The incubation period of the hepatitis B virus is 75 days on average, but can vary from 30 to 180 days.

The strategy highlights the critical role of universal health coverage and sets targets that align with those of the Sustainable Development Goals.


And in the WHO Region of the Americas, 0.7% of the population is infected.Hepatitis B is also spread by needlestick injury, tattooing, piercing and exposure to infected blood and body fluids, such as saliva and, menstrual, vaginal, and seminal fluids. Hepatitis B virus-specific T cell responses after stopping nucleos(t)ide analogue therapy in HBeAg negative chronic hepatitis B.

Since 2015, WHO has recommended treatment for everyone diagnosed with HIV infection, regardless of the stage of disease. Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV). Therefore, most people who start hepatitis B treatment must continue it for life. They can be used to distinguish acute and chronic infections.Laboratory diagnosis of hepatitis B infection focuses on the detection of the hepatitis B surface antigen HBsAg. The date of 28 July was chosen because it is the birthday of Nobel-prize winning scientist Dr Baruch Bloomberg, who discovered the hepatitis B virus and developed a diagnostic test and vaccine for it. The report sets out global statistics on viral hepatitis B and C, the rates of new infections, the prevalence of chronic infections and mortality caused by these 2 high-burden viruses, and coverage of key interventions, all current as at the end of 2016 and 2017.Moreover, since 2011, together with national governments, partners and civil society, WHO has organized annual World Hepatitis Day campaigns (as 1 of its 9 flagship annual health campaigns) to increase awareness and understanding of viral hepatitis. For HBeAg-negative patients with chronic hepatitis B disease, treatment can be administered when the HBV DNA is at or above 2,000 IU/mL (10 4 copies/mL) and the serum ALT is elevated (ALT levels >20 U/L for females; 30 U/L for males) for 3-6 months.. In high-income countries, surgery and chemotherapy can prolong life for up to a few years.

In addition, WHO recently published the “Progress report on HIV, viral hepatitis and sexually transmitted infections, 2019”, outlining its progress towards elimination.

Preventing hepatitis B infection averts the development of complications including the development of chronic disease and liver cancer.Hepatitis B prevalence is highest in the WHO Western Pacific Region and the WHO African Region, where 6.2% and 6.1% of the adult population is infected respectively.

However, some people have acute illness with symptoms that last several weeks, including yellowing of the skin and eyes (jaundice), dark urine, extreme fatigue, nausea, vomiting and abdominal pain.

Mar. Unsafe injections decreased from 39% in 2000 to 5% in 2010 worldwide. Children less than 6 years of age who become infected with the hepatitis B virus are the most likely to develop chronic infections.About 1% of persons living with HBV infection (2.7 million people) are also infected with HIV. Treatment for hepatitis B differs for chronic and acute infections. Actions to be taken by countries and the WHO Secretariat to reach these targets are outlined in the strategy.To support countries in achieving the global hepatitis elimination targets under the Sustainable Development Agenda 2030, WHO is working to:These guidelines also recommend lifelong treatment for those with cirrhosis and those with high HBV DNA and evidence of liver inflammation, and regular monitoring for those on treatment, as well as those not yet on treatment for disease progression, indications for treatment and early detection of liver cancer.In July 2020 WHO published  additional guidance on In addition to the series of hepatitis B vaccinations (including a first dose within 24 hours of birth), WHO now recommends that pregnant women testing positive for HBV infection (HBsAg positive) with an HBV DNA equal to or greater 200,000 IU/mlSome settings have poor access to tests that quantify an individual’s HBV viral load and determine whether a pregnant woman would be eligible for preventative treatment or prophylaxis.
In 2016, of the more than 250 million people living with HBV infection, 10.5% (27 million) were aware of their infection.

Furthermore, safer sex practices, including minimizing the number of partners and using barrier protective measures (condoms), also protect against transmission.In May 2016, the World Health Assembly adopted the first The strategy has a vision to eliminate viral hepatitis as a public health problem. The median price of WHO-prequalified generic tenofovir on the international market fell from US$ 208 per year to US$ 32 per year in 2016.In most people, however, the treatment does not cure hepatitis B infection, but only suppresses the replication of the virus.
