Slide 3

Public Health Is the science and craft of averting malady, delaying life, and advancing wellbeing through the composed endeavors of society including Monitoring illness and other wellbeing related conditions (observation); and Identifying and measuring imperative patterns (the study of disease transmission).

Slide 4

Surveillance Is the observing of the event of a sickness or other wellbeing related condition. Dynamic reconnaissance Actively scanning for individuals with an ailment or condition. Latent observation Dependent on reporting from outer sources.

Slide 5

Epidemiology The investigation of the conveyance, determinants, and hindrances of sickness or other wellbeing related conditions. Dispersion is the recurrence and examples as far as individual, place, and time (who, where, and when). Determinants are components that cause or add to a sickness or condition. Impediments are variables that avoid or diminish the shot of building up a sickness or condition.

Slide 6

Prevalence = Number of individuals influenced ______________________________________ add up to populace Prevalence The extent of a populace that has a sickness or wellbeing related condition amid a particular time.

Slide 7

Case Study February 2004. School nurture reported 39 instances of this season's cold virus in the secondary school. Period of understudies 14–18 years Total of 780 understudies in the school. What was the pervasiveness of seasonal influenza for this secondary school?

Slide 8

Prevalence = Number of individuals influenced ______________________ add up to populace Prevalence = 39 understudies with influenza _____________________ 780 aggregate understudies Prevalence = 5 out of each 100 understudies had this season's flu virus. Can likewise be said 5% of understudies had this season's flu virus. Pervasiveness Calculation Report who, where, and when. Populace: Students matured 14–18 Place: High educational Time: February 2004

Slide 9

Case Study — Continued Results 5 out of 100 understudies had this season's cold virus. Screen the circumstance amid the month of March (2004). 9 new instances of influenza inside the school. Figure the frequency amid this day and age.

Slide 10

Incidence The rate at which new illness or wellbeing related condition happens in a populace. Frequency = Number of recently influenced individuals ___________________________________ populace at hazard Incidence = 9 new instances of influenza ___________________ (780 – 39) populace at hazard Incidence = 12 out of 1,000 understudies had this season's cold virus at the secondary school

Slide 11

Case — Study Continued Results — 12 out of 1,000 understudies had this season's flu virus. What is the cause? An educator specified seeing understudies hacking and wheezing around the confection machine. The attendant researched to check whether there was any connection between's the confection machine and having this season's cold virus.

Slide 12

Case Study — Continued The attendant observed 200 understudies over a 1-month time frame. 120 utilized the treat machine. 12 instances of influenza happened in this gathering. 5 instances of influenza showed up in the gathering that didn't utilize the sweet machine. So was there a hazard in utilizing the confection machine?

Slide 13

Prevalence Ratio of predominance of sickness in the uncovered gathering isolated by the pervasiveness of malady in the unexposed bunch.

Slide 14

Prevalence Ratio = A/(A+B) _______ C/(C+D) Prevalence Ratio 2 2 Table

Slide 15

Prevalence Ratio = 12/(120) = 1.6 _______ 5/(80) Prevalence Ratio 2 2 Table

Slide 16

Analysis of Prevalence Ratio If esteem >1, then introduction is creating result. On the off chance that esteem =1, no association amongst introduction and result. In the event that esteem <1, introduction is restricting the result. For the situation ponder, the pervasiveness proportion was 1.6. Hence, understudies utilizing the confection machine were 1.6 times as prone to get this season's cold virus as understudies not utilizing the sweet machine.

Slide 17

Prevention The last stride of general wellbeing is counteractive action. In the event that you were the school nurture, what avoidance program would you produce for your school?

Slide 18

Summary Pubic wellbeing is the science and craft of forestalling malady, dragging out life, and advancing wellbeing through the composed endeavors of society. There are three sections to general wellbeing: Surveillance , which screens sicknesses and wellbeing related conditions. The study of disease transmission , which distinguishes and measures patterns (pervasiveness, occurrence, and hazard proportion). Counteractive action , which incorporates programs that advise and teach the populace at hazard.
