Key findings
In a global news index covering January 2019 to July 2026, hepatitis took its largest monthly share of news in May 2022, during the international alerts about acute hepatitis of unknown origin in children, at 6.69 articles per 10,000 news articles, 3.3 times its 2019 annual share of 2.03.
Basis: Monthly hepatitis articles divided by all articles in the index for the same month, every month from January 2019 to July 2026; May 2022 alone held 1,046 articles, 26.3% of the year's 3,978.
Hepatitis took 2.08 articles per 10,000 news articles in 2022, 1.93 times its 2021 share of 1.08, the highest annual share between 2019 and 2025.
Basis: Annual hepatitis articles divided by all articles in the index for the same year, complete years 2019–2025.
December 2025, the month in which the United States Advisory Committee on Immunization Practices voted on the birth dose of the hepatitis B vaccine, was the month with the largest hepatitis share of news after mid-2022, at 3.66 articles per 10,000.
Basis: Monthly hepatitis articles per 10,000 news articles, January 2019 – July 2026; only April and May 2022 rank higher.
Between 2019 and 2025, an average of 12.48% of each year's hepatitis news appeared in July, the month of World Hepatitis Day (28 July), 1.5 times the 8.33% expected from an even spread across the year.
Basis: Within-year month shares of the 19,023 matched articles published in the complete years 2019–2025, averaged over those years.
Editors' priority ratings placed 81.5% of hepatitis articles at critical priority (7 or higher on a 1–9 scale) between January 2023 and July 2026, 1.91 times the 42.6% share for all news.
Basis: Top priority label per article; critical = priority ≥ 7.
