Disease Outbreaks

WHO disease outbreak news
  1. From 9 through 30 April 2019, the National International Health Regulations (IHR) Focal Point of Saudi Arabia reported nine additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, including three deaths.
  2. Although the security situation has subsided mildly into an unpredictable calm, the transmission of Ebola virus disease (EVD) continues to intensify in North Kivu and Ituri provinces with more than 100 confirmed cases reported this week.

    The main drivers behind the continued rise in cases stems from insecurity hampering access to critical hotspot areas, persistent pockets of poor community acceptance and hesitation to participate in response activities, and delayed detection and late presentation of EVD cases to Ebola Treatment Centres (ETCs)/Transit Centres (TCs).
  3. On 9 May 2019, the Ministry of Health (MOH) in Singapore notified WHO of one laboratory-confirmed case of monkeypox. The case-patient is a 38 year old Nigerian man who arrived in Singapore on 28 April 2019 and attended a workshop from 29-30 April. Prior to his travel to Singapore, he had worked in the Delta state in Nigeria, and had attended a wedding on 21 April 2019 in a village in Ebonyi State, Nigeria.

    The patient developed fever, muscle aches, chills and skin rash on 30 April. He reported that he had remained in his hotel room most of the time between 1 and 7 May. He was transferred to a public hospital by ambulance on 7 May and referred to the National Centre for Infectious Diseases (NCID) on the same day, where he was isolated for further management. Skin lesion samples were taken on 8 May and tested positive for monkeypox virus by the National Public Health Laboratory on the same day. He is currently in a stable condition.
  4. On 4 January 2019, the National IHR Focal Point for France informed WHO of five human autochthonous cases of Rift Valley Fever (RVF) diagnosed on Mayotte Island through the Early Warning and Response System of the European Union. The dates of symptom onset ranged from 22 November to 31 December 2018.

    From November 2018 to 03 May 2019, 129 confirmed human Rift Valley Fever (RVF) cases and 109 animal foci (23 small ruminants and 86 bovine) have been reported in Mayotte. After a steady decline in cases during the last three weeks of March 2019, a slight increase has been observed in April 2019. As of 3 May 2019, one new human case but no new animal foci have been reported. Both human RVF cases and animal foci are mainly located in the center and the north west of the main island Grande-Terre. However, since the end of March 2019, a few new animal foci have also been detected in the east of Grande-Terre and in Petite Terre of Mayotte.
  5. From 1 March through 8 April 2019, the National International Health Regulations (IHR) Focal Point of Saudi Arabia reported 45 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, including 13 deaths.
  6. The Ebola virus disease (EVD) outbreak response this past week continues to be hampered by insecurity. On 3 May in Katwa, a Safe and Dignified Burial (SDB) team was violently attacked following the completion of a burial for a deceased EVD case. In Butembo and surrounding health zones, response activities were repeatedly halted due to a number of serious security incidents taking place from 4-6 May. On 8 May, a group of over 50 armed militia infiltrated the city centre. Security forces repelled the attack following intense gunfire in close proximity to staff accommodations. Although activities resumed on 9 May, after almost five consecutive days of suspension, threats of further attacks against EVD response teams and facilities remain prevalent.

    These security incidents, and especially the resultant lack of access to EVD affected communities, remain a major impediment to the response, with teams unable to perform robust surveillance nor deliver much needed treatment and immunisations. The ongoing violent attacks sow fear, perpetuate mistrust, and further compound the multitude of challenges already faced by frontline healthcare workers. Without commitment from all groups to cease these attacks, it is unlikely that this EVD outbreak can remain successfully contained in North Kivu and Ituri provinces.
  7. From 1 January through 30 April 2019, the Ministry of Health in Tunisia responded to a large measles outbreak in the country. A total of 3 141 suspected cases, of which 909 (28.9%) were laboratory confirmed and 1 236 (39.4 %) epidemiologically linked cases including 30 deaths (case fatality ratio=1.0 %), have been reported in all of the 24 governorates (range 1 – 1 274). The majority of cases were reported from Kasserine (1 274 cases) and Sfax (212 cases) governorates. In April 2019, four additional governorates were particularly affected with 155, 116, 93 and 69 cases reported from Kairouan, Tunis, Sousse and Nabeul respectively.

