Early introduction of peanut protein reduces allergy prevalence by approximately 80%, with efficacy diminishing as introduction is delayed. Appropriate prevention involves ingestion of approximately 2 g of peanut protein weekly for infants at low risk and 4 to 6 g weekly for infants at high risk. Population-level implementation that targets all infants achieves greater reduction in disease burden than approaches that target only high-risk groups, although disparities exist among some ethnic groups and groups with restricted access to care. Peanut immunotherapy initiated in younger children (1 to 3 years of age) shows superior efficacy and higher rates of clinical remission as compared with immunotherapy initiated in older children. The natural history of untreated peanut allergy follows a trajectory of increasing peanut-specific IgE levels and clinical reactivity over time, underscoring the importance of early intervention during this narrow developmental window.

Anti-CD19 chimeric antigen receptor (CAR) T-cell therapy is a standard treatment for relapsed or refractory B-cell non-Hodgkin lymphomas. Long-term results and curative potential remain uncertain.

Safer, more effective treatment regimens for rifampicin-resistant tuberculosis are needed.

Bundibugyo virus is a relatively rare orthoebolavirus that has caused only two previously recognized disease outbreaks but remains capable of producing severe epidemic disease with substantial mortality. The 2026 outbreak of Bundibugyo virus disease in the Democratic Republic of Congo has highlighted persistent challenges in the detection of filovirus disease outbreaks, as well as in diagnosis, clinical management, and the public health response, particularly in resource-limited settings. As with other filovirus infections, effective control of the Bundibugyo virus disease outbreak depends on rapid identification of cases, laboratory confirmation of infection, isolation of cases, contact tracing, infection-prevention measures, protection of health care workers, and community engagement. Although no licensed vaccines or approved therapeutics specific to Bundibugyo virus disease are currently available, advances in supportive care have improved outcomes during recent filovirus disease outbreaks. Experimental evidence from studies involving nonhuman primates, serologic investigations with human samples, and monoclonal antibody research suggests that vaccines and therapeutics developed against Ebola virus may provide cross-protective activity against Bundibugyo virus. These observations support prototype-pathogen approaches to preparedness while underscoring the need for continued development of pathogen-specific countermeasures. The current outbreak reinforces the principle that a successful response to filovirus disease requires integration of medical countermeasures, clinical care, surveillance, diagnostics, and coordinated multinational public health operations.
