According to WHO, four suspected measles outbreaks were reported between 21-27 December 2021 in Chinartu, Chora District in Uruzgan, in Suri District in Zabul and in Arghistan District in Kandahar. Reportedly 35 patients suspected with measles symptoms are undergoing medical tests to confirm measles. (OCHA, 9 Jan 2022)

During epidemiological week 4 of 2022 a total of 1,465 new cases (5.5% increase from previous week) and 24 new deaths (100% increase from previous week) were reported. Since epidemiological week 1 of 2022, the trends of new measles cases reported in all provinces has continued to increase sharply. The most affected provinces include Helmand (20.9%), Kandahar (6.9%), Balkh (5.1%), Paktika provinces (4.4%), Ghor (4.3%) and Ghazni (3.9%). A total of 35,609 clinical cases of measles and 3,211 lab confirmed cases are reported between January 2021 to January 2022. A total of 156 confirmed deaths due to measles are recorded during the same period. (WHO, 29 Jan 2022)

From 1 January 2021 to 29 January 2022, 35 319 suspected measles cases were reported in Afghanistan, of which 3221 (9%) were laboratory-confirmed by IgM-ELISA in the seven reference laboratories (one national and six regional). Most of the suspected measles cases (91%) occurred among children less than 5 years of age. During the same period, 156 measles deaths were reported among the confirmed cases (CFR=4.8%), with more than 97% of the fatalities registered among children less than 5 years of age. Although the number of deaths is relatively low, the rapid rise in cases suggests that the trend of reported deaths will continue to increase sharply in the coming weeks. The most affected provinces, with the highest number of reported cases (confirmed and suspected) are Balkh, Ghazni, Helmand, Kandahar, Kabul, Paktika, and Paktya. (WHO, 10 Feb 2022)

From January 2021 to 13 March 2022, there have been 48 366 cases and 250 deaths. In 2022 alone, there have been over 18 000 cases and 142 children have died of measles in the country. More than 1.2 million children aged 6–59 months are planned to be vaccinated during the ongoing measles vaccination campaign in Afghanistan. Around 9200 health workers, volunteers, supervisors, and monitors are mobilized to cover 49 districts in 24 provinces in a week-long campaign scheduled 12–17 March 2022. (WHO, 14 Mar 2022)

During the last two weeks, the measles outbreaks cases showed slight reduction when compared to the preceding two weeks, even though new cases are reported every day. WHO maintains 111 rapid response teams (RRT) on-the-ground to support surveillance and response. Emergency reproductive, maternal and child health services are not readily accessible to a significant part of the vulnerable population due to limited provider capacity, including a weak referral system, an unprecedented level of malnutrition that is making people more vulnerable to illness and diseases like measles. (WHO, 15 Mar 2022)

During the epidemiological weeks 11 and 12, there have been 6,529 cases of measles reported from the sentinel sites of WHO. Most of the cases (80%) were under five years of age and most of them were reported from Helmand, Kabul, Kunduz, Kandahar and Nangarhar provinces. From 12-18 March 2022, the first phase of measles vaccine campaign was conducted in 48 high-risk districts in 24 provinces of Afghanistan. During this campaign, more than 1.2 million children aged 6-59 (50.2% girls) were vaccinated in the targeted districts. The second phase of measles vaccination campaign will be conducted in 111 high-risk districts in 27 provinces. Around 3.5 million children will be targeted in this campaign on the same age group. (WHO, 31 Mar 2022)

The measles outbreak remains a significant concern with 62,185 cases of measles and 330 deaths reported across the country since January 2021. Of the reported cases, around 80 per cent were among children under five. In addition to the measles vaccination campaign, an additional 72,005 children were vaccinated against measles in March under the routine immunization programme, resulting in a total of 157,349 children vaccinated with measles vaccine under the routine programme during the first quarter of 2022. (UNICEF, 31 Mar 2022)

In April 2022, there have been 13,844 new suspected measles cases reported from all over the country.

The nationwide measles vaccine campaign is planned in July - August 2022. (WHO, 14 May 2022)
