A growing risk of outbreaks of measles, pertussis, and other vaccine-preventable diseases in countries affected by Ebola must be countered by urgent scaling up of routine immunization activities. The Ebola outbreak, which has infected some 24 000 people and killed around 10 000 of them, has reduced vaccination coverage in Guinea, Liberia and Sierra Leone, as health facilities and staff focus on halting the outbreak.

WHO/Gary Hampton

Today, WHO issued its first-ever guidance for the treatment of chronic hepatitis B, a viral infection which is spread through blood and body fluids, attacking the liver and resulting in an estimated 650 000 deaths each year. Worldwide, some 240 million people have chronic hepatitis B virus and are at increased risk of dying from cirrhosis and liver cancer.

WHO recommends that all children are vaccinated against hepatitis B, with a first dose given at birth. Effective medicines exist that can prevent people developing these conditions so they live longer.
