Hubble Spots Flock of Cosmic Ducks


This star-studded image shows us a portion of Messier 11, an open star cluster in the southern constellation of Scutum (the Shield). Messier 11 is also known as the Wild Duck Cluster, as its brightest stars form a “V” shape that somewhat resembles a flock of ducks in flight. via NASA https://ift.tt/2CMbhhy

Disease outbreak news from the WHO: Ebola virus disease – Democratic Republic of the Congo

The ongoing Ebola virus disease (EVD) outbreak in the North Kivu and Ituri provinces saw a rise in the number of new cases this past week. At this time, response teams are facing daily challenges in ensuring timely and thorough identification and investigation of all cases amidst a backdrop of sporadic violence from armed groups and pockets of mistrust in some affected communities. Despite this, progress is being made in areas such as Mandima, Masereka and Vuhovi, where response teams are gradually able to access once again and acceptance by the community of proven interventions to break the chains of transmission is observed.

During the last 21 days (6 – 26 March), a total of 125 new cases were reported from 51 health areas within 12 of the 21 health zones affected to date; 38% of the 133 health areas affected to date (Figure 2). The majority of these cases were from remaining hotspot areas of Katwa (36), Butembo (14), and three emerging clusters in Mandima (19), Masereka (18) and Vuhovi (17), in addition to a limited number of cases in other areas (Table 1). All cases link back to chains of transmission in hotspot areas, with onward local transmission observed in a limited number of towns and villages within family/social networks or health centers where cases have visited prior to their detection and isolation.
