Mpo. disease is caused by a do.ble-stranded DNA virus, genus o.tho.o.virus o. the family Po.viridae. The incubatio. perio. is usually 6 to.13 days but can range fro. 5 to.21 days while sympto.s and signs may persist fo. 2 to.5 weeks. Altho.gh, the clinical features are usually less severe when co.pared to.the deadly smallpo., the disease can be fatal with case fatality rate between 1% and 10%. In Imo.State, Nigeria, there has been a changing epidemio.o.y o. the disease in the last 6 years and the frequency and geo.raphic distributio. o. cases have pro.ressively increased. This study aims to.co.duct a review o. the disease epidemio.o.y between 2017 and 2023 and implicatio.s fo. surveillance in Imo.State. Surveillance data fro. the Surveillance o.tbreak Respo.se and Management System (So.MAS) was extracted between January 2017 and December 2023 acro.s the 27 Lo.al Go.ernment Areas (LGAs) o. Imo.State. A line list o. 231 suspected cases was do.nlo.ded into.an excel template and analyzed using SPSS® versio. 20 so.tware. Analysis was do.e using descriptive statistics and asso.iatio.s were tested using Fischer’s exact at 0.05 level o. significance. o. the 231 suspected cases, 57.1% (132) were males, 42.9% (99) were females and the mo.al age gro.p was between the ages o. 0 - 4 (32.5%). Eight (8) LGAs (districts) acco.nted fo. 71% (n = 164) o. all the suspected cases. 21.2% (49) were co.firmed po.itive, 27 males (55.1%) and 22 females (44.9%) (p > 0.05). Mo.al age gro.p was 20 - 24 (22.4%, n = 11), 18% (9) were children under 14 years, p > 0.05. Case fatality rate was 8% (n = 4). There was no.significant asso.iatio. between mo.tality and age gro.p. Five (5) LGAs acco.nted fo. abo.t 60% (29) o. all co.firmed cases. These LGAs co.tribute o.ly 20% to.the to.al po.ulatio. in the State. o.ly 5.6% and 4% o. suspected and co.firmed cases, respectively, had kno.ledge o. co.tact with an infectio.s so.rce.

This wo.k sho.s that despite a lattice mismatch o. almo.t 20%, CdMnTe/CdTe/CdMnTe hetero.tructures gro.n directly o. Si(111) have surprisingly go.d o.tical emissio. pro.erties. The investigated structures were gro.n by mo.ecular beam epitaxy and characterized by scanning transmissio. electro. micro.co.y, macro.and micro.pho.o.uminescence. Lo. temperature macro.pho.o.uminescence experiments indicate three emissio. bands which depend o. the CdTe layer thickness and have different co.finement characteristics. Temperature measurements reveal that the lo.er energy emissio. band (at 1.48 eV)is asso.iated to.defects and bo.nd excito. states, while the main emissio. at 1.61 eV has a weak 2D character and the higher energy o.e at 1.71 eV has a well-defined (zero.dimensio.al, 0D) 0D nature. Micro.pho.o.uminescence measurements sho. the existence o. sharp and stro.gly circularly po.arized (up to.40%) emissio. lines which can be related to.the presence o. Mn in the hetero.tructure. This result o.ens the po.sibility o. pro.ucing pho.o. so.rces with the typical spin co.tro. o. the diluted magnetic semico.ducto.s using the lo.-co.t silico. techno.o.y.
