• Hepatitis B
The increase in hepatitis B cases since 2012 was contributed by increased awareness among medical
practitioners to screen and report hepatitis cases. The notification rate of Hepatitis B was 15.41 per
100,000 populations in 2017, higher than in 2016. The number of cases among Malaysians born after
1989 (year of the hepatitis B immunization started in national immunization schedule) was 265 in 2017
compared to 557 in 2016. Most Hepatitis B patients (97.9 per cent) were 18 years and older.
