Dylai pawb fod yn ymwybodol o symptomau mpox, waeth beth yw eu cyfeiriadedd rhywiol neu eu rhywedd. Fodd bynnag, mae rhai grwpiau mewn mwy o berygl: dynion hoyw, deurywiol a dynion eraill sy'n cael rhyw gyda dynion sy’n cael eu heffeithio’n bennaf gan y brigiad o achosion presennol. Os ydych yn meddwl bod gennych symptomau mpox dylech gysylltu â GIG 111 neu ffonio clinig iechyd rhywiol ar unwaith, ac osgoi cyswllt personol neu rywiol agos ag eraill nes eich bod wedi trafod â gweithiwr meddygol proffesiynol.
Everyone should be aware of the symptoms of mpox regardless of sexual orientation or gender, however some groups are at increased risk the current outbreak is primarily affecting gay, bisexual and other men who have sex with men (GBMSM).  If you think you have mpox symptoms you should contact NHS 111 or call a sexual health clinic immediately, and avoid close personal or sexual contact with others until you’ve been consulted a medical professional.
