Implementing self-care education for prevention in these patients is a priority. This study aimed to investigate the effect of telenursing education on self-care behaviors that prevent COVID-19 in cancer patients.<br> <strong>Methods</strong>: This interventional study was conducted at Vasei Sabzevar Hospital on patients with various types of cancer undergoing chemotherapy and radiation therapy in 2020 coinciding with the second peak of COVID-19, for one month (30 minutes daily). Two-stage sampling was conducted in the intervention group (31 participants) and the control group (26 participants). Self-care and patient follow-up training on the prevention of COVID-19 were conducted through WhatsApp. Data were collected using a researcher-made self-care questionnaire, a demographic questionnaire, and a medical information form.&nbsp;<br> <strong>Results</strong>: The mean age of the participants was 58.24&plusmn;13.27 years, with the majority being female (n=35; 61%). Breast cancer was the most common cancer among the studied subjects (n=24; 42.1%). In the intervention group, the mean score of self-care before the intervention was 21.65&plusmn;8.72 and after the intervention, it was 36.76&plusmn;3.14. The results of the independent t-test showed a significant difference between the two groups (P<0.001). Fisher&rsquo;s exact test did not indicate a significant difference between the two groups in terms of COVID-19 morbidity (P=0.118).&nbsp;<br> <strong>Conclusion</strong>: The results of the present study showed that telenursing education improves self-care behaviors in the prevention of coronavirus in cancer patients.&nbsp;<br> &nbsp;</div> Self-care, Education, Cancer, COVID-19, Prevention 155 164 http://jrh.gmu.ac.ir/browse.php?a_code=A-10-2218-1&slc_lang=en&sid=1 Fateme Borzoee borzoee75026@yahoo.com 1 100319475328460039889 No Department of Operating Room, Non-communicable Diseases Research Center, Faculty of Paramedicals, Sabzevar University of Medical Sciences, Sabzevar, Iran.
