Being COVID-19 positive and then dying causes a slew of personal, familial, and social issues for family members. Therefore, the current study was carried out to analyze the lived experiences and issues of COVID-19 victims' families in Tehran, Iran. The phenomenological approach was used in the qualitative analysis of 21 first-degree relatives of COVID-19 victims. From August 22 to October 21, 2020, data was gathered by phone (4 people) and in-person (17 people) using semi-structured interviews. The subjects were chosen through purposeful and snowball sampling. The MAXQDA-2018 program was used to organize the data, and the Colaizzi analytical technique was used to analyze it. Guba and Lincoln’s criteria were also used to assess the findings' quality. After analyzing the data, 2 main categories and 14 subcategories were extracted, including (1) challenges in caring for a COVID-19 patient (being rejected, limited access to medical facilities, dissatisfaction with the behavior of medical staff, disruption of family life, the challenge of managing family members' behavior with the patient, and living with doubts and worries (2) challenges after a COVID-19 patient’s death (incomplete farewell to the corpse, unbelievability of the death, ambiguity and tension in the burial process, lonely burial, the twinge of conscience, worry about not respecting the deceased, incomplete condolences, and abandonment). The troubles of victims' families can be ameliorated by developing the skills of caring for COVID-19 patients at home, providing medical and psychological services to families before and after the patient’s death, appropriately informing the families to guarantee them about dignity and respect and respect of the deceased at the interment, and developing a culture of virtual condolence to provide emotional support to survivors.
