Possible transmission route of HBV

in KSA1-Horisontal transmission (person to person) is the main transmission route

2-Perintal transmission (positive HBSAG mothers) especially if they are HBEAG positive

3- Heterosexual transmission

4-Illegal injection drug use

5- Contaminated equipment used for therapeutic injections and other health care related procedures

6- Folk medicine practice

7-Blood and blood products transfusion without prior screening

PREVENTION STRATEGIES OF

MINISTRY OF HEALTH IN KSA

Introducing HBV vaccine in EPI program; and

Mandatory screening of blood donors

and expatriates.

Vaccination of risk groups.

Health education especially among

medical personnel.

History of HBV infection control

in KSA

Vaccination of

All infants

At birth

Vaccination of

all children

at school entry

vaccination of

All risk groups

Prevention Of HCV Transmission

Avoiding shared use of Razors or brushes

and any item that pierces the skin.

Strict adherence of the universal

precautions in health facilities.

Educating and training of HCW’s to the

proper use of standard precautions
