hitchhike” their way to new hosts in new parts of the world
More urban dwellers
Any concentration of people will increase the risk of disease transmission.
Floods, El Nino, hurricanes, earthquakes (Haiti for example) in cities bring high risk of disease
