Surveillance Surveillance

The process of systematic collection, collation and analysis of data with

prompt dissemination to those who need to know, for relevant action to be

taken.

Protocol for the Assessment of National Communicable Disease Surveillance and Response Systems. Guidelines for Assessment TeamsWHO/CDS/CSR/ISR/2001.2

Surveillance that identifies persons with

conditions, infections, diseases

that often have overlapping risk factors,

to achieve better public health interventions ‘Provisional Definition’

What is Integrated Surveillance ?What is Integrated Surveillance ?

Reasons to Combine Reasons to Combine Viral Hepatitis, HIV/AIDS and STD Viral Hepatitis, HIV/AIDS and STD

Surveillance, Control, and Prevention Surveillance, Control, and Prevention

• Major public health problems

• Routes of transmission overlap

• Effective prevention tools

– Immunization, treatment, risk reduction

• Lack of national programs for integrated prevention activities leads to transmission of viral hepatitis, HIV/AIDS and STD

Main principles for integrated sentinel Main principles for integrated sentinel surveillance buildingsurveillance building

• Populations under surveillance: IDUs, SW, Prisoners, Pregnant, Clients of STD clinics, MSM, Donors, Police.

• Comprehensive Integrated sentinel surveillance sites selection

• Site specific samples size calculation

• Unified outreach (response driven sampling)

• Standardize Laboratory Methods

• Standard Reporting (Computerized)

• Unified timelines

Challenges Challenges

• Funding and/or referral sources for: vaccines, lab tests, medical care

• Funding of prevention services flows through separate programs (hepatitis, HIV/AIDS, STD, immunization, corrections)

• Staff of other programs (HIV/AIDS, STD, drug treatment, corrections) may not see viral hepatitis and STI prevention as part of their job

• Incorporation of viral hepatitis and STI prevention messages into “client-centered” counseling

Integrating prevention services for viral hepatitis, HIV/AIDS,STDs and

drug abuse is

GOOD PUBLIC HEALTH
