Despite slightly fewer cases reported during the past week (Figure 1), current epidemiological indicators highlight that the Ebola virus disease (EVD) outbreak is continuing with moderate intensity. Katwa and Butembo remain the major health zones of concern, while simultaneously, small clusters continue to occur in various geographically dispersed regions. During the last 21 days (23 January – 12 February 2019), 97 new cases have been reported from 13 health zones (Figure 2), including: Katwa (59), Butembo (12), Beni (7), Kyondo (4), Oicha (4), Vuhovi (3), Biena (2), Kalunguta (2), Komanda (1), Manguredjipa (1), Mabalako (1), Masereka (1), and Mutwanga (1).1 The recent case reported in the Komanda health zone was a resident of Katwa who was exposed to the virus, and subsequently travelled to both Bunia and Komanda. This case comes one month after the last reported case in Ituri Province; underscoring the high risks of reintroduction to previously affected areas, as well as the potential for spread to new ones.
As of 12 February, 823 EVD cases2 (762 confirmed and 61 probable) have been reported, including 517 deaths (overall case fatality ratio: 63%). Cumulatively, cases have been reported from 118 of 287 health areas across 18 health zones, of which 37 health areas have reported a case in the last 21 days. Thus far, 283 people have been discharged from Ebola Treatment Centers (ETCs) and enrolled in a dedicated monitoring and support programme. One new health worker infection was reported in Katwa. To date, a total of 68 health workers have been infected. [leia mais]
Brazil is currently in the seasonal period for yellow fever, which occurs from December through May. The expansion of the historical area of yellow fever transmission to areas in the south-east of the country in areas along the Atlantic coast previously considered risk-free led to two waves of transmission (Figure 1). One during the 2016–2017 seasonal period, with 778 human cases, including 262 deaths, and another during the 2017–2018 seasonal period, with 1376 human cases, including 483 deaths.
From December 2018 through January 2019, 361 confirmed human cases, including eight deaths, have been reported in 11 municipalities of two states of Brazil. In the southern part of São Paulo state, seven municipalities:El dorado (16 cases), Jacupiranga (1 case), Iporanga (7 cases), Cananeia (3 cases), Cajati (2), Pariquera-Açu (1), and Sete Barras (1) reported confirmed cases. In the same state, additional cases in Vargem (1) and Serra Negra (1) municipalities were confirmed on the border with Minas Gerais State. Additionally, two cases have been confirmed in the municipalities of Antonina and Adrianópolis, located in the eastern part of Paraná State. These are the first confirmed yellow fever cases reported since 2015 from Paraná, a populous state with an international border. Among these confirmed cases, 89% (32/36) are male, the median age is 43 years, and at least 64% (23/36) are rural workers. [leia mais]

The Ebola virus disease (EVD) in the Democratic Republic of the Congo continues with relatively high numbers of cases reported in recent weeks (Figure 1), and some encouraging signs. Katwa and Butembo health zones remain the epicentres of the outbreak, reporting 71% of cases in the last three weeks, with smaller clusters continuing to occur concurrently across a geographically dispersed area.
As of 5 February, 789 EVD cases1 (735 confirmed and 54 probable) have been reported, including 488 deaths (overall case fatality ratio: 62%). Thus far, 267 people have been discharged from Ebola Treatment Centres (ETCs) and enrolled in a dedicated monitoring and support programme. Among cases with available information regarding age and sex, 58% (454/788) were female, and 30% (232/786) were aged less than 18 years; including 116 children under five years. Five new health worker infections were reported in Katwa (4) and Kalunguta (1); overall 67 health workers have been affected to date. [leia mais]

