Drwy gydol y pandemig COVID-19, gweithiodd y Gwasanaeth Iechyd Gwladol (GIG) yng Nghymru yn eithriadol o galed i gadw'r feirws allan o'n hysbytai a diogelu pobl a oedd yn derbyn gofal mewn amgylchiadau heriol. Er gwaethaf gweithdrefnau rheoli trylwyr, ac oherwydd bod y feirws yn hynod drosglwyddadwy, cafwyd heintiadau COVID-19 nosocomiaidd (a gafwyd yn yr ysbyty). Yn anffodus, mewn rhai o’r achosion hyn, bu farw unigolion a chafodd eraill niwed.
Throughout the COVID-19 pandemic the NHS in Wales worked incredibly hard to keep the virus out of our hospitals and to protect people who were being cared for in challenging circumstances. Despite rigorous control procedures, but due to the high transmissibility of the virus, there were incidents of nosocomial (hospital acquired) COVID-19 infections and sadly, in some cases, people came to harm or died.
