Study Notes
Incidence and Prevalence
- Incidence measures new cases of a disease or condition over a specific time period
- Prevalence measures existing cases of a disease or condition at a specific point in time
- Incidence is not affected by duration, whereas prevalence is
Study Types
- Case-control study: compares a group with a disease (cases) to a group without the disease (controls)
- Cross-sectional study: examines a population at a single point in time to identify associations between variables
- Cohort study: follows a group of people over time to examine the development of a disease or condition
Screening and Diagnosis
- Specificity of a screening test refers to its ability to detect true negatives (those without the disease)
- Sensitivity of a screening test refers to its ability to detect true positives (those with the disease)
Disease Transmission
- Cyclical transmission: a pathogen requires an alternate host or vector to complete its life cycle
- Cyclo-developmental transmission: a pathogen undergoes developmental changes in a vector or intermediate host
Epidemiology
- Filariasis is an example of cyclo-developmental transmission
- Sample Registration System (SRS) is a dual-record system used to enumerate births and deaths in a population
Demography
- General fertility rate: the number of live births per 1,000 women in the reproductive age group in a year
- India is currently in the second stage of the demographic cycle
Vaccination and Immunization
- Post-exposure prophylaxis (PEP) for meningococcal meningitis involves administration of antibiotics and/or vaccination
- Open vials of IPV and BCG vaccine should not be used
Nutrition
- The recommended daily energy intake for an adult pregnant woman with heavy work is 3050 kcal
Ophthalmology
- Xerophthalmia is a public health problem if the prevalence of night blindness is more than 0.5%
Disaster Management
- Triage involves rapidly classifying injured people based on the likelihood of their survival with prompt medical intervention
