CDC data reinforce current guidelines that health care providers should test liver recipients for hepatitis B at four to six weeks post-transplant. Providers should also consider additional testing again at one year post-transplant or at any time signs or symptoms of viral hepatitis develop, even if previous tests were negative. During 2014–2019, CDC received 20 reports of hepatitis B among recipients of liver transplants from donors who had no evidence of past or current hepatitis B at the time of organ recovery. While hepatitis B infection related to organ transplantation remains rare, these data reinforce the importance of following current U.S. Public Health Service Guidelines. Clinicians caring for recipients of organs from donors who injected nonprescription drugs or who had hepatitis C should be aware of the risk, although low, of unexpected donor-derived hepatitis B virus infection in these patients.

People who have had COVID-19 might experience continued poor physical and mental health and need additional support and tailored rehabilitation services. Health care systems and providers should be prepared to recognize and meet the ongoing needs of these patients. Maximizing vaccination for all eligible people will prevent COVID-19 and post-COVID-19 conditions. Using data from the Select Medical network, including 36 states and the District of Columbia during January 2020–March 2021, CDC assessed patient-reported measures of physical and mental health, physical endurance, and use of health care services among people who had COVID-19 (post-COVID-19 patients) and were referred to outpatient rehabilitation. Comparisons were made with patients referred for cancer rehabilitation in the same network and time frame (control patients). Post-COVID-19 patients who were referred to outpatient rehabilitation reported substantially poorer health at intake compared with control patients, including poorer physical health, more pain, and greater difficulty with physical activities. Patients recovering from COVID-19 might need additional clinical support, including tailored physical and mental health rehabilitation services.
