An estimated 325 million people are living with hepatitis B or C and few are aware of their condition. Death tolls from the viruses are rising, says the UN.
The World Health Organisation’s (WHO) latest hepatitis report identifies the condition as a grave public health threat that needs an “urgent response.”
Hepatitis killed 1.34 million people in 2015, a toll roughly in-line with HIV and tuberculosis.

But in contrast to HIV and TB, hepatitis deaths are increasing, the WHO says, recording a 22% mortality rise from 2000 to 2014.
Often symptom-free
Hepatitis is often symptom-free, but types B and C can trigger liver cirrhosis and cancer if untreated.

Lack of awareness among those infected is driving the virus’s spread.
For hepatitis B — which is spread through bodily fluids such as blood and semen — only 9% of those infected know their status. And for hepatitis C, primarily spread through blood, just 20% of those infected are aware of their condition. Lack of access to testing and treatment leaves “millions of people at risk of a slow progression to chronic liver disease, cancer and death”, the WHO says in a statement.
Affected regions
The hepatitis B problem is most acute in the WHO’s Western Pacific Region, which includes China, Malaysia and Southeast Asia. An estimated 115 million people in the region have the virus.
Second worst is Africa, with 60 million hepatitis B cases. An effective vaccine exists for hepatitis B.
The WHO’s latest data show that hepatitis C — for which there is no vaccine — is most commonly spread through unsafe injections, notably among drug users.
Europe and the eastern Mediterranean region are afflicted with the most hepatitis C cases at 14 million and 15 million respectively.
The WHO is trying to ramp up the global hepatitis response, aiming to treat some 80% of sufferers worldwide by 2030. AFP
