The Sabah Health department recorded more than 1,000 cases of Hepatitis B annually in the past five years.
Its director, Datuk Dr Christina Rundi, said 1,168 cases were recorded in 2014 followed by 1,004 cases in 2015; 1,369 in 2016 1,322 in 2017, and 1,281 last year.
Hepatitis B can cause scarring to the liver, and possibly lead to liver failure and cancer.
“Most of the cases are among adults who did not receive immunisation when they were younger, especially those born before 1989 which was also the year when scheduled vaccination was introduced.
The total number of cases received could also indicate that there are more in the society who would not know whether they have Hepatitis B or not,” she said during the state-level World Hepatitis B event at the Health Ministry’s training institute here.
Dr Christina said several measures were being taken, including conducting screenings for expecting mothers in both rural and urban areas.
“Scheduled vaccinations are given to newborns, one-month-olds and six-month-olds,” she said.
Dr Christina said notifications of Hepatitis C remained low.
“We received 59 cases in 2017 and it dropped to 47 cases last year. So far this year, we have seen 43 cases,” she said, adding that there was no vaccination or treatment for Hepatitis C.
