Programme mondial de lutte contre l’hépatite. Les mesures à prendre par les pays et par le Secrétariat de l’OMS pour atteindre ces cibles sont présentées dans la Stratégie. L’amélioration de l’assainissement, la sécurité sanitaire des aliments et la vaccination sont les façons les plus efficaces de lutter contre l’hépatite A. Les moyens suivants permettent de réduire la propagation du virus : Plusieurs vaccins injectables inactivés contre l’hépatite A sont disponibles sur le marché international. Le virus peut également se transmettre par contact physique étroit avec une personne infectée (par exemple lors de rapports sexuels oraux ou anaux), mais il ne se propage pas à l’occasion des contacts ordinaires entre The strategy highlights the critical role of Universal Health Coverage and the targets of the strategy are aligned with those of the Sustainable Development Goals. living in a household with an infected person; being a sexual partner of someone with acute hepatitis A infection; travelling to areas of high endemicity without being immunized. WHO announces development of new guidance on Hepatitis C self-testing, WHO-commissioned global systematic review finds high HCV prevalence and incidence among men who have sex with men, Strategic exchange with representatives from civil society and communities, Welcome to 2020 – the decade for disease elimination, What cure means - story of people cured of HCV, Coronavirus disease outbreak (COVID-2019), Coronavirus disease outbreak (COVID-19) », Countries with immunization schedules that include hepatitis A.

It can be acute or chronic. Among older children and adults, infection usually causes more severe symptoms, with jaundice occurring in more than 70% of cases. HAV is transmitted through direct person- to-person contact (fecal–oral transmission) or through ingestion of contaminated food or water. Countries with low endemicity may consider vaccinating high-risk adults. They can be also prolonged, affecting communities for months through person-to-person transmission. Waterborne outbreaks, though infrequent, are usually associated with sewage-contaminated or inadequately treated water. In high-income countries with good sanitary and hygienic conditions, infection rates are low. des nausées, une gêne abdominale, des urines foncées et un ictère (coloration jaune de la peau et du blanc de l’œil).

Vaccination against hepatitis A should be part of a comprehensive plan for the prevention and control of viral hepatitis. Le virus de l’hépatite A est l’une des causes The report sets out global statistics on viral hepatitis B and C, the rate of new infections, the prevalence of chronic infections and mortality caused by these 2 high-burden viruses, as well as coverage of key interventions, all current as at the end of 2016 and 2017.Since 2011, together with national governments, civil society and partners, 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.
