Epidemiology of

Diagnosed through 2014

Florida Department of Health

HIV/AIDS Section

Division of Disease Control and Health Protection

Annual data as of 12/31/2015

To protect, promote and improve the health of all people in Florida through integrated state, county, and community efforts.

Created: 12/15/15

Revised: 03/31/16

HIV and AIDS Case Data

HIV Infection reporting represents newly Diagnosed HIV cases, regardless of AIDS status at time of report.

HIV infection cases classified as Stage 3 (AIDS) became reportable in Florida in 1981.

HIV infection cases (without an AIDS diagnosis) became reportable in Florida on July 1, 1997.

AIDS cases and HIV infection cases by Year of Diagnosis are NOT mutually exclusive and CANNOT be added together.

Frozen databases of year-end data are generated at the end of each calendar year. These are the same data used for Florida CHARTS and all grant-related data where annual data are included.

HIV prevalence data are prepared later in the year, when most of the “expected” death data are complete, usually in July.

Page 3: Epidemiology of HIV Infection Trends in Florida Diagnosed … · 2020-06-09 · (antibody) HIV tests. Reporting was NOT retroactive. Previously positive tests required re-testing

HIV and AIDS Case Data (con’t)

Adult cases represent ages 13 and older, pediatric cases are those under the age of 13. For data by year, the age is by age of diagnosis. For living data, the age is by current age at the end of the most recent calendar year, regardless of age at diagnosis.

Unless otherwise noted, whites are non-Hispanic and blacks are non-Hispanic.

Total statewide data will include Department of Correction Cases (DOC) unless otherwise noted. County data will exclude DOC cases.

HIV “incidence estimates” are approximations of the numbers of people who are newly infected, which include those whose infection has not yet been diagnosed or Diagnosed.

Surveillance Case Definition

for HIV in Florida

Laboratory Criteria

Positive result on a screening test for HIV antibody, followed by a positive result on a confirmatory test for HIV antibody (e.g., Western blot, IFA, multispot, etc)

ORPositive result or report of a detectable quantity of any of the following HIV virologic (non-antibody) tests:

• HIV nucleic acid (DNA or RNA) detection test (e.g., polymerase chain reaction [PCR]) Has a CD4 of less than 14 percent total lymphocytes

• HIV p24 antigen test, (excluding neutralization assay)

• HIV isolation (viral culture)

HIV Infection Reporting

in Florida

HIV Case Reporting in Florida is based on a positive antibody or antigen test for HIV:

HIV (not AIDS) cases became reportable in Florida on 07/1997, but only via confirmatory Western Blot (antibody) HIV tests. Reporting was NOT retroactive. Previously positive tests required re-testing with a confirmatory test before they could become reportable.

Viral load (antigen) HIV tests became reportable in Florida on 11/20/2006.

As of 2009, all states now have confidential name-

based HIV infection reporting.

Reporting Sources of

HIV and AIDS Cases

Surveillance for HIV/AIDS relies on reporting from the above sources. Additionally, local public health professionals are responsible for case finding and/or epidemiologic follow-up, resulting in a very high completeness of reporting and decent classification of exposure (risk) category.

Note: Enhanced laboratory reporting (ELR) laws in 2006 and the expansion of ELR in 2007 led to an artificial peak in newly Diagnosed cases of AIDS in 2008. This was followed by a general decline in Diagnosed cases through 2012. Another surge in the expansion of ELR in 2012 was followed by another increase in newly Diagnosed cases of AIDS in 2013. AIDS cases in 2014 dropped by 20% from the previous year. Expanded efforts to link people and retain people in care may be a contributor to this decrease. *Source: Population estimates are provided by Florida CHARTS as of 12/16/2015.

the past ten years, the proportion of HIV infection cases among men has increased while the

proportion among women has decreased. The result is an increase in the male-to-female ratio,

from 2.4:1 in 2005 to 3.6:1 in 2014. The relative increase in male HIV cases might be attributed

to proportional increases in HIV transmission among men who have sex with men (MSM).

THE FORMULA USED FOR CALCULATING RATE IS:

– A specific example, using Florida AIDS data:

Number of AIDS Cases Diagnosed in 1996 X 100,000 = 7,300 X 100,000Estimated Population of Florida in 1996 14,000,000

= 52.1 per 100,000 population

(This is the same rate as 5.21 per 10,000 population or 0.521 per 1,000 or0.0521 percent.)

Rates allow direct comparison of the burden of disease on various communities, by taking the population size into account.

RATE = Number of cases in a specified time X 100,000Population at that time

Note: From 2005 to 2014, the proportion of adult HIV cases among whites and blacks decreased

Hispanics (7 percentage points) over this same time period.

Note: Similar to AIDS, black men and to an even greater extent, black women are over-represented in the HIV epidemic. The HIV case rate for 2014 is nearly 6 times higher among black men than the rate among white men. Among black women, the HIV case rate is nearly 14-fold greater than the rate among white women. Hispanic male and female HIV case rate is higher than the rate among their white counterparts. *Source: Population estimates are provided by Florida CHARTS as of 7/9/2015.

Note: HIV cases tend to be younger than AIDS cases. The greatest proportion of HIV infection

cases diagnosed in 2014 were among those aged 20-29 (31%), followed by those aged 30-39

(23%). Conversely, the largest proportion of AIDS cases diagnosed in 2014 was among persons

aged 50 or older (34%), followed by those aged 40-49 (26%).

Over the past ten years, the proportion of newly diagnosed adult HIV cases has shown increases for

both the 20-29 (11 percentage points) and 50+ (3 percentage points) age groups. In contrast, the

proportion of newly diagnosed adult HIV cases among those in the 30-39 and 40-49 age groups

decreased by 5 and 11 percentage points respectively, over the same time period.

Definitions of

Mode of Exposure Categories

• MSM = Men who have sex with men or Male-to-male sexual contact

with person with HIV/AIDS or known HIV risk

• IDU = Injection Drug User

• MSM/IDU = Men who have sex with men or Male-to-male sexual

contact & Injection Drug User

• Heterosexual = Heterosexual contact with person with HIV/AIDS or

known HIV risk

• OTHER = includes hemophilia, transfusion, perinatal, other pediatric

risks and other confirmed risks.

• NIR = Cases Diagnosed with No Identified Risk

• Redistribution of NIRs = This illustrates the effect of statistically

assigning (redistributing) the NIRs to recognized exposure (risk)

categories by applying the proportions of historically reclassified NIRs

to the unresolved NIRs.

Note: For HIV infection and AIDS cases in men diagnosed in 2014, male-to-male sexual contact (MSM) was the

most common risk factor (77% and 65% respectively) followed by cases with a heterosexual risk (18% for HIV

and 25% for AIDS). HIV cases tend to represent a more recent picture of the epidemic.

Impact of STDs

on HIV Infection

• Early detection and treatment of Sexually

Transmitted Diseases (STDs) has a major

impact on sexual transmission of HIV.

• Much of heterosexually transmitted HIV

infections can be prevented by reducing

other underlying STDs.

• STDs increase HIV infectivity and

susceptibility.
