Mae haint COVID-19 nawr yn destun ymchwil ledled y byd, ac wrth i’r pandemig barhau, rydym yn dod i ddeall mwy am broses y clefyd a’i effaith fwy hirdymor ar iechyd y claf. Y gred i ddechrau oedd y gallai symptomau bara rai wythnosau ac y gallai’r unigolyn, ar ôl i’r symptomau gilio, fynd yn ôl at ei ffordd arferol o fyw, ond mae hi bellach yn dod i’r amlwg bod rhai pobl yn teimlo effeithiau llawer mwy hirdymor.
COVID-19 infection is now a global topic of research, and as the pandemic continues, we are understanding more about the disease process and its longer term impact on patient health. Whilst initially it was thought that symptoms could last a few weeks and, once they subsided, the individual could return to their previous lifestyle, it is now becoming apparent that some people experience much longer term effects.
