Hepatitis B in Malaysia, and why the vaccine list describes a mover

NaTHNaC's assessment: “This country is considered to have an intermediate or high prevalence of hepatitis B.”

It describes the virus as “a viral infection spread through blood, semen and vaginal fluids. This mostly occurs during sexual contact or as a result of blood-to-blood contact (for example from contaminated equipment during medical and dental procedures, tattooing or body piercing procedures, and sharing of intravenous needles).” It adds that “mothers with the virus can also pass on the infection to their baby during childbirth.”

Unlike food- and water-borne risks, hepatitis B is not about where you eat. It is about blood and body fluids — which means medical and dental care, cosmetic procedures, and sex.

NaTHNaC says vaccination “could be considered for all travellers and is recommended for those whose activities or medical history put them at increased risk.” Its list includes:

• long-stay travellers
• people at high risk of needing medical or dental procedures or hospitalisation — “e.g. those with pre-existing medical conditions, those who may require travelling for medical care abroad, or those travelling to visit families or relatives”
• people who may be exposed to blood or body fluids through their work, such as health and aid workers
• people taking part in contact sports
• people who may have unprotected sex, or be exposed to contaminated needles

Read as a whole, that list describes the people who move to Malaysia remarkably well: long stays, an older cohort on the retirement routes who are more likely to have existing conditions, and people who come partly for medical care.

NaTHNaC's prevention advice is to avoid contact with blood or body fluids, which it breaks down into specific situations:

• avoiding unprotected sexual intercourse
• avoiding tattooing, piercing, public shaving and acupuncture unless sterile equipment is used
• not sharing needles or other injection equipment
• following universal precautions in a healthcare or higher-risk work setting

For a visitor these are rare events. For a resident they are ordinary life: a barber, a dentist, a tattoo after a year in Penang, a course of acupuncture for a bad back. None of them is reckless. Each is a place where sterile equipment is the thing that matters.

NaTHNaC also notes that a sterile medical equipment kit may be helpful when travelling to resource-poor areas — relevant for trips into the interior rather than city life.

NaTHNaC's mention of “those with pre-existing medical conditions” deserves a direct answer from our side, because it is the point where people misread what a plan does. Pre-existing conditions are excluded on the cover we arrange. If part of the reason for living in Malaysia is ongoing treatment for something you already have, that treatment sits outside the plan. Hepatitis B caught after you join is a new infection; the condition you arrived with is not covered either way.

Two further limits connect to this page. Pregnancy and childbirth are excluded, which matters given that the virus can pass from mother to baby at birth. And the vaccine is usually your cost: vaccinations are not covered on Major Medical or Standard, with US$250 at 25% co-insurance on Comprehensive and US$500 on Fully Comprehensive.

Public treatment is charged at the Ministry of Health's foreigner rates — RM40 outpatient, RM120 specialist, RM100 emergency — and private hospitals charge private rates. The cover we arrange is worldwide — the United States is the one exception.
