Summary of published disease outbreak news reports
This is a summary of the disease outbreak news (DON) reports that have been published in July and August 2022. DON reports are WHO's mechanism for publicly disseminating authoritative and independent timely information under the International Health Regulations (IHR 2005) on new and confirmed acute public health events. (2)
During July and August 2022, 6 DON reports, covering 6 events, were published. One event (severe acute hepatitis) involved outbreaks occurring in multiple countries, while the others were from the WHO African Region (3 events), the WHO Eastern Mediterranean Region (1 event), and the WHO South-East Asian Region (1 event). This is a not a reflection on all events occurring globally but on events where a need was determined for publishing further epidemiological information.

Between 23 April and 3 July 2022, a total of 5 (4 confirmed and 1 probable) cases of Ebola virus disease (EVD), (3) including 5 deaths (case fatality rate (CFR) 100%) were reported. On 4 July 2022, the Ministry of Health of the Democratic Republic of the Congo declared the end of the EVD outbreak that affected Mbandaka and Wangata health zones (Equateur province). In accordance with WHO recommendations, the declaration was made 42 days (twice the maximum incubation period) after the burial of the last confirmed case who died in the community. For more information on the EVD outbreak, refer to the previous reports. (4)
Acute hepatitis of unknown etiology in children, multiple countries
From 5 April to 8 July 2022, 35 countries in 5 WHO Regions reported a cumulative number of 1010 probable cases of severe acute hepatitis of unknown etiology in children, (5) which fulfill the WHO case definition, (6) including 46 cases requiring liver transplants and 22 deaths. Between 24 June and 8 July 2022, 90 new probable cases and 4 deaths were reported to WHO. Almost half (48%) of the probable cases have been reported from the WHO European Region, while one-third of global cases (33%) have been reported from the Region of the Americas, primarily from the United States of America. The Western Pacific Region, the South-East Asia Region, and Eastern Mediterranean Region reported fewer than 7% of global cases each.
On 11 July 2022, WHO launched a global survey with an aim to estimate the incidence of severe acute hepatitis of unknown etiology in 2022 compared to the previous 5 years, to understand where cases and liver transplants are occurring at higher-than-expected rates.
Cholera in Somalia (7) is endemic with recurrent outbreaks reported since 2017. Between 1 January and 10 July 2022, a cumulative number of 7796 cases of cholera including 37 associated deaths (CFR 0.5%) were reported from 25 drought-affected districts.