The Ministry of Health (MoH), WHO and partners have continued to face challenges in the containment and control of the Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo. The number of reported cases increased during recent weeks, most notably from the Katwa health zone where response teams have faced pockets of community mistrust. The outbreak has also extended southwards to Kayina health zone, a high security risk area. Teams are working actively to build community trust and scale up response activities around these new clusters.
Figure 1 shows that as of 22 January 2019, there have been a total of 713 EVD cases1 (664 confirmed and 49 probable), including 439 deaths (overall case fatality ratio: 62%). Thus far, 247 people have been discharged from Ebola Treatment Centres (ETCs), with many having enrolled in a dedicated program for monitoring and supporting survivors. Among cases with a reported age and sex, 59% (420/710) of cases were female, and 30% (214/708) were aged less than 18 years; including 108 infants and children under 5 years. Sixty-one healthcare workers have been infected to date. [leia mais]
On 19 December 2018, the Argentinian Ministry of Health and Social Development issued an epidemiological alert regarding an increase in cases of hantavirus pulmonary syndrome (HPS) in Epuyén, Chubut Province. Between 28 October 2018 – 20 January of 2019, a total of 29 laboratory-confirmed cases of HPS, including 11 deaths have been reported in Epuyén, Chubut Province. Epuyén has a population of approximately 2 000 persons, and Chubut Province is located in Patagonia in southern Argentina.
The index case had environmental exposure prior to symptom onset on 2 November, and subsequently attended a party on 3 November. Six cases who also attended the party experienced the onset of symptoms between 20-27 November 2018. An additional 17 cases, all of whom were epidemiologically-linked to previously confirmed cases, experienced symptom onset between 7 December 2018 and 3 January 2019 (Figure 1). Potential human-to-human transmission is currently under investigation. [leia mais]
The Ministry of Health (MoH), WHO and partners continue to respond to the ongoing Ebola virus disease (EVD) outbreak in one of the most complex settings possible. A high number of cases are still being reported, most notably from the metropolitan areas of Katwa Health Zone during the past week. The decline in case incidence has continued in Beni; a positive indication of how effective the response can be despite multiple challenges.
Trends in the number of new cases occurring (Figure 1) reflect the continuation of the outbreak across a number of geographically dispersed areas. During the last 21 days (26 December 2018 through 15 January 2019), 79 new cases have been reported from 11 health zones (Figure 2), including: Katwa (36), Oicha (14), Butembo (11), Beni (4), Mabalako (4), Kalungata (3), Kyondo (3), Komanda (1), Musienene (1), Biena (1) and Manguredjipa (1). The latter is a newly affected health zone, although the case likely acquired the infection in Mabalako Health Zone. [leia mais]

As of October 2018, genetically-linked circulating vaccine-derived poliovirus type 2 (cVDPV2) isolates were detected in two cases from Haut-Katanga province (Mufunga-Sampwe district) in the Democratic Republic of the Congo. The first case was a 11-year old child who experienced onset of acute flaccid paralysis (AFP) on 6 October. The second case was a 29-month old child who experienced onset of symptoms on 7 October, and is a known contact of the first case. The isolated viruses are a new emergence and unrelated to previously-detected cVDPV2s affecting the country. This is the fourth distinct outbreak of cVDPV2 detected in the country since June 2017. In total, 42 cVDPV2 cases have now been confirmed since detection of the first outbreak in June 2017, 20 cases of which were detected in 2018.
In February 2018, the government declared cVDPV2 to be a national public health emergency. On 26 July 2018, the Minister of Health, WHO Director General, the Regional Director for Africa, and provincial governors convened an urgent, high-level meeting and signed the ‘Kinshasa Declaration for Polio Eradication’. Provincial governors pledged to provide the necessary oversight, accountability and resources required to urgently improve the quality of the outbreak response being implemented across the country. It is imperative that the remaining operational gaps in outbreak response are urgently filled with the appropriate oversight and engagement. [leia mais]
The Panama Ministry of Health has reported an increase in cases of hantavirus infection in Los Santos Province, Republic of Panama, to the Pan American Health Organization / World Health Organization (PAHO/WHO). Between 1 January and 22 December 2018, a total of 103 confirmed cases of hantavirus have been reported at the national level, 99 of which were reported in Los Santos Province.

Cases were confirmed by serology and polymerase chain reaction (PCR)3. Sequencing determined that the type of virus associated with this outbreak is Choclo virus. It was first isolated in 1999 in the western Republic of Panama. [leia mais]
The response by WHO and partners to the ongoing Ebola virus disease (EVD) outbreak continues despite disruptions to key services due to security incidents taking place in Beni and Butembo during the recent election on 30 December 2018. In order to ensure the safety of all staff deployed, as a precautionary measure, operations were scaled back for a few hours on election day. All normal operations have been fully restored as of 1 January 2019. After an intensification of field activities in early December, notable improvements can be observed in many areas, notably a decrease in cases in Beni. However, hard-earned progress could still be lost to rebound levels of transmission resulting from prolonged periods of insecurity hampering containment efforts.
During the reporting period (27 December 2018 – 2 January 2019), 16 newly confirmed cases were reported from Beni (two), Butembo (five), Katwa (three), Komanda (one), Mabalako (one), and Oicha (four) health zones (Figure 1). As of 2 January 2019, there have been a total of 609 EVD cases1 (561 confirmed and 48 probable, Figure 2), including 370 deaths and 208 people having recovered. Overall, cases are occurring in localised hotspots within 16 health zones found in North Kivu and Ituri. Amongst confirmed and probable cases, the case load has been highest in females aged 15-49 who are eligible for vaccination (i.e. non-pregnant), and also females aged 50 years and older (Figure 3). Amongst confirmed and probable cases, 61% (374/609) were female (median age = 28) and were predominantly older than male cases (median age = 25.5). Of note, 16% (96/607) of cases were among children less than five years old, and 7% (41/607) were infants less than one year old. Most of the cases among children aged five years old or more were from Beni, 48% (46/96). There were 29 cases among pregnant women, of which 14 were from Beni. Fifteen of the 29 cases were reportedly breastfeeding women. [leia mais]
