Progress Toward Measles Elimination - Eastern Mediterranean Region, 2013-2019.

In 1997, during the 41st session of the Regional Committee for the Eastern Mediterranean, the 21 countries in the World Health Organization (WHO) Eastern Mediterranean Region* (EMR) passed a resolution to eliminate† measles (1). In 2015, this goal was included as a priority in the Eastern Mediterranean Vaccine Action Plan 2016-2020 (EMVAP) (2), endorsed at the 62nd session of the Regional Committee (3). To achieve this goal, the WHO Regional Office for the Eastern Mediterranean developed a four-pronged strategy: 1) achieve ≥95% vaccination coverage with the first dose of measles-containing vaccine (MCV1) among children in every district of each country through routine immunization services; 2) achieve ≥95% vaccination coverage with a second MCV dose (MCV2) in every district of each country either through implementation of a routine 2-dose vaccination schedule or through supplementary immunization activities§ (SIAs); 3) conduct high-quality, case-based surveillance in all countries; and 4) provide optimal measles clinical case management, including dietary supplementation with vitamin A (4). This report describes progress toward measles elimination in EMR during 2013-2019 and updates a previous report (5). Estimated MCV1 coverage increased from 79% in 2013 to 82% in 2018. MCV2 coverage increased from 59% in 2013 to 74% in 2018. In addition, during 2013-2019, approximately 326.4 million children received MCV during SIAs. Reported confirmed measles incidence increased from 33.5 per 1 million persons in 2013 to 91.2 in 2018, with large outbreaks occurring in Pakistan, Somalia, and Yemen; incidence decreased to 23.3 in 2019. In 2019, the rate of discarded nonmeasles cases¶ was 5.4 per 100,000 population. To achieve measles elimination in the EMR, increased visibility of efforts to achieve the measles elimination goal is critically needed, as are sustained and predictable investments to increase MCV1 and MCV2 coverage, conduct high-quality SIAs, and reach populations at risk for not accessing immunization services or living in areas with civil strife.

Rotavirus is the leading cause of hospitalizations for severe acute gastroenteritis among Afghan children <5 years old.

BACKGROUND: Rotavirus gastroenteritis is estimated to cause approximately five thousand deaths annually among Afghan children under 5 years old. Because laboratory confirmation of rotavirus is not routinely performed in clinical settings, assessing the precise burden of disease attributable to severe rotavirus gastroenteritis typically requires active surveillance efforts. This study describes the current burden of pediatric hospitalizations attributable to rotavirus gastroenteritis among Afghan children using surveillance data collected from 2013 to 2015. METHODS: Rotavirus surveillance was conducted from January 2013 through December 2015 at two of the largest hospitals in the country, Indira Gandhi Children Hospital in Kabul and Herat Regional Hospital. Children between 1 and 60 months of age who were admitted to these hospitals for diarrhea were consented and enrolled. Information on age, gender, and seasonality were collected. Stool specimens were collected and tested by enzyme immunoassay for the presence of rotavirus at the central public health laboratory in Afghanistan. RESULTS: Overall, 1,413 of 2,737 (52%) of hospitalized children under five years old with diarrhea were rotavirus cases. The overwhelming majority of rotavirus hospitalizations occurred in children younger than two years of age (93%) while 42% of all rotavirus hospitalizations occurred in children between 6 and 11 months of age. Rotavirus transmission occurred year-round. CONCLUSIONS: Rotavirus is a major cause of severe acute gastroenteritis hospitalizations in young Afghan children, responsible for over half of diarrheal hospitalizations in this population. The Afghanistan Ministry of Public Health has prioritized reducing child mortality by 2020 and is actively working towards the introduction of rotavirus vaccination in Afghan children. These data will be instrumental in understanding the potential impact upon child health that may be achieved through the introduction of rotavirus vaccines in Afghanistan.
