In June 2019, two people died of Ebola in neighbouring Uganda.In July 2019, an infected man travelled to Goma, home to more than two million people. One week later, on 17 July 2019, the WHO declared the Ebola outbreak a global health emergency, the fifth time such a declaration has been made by the organisation. A government spokesman said that half of the Ebola cases are unidentified, and he added that the current outbreak could last up to three years.On 25 June 2020, the second biggest EVD outbreak ever was declared over. 2020 Équateur province
On 1 June 2020, the Congolese health ministry announced a new DRC outbreak of Ebola in Mbandaka, Équateur Province, a region along the Congo River. Genome sequencing suggests that this outbreak, the 11th outbreak since the virus was first discovered in the country in 1976, is unrelated to the one in North Kivu Province or the previous outbreak in the same area in 2018. It was reported that six cases had been identified; four of the people had died. It is expected that more people will be identified as surveillance activities increase. By 15 June the case count had increased to 17 with 11 deaths, with more than 2,500 people having been vaccinated. The 11th EVD outbreak was officially declared over on 19 November 2020. By the time the Équateur outbreak ended, it had 130 confirmed cases with 75 recoveries and 55 deaths.
Dysplasia in the myeloid series is defined by:

Granulocytic series:
Hypersegmented neutrophils (also seen in vit B12/folate deficiency)
Hyposegmented neutrophils (pseudo Pelger-Huet)
Hypogranular neutrophils or pseudo Chediak-Higashi (large azurophilic granules)
Auer rods – automatically RAEB II (if blast count < 5% in the peripheral blood and < 10% in the bone marrow aspirate); also note Auer rods may be seen in mature neutrophils in AML with translocation t(8;21)
Dimorphic granules (basophilic and eosinophilic granules) within eosinophils
Erythroid series:
Binucleated erythroid precursors and karyorrhexis
Erythroid nuclear budding
Erythroid nuclear strings or internuclear bridging (also seen in congenital dyserythropoietic anemias)
Loss of e-cadherin in normoblasts is a sign of aberrancy. PAS (globular in vacuoles or diffuse cytoplasmic staining) within erythroid precursors in the bone marrow aspirate (has no bearing on paraffin-fixed bone-marrow biopsy). Note: one can see PAS vacuolar positivity in L1 and L2 blasts (FAB classification; the L1 and L2 nomenclature is not used in the WHO classification)
Ringed sideroblasts (10 or more iron granules encircling one-third or more of the nucleus) seen on Perls Prussian blue iron stain (>15% ringed sideroblasts when counted among red cell precursors for refractory anemia with ring sideroblasts)
Megakaryocytic series (can be the most subjective):
Hyposegmented nuclear features in platelet producing megakaryocytes (lack of lobation)
Hypersegmented (osteoclastic appearing) megakaryocytes
Ballooning of the platelets (seen with interference contrast microscopy)Other stains can help in special cases (PAS and naphthol ASD chloroacetate esterase positivity) in eosinophils is a marker of abnormality seen in chronic eosinophilic leukemia and is a sign of aberrancy.
