[The epidemiological surveillance of AIDS in Panama]
Insights
Epidemiological surveillance of Acquired Immunodeficiency Syndrome (AIDS) in Panama reveals shifts in transmission. Heterosexual contact increasingly drives new infections, particularly among women and men aged 20-40.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Context:
- AIDS surveillance in Panama provides insights into disease patterns.
- Demographic and transmission trends are crucial for public health interventions.
Purpose:
- To analyze the epidemiological surveillance of AIDS in Panama.
- To detail incidence by sex, residence, transmission mode, and mortality.
- To identify changes in AIDS epidemiology over time.
Summary:
- AIDS incidence in Panama shows sex-specific patterns: girls <4 years affected more, while boys and men are predominantly affected in other age groups.
- Since 1991, a notable increase in affected women and men occurred, with a shift from homosexual to heterosexual transmission.
- Most patients (20-40 years) likely contracted HIV during adolescence, with sexual exposure as the primary transmission route, followed by blood products and perinatal exposure.
Impact:
- Highlights the changing dynamics of the AIDS epidemic in Panama.
- Informs targeted prevention and treatment strategies based on demographic and transmission shifts.
- Underscores the importance of adolescent sexual health education in combating HIV/AIDS.
Abstract:
The authors report the results of the epidemiological surveillance of AIDS in Panama and they detail the incidence according to sex, place of residence, the mode of contagion and mortality. They point out that in children less than four years of age the infection occurred more frequently in girls, while it affected boys and men, predominantly, in all other age groups. Furthermore, since 1991 there was an increase in the number of affected women and men and the pattern of mainly homosexual mode of transmission changed to a heterosexual one. Since the majority of patients were between 20 and 40 years of age and the incubation period of the disease ranges from 5 to 10 years, it is assumed that infection occurred in adolescence in many patients. Infection occurred by sexual exposure (homo-hetero-or bisexual) in the majority of patients and less frequently by blood products (hemophiliacs, i.v. drug users) and or perinatally.
