Tracing contacts of persons with sexually transmitted diseases in a developing country

Area of Science:

• Public Health
• Epidemiology
• Infectious Disease Control

Background:

• Sexually transmitted diseases (STDs) pose a significant public health challenge.
• Effective contact tracing is crucial for controlling STD transmission.
• Traditional contact tracing methods can be resource-intensive and less efficient.

Purpose of the Study:

• To present a simplified and cost-effective system for tracing contacts of STD patients.
• To evaluate the effectiveness of a contact card system combined with home visits.
• To assess the feasibility of this system within existing health department resources.

Main Methods:

• A contact card system was implemented, given to index STD cases.
• Contacts presenting with cards were treated voluntarily.
• Health assistants conducted home visits for contacts who did not present cards.
• The system's cost and staffing implications were analyzed.

Main Results:

• 341 contacts (19.8%) voluntarily attended clinics using contact cards.
• An additional 367 contacts (21.3%) were reached through home visits.
• The tracing system successfully engaged a total of 708 contacts.
• The initiative incurred no substantial additional costs for the health department.

Conclusions:

• The simplified contact tracing system is effective in identifying and treating STD contacts.
• The use of contact cards and targeted home visits is a feasible and low-cost approach.
• This method can be integrated into existing public health programs without requiring additional staff.