    The two most affected age groups were those older than 15 years (31%) and infants between the age of 6 and 12 months (28%). The male: female ratio was 1.2. Eighty four percent of affected children between 1 and 5 years were not vaccinated. Death was reported in 30 cases ranging in age from 15 days to 41 years of age (median, 7.5 months).
  8. Globally, between 2016 and 2017, the number of reported measles cases increased by 31%, while in the WHO Western Pacific Region (WPR), the total number of cases reported decreased by 82% during the same period. However, there was an increase in cases reported in WPR, from 11 118 in 2017 to 26 163 cases in 2018. A resurgence of measles cases has been seen in all WHO Regions. An unusually high number of cases reported from countries and areas of the WPR in 2019 have been reported from: 1) several countries/areas where measles has been eliminated due to importation-related outbreaks; and 2) endemic countries such as the Philippines which has ongoing measles outbreak. In WPR, currently nine countries and areas (Australia, Brunei Darussalam, Cambodia, Hong Kong SAR (China), Japan, Macao SAR (China), New Zealand, the Republic of Korea, and Singapore) are verified by the Regional Verification Commission for Measles Elimination as having interrupted endemic measles virus transmission for more than 36 months.

    To date, there have been no measles cases reported from the Pacific Island Countries and areas. The majority of countries and areas in WPR have made positive inroads to improve immunization and achieve higher vaccination coverage at the national level. However, with global resurgence of measles and movement of populations, several countries and areas in WPR remain vulnerable to outbreaks of measles due to low coverage of measles-containing-vaccine (MCV), at the subnational level and among vulnerable populations.
  9. In the first two months of 2019, 34 300 measles cases have been reported in 42 countries of the WHO European Region, including 13 measles-related deaths in three countries (Albania, Romania and Ukraine). The majority of cases are reported in Ukraine, with more than 25 000 cases (>70%)1.

    As of 28 March 2019, the WHO European Region reported a total of 83 540 measles cases and 74 related deaths for 2018. This is compared to 25 869 cases and 42 deaths in 2017, and 5 273 cases and 13 deaths in 2016. In 2018, eight countries reported over 2 000 cases each including Ukraine (n= 53 218), Serbia (n=5 076), Israel (3 140), France (n=2 913), Italy, (n=2 686), Russian Federation (n=2 256), Georgia (n=2 203) and Greece (n=2 193).
  10. The operating environment has become increasingly insecure and socio-politically complex. Insecurity remains a major impediment to ensuring timely response interventions in the affected communities. Ebola virus disease (EVD) response activities in Butembo and Katwa remained limited; however, these are gradually resuming following a comprehensive reinforcement of security measures and community engagement efforts. The overall security situation, nevertheless, remains volatile. While no significant injuries or damages are reported this week, access and activities in parts of Mandima, Masereka, Kalunguta and Vuhovi, remain irregular due to the presence of armed groups and other security concerns. New EVD cases are expected to continue to increase, in tandem with incidents of insecurity in these hotspot areas over the coming weeks, placing significant strain on response teams and the security resources available to secure their movements.

    Incidence of EVD cases in the Democratic Republic of the Congo this week saw a considerable, although not unexpected, rise compared to the week prior. This observation is in line with previous instances where a disruption to response activities was followed by a spike in the number of new cases. Transmission remains most intense in the Katwa, Butembo, and Mandima hotspot areas (Figure 1 and Table 1). In addition, notable recurring re-introduction events having been documented in previously affected health zones such as Mabalako and Musienene, followed by local amplification and extension to affect new heath areas. In the 21 days between 10 – 30 April 2019, 70 health areas within 15 health zones reported new cases; 45% of the 157 health areas affected to date (Table 1 and Figure 2). During this period, a total of 292 confirmed cases were reported, the majority of which were from the health zones of Katwa (47%, n=137), Butembo (13%, n=38), Mandima (11%, n=32), Mabalako (7%, n=20), and Musienene (6%, n=17).
