The grief caused by loved ones’ death causes grief is a global phenomenon. The Covid-19 pandemic caused significant changes in human lifestyles and the experience of grief. The purpose of the present study was to compare grief experiences in the deceased's relatives caused by Covid-19 and non-Covid-19. Seventy-five first- and second-degree relatives of the deceased infected with Covid-19 (n = 33) and non-Covid-19 (n = 42) in a Gorgan hospital in northern Iran were included cross-sectional study using convenience sampling. Data were collected using the GEQ-34 grief experience questionnaire and demographic variables and questions related to funeral and burial. The results revealed that the deceased's burial quality caused by the Covid-19 group was significantly lower (p = 0.035). However, the feeling of the Covid-19 label is significantly higher (p <0.001). There was no significant variation in grief's broad experience between the two groups (P > 0.05). Nevertheless, the experience of grief was significantly different in the group of relatives of the deceased infected by Covid-19 in terms of notoriety (P = 0.040) and physical reactions (p = 0.002). Educational interventions to reduce stigma and discrimination due to death caused by Covid-19 and clinical and psychological support of relatives of the deceased due to Covid-19 are recommended by compiling appropriate messages from different channels.
