While studies have examined the effects of large-scale disasters on disaster-vulnerable individuals, these analyses may not capture the full impact. This study qualitatively explored the impacts of the March 2011 Fukushima triple disaster on patients with breast cancer and their families, aiming to highlight the importance of incorporating family narratives to grasp the full effect of large-scale disasters.

Utilizing the medical records from two hospitals, deceased patients with breast cancer from the disaster period were identified. Relatives were interviewed using a semi-structured approach. Thematic analysis was conducted via the Braun and Clarke method and Taguette transcription software.

Interviews with seven family members of six patients revealed three main themes: the family’s caregiving burden and their deepened bonds with the patient, the patients’ extensive medical challenges and their physical and mental decline, and the shared confusion during the disaster due to resource shortages and evacuation dilemmas.

This study uncovered significant infrastructural issues such as reduced medical support and the heavy caregiving load on families, amidst some strengthened relationships during a time of crisis. Future research should investigate these issues across various disaster contexts, and proactive measures should be implemented to prevent exacerbation of these challenges.

Animals, including arthropods, are one health threat that can be affected by disasters. This institution-based study aimed to assess trends in Hymenoptera stings following the 2011 Fukushima nuclear disaster.

We reviewed the medical records of patients with hymenopteran stings who visited Minamisoma Municipal General Hospital, located 23 km from Fukushima Daiichi Nuclear Power Plant, from March 2005 to March 2016. Patient and sting characteristics of post-disaster patients were examined, and the annual incidence of hospital visits for hymenopteran stings was compared with the pre-disaster baseline, calculating an incidence rate ratio (IRR) for each year.

We identified 152 pre-disaster patients (2005-2011) and 222 post-disaster patients (2011-2016). In the post-disaster period, 160 males (72.1%) were identified, with a median age of 59 years (range: 2-89 years). A total of 45 patients (20.3%) were decontamination workers. Post-disaster increases were found in the IRR for hymenopteran stings, peaking first in 2011 (IRR: 2.8; 95% confidence interval [CI]: 1.9-4.2) and later in 2014 (IRR: 3.2; 95% CI: 2.4-4.3) and 2015 (IRR 3.3; 95% CI: 2.5-4.4).

Long-term increases were found in the IRR of hospital visits for hymenopteran stings in an institution affected by the Fukushima nuclear disaster. Decontamination workers appear to have been particularly affected by this phenomenon. Better disaster field worker monitoring and education about potential environmental health hazards may help to identify and prevent worker exposure to insect stings and other vectors in these settings.
