incidence

Epidemiology 
1. The number of new cases–in the form of a count or rate of a disease or condition, often an infection diagnosed each yr–classically measured as an attack rate.
2. The rate of occurrence of new cases of a disease or condition in a population at risk during a given period of time, usually 1 yr.

2. optics Intersection of a ray of light with a surface.

incidence

The number of cases of an event, such as a disease, occurring in a particular population during a given period. Incidence is usually expressed as so many cases per 1000, or per 100,000, per year. Compare PREVALENCE.

incidence

1. The intersection of a ray of light with an optical surface. 2. The number of new cases of a specific disease or condition occurring during a specific period of time (e.g. 1 year) divided by the population at risk during that period. Example: the incidence of keratoconus in Olmsted County, Minnesota was found to be 2 cases per 100 000 population a year. See prevalence.

Patient discussion about incidence

Q. Is it possible to get ADHD from suffering a traumatizing incident? lately, after the death of my Grandmother. I have been increasingly getting the symptoms of ADHD. I have suffered from some of the symptoms during my childhood, but now they are increasingly occurring. And I am finding it really hard to listen to Teachers, follow instructions and do coursework. Is it possible this was caused by the death of my grandmother?

A. I think you should look up depression. ADHD is something that does not “pop”, more reasonable to think is that you suffer from a slight depression. Check it out and see if it fits :

Q. Is the incidence of breast cancer growing everyday? I have a small lump in my breast. My friends suggested me to have a regular mammogram as a precautionary step. My friend’s family women are having it yearly. But I am confused…Why is the need to go for mammogram without any problem. I think routine medical check-up is sufficient. Is the incidence of breast cancer growing everyday?

A. NO….its not increasing. I had my breast cancer found in early stages, 6 month back. I was lucky. You know why—I had my mammogram done just by fear of having it in future. In order to avoid any I did and was very lucky as it was found and soon cured. Most female take it as precaution and you should too. Apart from mammogram you must have clinical breast examination.

Various extrinsic factors such as air pollution,10 gastrointestinal infection11 and low fiber diet during summer months could contribute to the higher incidence of appendicitis.11 Although numerous epidemiological studies on appendicitis have been conducted, most have focused on Western populations,12 relatively few epidemiological studies have focused on appendicitis in Asian populations.
Overall, the incidence rose 25% in men from 1998-2002 to 2008-2012 (an average annual age-adjusted incidence of 34.7 to 43.5 per 100,000 person-years), and by 21% in women between those two time periods (from 21.7 to 26.2 per 100,000).
The ABCs program defined a confirmed case of legionellosis as "the isolation of Legionella from respiratory culture, detection of Legionella antigen in urine, or seroconversion (a more than fourfold rise in antibody titer between acute and convalescent sera) to Lp1." Unlike NNDSS, the ABCs program recorded clinical and race data for each patient found to have legionellosis; incidence rates among blacks were found to be higher than among whites per 100,000 individuals: 1.0 vs.
To assess the impact of the disease-free interval on the incidence estimation, we widened the interval previous to the quarter of prevalence (2008/I) by consecutively adding a quarter of the year, that is, one quarter disease-free interval, two quarters, three quarters, 1 year, 1 year and one quarter, etc.
In this study, our primary objective was to evaluate the impact of interventions on reducing the incidence of colonization with or infection caused by antimicrobial drug-resistant pathogens or CDAD.
