Basic Concepts of Epidemiology
Starting from slide 32
What are healthcare-associated
infections?
● They are acquired while receiving
treatment in a health-care facility
● Known as nosocomial infections
○ 1 in 25 ppl affected
How do you get HAIs?
1. Microorganisms in environment
2. Weakened state of host
Comprised host: individual
who is not resistant to
infection b/c of disease,
therapy, burns etc.
     3. Chain of transmission in hospital
What are emerging infectious diseases?
● New, increasing in incidence,
show a potential increase in near
future, or re-emerging.
● Most zoonotic, viral, and likely
vector-born (transmitted by
insect/tick bite)
What are contributing factors in emerging
diseases?
● Genetic recombination  avian flu
● Evolution of new strain  V.
cholerae
● Use of antibiotics/ pesticides
leads to antibiotic resistant strains
● Changes in weather→ Hantavirus:
associated w/ rodents in the States
● Modern transportation→  West Nile
Virus in NY
● Ecological disasters, war,
development
Coccidioidomycosis (fungal
infection) due to Earthquakes
● Animals Lyme Disease
● Public Health Failure Diphtheria
Important people in Epidemiology
● John Snow (1848-1849)
identified reservoir of cholera in
London
● Ignaz Semmelweis (1846-1848)

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
